There comes a point when “try harder” stops being useful health advice.
You are eating better.
You are training consistently.
You care about your health.
Maybe you track your food, take supplements, prioritize protein, walk every day, lift weights and try to get enough sleep.
Yet something still feels off.
Your energy is unpredictable. Your digestion seems different. Losing body fat feels harder than it used to. Your recovery has slowed down. You may notice changes in your menstrual cycle, sleep, mood, hunger, temperature tolerance or mental clarity.
And sometimes the most frustrating part is hearing that everything looks “normal.”
That gap between putting in the work and understanding what is actually happening inside the body is one reason the new partnership between Tiffany Marie Davis, founder of TM Wellness, and 1st Optimal makes sense.
Tiffany’s approach is built around nutrition, lifestyle, digestive wellness, hormone-supportive habits, recovery and structured coaching. Her TM Method is designed for people, particularly high-performing women, who feel as though their body is no longer responding to the strategies that once worked. Tiffany’s own website describes a framework that considers nutrition, digestion, stress, recovery, blood sugar support, training and lifestyle rather than simply telling people to exercise harder or eat less.
The partnership with 1st Optimal adds another layer: access to advanced bloodwork, hormone and thyroid evaluation, gut-health testing, licensed medical providers and individualized clinical care when appropriate. The 1st Optimal Partnership Program specifically provides partners access to advanced labs, hormone and thyroid care, gut-health testing, metabolic health services and functional medicine backed by licensed medical professionals.
The goal is not to turn coaching into medicine.
And it is not to reduce health to a laboratory report.
It is to connect the pieces.
Tiffany can continue helping clients implement nutrition, lifestyle, training and recovery strategies while the 1st Optimal medical team handles the clinical side, including medically appropriate testing, interpretation, evaluation and treatment.
For someone who has spent months or years wondering why their body suddenly feels different, that combination can create something valuable:
More information. More context. And a clearer plan for what to do next.
Who Is Tiffany Marie Davis?
Tiffany Marie Davis is the founder of TM Wellness, where her work focuses on nutrition education, lifestyle strategy, hormone-supportive habits, digestive wellness, body composition, metabolism and long-term energy.
Tiffany identifies herself with the credentials CNP, LEHP and CPIS and describes her work as helping high-performing women and men who are putting in the effort but feel that their body is no longer responding the way it once did.
She also brings a unique perspective from the fitness world.
Tiffany has been publicly described as a nutrition practitioner, peptide integration specialist and former IFBB professional athlete. Her background gives her firsthand exposure to the difference between looking healthy from the outside and understanding what may be happening internally.
That distinction matters.
Someone can be lean and still feel exhausted.
Someone can train five days a week and still struggle with recovery.
Someone can follow an aggressive diet and watch their digestion, menstrual cycle or performance deteriorate.
Someone can appear disciplined while quietly feeling like their body is fighting them.
That is why Tiffany’s current TM Wellness message is not based on simply adding more exercise or greater restriction.
Her TM Method focuses on four broad phases: root-cause exploration, stabilization, rebuilding and optimization. The framework looks at lifestyle, nutrition, digestion, stress, recovery and behavioral patterns, then works toward more sustainable nutrition, training and wellness habits.
Now, the 1st Optimal partnership can add clinical information to that conversation when it is appropriate.
Why the Tiffany Davis and 1st Optimal Partnership Matters
One of the biggest challenges in health coaching is knowing where coaching ends and medicine begins.
A coach might recognize that a client seems unusually fatigued.
A nutrition practitioner might notice that a woman’s cycle has changed.
A trainer might see that a client is suddenly struggling to recover from training.
A client may report constipation, bloating, unexplained weight changes, hair thinning, night sweats, sleep disruption, low libido or persistent brain fog.
Those observations matter.
But they are not diagnoses.
Fatigue, for example, can occur for dozens of reasons. Thyroid dysfunction is one possibility, but so are iron deficiency, inadequate calorie intake, sleep disorders, medications, nutrient deficiencies, metabolic issues, stress, depression and many other conditions.
That is where medical collaboration becomes important.
Through the 1st Optimal partnership model, coaching professionals can maintain their relationship with clients while licensed clinicians handle medical evaluation and treatment.
1st Optimal describes its model as functional health coaching powered by functional medicine. The company combines advanced testing, clinical evaluation and individualized medical care with nutrition, exercise, sleep, stress-management and accountability support.
For Tiffany’s community, this creates a clearer path when lifestyle optimization alone does not answer every question.
Instead of choosing between coaching and medical care, the client can potentially benefit from both.
Hormones, Thyroid and Gut Health Are Different Systems, but They Do Not Operate in Isolation
One of the reasons people struggle to understand persistent symptoms is that the body does not organize itself into the neat categories we use in healthcare.
Hormones are not separate from metabolism.
Thyroid hormones do not operate separately from energy regulation.
Gut health does not exist independently from nutrition.
Sleep can influence appetite and glucose regulation.
Diet can influence gastrointestinal function.
Menopause can affect body composition, sleep, mood, metabolic health and potentially the gut microbiome.
Stress can influence behaviors, recovery and gastrointestinal symptoms.
That does not mean every symptom is caused by a mysterious “hormone imbalance” or an unhealthy microbiome.
It means context matters.
Hormone Health Is More Than One Number
People searching for hormone testing for women, hormone imbalance testing, perimenopause hormone testing or functional hormone testing often want a single laboratory result to explain how they feel.
Human physiology is rarely that simple.
For example, sex hormones commonly evaluated in women can include estradiol, progesterone, testosterone, sex hormone-binding globulin, DHEA-S, LH and FSH. Depending on the situation, clinicians may also evaluate thyroid markers, metabolic markers, iron status, blood counts, glucose regulation and other health indicators.
1st Optimal currently offers women’s laboratory panels that may assess sex hormones alongside thyroid, metabolic, cardiovascular, blood and nutrient markers. More comprehensive panels can include total and free testosterone, estradiol, progesterone, SHBG, DHEA-S, cortisol, TSH, free T3, free T4, fasting insulin, HbA1c, lipid markers, ferritin, iron, vitamin D and additional biomarkers.
But more testing does not automatically mean better medicine.
For women experiencing a typical menopausal transition, for example, ACOG notes that routine hormone testing usually is not required simply to establish that perimenopause is occurring. Symptoms, menstrual changes, age and medical history often provide more useful clinical context.
The better question is not:
“How many hormones can we test?”
It is:
“Which information would actually help answer the clinical question in front of us?”
That is an important difference.
Thyroid Health: Why Symptoms Need Context
Thyroid health is another major focus of the Tiffany Davis and 1st Optimal partnership.
The thyroid produces hormones that play an important role in energy utilization, metabolism, temperature regulation and the normal function of multiple organs.
Hypothyroidism occurs when the thyroid does not produce enough thyroid hormone. Symptoms can include fatigue, feeling cold, constipation, dry skin and cognitive or mood changes, but those symptoms are not unique to thyroid disease. The American Thyroid Association emphasizes that laboratory testing is needed to determine whether hypothyroidism is actually present.
TSH, or thyroid-stimulating hormone, is commonly used as the first-line thyroid screening test.
And for good reason.
A normal TSH makes primary hypothyroidism less likely in many people.
But depending on the patient’s history and the clinical question, a provider may decide that additional thyroid information is useful.
1st Optimal’s more comprehensive testing options can include TSH, free T4, free T3, thyroid peroxidase antibodies and thyroglobulin antibodies.
Additional thyroid testing may help clinicians investigate specific questions involving thyroid hormone production or possible autoimmune thyroid conditions such as Hashimoto’s thyroiditis or Graves’ disease.
The important point is that laboratory values should be interpreted in context.
Feeling tired with a normal TSH does not automatically mean someone has a hidden thyroid disorder.
It also does not mean their fatigue should simply be ignored.
The next step may involve looking at sleep, nutrition, iron status, medications, blood sugar, other laboratory markers or additional clinical possibilities.
Better testing should lead to better questions, not simply more diagnoses.
Gut Health: Moving Beyond Random Supplements
The phrase gut healing has become extremely popular online.
Unfortunately, so has the idea that nearly every symptom originates in the gut.
