Nurse Bonnie

It has helped my cholesterol levels since I’ve been taking it for several years now. I recommend it to everyone to try because it’s better than taking the regular fish oil. After just 6 months my levels were way better than when I was just taking the fish oil. These don’t give the after taste either.

Happy purchase!!!

I'm not sure if they are helping my cholesterol yet or not. My dr wanted me to start on krill oil and found Member's Mark. I was worried about the fishy taste, and I'm happy to report NO fish taste at all! Way cheaper than a brand name, too, plus easy to swallow.

Good krill oil

It's hard to find krill oil that doesn't smell awful, taste awful, or DISNEY come back to haunt you! This is great for all the right reasons.

Great Omega-3 Addition to Daily Vitamin Routine

My husband and I have taken Member's Mark Omega-3 Krill Oil for years. We are very happy with the price and the product. we trust the Member's Mark Brand over the many generic choices available.

Quality food supplement.

I switched from fish oil to krill oil several years ago. Krill oil is smaller, much easier to swallow. No After taste. My cholesterol numbers are good. I can’t take statins due to adverse reactions. I feel that Members Mark produces quality supplements that help promote my good health which as a senior, I am much more concerned about.

Build a stronger Immune system by taking this pill

We have been using this Krill oil for years. It is extremely helpful for maiming a healthy immune system. Krill oil is the most bio- available form of Omega 3, because it is in phospholipid form. Very high quality product at exceptionally low price.

Cancer Drug for Herceptin

Have been taking Krill oil since 2016 when I was diagnosed with stage 1V breast cancer. I was told that the herceptin I was to be given every three weeks could damage my heart so I take 1000 mg daily.. All my EKG's every six months show my heart is fine.

Easier to swallow

The size of these pills makes them much easier to swallow than traditional fish oil-omega supplements. I notice no other differences between the traditional and these krill-oil ones, except the price. The higher price makes them less attractive, but if you have pill-swallowing-issues, they are a good option.

I replaced seafood in my diet with these

Since I started using this product in October my blood work for hypothyroidism has greatly improved. We don't know for sure if it is the actual reason for the improvement. I am not promoting this as a medical instrument. Nothing else was added to my diet but after two separate high blood tests in April and August the blood work in December was normal. It will take yet another blood test to see if this trend continues. I have no trouble swallowing these capsules and there does not seem to be any aftertaste.
