Professional Health Products Selenomethionine delivers selenium in its organic, amino acid-bound form — one of the most bioavailable dietary forms of this essential trace mineral. Selenomethionine supports antioxidant enzyme activity, healthy thyroid function, and immune system maintenance, making it a practical option for those with identified selenium insufficiency or increased physiological demand.
Why It's Worth Considering: Selenomethionine is absorbed more efficiently than inorganic selenium forms (such as selenite or selenate), and Professional Health Products formulates to practitioner-grade standards with straightforward ingredient profiles.
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.
