One daily serving of NIAGEN® is now in one capsule rather than two. Each capsule in your recent shipment contains a daily serving of Tru Niagen®, which is 300mg. We received numerous requests for fewer capsules per serving. And, when our customers started asking for fewer capsules per serving, we listened. With half the capsules in a 30-day supply, we were also able to introduce a smaller, more environmentally friendly bottle.