The reality is more nuanced.
The gastrointestinal tract plays essential roles in digestion, nutrient absorption, immune function and interactions with the trillions of microorganisms that make up the gut microbiome.
People may experience legitimate gastrointestinal symptoms including bloating, constipation, diarrhea, abdominal discomfort, reflux and changes in bowel habits.
The problem is what often happens next.
They start guessing.
One probiotic.
Then another.
A digestive enzyme.
An extreme elimination diet.
A “gut detox.”
Several expensive supplements.
Maybe they eliminate gluten, dairy, grains, legumes and half of their favorite foods without ever knowing whether those restrictions are necessary.
Testing can sometimes help bring more structure to the process when a clinician determines that it is appropriate.
One of the gut-health tools available through 1st Optimal is GI-MAP testing, a stool-based test that uses quantitative PCR technology to evaluate specific microbial DNA targets and gastrointestinal markers. Certain panels may include markers related to pathogens, commensal organisms and intestinal health.
But this distinction matters:
A gut test is information. It is not a diagnosis by itself.
Finding an organism on a stool panel does not prove that it explains every symptom.
Results must be interpreted alongside the person’s medical history, symptoms, medications, diet and other clinical information.
That is also why the medical component of the Tiffany Davis x 1st Optimal partnership matters.
Testing should inform a strategy.
It should not replace clinical judgment.
The Emerging Hormone and Gut Health Connection
The relationship between hormones and the gut microbiome has become a major area of scientific interest, particularly in women’s health.
Researchers increasingly recognize that the relationship can work in both directions.
Hormones may influence microbial communities, while gut microorganisms participate in metabolic processes involving certain hormones.
One area of interest is the estrobolome, a collection of microbial genes involved in estrogen metabolism.
Recent research reviews have reported associations among menopause, estrogen changes and differences in the gut microbiome. However, the science is still evolving, and researchers have not identified a universal “perfect” microbiome for women or proven that changing the microbiome will resolve hormone-related symptoms.
A 2026 review examining diet, the gut microbiome and estrogen physiology highlighted this potentially bidirectional relationship while emphasizing that more longitudinal research is needed to determine exactly how diet, microbiome patterns and symptoms interact during perimenopause.
That nuance is important.
There is enough evidence to take gut health seriously.
There is not enough evidence to blame every hormone symptom on “dysbiosis.”
The practical takeaway is much simpler:
Hormones, gastrointestinal health, nutrition, metabolism, stress, sleep and lifestyle deserve to be considered together when the individual’s symptoms suggest that a broader evaluation may be useful.
That philosophy fits naturally with both TM Wellness and 1st Optimal.
What Functional Testing Can Add to the Picture
Functional testing works best when it answers a specific question.
Not:
“Let’s test everything.”
But:
“Based on this person’s symptoms, history and goals, what information could change what we do next?”
Depending on the individual, that evaluation might involve several categories.
1. Hormone Testing
Potential markers may include:
- Estradiol
- Progesterone
- Total testosterone
- Free testosterone
- SHBG
- DHEA-S
- LH
- FSH
- Prolactin
- Cortisol when clinically appropriate
These results are interpreted alongside symptoms, life stage, menstrual status, medical history and other relevant information.
2. Thyroid Testing
Depending on the clinical situation, testing may include:
- TSH
- Free T4
- Free T3
- Thyroid peroxidase antibodies
- Thyroglobulin antibodies
Not every person needs every marker.
The goal is to answer relevant clinical questions.
3. Metabolic Testing
Hormone symptoms and metabolic symptoms frequently overlap.
A clinician may consider markers such as:
- Fasting glucose
- Fasting insulin
- Hemoglobin A1c
- Lipid panel
- ApoB
- Lipoprotein(a)
- Liver function
- Kidney function
- High-sensitivity CRP
These markers can provide useful information about glucose regulation, cardiovascular risk and broader metabolic health.
4. Nutrient and Blood Health
Fatigue or poor performance is not automatically hormonal.
