What is considered the best collagen supplement?

The best collagen supplements are those that include the peptides marketed under the brand names Verisol and BioCell, according to Prevention. These are the only collagen-related supplements that can point to scientific studies supporting their claims to reduce wrinkles.

Specific products that contain Verisol and BioCell peptides include Reserverage Organics Collagen Replenish, a powder to add to liquids; Jusuru Liquid BioCell Life Blend, a juice-like liquid taken in 2-ounce doses; and Lindberg Skin Rejuvenator, which comes in pill form. While proteins are normally destroyed in the digestive tract, studies have proven that oral ingestion of these peptides has an effect on the skin, notes Prevention.
