Marek Supplements Thyroid Support 90-Day Formula

The supplement arm of Marek Health puts its case on the label: Thyroid Support is a one-a-day, 90-day bottle with all 13 ingredient doses disclosed and the current batch's third-party lab results linked from the product page.

Marek Supplements is the house supplement line of Marek Health, the hormone-optimization telehealth and diagnostics company, and the connection is structural rather than cosmetic. The store's own schema lists Marek Health as its parent organization, the bottles carry the Marek Health logo, and every formula is credited to Dr. Steven Campbell, MD, Marek Health's medical director, described on the site as triple board-certified. Thyroid Support wears the brand's own best-seller badge on the homepage, one of five products the store marks that way.

The format is a 90-capsule, 90-day bottle at one capsule per day. The label is fully disclosed with no proprietary blends: 225mcg iodine, 100mcg selenium, 15mg zinc bisglycinate, 600mcg RAE vitamin A, active-form B2 and B6, copper, chromium, plus 100mg black cumin extract, 25mg forskolin, 100mg myo-inositol, 150mg taurine, and 50mg L-tyrosine. The brand describes the formula as supplying nutrient cofactors involved in healthy thyroid hormone production and conversion, and the page carries the standard not-intended-to-diagnose disclaimer. This is a nutrient support formula, not thyroid medication. Each batch is tested by ISO/IEC 17025-accredited labs, the certificate of analysis for the current batch is linked from the product page, and manufacturing is in an NSF/ANSI 455-2 certified US facility.

Where it gives ground: the store is young and thin on social proof. At verification the product showed a 5.0 rating from just 2 reviews, so the best-seller badge rests on a small base. The 30-Day Money Back banner is also narrower than it sounds. The binding refund policy accepts only unopened, unused product within 30 days of delivery, you pay return shipping, and original shipping charges are not refunded, so there is no satisfaction guarantee once a bottle is opened. A single $75 bottle sits under the $99 free-shipping threshold, and shipping covers the US and Canada only. At $0.83 per day one-time or $0.75 subscribed, it costs more than commodity thyroid blends; the disclosed doses and published per-batch testing are what you are paying for.
