A deeper look at the active ingredients in Collagen Fit:

Collagen Peptides

Thorne's Collagen Fit contains 15 grams of types I and III, grass-fed, hormone-free collagen per serving. Collagen is rich in the amino acids that function as the building blocks for the body’s bones, muscles, ligaments, tendons, skin, and other connective tissues.* Collagen peptides, also known as collagen hydrolysate, undergo a unique process that breaks collagen into shorter amino acid chains (peptides) that are easier to digest, as well as being free of the harsh chemicals used in other mainstream collagen products. 

Benefits of collagen peptides:

• Nutrient support for joints, muscles, bones, and skin*
• Improves activity-related or exercise-induced joint pain*
• Promotes the growth of lean muscle mass*
• Supports muscle repair and recovery*
• Strengthens connective tissue*
• Enhances skin, hair, and nail health*

Nicotinamide Riboside (NR)

Both normal aging and a modern lifestyle – lack of sleep, excessive stress, an unbalanced diet – lead to a declining level of NAD⁺ in the body. NR increases the body’s natural production of NAD⁺, a coenzyme that is a key component in the production of cellular energy.* 

Benefits of NR:

• Boosts the natural production of NAD⁺ to resist the effects of aging*
• Supports exercise efficiency – helping you reach your health and fitness goals*
• Promotes healthy mitochondria, which enhances cellular energy production*
• Supports the normal sleep-wake cycle*
• Enhances cellular repair and metabolism*
• Provides optimal benefit for athletes, competitors, and individuals seeking healthy aging support*

Betaine

A superior methyl donor, betaine, also known as trimethylglycine, supports the body’s natural methylation processes.

Benefits of betaine:

• Improves NR function by providing methyl groups to enhance metabolism of NAD⁺*
• Supports training and recovery*
• Promotes lean body composition*
• Helps maintain a healthy level of homocysteine in the blood, which promotes cardiovascular and cognitive health*
