Pick up almost any “thyroid support” supplement and turn it around. Odds are you’ll find a long, impressive-looking list — fifteen, twenty ingredients — often hidden inside a “proprietary blend.” The logic is clear: more looks like more. The more ingredients, the more impressive the bottle.
We made the opposite choice. Here’s why.
The problem with a long list of token doses
When you spread a supplement’s capacity across twenty ingredients, something has to give: the dose of each individual ingredient. And dose matters. The clinical evidence for selenium reducing thyroid antibodies used 200 mcg (Gärtner et al., 2002). The myo-inositol and selenium combination used 600 mg myo-inositol + 83 mcg selenium per dose, twice daily (Nordio & Basciani, 2017). You can’t spread those alongside twenty other ingredients and still hit the numbers that the research supports.
What “depth over breadth” means in practice
Thyrolume is built around a small number of ingredients chosen because they have the strongest, most direct evidence for the specific problems of Hashimoto’s and thyroid dysfunction:
- Myo-inositol — for TSH signaling and well-being
- L-selenomethionine — for antibody reduction and T4→T3 conversion
- Active B-vitamins (methylfolate + methylcobalamin) — for the many women with MTHFR variants and B12 depletion
- Zinc bisglycinate — for conversion and immune support
- Acetyl-L-carnitine — for cellular energy production
- NAC — for antioxidant defense of thyroid tissue
- Black pepper extract (Piperine) — to support absorption across the stack
Each ingredient is at a dose that matches or approaches the evidence. No padding. No proprietary blends. You can look up every dose on the label and cross-reference it against the research.
A long list of tiny doses is a label strategy. A short list of real doses is a formula strategy. We chose the formula.
Frequently asked questions
Why do thyroid supplements have so many ingredients? Often to look impressive on the shelf. But more ingredients in a fixed space means smaller doses of each — frequently below what research used. A shorter list dosed properly usually does more.
What is a proprietary blend and why avoid it? A proprietary blend lists a group of ingredients with only the total weight, hiding how much of each is included. It lets a brand imply a strong dose while using very little. Full transparency (each ingredient listed individually) is better for you.
Why isn’t magnesium in the main formula? A meaningful dose of magnesium glycinate is bulky and would crowd out the core thyroid stack. We’d rather keep the core doses intact and offer magnesium separately.
Does Thyrolume contain iodine or biotin? No to both — iodine because it can worsen Hashimoto’s, and biotin because it can interfere with thyroid blood tests.
