5 Best Collagen Powders of 2021, According to a Dietitian

Collagen is the main structural protein that forms our body’s connective tissue—such as bone, skin, cartilage, and tendons. It is widely believed that if humans ingest collagen from outside sources, it will support and optimize our health and address physiological needs posed by aging and exercise. You can always visit SYNT to buy the best collagen powders at reasonable rates.

What Experts Say

“Make sure your collagen supplement contains vitamin C. The presence of this important vitamin is necessary for collagen synthesis. And be sure to add antioxidants to your collagen regimen. Collagen fibers are a food source for free radicals, so antioxidant protection is super important, as free radical damage is the number one cause of aging.” —Olivia Pelaez, MS, functional nutritionist, and education coordinator at Vital Proteins
