Give your body a nitric oxide boost to optimize your energy and stamina with Swanson Fast-Acting Beet Root NO+ Chewable Nitric Oxide Support. Your physical energy and endurance depend largely upon your body’s supply of nitric oxide, which helps relax blood vessels to improve circulation and enhance the delivery of oxygen to muscle tissues. Our Beet Root NO+ Chewable Nitric Oxide Support gives you the nutritional building blocks to optimize your nitric oxide production and maximize your stamina. The formula starts with beet root, one of nature’s richest sources of nitrates, which the body converts into nitric oxide. Supplementing nitrates may help maintain blood pressure levels already within the normal range. Adding to this is L-arginine, which has earned a reputation as a “fitness amino” because it is the primary base material for the body’s natural nitric oxide production. The amino acid L-citrulline serves as an L-arginine precursor, extending the supply available for nitric oxide production for longer-lasting circulatory support. To complement the activity of these nitric oxide precursors, the formula includes beta-alanine, an amino acid that enhances muscle carnosine levels to help fend off fatigue. For optimal effectiveness and convenience, we combined this synergistic blend of fatigue-fighters in great-tasting, naturally cherry flavored, sugar-free chewable tablets that deliver the nutrients quickly for a fast-acting energy boost.
