Collagen for healthy tissues
Whenever I go to the grocery store, I see collagen prominently featured on labels of everything from drinks and protein powders to snack bars. Fueled in part by celebrity endorsements promising eternal youth, collagen consumption has surged. However, not everyone understands what collagen is or how it actually works.
What is Collagen?
Collagen is the most abundant structural protein in the human body, accounting for approximately 30% of total protein. It plays a crucial role in maintaining the integrity and shape of the skin, connective tissues, tendons, bones, cartilage, and blood vessel walls. Although the body produces 28 different types of collagen, the most common structure consists of three amino acids—glycine, proline, and hydroxyproline—that form a triple-helix spiral known as the collagen helix.
Beyond providing structure, collagen also facilitates cellular movement in response to stimuli, promoting tissue formation and regeneration as needed. Fibroblasts, the connective tissue cells responsible for collagen production, play a key role in wound healing, scar formation, and bone health. As we age, fibroblasts deteriorate, leading to reduced collagen production. This decline results in brittle hair and nails, reduced bone density, increased susceptibility to fractures, and slower healing times.
As we age collagen starts to deplete and the skin becomes less plump and elastic.
How to Support Collagen Production Naturally
To support collagen production, consuming foods rich in amino acids—particularly glycine, proline, and lysine—is essential. These include bone broth, fish, and meat. For vegetarians, options such as eggs, wheat, soy, and other protein-rich foods can help supply the necessary building blocks. The body naturally synthesizes collagen by breaking down these amino acids during digestion and distributing them via the bloodstream to areas in need of repair and maintenance.
While topical collagen products may be more of a marketing gimmick, collagen supplements and powders can be effective. These typically contain hydrolyzed collagen or collagen peptides—broken-down collagen derived from bones and cartilage, which are byproducts of the fish and meat industry that would otherwise go to waste.
The Role of Hyaluronic Acid and Elastin
Collagen doesn’t work alone. Two key components that enhance the mechanical properties of connective tissues are hyaluronic acid and elastin.
Elastin is a protein that works alongside collagen to provide elasticity to tissues. It allows the skin to snap back when pinched and helps lung tissues expand and contract during breathing. The gradual loss of both collagen (which provides structure) and elastin (which provides flexibility) leads to sagging skin over time.
A simple way to test skin elasticity is the pinch test: Pinch the skin on your hand for a few seconds and observe how long it takes to return to normal. If it takes more than five seconds and you’ve been drinking plenty of water, your elastin levels may be low.
Hyaluronic acid, a carbohydrate molecule, works with collagen to retain moisture, keeping skin hydrated and plump while reducing the appearance of fine lines and wrinkles. Many topical skincare products containing collagen and hyaluronic acid offer an instant refreshing effect, although their long-term effectiveness is debated.
Choosing the Right Collagen Supplement
Incorporating a collagen supplement into your routine can be beneficial, but it's important to choose the right one for your needs. Collagen supplements typically contain one or a combination of the first three types of collagen.
Type I: Best for enhancing skin elasticity and hydration.
Type II: Ideal for improving joint flexibility.
Type III: Supports muscle recovery and overall skin health.
For optimal absorption, look for products that list prolyl-hydroxyproline or hydroxyprolylglycine in the ingredients. These dipeptides are more easily absorbed by the body and contribute to improved skin hydration and elasticity.
If you're vegan, there’s great news! Advances in biomimetics—the science of replicating natural phenomena—have led to the development of vegan collagen alternatives, often called collagen boosters. These plant-based options typically contain amino acids, vitamin C, and botanical extracts such as bamboo and soy, which enhance the body's natural ability to produce collagen Type I. Research suggests they can be effective in firming and moisturizing the skin.
As with any supplement, monitor how your body responds. If you experience discomfort, it may not be the right fit for you. Always consult your doctor before adding a new supplement to your regimen, especially if you take medications.
Hydration: The Key to Healthy Skin
Hydration is essential for supple, glowing skin. Be sure to drink plenty of water, and consider adding electrolytes such as Cure Organic Electrolytes, which come in a variety of delicious flavors.
