The amount of collagen you should take a day varies depending on the type of supplement

The amount of collagen you should take a day varies depending on the type of collagen supplement you are taking and why you are taking it. There are no official guidelines as to how much collagen should be taken per day.

Generally, for improved skin and hair health, 2.5-10 grams of collagen peptides can be taken orally for 8-12 weeks daily. For arthritis, 10 grams of collagen peptides can be taken daily in 1-2 divided doses for about 5 months.

What are common types of collagen supplements?

The most common types of collagen supplements include:

  • Hydrolyzed collagen: Derived from bovine (cattle), seafood, poultry, pigs and other sources. This is the most common form of collagen supplement because it can be rapidly absorbed by the body. Hydrolyzed collagen is available in capsule or powder form, and a study has shown that taking 2.5-15 grams of it each day may be effective for skin, bone and hair health.
  • Undenatured collagen: Derived from chicken cartilage. Some studies have indicated that taking 10-40 milligrams of undenatured collagen per day can significantly improve joint health.
  • Gelatin: Derived from animal sources and mostly used for cooking as an ingredient in gelatinous desserts. Gelatin can be mixed in sauces, soups, smoothies and other foods for a boost of collagen proteins.

Often, the packaging may suggest taking 1-2 scoops of a powdered supplement or 1-2 pieces of a pill or gummy supplement daily. However, since collagen content may vary significantly depending on the formulation of the supplement, make sure to check the nutrition facts label for detailed dosage information.
