Recommended brand at a great price

Natural Factors is a highly regarded brand for Omega-3 fatty acids and the RxOmega-3 Ultra Strength contains over 2 gm per 2 caps. This product has DPA in addition to DHA/EPA which is a plus, and at a great price. So many benefits to supplementing with Omega-3s since the average person doesn't consume enough "fatty" fish.

Easy to digest and effective

These fish oil capsules are exactly as described — very easy to digest and gentle on the stomach. I haven’t experienced any unpleasant aftertaste or fishy burps, which is a big plus. I’m almost finished with the bottle and have been satisfied with the quality so far. Would consider purchasing again.

Good

I’ve been shopping on iHerb for a few months now, and every order has been smooth and reliable. Most recently, I purchased California Gold Nutrition Omega-3 and Herbal Immune Support Tea. Both products arrived in perfect condition, well-packaged, and with expiration dates that are far into the future — something I really value when buying supplements online.

High-quality pharmaceutical-grade product. Each capsule packs 900 mg of active fatty acids, which is super convenient — no need to take handfuls. No fishy aftertaste at all. Top-notch for heart and joint health."

No Fishy Burps at All

Really impressed with this Omega-3. The EPA/DHA ratio is solid, the purity is noticeable, and the enteric coating means zero fishy burps — none. It’s gentle on my stomach and easy to take even on busy days. I’ve also noticed my mood and focus feel a bit more stable, especially on long screen-time days. Didn’t expect it, but my skin also feels slightly less dry. Overall, this has become one of my reliable daily supplements.

Huge softgels, but manageable

I have been taking Omega 3 soft gels for several years and switched to this brand because of the higher strength of EPA and DHA. I was kind of shocked to see how huge the softgels are and you need to take two of them per day. But I have found that very manageable and feel confident that this product is delivering the dose I was looking for.

Potent ingredient, great benefit

I’ve been taking this supplement for a year now and it’s excellent. The purity, quality, formula, and potency — everything is top-notch. It has reduced inflammation, improved my overall health, and supports healthy cholesterol levels. There’s no fishy taste, which is a big plus. I definitely recommend it!