A broader evaluation may consider:
- Complete blood count
- Ferritin
- Iron
- TIBC
- Transferrin saturation
- Vitamin D
- Vitamin B12 or folate when appropriate
These results can help clinicians investigate other possible contributors to symptoms instead of assuming every problem originates with estrogen, testosterone or thyroid hormones.
5. Gut-Health Testing
When gastrointestinal symptoms or clinical history justify deeper evaluation, advanced stool testing such as GI-MAP may be considered.
1st Optimal currently offers GI-MAP with zonulin testing as one of its available gut-health tools.
Again, testing is only useful when the result is placed in context.
The objective is not more data for the sake of data. It is useful data that supports better decisions.
How the Tiffany Davis x 1st Optimal Partnership Can Work
The strength of this partnership is that Tiffany and the medical team do not have to perform the same role.
They should not.
Instead, each side can focus on what it does best.
Step 1: Start With the Person, Not the Lab Panel
The first question should not be:
“What test should I buy?”
It should be:
“What has changed?”
Symptoms, health history, nutrition, training, sleep, digestion, stress, previous laboratory results, medications, menstrual history and personal goals all create context.
For Tiffany’s clients, this fits naturally into the TM Method, which already considers nutrition, digestion, recovery, lifestyle structure, stress and daily habits.
Step 2: Identify When Medical Evaluation Could Add Value
Some challenges belong primarily in coaching.
Others deserve medical investigation.
And many sit somewhere between the two.
That is where collaboration becomes powerful.
If symptoms suggest that thyroid function, metabolic health, hormone health or another medical issue deserves evaluation, a licensed medical provider can determine what testing or clinical assessment is appropriate.
Step 3: Use Targeted Testing
The medical team can order appropriate laboratory testing based on the individual.
That may involve basic or comprehensive bloodwork.
In other situations, optional advanced testing such as GI-MAP or DUTCH testing may be considered when clinically useful. 1st Optimal states that comprehensive bloodwork serves as a foundation while optional advanced tests can be added depending on the situation.
Step 4: Medical Interpretation and Treatment
A laboratory report should never be treated like an online personality quiz.
Results require interpretation.
The clinician considers symptoms, medical history, medications, physical health, risk factors and other relevant information before recommending next steps.
When prescription treatment or hormone therapy is medically appropriate, the licensed medical team is responsible for that clinical decision and ongoing medical management.
1st Optimal’s Partnership Program states that treatment plans are supported by licensed providers and that prescription medications may be recommended when clinically appropriate.
Step 5: Turn the Plan Into Daily Action
This is where coaching remains critical.
Knowing what to do and actually doing it consistently are different things.
Someone may know that strength training matters.
They may understand that sleep matters.
They may know they need enough protein or fiber.
They may even have an excellent treatment plan.
But none of those recommendations produce meaningful change unless they can be implemented consistently.
Tiffany’s role can help bridge that gap through nutrition education, lifestyle strategy, training support, recovery habits and accountability.
Step 6: Reassess Instead of Guessing Forever
Health is dynamic.
Nutrition changes.
Stress changes.
Training changes.
Hormones change across different stages of life.
Medication may change.
Symptoms may improve, worsen or evolve.
That is why 1st Optimal describes its approach as ongoing rather than static, using symptoms, laboratory data, treatment response and progress to determine when care should be adjusted.
Why White-Label Medical Services Matter for Wellness Professionals
The Tiffany Davis partnership also illustrates a broader change happening across the coaching and wellness industry.
Clients increasingly want more information.
They want labs.
They want hormone support.
They want gut-health testing.
They want help understanding why their body feels different.
But a coach should not have to become a physician to meet those needs.
And they should not practice outside their scope to remain competitive.
That is where the 1st Optimal white-label partnership model becomes valuable.
Through its Coaching Partnership Program, 1st Optimal provides access to medical infrastructure that wellness professionals typically cannot or should not recreate on their own.
The program includes access to advanced testing, hormone and thyroid care, gut-health testing, functional medicine, licensed medical oversight and white-label fulfillment. The partnership program is designed for nutrition coaches, functional health coaches, personal trainers, gym owners, performance coaches, wellness practitioners and related professionals.
In practical terms:
The coach keeps coaching.
The clinician practices medicine.
