Overview
•Omega-3 dosages (300 mg per softgel) are well within safe limits (up to 3g/day recommended by AHA); no risk of bleeding at this level per NIH guidelines.
•Generally safe for healthy adults; enteric-coated softgels minimize fishy aftertaste and GI upset, but consult doctor if on blood thinners like warfarin due to mild anticoagulant effects.
•Low allergen risk for non-fish allergies; product is molecularly distilled to remove mercury and PCBs, reducing heavy metal contamination per USP standards.
•Not recommended during pregnancy without medical advice; while DHA supports fetal development, high doses may affect bleeding risk (Mayo Clinic).
•Suitable for long-term use in adults; monitor for rare side effects like nausea in sensitive individuals, but overall GRAS status from FDA.
•No significant drug interactions beyond blood thinners or antihypertensives; space intake 2 hours from other meds to avoid minor absorption interference.
