Madre Labs produce the cheapest fish oil supplement out there yet it is somehow more effective. I took some fish oil supplement before by various brand but nothing seems to change on my daily health. I am tempted to try the Madre Labs fish oil as it is one of the most reviewed supplement on amazon.com and it's very cheap. There is a slight change in my mood when taking this fish oil. Why need expensive supplement when you can get cheaper one that works. You gotta try it - anyway you won't lose so much money.
