The best raw material is fish collagen, which is far away from pollution sources and contains no hormones, so it is safer and healthier to take.
The purity of the powder is relatively high. Oral liquid, capsule and beverage all contain additives and preservatives, and the content of collagen in them cannot be determined.
The smaller the molecular weight of collagen, the easier it is to be absorbed by human body. The molecular weight of general products is about 3000 daltons, and there are several good ones. Higher-end products can reach 65,438+0,000 daltons, such as Meryl collagen. 65,438+0,000 Dalton is the most stable and effective, with good absorption and natural effect.