And the client does not have to navigate those worlds completely alone.
For health and fitness professionals, this model may also provide a pathway to expand services without building an entire clinical organization from scratch.
That means not having to independently construct laboratory relationships, medical documentation systems, provider networks, prescription-management processes and clinical monitoring infrastructure.
It is one reason white-label functional medicine and medical-backed coaching are becoming increasingly relevant for established wellness brands.
Who Could Benefit From the Tiffany Davis and 1st Optimal Approach?
There is no universal testing protocol or treatment plan for every person.
But this type of integrated approach may appeal to someone who recognizes experiences like:
- “I train consistently, but my recovery has changed.”
- “My body composition is changing even though my routine hasn’t changed much.”
- “I’m constantly tired and I don’t know why.”
- “I feel like my hormones changed after 35 or 40.”
- “My periods or menstrual symptoms have changed.”
- “I’m going through perimenopause and want more support.”
- “I keep experiencing bloating, constipation or digestive discomfort.”
- “I have thyroid-related symptoms and want to discuss appropriate testing.”
- “My basic labs looked normal, but I still do not feel like myself.”
- “I want to better understand my metabolic health.”
- “I want medical oversight alongside my nutrition and lifestyle coaching.”
- “I’m tired of trying random supplements without understanding what I actually need.”
None of those statements confirms a diagnosis.
They are starting points for better questions.
And sometimes that is exactly what people have been missing.
Symptoms Are Signals, Not Diagnoses
This may be one of the most important principles behind the partnership.
Your symptoms deserve attention.
But they also deserve context.
Fatigue does not automatically mean hypothyroidism.
Weight gain does not automatically mean low estrogen.
Bloating does not automatically mean “leaky gut.”
Brain fog does not automatically mean a hormone disorder.
Difficulty losing weight does not automatically mean insulin resistance.
At the same time, those symptoms should not simply be dismissed because someone looks healthy, exercises regularly or received one normal laboratory result.
The most responsible approach sits between those extremes.
Listen.
Ask better questions.
Test when testing is likely to be useful.
Interpret the data in context.
Treat what is medically appropriate to treat.
Improve the lifestyle factors that can realistically be improved.
Then reassess.
That is much more useful than either dismissing every symptom or blaming every symptom on one biomarker.
Why This Partnership Feels Like a Natural Fit
Tiffany’s message to her community is clear:
More pressure is not always the answer.
Her TM Method was designed for people who are already trying.
They are not looking for another crash diet.
They are not looking for a seven-day detox.
They are not looking for someone to tell them they simply need more discipline.
They want to understand their body better and build a strategy that can work in real life.
1st Optimal approaches the clinical side from a similar direction.
Rather than separating medical treatment from nutrition, exercise, sleep, stress and daily behavior, the company describes its model as bringing functional health coaching and functional medicine into a connected system.
That means the Tiffany Davis x 1st Optimal partnership is not simply about ordering more lab tests.
It is about connecting information with implementation.
Tiffany brings education, coaching, nutrition, lifestyle strategy and accountability.
1st Optimal brings advanced testing, licensed clinical evaluation, hormone and thyroid care, gut-health evaluation and medical oversight.
Together, the objective is a clearer understanding of the individual.
Not a one-size-fits-all program.
Not another generic meal plan.
Not another supplement stack copied from social media.
And not medicine without lifestyle support.
Frequently Asked Questions About Tiffany Davis x 1st Optimal
What is the Tiffany Davis and 1st Optimal partnership?
The partnership connects Tiffany Davis and TM Wellness’ nutrition and lifestyle coaching approach with 1st Optimal’s medical infrastructure. Depending on individual needs, clients may have access to advanced bloodwork, hormone and thyroid evaluation, gut-health testing, functional medicine providers and medically appropriate treatment while continuing to receive lifestyle and coaching support.
Does Tiffany Davis provide medical treatment?
Tiffany’s TM Wellness work focuses on nutrition, lifestyle, digestive wellness, hormone-supportive habits, recovery and coaching. Medical evaluation, prescribing and clinical treatment through the 1st Optimal partnership are handled by licensed medical professionals.
That distinction helps protect the role of both the coach and the clinician.
