Collagen Supplements: Benefits, Types, and What the Science Says
What is Collagen?
Collagen is the most abundant protein in the human body,acting as a crucial building block for skin,bones,tendons,ligaments,and other connective tissues. It provides structural support, strength, and elasticity. As we age, our bodies naturally produce less collagen, leading to common signs of aging like wrinkles, joint pain, and decreased skin hydration. According to the National Institutes of Health, collagen production declines with age and can be influenced by factors like sun exposure and diet.
Types of Collagen supplements
There are two main forms of collagen you’re likely to see for sale: oral collagen products like collagen powders and topical products, like creams and ointments.
Oral Collagen Supplements
Collagen powders have become a popular addition to drinks like coffee, protein shakes, and smoothies. If you don’t like the taste of collagen, or you prefer the convenience of being able to take collagen supplements on the move without the need to mix them into a drink, manny manufacturers sell capsules containing collagen powder.
Collagen capsules have the same ingredients and benefits as collagen powder supplements,as the powder contained inside them is the same as you woudl use to mix with liquids. Some manufacturers also make “collagen shots,” which are premixed collagen drinks for convenience on the go.
Research suggests that oral collagen supplements, including the type of collagen often found in powders, show promise when it comes to reducing the signs of aging. That said, Deanne Mraz, MD, a board-certified dermatologist at Modern Dermatology in Westport, Connecticut, offers some outlook: “Collagen powder is a protein, and when we ingest it, our body digests it the same as any other protein.”
Topical Collagen Products
Collagen creams and ointments are designed to be applied directly to the skin.The idea is that they can help to replenish collagen levels in the epidermis, improving skin elasticity and reducing the appearance of wrinkles. However, collagen molecules are relatively large and may not effectively penetrate the skin barrier. Healthline notes that while topical collagen can provide temporary hydration, its impact on long-term collagen production is limited.
Potential benefits of Collagen Supplements
While more research is needed, several studies suggest potential benefits of collagen supplementation:
