Choline, Inositol and Methionine are the lipotropic factors that metabolize fats and cholesterol and aid in the transportation of fat in the blood system. Methionine also increases dopamine, norepinephrine and serotonin and acts as a natural anti-depressant. Chromium Picolinate maintains normal blood sugar levels, which is essential for fat loss. L-Carnitine transports fatty acids to the mitochondria where they are processed to be used up for energy.
