The bulk versions ofat coscto is good, but, if you want a high grade of epa/dha balance, then buy brand that SHOWS the amount of EPA/DHA that is higher. Costco's brand is 1,000mg with only 300mg of .
That is basically 150mg per, at best, which is inadequate. You would have to take 2 pills 3 times a day to get the "adequate" amount of epa/dha. That's to much filler. Also, the fact that I can't split a pill gives me more of one than I really need because usually, most pills are higher in epa than dha. Or vise versa.
