Collagen Supplements: Science-Backed Anti-Aging Benefits | Dr. Anthony Youn

Collagen Creams vs. Supplements

• 🧴 Collagen creams are ineffective because collagen is a large protein that cannot be absorbed by the skin, acting merely as a fancy moisturizer.
• 💡 Collagen supplements, however, are a different matter and are supported by scientific evidence.

The Science Behind Collagen Supplements

• 🔬 The primary argument against collagen supplements is that the body breaks down large proteins. However, hydrolyzed collagen peptides are specifically designed to be broken down into smaller, absorbable amino acids and peptides.
• ✅ Numerous studies, including a 2021 meta-analysis of over 1,200 people, show statistically significant improvements in skin hydration, fine lines, wrinkles, and elasticity after 90 days of supplementation.
• 🧬 Skin biopsies from participants in clinical trials have also shown thicker collagen and overall skin thickness after collagen supplementation.

Types of Collagen and Their Benefits

• 🌟 There are five types of collagen, but Type 1 (skin, hair, nails), Type 2 (muscles), and Type 3 (joints) are most relevant for supplements.
• 🎯 Choosing a supplement that contains multiple types, like the one Dr. Youn's brand offers, can address various potential concerns.
• 🚫 Types 4 (kidneys) and 5 (placenta) are generally not a focus for dietary supplements.

Factors Contributing to Aging

• 🥓 Advanced Glycation End Products (AGEs) contribute to aging, primarily formed by sugar but also found in high-fat, ultra-processed, and highly heated animal-based foods like bacon and charred meats.
• 📉 While sugar is a major contributor, AGEs can also form from grilling or overcooking foods, leading to charring.
• 🧘 Chronic stress significantly ages the body, visible in changes like those seen in US presidents over their terms. Activities like meditation, yoga, and adequate sleep can help mitigate stress.
• 🧊 Acute stress, like that induced by cold plunges, can be beneficial for anti-aging, contrasting with the detrimental effects of chronic stress from daily life pressures.
