Broadly positive for thyroid support and energy, with practitioner backing for sinus/immune use, tempered by clear dosage-limit warnings.
Kelp with Selenomethionine and Iodine from Ecological Formulas/Cardiovascular Research combines natural kelp-derived iodine with selenomethionine — an organically bound, highly bioavailable form of selenium — to support thyroid hormone synthesis and normal thyroid function. This formulation is designed for individuals seeking foundational micronutrient support for metabolic and endocrine wellness.
Why It's Worth Considering: Pairing kelp iodine with selenomethionine (rather than inorganic selenite) may offer improved selenium retention and utilization, reflecting the formulation precision associated with the Cardiovascular Research line.
For maintenance: 100-200mcg daily (selenomethionine form preferred). For thyroid support: 200mcg. The RDA is 55mcg but most functional medicine practitioners recommend 100-200mcg. Do NOT exceed 400mcg/day — selenium has a narrow therapeutic window and excess causes selenosis (hair loss, nail brittleness, GI issues).
Yes — selenium is critical for thyroid function. It's required for the enzyme that converts inactive T4 to active T3, AND it protects thyroid cells from oxidative damage. In Hashimoto's, 200mcg selenium daily reduces TPO antibodies by 20-40% in clinical trials. It's one of the most evidence-based supplements for thyroid health.
One Brazil nut contains 70-90mcg selenium — so 2 nuts/day provides a therapeutic dose. However, selenium content varies dramatically by soil (some nuts have 10mcg, others have 300mcg). If you rely on Brazil nuts, be cautious about overconsumption — 4-5 large nuts could exceed 400mcg. A supplement provides a consistent, known dose.
