Stay healthy
Good pill size, and new lemon flavor. Has all the great omega Three, and fish oil for brain, heart and joints. Good price and quality. Easy to swallow with no bad burping as long as you keep it refrigerated. Works fast and is a great choice.

High Potency Omega-3 and Easy to Take
I’ve been taking this omega-3 supplement and so far I’m very happy with it. The capsules are easy to swallow and I appreciate the high potency of 3600 mg per serving. It feels like a good quality supplement and I like that it helps support overall wellness. The bottle also lasts a long time, which makes it a good value. Overall, it’s a great option if you’re looking for a reliable omega-3 supplement.

Good vitamin
I’ve only just begun taking this vitamin so it’s really too early to tell its efficacy. I did not detect any flavoring including lemon.
