The generally recommended daily collagen intake varies depending on the type of collagen supplement and the health benefit sought, but research suggests the following ranges:

• Hydrolyzed collagen peptides: 2.5 to 15 grams per day is considered safe and effective. Lower doses around 2.5 grams daily may benefit joint pain and skin hydration, while doses of 5 grams may improve bone density, and higher doses up to 15 grams can help with muscle mass and body composition

• Undenatured collagen: Typically, 10 to 40 milligrams per day are used for improving joint health

• Gelatin: Used more as a food ingredient than a supplement, with no specific dosage guidelines; follow package instructions if used as a supplement

For women specifically, studies show:

• About 1650 mg (1.65 grams) daily can improve skin hydration and elasticity

• Higher doses around 20 grams per day may benefit digestive health

• Evidence for bone health benefits at 10 grams per day is less conclusive

Most collagen supplement products suggest taking 1-2 scoops or capsules daily, but since collagen content varies by product, it is important to check the nutrition label for exact amounts

. In summary, a daily intake of 2.5 to 15 grams of collagen peptides is widely regarded as safe and effective for general health benefits related to skin, joints, bones, and muscles. The exact amount depends on the form of collagen and your health goals
