By age 60, the body's natural collagen production is dramatically lower, impacting joints, bones, and skin. So, is it worth taking collagen in your 70s? While not a fountain of youth, supplements can provide valuable building blocks to support connective tissues and overall vitality.
What is Collagen and Why it Declines with Age?
Collagen is the most abundant protein in the human body, providing structural support to connective tissues like skin, bones, muscles, tendons, and cartilage. After age 25, natural collagen production slows by about 1-2% annually. For individuals in their 70s, this decline is significant, leading to common signs of aging such as reduced joint cushioning, slower wound healing, weaker bones, and wrinkles. This natural decrease in collagen is a primary reason why many seniors experience aches, stiffness, and reduced mobility. Supplementing with hydrolyzed collagen peptides can provide the body with the necessary amino acids to help combat this age-related loss.
Potential Benefits of Collagen for Seniors
Enhanced Joint Health
For older adults experiencing joint pain or osteoarthritis, collagen supplements offer a promising, low-risk option. Studies have shown that supplementation can help reduce joint pain, enhance mobility, and support cartilage regeneration. A review of 60 scientific studies found that collagen supplements may help reduce and prevent joint pain and bone density loss, offering hope for increased comfort and mobility. For individuals with knee osteoarthritis, collagen supplements might act as a mild pain reliever and improve joint function, though results may take 3-5 months of consistent use.
Improved Bone Density
Bone is rich in collagen, which forms the structural matrix upon which mineralization occurs. The age-related decline in collagen content can make bones more brittle and increase fracture risk. Research involving postmenopausal women with low bone mineral density (BMD) who took 5g of collagen peptides daily for one year showed significant improvement in their BMD. This suggests that collagen supplementation can aid in slowing bone loss and potentially improving bone formation. Specific bioactive collagen peptides have also shown promising results in increasing BMD over four years, offering a potential therapeutic approach for osteoporosis.
Enhanced Skin Health
Visible signs of aging, such as wrinkles and sagging skin, are directly linked to the loss of collagen and skin elasticity. Clinical studies have found that oral collagen supplements can significantly improve skin hydration, elasticity, and reduce wrinkles. The effects are often observed after 8 weeks or more of consistent supplementation. While not a permanent solution, continuous intake is key to maintaining these cosmetic benefits.

How to Choose a Quality Collagen Supplement
- Look for Hydrolyzed Collagen: Also known as collagen peptides, this form is broken down into smaller molecules, making it easier for the body to absorb and utilize. The molecule size (measured in Daltons) should be low (e.g., 3,000 Da or less) for optimal digestion.
- Seek Third-Party Certification: Supplements are not strictly regulated by the FDA. Look for certification from organizations like NSF or USP to ensure the product has been tested for purity, potency, and quality.
- Check for Multiple Collagen Types: Products containing a multi-collagen blend (e.g., Types I, II, III) can provide broader benefits for different bodily tissues.
- Consider the Source: Choose supplements sourced from clean, ethically raised animals (e.g., grass-fed bovine, wild-caught fish) to ensure a high-quality product.
Important Considerations and Potential Risks
While generally safe, it's crucial for seniors to consult a healthcare provider before starting any new supplement. Possible side effects are typically mild and can include:
- Gastrointestinal issues like bloating or stomach upset, especially with non-hydrolyzed forms.
- Rare allergic reactions or histamine sensitivity.
- Cost can be a factor, as quality supplements may be expensive.

Integrating Collagen into a Senior's Diet
Beyond supplements, including collagen-rich foods can support your body's natural production. Great sources include bone broth, fish, chicken, and egg whites. You can also boost your body's ability to produce collagen by consuming foods rich in vitamin C, zinc, and copper.
- Smoothies: Easily mix tasteless collagen powder into your morning smoothie.
- Coffee or Tea: Add a scoop of collagen powder to your hot beverage; it dissolves easily.
- Soups and Stews: Stir powdered collagen into soups and stews for an easy protein boost.
Conclusion: Making an Informed Choice
For those in their 70s, the decision of whether to take collagen depends on individual health goals and lifestyle. The scientific evidence suggests that supplementing with collagen peptides is a low-risk strategy with potential benefits for joint comfort, bone health, and skin hydration, all of which contribute to a higher quality of life. However, it is not a cure-all, and consistency is key to seeing results. Always have a conversation with your primary care physician to determine the best approach for your specific health needs.
