Have been many Omega3 products tested. But none has been proven brought so much success as Olimp Omega3. I let my Omega3 value measured regularly by blood monitoring and only since I take the Omega3 of Olimp, this has risen considerably. As an ambitious athlete, I am currently taking 3 times a day 1 capsule with meals. The slight fishy taste at first belching after a capsule does not bother me. Where genuine fish oil in it, it may also quiet times after taste! ;-) But the effect is guaranteed - and that's what counts!
