Thyroid Tune-Up: Healthmasters' Thyroid Support

Your thyroid may be small, but it is the “conductor” that sets the tempo for every cell in the body. Shaped like a butterfly at the base of the neck, this little gland makes two hormones—T4 and T3—that tell each cell how quickly to burn energy. To build those hormones, the thyroid needs three key nutrients:

• Iodine (the spark that starts hormone-making)
• Tyrosine (an amino acid that forms the hormone’s backbone)
• Selenium (a mineral that “polishes” T4 into its active form, T3)

When any of these nutrients run low, you can feel tired, cold, foggy, or notice weight creeping up. Healthmasters’ Thyroid Support combines ocean seaweeds that supply gentle, food-based iodine with L-selenomethionine (a natural form of selenium), L-tyrosine, and carefully prepared gland “concentrates” from grass-fed cattle. Together, these ingredients feed not just the thyroid but its partner glands—pituitary, adrenals, thymus, and spleen—so that your whole hormone network stays in tune.

Iodine — the spark plug of thyroid hormone

Each T4 molecule carries four iodine atoms; each T3 carries three. Iodine shortage is the leading cause of slow thyroid worldwide. Classic research shows that just a short course of kelp (seaweed) equal to about 250 µg of iodine a day nudges thyroid-stimulating hormone (TSH) upward in healthy people—clear proof that iodine in kelp reaches the thyroid fast [1]. In people whose sluggish thyroid came from low-iodine diets, one to two grams of powdered kelp daily (about 400 µg iodine) brought both urine-iodine levels and TSH back to normal within weeks [2].

Seaweed does more than fix deficiency; it also delivers iodine in a form the body likes. A 2023 Norwegian crossover trial gave healthy young women a sushi meal that included wakame seaweed (about 230 µg of iodine). Within just a few hours, their urine-iodine levels climbed sharply and stayed elevated for most of the next day, confirming that seaweed eaten as part of an ordinary meal can provide a swift, meaningful boost to iodine status without upsetting thyroid-hormone balance [3].

Arctic studies confirm that wild seaweed iodine is absorbed easily and shows up in urine tests [4]. Just four grams (about a teaspoon) of dried Irish moss gives a child roughly one-quarter of a full day’s iodine need [5].

Selenium — the mineral that activates thyroid hormone

Once T4 leaves the gland, special enzymes—made with selenium—snip off one iodine atom to turn T4 into its active partner, T3 [6]. A 2024 review of many trials found that selenium supplements in people with Hashimoto’s thyroiditis (an autoimmune form of slow thyroid) consistently lowered TSH, reduced thyroid-attacking antibodies, and eased oxidative stress, which is a form of cell “rusting” [7]. Longer studies using 100–200 µg of L-selenomethionine daily showed antibody counts dropping month after month, and people felt better overall [8]. Each Thyroid Support capsule gives 50 µg—enough to plug common diet gaps without passing safe limits.

L-Tyrosine — the amino-acid building block

Tyrosine is the “backbone” for each hormone molecule. Under stress, the body also turns tyrosine into adrenaline, which means less may be left over for the thyroid. In a demanding military-training study, cadets who took two grams of tyrosine in drinks five times a day had sharper memory and quicker reactions than cadets on dummy drinks [9]. A larger review found tyrosine helps thinking skills when people face cold, noise, or mental strain—times when T3 levels often dip [10]. Every capsule supplies 30 mg, a small but steady top-up that works alongside iodine.

Sea-vegetable synergy: dulse, Irish moss, and bladderwrack

Red and brown seaweeds do more than bring iodine. Their natural fibers and sulfur-rich sugars feed helpful gut bacteria and may calm runaway immune activity. Bladderwrack in particular contains fucoidans—plant compounds that fight oxidation and swelling in test-tube studies. Thyroid Support uses food-like amounts of each seaweed (400 mg dulse, 40 mg Irish moss, 15 mg bladderwrack), well under the large, multi-gram doses linked to rare iodine overload or thyroid swelling [11] [12] [13].

Glandular concentrates—time-tested endocrine nourishment

For nearly a century, nutrition experts have used freeze-dried animal organs to supply tiny amounts of peptides (short proteins) and trace nutrients missing from modern diets. This formula includes purified bovine thyroid (150 mg), adrenal (50 mg), anterior pituitary (15 mg), thymus, and spleen (5 mg each). While prescription thyroid pills contain high hormone doses, these low, food-level concentrates focus on micronutrients and natural peptides only.

A head-to-head study of prescription-strength desiccated thyroid extract (DTE) versus the usual drug, levothyroxine, showed that nearly half of the participants preferred DTE, citing better weight control and no extra side-effects [14].

How the pieces fit together

• Building blocks – Iodine-rich kelp, dulse, Irish moss, and bladderwrack supply the sparks; L-tyrosine supplies the structure.
• Activation and protection – L-selenomethionine helps flip storage hormone (T4) into active T3 and shields the gland from cell “rust.”
• Team players – Adrenal and pituitary concentrates add peptides that may support the brain-thyroid “command chain,” while thymus and spleen concentrates bring gentle immune balance.
• Gentle balance – Food-based nutrients respect the body’s feedback loops instead of forcing them.

Together, these ingredients help recreate the mineral-rich environment in which the thyroid evolved to thrive. Many users say they notice warmer hands and feet, steadier energy, and clearer thinking within two to four weeks, though timing varies.

Safety first

Because the thyroid is sensitive to both shortage and overload, Thyroid Support keeps iodine moderate (40 µg per capsule). People can start with one capsule a day and see how they feel, or take two for extra support. Anyone already on prescription thyroid medicine—or with Graves’ disease or over-active thyroid—should talk with a health professional before adding iodine. Pregnant women should stick with doctor-approved prenatal vitamins.

The bottom line

Modern life floods us with processed foods, stress, and environmental chemicals that can throw our hormones off track. Re-introducing gentle, food-based iodine, selenium, tyrosine, and time-tested glandular concentrates can help the thyroid regain its rhythm. Healthmasters’ Thyroid Support offers a balanced, natural way to help support a healthy thyroid so one can feel energetic, focused, and in tune.
