Formulation Notes

Ultra Strength RxOmega-3 with 25 mcg (1000 IU) vitamin D3 is a pharmaceutical-grade fish oil providing one of the most powerful strengths of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) available. One serving (1 softgel) provides 600 mg of EPA and 300 mg of DHA omega-3 fatty acids.

Molecularly distilled and guaranteed for purity and safety from environmental pollutants like PCBs and mercury or other harmful compounds, RxOmega-3 surpasses the strictest international standards for quality.
