Flax seed oil?

Fish oil is good. Proven by science to benefit you

Potassium tablets - why? Have a banana unless you're on it for a diagnosed problem
Flax seed oil... why? What is lacking in your diet? If you eat a reasonably healthy diet with enough fats - nuts, dairy, meat etc then I don't see why you need it! It's expensive

Hope that helps

Thanks for replying dude.

In response, tbh I bought potassium tablets because I use myfitnesspal and always saw I was on like 0% for potassium every day, but at the time didn't realise it was in bananas oops. So technically just finishing the packet lol.
Flax seed oil because I've seen its in a number of body building fitness programs, and the more potassium the more testosterone therefore more gains no?

P.s. I don't eat red meat (don't ask why, just brought up this way not for religious reasons xD) and I've seen my iron levels are low too. Maybe I should ditch potassium and flax seed and go for iron tablets as an alternative? idk man in desperate need of advice here!!
