    CLA (Conjugated Linoleic Acid)

    Ultra pure, premium grade 1000mg strength CLA capsules from THE PROTEIN WORKS™ offer unparalleled levels of quality and efficacy. Conjugated Linoleic Acid is a unique source of highly concentrated CLA derived naturally from the finest safflowers. This naturally occurring Omega 6 fatty acid cannot be produced by the body and so CLA softgels are the ideal way to boost your levels quickly and conveniently. Widely consumed in sports nutrition and in elite sport, CLA works well with all protein shakes and in particular, when combined with a supplement like Thermopro.
