Doctor-Suggested Testing
Vitamin D (25-OH Vitamin D)
Why Vitamin D Testing Matters
Vitamin D plays a vital role in immune function,
cellular regulation, inflammation balance, and
metabolic health. Because vitamin D functions more
like a hormone than a simple vitamin, symptoms
alone cannot reliably indicate deficiency or
insufficiency.The 25-hydroxyvitamin D [25(OH)D]
blood test is the gold-standard marker used in both
clinical practice and research to assess vitamin D status.
What Research Shows
Large global studies evaluating vitamin D blood levels have demonstrated a strong inverse association between serum vitamin D levels and the risk of breast and colorectal cancer.
Key findings include:
-
An estimated 600,000 cases per year of breast and colorectal cancer worldwide could potentially be prevented with adequate vitamin D intake
-
Nearly 150,000 cases annually in the United States
-
Protective effects beginning at 25(OH)D levels of 24–32 ng/mL
-
Earlier research suggesting levels closer to 55 ng/mL may be optimal for cancer prevention
-
The average late-winter vitamin D level in the U.S. is approximately 15–18 ng/mL, well below levels associated with benefit
Vitamin D levels vary widely due to geography, season, sun exposure, age, skin pigmentation, and lifestyle, making testing essential.

Vitamin D Supplementation (If Needed)
If your lab results indicate supplementation is appropriate, we offer high-quality vitamin D3 through our online store: Opti Vitamin D 5,000 IU
Supplementation should always be guided by lab results and individual needs, not assumptions.
Comprehensive Thyroid & Hormone Panel
Why Thyroid Testing Matters
The thyroid plays a central role in metabolism, energy production, heart rate, weight regulation, temperature balance, and hormonal signaling. Thyroid imbalances can present with subtle or overlapping symptoms, making comprehensive testing particularly valuable.
This panel evaluates multiple markers of thyroid function, offering a more complete picture than single-marker testing alone.
Tests Included
Reverse T3 (rT3)
An inactive thyroid hormone that does not stimulate metabolism. It is produced to help clear excess T4 from the body and may rise during stress or illness.
Free T3
Measures the active thyroid hormone available to tissues; used to evaluate thyroid function and monitor therapy.
Free T4
Measures unbound thyroxine, especially useful when protein abnormalities may affect total T4 levels.
TSH (Thyroid Stimulating Hormone)
A primary marker for thyroid regulation.
-
High TSH may indicate underactive thyroid function
-
Low TSH often suggests overactive thyroid function or, less commonly, pituitary-related dysfunction
TPO Antibodies (Thyroid Peroxidase Antibodies)
Assesses autoimmune activity affecting the thyroid and the enzyme essential for thyroid hormone production.
DHEA-S
A precursor hormone for estrogen and testosterone; also plays a role in immune function and stress response.
