Thyrafemme Balance Review: What Is in the 14-Ingredient Thyroid Formula?

What Thyrafemme Balance is

Thyrafemme Balance is a capsule sold at getthyrafemme.com, with ClickBank processing the order. The label names the distributor as PhytoThrive Labs of Aurora, Colorado, the company behind Fluxactive Complete. It is marketed to women as a “Moon Elixir” for “feminine thyroid harmony”, with steadier energy, mood, metabolism, hair and skin among the promised benefits. The directions are two capsules a day, preferably with a meal.

What is in it

Unlike most products we review, the label lists every ingredient with its amount. Per two capsules (30 servings a bottle):

• Selenium (amino acid chelate) 200 mcg
• Iodine (from kelp) 150 mcg
• Vitamin B12 (cyanocobalamin) 100 mcg
• Magnesium (oxide) 200 mg
• Zinc (oxide) 8 mg
• Copper 0.2 mg, manganese 2 mg and molybdenum 50 mcg
• L-tyrosine 300 mg
• Schisandra fruit 240 mg
• Ashwagandha root 200 mg
• Bladderwrack 50 mg, cayenne 30 mg and kelp 15 mg

Kelp and bladderwrack are seaweeds that contain iodine. The label gives their weight but not how much iodine they add on top of the 150 mcg.

What the evidence shows

• Selenium: a 2024 meta-analysis of 35 studies in people with Hashimoto’s thyroiditis, the most common cause of an underactive thyroid in countries with enough iodine, found that selenium lowered thyroid peroxidase antibodies, and slightly lowered TSH in people not yet taking thyroid hormone. Thyroid hormone levels did not change, and the certainty of the evidence was moderate. An earlier Cochrane review called the clinical relevance of the antibody changes unclear. The 200 mcg in Thyrafemme matches the dose used in many of those trials; it is half the adult upper limit of 400 mcg a day, so count any selenium from multivitamins or Brazil nuts.
• Ashwagandha: one 8-week pilot trial in 50 adults with subclinical hypothyroidism, a mildly underactive thyroid, found that 600 mg a day of root extract improved TSH, T3 and T4 compared with placebo. Thyrafemme contains 200 mg, a third of that. Because ashwagandha can raise thyroid hormone levels, it can also overshoot: a 73-year-old woman developed thyrotoxicosis with a fast heart rhythm after two years of taking it for hypothyroidism, which resolved when she stopped.
• Iodine: 150 mcg is the adult daily requirement. A 2019 review found that extra iodine is tolerated by most healthy people but can trigger an overactive or underactive thyroid in some, especially those with existing thyroid disease, sometimes at intakes only slightly above need. It names seaweeds and iodine-containing supplements as sources of excess.
• L-tyrosine: the body makes thyroid hormone from tyrosine, but protein foods supply plenty, and we found no trial showing tyrosine supplements improve thyroid function.
• The rest: vitamin B12, magnesium, zinc and the trace minerals help mainly people who are short of them. Schisandra and cayenne have no thyroid trials.

No study has tested Thyrafemme Balance itself.

Thyroid medicine and thyroid disease

• If you take levothyroxine: minerals such as magnesium, calcium and iron can reduce how much of the medicine you absorb, which is why its leaflet advises taking it on an empty stomach and several hours apart from them; the magnesium in Thyrafemme is magnesium oxide, the form used in antacids. Supplements with iodine, selenium or ashwagandha can also change your thyroid test results. Talk to your doctor before adding this.
• If you have Hashimoto’s or Graves’ disease, or an overactive thyroid: extra iodine and ashwagandha are a particular concern, so ask your doctor first.
• If you have symptoms: tiredness, weight gain, feeling cold, dry skin and thinning hair have many causes. A TSH blood test tells you whether your thyroid is involved, and an underactive thyroid is treated with thyroid hormone. Our hormonal imbalance guide explains the tests.
• Pregnancy: the label says it is not for pregnant or nursing women, or anyone under 18.

What the marketing promises

The sales page headline promises “The Ancient ‘Moon Elixir’ Ritual for Feminine Thyroid Harmony”, and its affiliate material promises to “restart your dead thyroid battery” and “melt stubborn thyroid weight”. Its FAQ answers “Is Thyrafemme Balance really safe?” with “Absolutely”, and the order section warns that this is “the very last time you’ll ever be able to get this”.

Two things on the official site do not match the product. Its “Scientific References” page lists studies on erectile dysfunction, oats, hawthorn and inosine, none of them about the thyroid; it looks copied from a men’s product. And its contact page, which says the full ingredient list is on “the product label below”, shows a second label for ThyraBoost Pro, a different PhytoThrive formula of chromium with green tea, apple cider vinegar, berberine and other herbs. The Thyrafemme Balance label described above is the one that matches the sales page.

Price and refund

There is no single-bottle option. Two bottles cost $158 ($79 each) plus $9.95 shipping in the US; three cost $177 ($59 each) and six cost $294 ($49 each), both with free US shipping and five bonus e-books. It is a one-time payment, not a subscription. The 60-day refund runs from delivery: you return every bottle at your own cost to the warehouse in Aurora, Colorado, and the refund excludes shipping fees. Our Thyrafemme Balance buying guide covers where it is sold and international shipping.

Realistic expectations

For women with Hashimoto’s thyroiditis, selenium at 200 mcg may lower thyroid antibodies, and that is the part of this formula with evidence; whether it makes people feel better is less clear. It will not replace thyroid hormone if your thyroid is underactive, and the iodine and ashwagandha add risks that a plain selenium supplement, taken with your doctor’s agreement, would not.
