BPI Sports Bpi CLA + Carnitine

Most of this category runs on stimulants, which rules it out for a lot of people - anyone sensitive to caffeine, anyone already taking a strong pre-workout, and anyone who would rather not feel wired all day. This one contains none at all.

It pairs conjugated linoleic acid, drawn from safflower, avocado and coconut oil powders, with three forms of carnitine including L-carnitine tartrate and glycine propionyl L-carnitine. Carnitine's role in the body is transporting fatty acids into the cell to be used for energy, which is why it belongs in a formula meant to support your metabolism alongside training and a sensible diet rather than instead of them.

A tub holds 50 servings, taken as one scoop in 8oz of cold water morning and evening.

It comes in Fruit Punch, and because there is no caffeine in it the evening serving will not keep you awake.
