Four synergistic ingredients combine to counteract stress and promote restful sleep. The formula starts with Relora, a patented herbal blend that helps normalize stress-related hormones. The next ingredient is Suntheanine L-Theanine, a patented amino acid (derived from green tea) that promotes mental and physical relaxation. Rounding out the formula are melatonin and ZMA, a vitamin and mineral blend made up of zinc, magnesium and vitamin B-6.
