The active ingredient of this fruit, (-)hydroxycitric acid (HCA), has been standardized for maximum potency. HCA has been shown to curb appetite in numerous animal studies. CITRIMAX utilizes both ChromeMate and chromium picolinate for broad spectrum chromium supplementation. L-Phenylalanine is a precursor to key neurotransmitters.
