Overview
•High biotin dosage (10,000 mcg) is generally safe but may interfere with lab tests for thyroid and hormone levels; consult a doctor if undergoing bloodwork.
•Contains fish collagen, posing allergy risk for those with fish sensitivities; includes nuts (coconut), which may affect nut-allergic individuals.
•Vitamin A at 1,200 mcg RAE (133% DV) is within safe limits but chronic high intake could lead to hypervitaminosis A; suitable for adults but caution in pregnancy.
•B-vitamins at elevated doses (e.g., B6 5 mg, 294% DV) are water-soluble and low risk, though long-term high B6 may cause neuropathy in sensitive users.
•No major drug interactions noted, but MSM and nettle may mildly interact with blood thinners; overall formulation GRAS for healthy adults.
•Gluten-free and non-GMO, low contamination risk from US manufacturing, but verify third-party testing for heavy metals in collagen sources.
