Yes, of course although some are water soluble and the others fat. The ones, if contain too much fat stick in the body and may build to be toxic (extreme doses)
The rest could be expensive urine as they get peed out so to speak (vitamin c etc)
I take around 7 diffrent ones at night from a multi to red krill oil.
I think one i just bought cardioace contains garlic.
Red krill is dear, i would say its worth it, better than standard fish oil.
