Wait for two to three hours after eating before you take collagen pills. Since collagen needs to pass through your stomach and into the intestines without being broken down by stomach acid, collagen supplements must be taken on an empty stomach.
Take two or three 400-milligram collagen supplements with a full glass of water before going to bed. This gives body a chance to absorb and process the collagen during the natural repair time while you sleep.
Eat and drink nothing at all between the time you take the collagen tablets and the time you go to bed. If any food is present in your stomach, your digestive system will begin breaking down the collagen along with the food, making it ineffective.
Give the pills up to two to four months to experience the full benefit. Discontinue their use if not improvements.
