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. 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. One serving (1 softgel) of Ultra Strength RxOmega-3 provides 600 mg of EPA and 300 mg of DHA omega-3 fatty acids for convenient 'all you need is one per day'.

Ultra Strength RxOmega-3 Enteripure softgels offer targeted delivery using a technology that embeds pure and natural ingredients into the softgel casing to prevent them from breaking down in the stomach, ensuring no fishy aftertaste. Ultra Strength RxOmega-3 is also available without vitamin D3.

iHerb Customer Reviews

Very High strength formula

Posted by iHerb Customer on Dec 15, 2017 | Verified Purchase

We use this for cognitive assistance in a child with special needs - the ratio of DHA/EPA greatly improves thinking ability. The price point when mixed with Vitamin E and EPO is really great, when compared to others. I find it works great for me as well (really good concentration and brain power for the day) so long as I don't over do it. Capsules are on the large size, so they may need to be opened if a problem. Oil is not bad tasting, but the high strength can repeat a little. Overall a good product at a really great price if this sort of product works for you.

Thanks for your feedback!

Good product!
