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.

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.

No More popping and creaking joints!

I used to sound like a chiropractor every morning when I woke up, but with these krill oil, I don't pop and click nearly as much as I used to. Also, unlike other Krill Oil supplements, this has zero fish taste or fishy burps. It actually smells like candy so I don't mind taking it at all!

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.

Four Stars

I am very happy with the krill oil. It seems to be equal to Mega Red but at a better price. The only complaint I have with it is it's not USP verified like supplements at COSCO. Something I look for in vitamins & other supplements. That would have made it a 5 star rating.
