Grapefruit seed extract (GFSE) is a potent anti-fungal which can be used to prevent and control fungal overgrowth such as Candida albicans, that can result from use of long term antibiotics (both herbal and prescription). Also, studies show that GFSE is an effective inhibitor of the cyst form of spirochetes. This high potency formula has 500mg of standardized GFSE per capsule which decreases the amount of capsules needed to achieve results. Best taken on an empty stomach mid- am and mid-afternoon but can be taken any time.?
