has anyone tried/seen effect of omega-3, or b12 (vegetarians) supplements

for me, even a single capsule of OTC (over the counter) vitamin pill of 'cod liver oil' (very little omega-3, but it takes effect within 10 minutes) , shoots up my game 10-20%, i never even knew that i had omega-3 deficiencies, and once i take the pill, i feel a calm, very similar to post-meditation (zazen) effect

p.s. has anyone had similar experiences ?, with omega-3, or any other diet and nutrition affecting game, (tyler takes omega-3 supplements too according to his videos)

... has anyone read the book - 'the ultra mind solutions', or tested out other 'solutions' in the book