What hormone tests does 1st Optimal offer?
Available panels vary. Depending on the test and clinical situation, markers can include estradiol, progesterone, testosterone, SHBG, DHEA-S, LH, FSH, cortisol and prolactin alongside thyroid and metabolic markers.
The right panel depends on the individual and the clinical question being investigated.
Does everyone need hormone testing during perimenopause?
No.
For many women experiencing a typical menopausal transition, hormone levels do not need to be measured simply to confirm perimenopause. Hormone concentrations can fluctuate substantially during this stage, and major medical guidance emphasizes symptoms, menstrual history, age and medical context.
Laboratory testing can still be valuable when another condition is being considered or when the results could meaningfully affect clinical decisions.
What is included in a more complete thyroid panel?
Depending on clinical need, thyroid testing may include TSH, free T4, free T3 and thyroid antibodies such as thyroid peroxidase and thyroglobulin antibodies.
TSH remains an important and useful thyroid test. Additional markers may be considered when a healthcare professional determines they could clarify a specific clinical question.
What is GI-MAP testing?
GI-MAP is a stool-based gastrointestinal test that uses qPCR technology to analyze specific microbial DNA targets and other gastrointestinal markers.
It can provide information that may be useful when evaluated alongside symptoms and medical history, but it should not be viewed as a standalone diagnosis or proof that every detected organism is responsible for someone’s symptoms.
Can hormone health affect gut health?
Hormones and the gut microbiome appear to interact, and researchers are actively studying the relationship between estrogen, menopause and the gut microbiome.
Current research supports biological connections between these systems, but there is still much to learn. There is not a single microbiome pattern that defines hormonal health, and gut-focused interventions should not be promoted as a universal treatment for hormonal symptoms.
Does a normal TSH mean every symptom is normal?
A normal TSH makes primary hypothyroidism less likely for many people, but it does not explain every possible cause of fatigue, weight change, brain fog or poor recovery.
A healthcare professional may consider other possibilities, including iron status, sleep, nutrition, medications, metabolic health or other medical conditions depending on the individual.
What are 1st Optimal’s white-label medical services?
The Coaching Partnership Program allows qualified coaches and wellness professionals to integrate access to advanced laboratory testing, medical evaluation and related clinical services without trying to provide those medical services themselves.
1st Optimal’s public partnership program describes access to white-label fulfillment, advanced labs, hormone and thyroid care, gut-health testing, medical oversight and marketing support.
Is the program only for women?
No.
Tiffany works with both women and men, although many aspects of her positioning address women navigating hormonal and body-composition changes. 1st Optimal offers separate care pathways addressing women’s and men’s hormones, metabolic health, weight management and gut health.
Stop Guessing. Start Asking Better Questions.
One of the hardest places to be with your health is knowing that something feels different but not knowing what to do next.
You can spend months changing supplements.
Changing diets.
Changing workouts.
Cutting calories.
Adding cardio.
Removing foods.
Searching symptoms online.
Trying another wellness trend.
And still never answer the question that mattered in the first place:
What information do I actually need to make a better decision?
That is the opportunity behind the Tiffany Davis x 1st Optimal partnership.
Tiffany and TM Wellness bring an approach grounded in nutrition, lifestyle structure, digestive wellness, recovery, training and sustainable behavior.
1st Optimal adds access to advanced hormone testing, thyroid evaluation, metabolic bloodwork, gut-health testing and licensed medical care.
The objective is not to medicalize every symptom.
It is not to order every test available.
And it is not to convince you that one hormone, one food or one microorganism explains everything happening in your body.
It is to create a more connected path between the way you live, the symptoms you experience, the information available from appropriate testing and the medical care you may need.
Because sometimes the answer is better nutrition.
Sometimes it is better recovery.
Sometimes training needs to change.
Sometimes sleep and stress are driving more of the problem than expected.
Sometimes a symptom deserves a medical evaluation.
And sometimes several of those things are happening at the same time.
That is why connected care matters.
Tiffany brings the coaching and lifestyle strategy.
1st Optimal brings the functional testing and medical team.
You get a clearer picture of what deserves attention and a more informed path forward.
