Best fish oil I have used! Thank you, Natural Factors!

This is a great brand compared to others. You get higher dose of EPA/DHA given you take only one softgel and the DHA/EPA ratio is the optimal. It has very faint fish smell and it's easy to swallow. It's molecularly distilled & guaranteed for purity and has clean quality ingredients, no fillers and no artificial flavors. It helps improve my brain function & memory Protects my heart & lowers inflammation. Helps reduce serum triglycerides and the pain of rheumatoid arthritis. Be aware that you should take it with meals that contain fats as it needs digestive enzymes and bile. Consider giving a thumbs up if you found this review helpful.

400 EPA (anti-inflammatory) + 200 DHA (brain health)

The major key strength of this fish oil compared to other brands: Pharmaceutical Grade Fish Oil Concentrate, Molecularly Distilled (guaranteed purity, no environmental pollutants). The oil is primarily extracted from smaller varieties of fish, like anchovies, sardines and mackerel (not endangered fish and contain fewer toxins than the larger species). EPA+DHA are shown to lower triglycerides by 30 percent.

Good

I’ve been ordering from iHerb for over a year now, and it’s become my go-to place for supplements and natural skincare. Prices are almost always lower than local stores, and they frequently have discounts or loyalty credits that make it even more affordable.

很好!

Every month, I have to buy a lot of things. If I were to evaluate them one by one, I would be very frustrated. So I specially made a template. When you see this passage, it means I am very satisfied with this product. Later buyers can purchase it with confidence. Of course, I am not an irresponsible buyer. If the product is not good, I will also take the time to review it carefully

Review of Omega3

Have seen improvement in our overall physical checkups after taking the Natural Factors Omega 3 sofgels. The sofgels seam to digest easily and our doctor states they are much better for our digestive system than capsules. My wife and I are both over 70 and feel better since taking the Omega 3 sofgels and we both agree it has been beneficial to our health. Quality of product is excellent and ingredients have not had any negative impact to our digestive system.

Omega 3

I’ve been taking **RxOmega-3** capsules for about two months now, and I couldn’t be more satisfied. The product feels very high quality — the fish oil is ultra-purified, so there’s no fishy aftertaste or burps. ([DeliHerb][1]) I take one softgel a day (as recommended) and feel like it’s really supporting my overall wellbeing. My joint stiffness has noticeably lessened, and I feel better in terms of cardiovascular health and mental clarity. I also appreciate how clean the formula is: the manufacturer uses molecular distillation to eliminate contaminants like heavy metals. ([ROZETKA][2]) The capsules are easy to swallow, and I like that they’re free from common allergens. ([ROZETKA][2]) Overall, **RxOmega-3** has become a staple in my daily routine. Highly recommended if you’re looking for a reliable, potent omega-3 supplement.

Everyone should take there omega 3's, and this is one of my favorite brands

Big package with quality omega supplement. With clean fish oil as the main ingredient, I’ve noticed real benefit for heart health, lower cholesterol, less inflammation, and even stronger hair. Beneficial for any age. The taste is mild, making it easy to take daily.

Omega 3 Rx the best

This Omega is a really good product; it's truly one of the best brands. We've tried it as a family, and it works wonders for our children. I also like that it's not too expensive and has been tested to be chemical-free. Very good.
