Take 2 tablespoons a day and get that inflammation down. Use with Acetyl-L-Carnitine for cardiovascular health. Use with Carnosine and turmeric for brain health.

Easy to take

Posted by iHerb Customer on January 8 2018 | Verified Purchase

I decided to try this liquid form of this product a couple months ago in place of the large softgel capsules with the same pharmaceutical grade fish oil I'd been taking for years. I suspected I would not be able to tolerate the taste as a regular part of my daily supplement regimen, and that I would return to taking the capsules. But I actually find this orange flavored oil quite acceptable. I wouldn't call it 'yummy' or 'scrumptiously delicious,' but it's also not at all obnoxious. Of course, all I can say is what's true for my taste buds - I'm sure some people will be more sensitive to it. Because pouring it from the bottle does seem a bit awkward, I just tilt my head back and drizzle about a teaspoon's worth into my mouth and call it good - it's food after all, not a drug that requires precise measurement. I also like that I am able to avoid consuming the large softgel capsules, which are not exactly a garden-fresh natural food, with the possibility of negative effects to my digestive tract over time. And this is the best omega-3 fish oil product I have found - pharmaceutical grade (no heavy metals, PCBs) and high level of omega 3s.

I can't thank you enough for you wonderful product. I have been suffering with Prepheral Neuropathy for the past 7 years with much suffering. My feet were always burning all night long. I have tried many different drugs for a long time with horrible side effects. One of my daughters suggested that I try your fish oil that she buys from a health food store. After a few weeks I started to feel improvement in my neuropathy. Now I'm a new person. I can't believe that I now can sleep through the night. Your fish oil is a wonder for. I'm on my second bottle now. Thank you,Thank you.
