Collagen Benefits in Perimenopause: Skin, Joints, and Beyond
Collagen production drops sharply in perimenopause. Learn what the evidence says about collagen supplements for skin, joints, and bone health.
Why Collagen Declines in Perimenopause
Collagen is the most abundant protein in the human body, forming the structural scaffold of skin, tendons, ligaments, cartilage, and bone. Oestrogen plays an important role in stimulating collagen synthesis and slowing its breakdown. As oestrogen levels decline during perimenopause, collagen production drops significantly, with some research suggesting that women lose around 30 percent of their skin collagen in the first five years after menopause. The effects show up as thinner skin, increased wrinkling, reduced elasticity, slower wound healing, and changes in joint comfort and bone density. This is not merely a cosmetic issue; collagen loss affects structural integrity throughout the body.
Collagen and Skin Changes
Skin changes are often among the first physical signs women notice during perimenopause, and collagen loss is the primary driver. The skin becomes drier, thinner, and less supple. Fine lines deepen and new ones appear, particularly around the eyes and mouth. The skin may feel more fragile and take longer to heal from minor cuts or irritation. Collagen supplements, particularly hydrolysed collagen peptides taken orally, have been studied for their effect on skin hydration and elasticity. Several randomised controlled trials have found improvements in these measures after 8 to 12 weeks of daily use, with doses of 2.5 to 10 grams appearing effective. Results vary between individuals, but the research base is more robust than for many beauty supplements.
Collagen and Joint Health
Type II collagen is the primary structural protein in cartilage, the cushioning tissue between joints. As collagen production declines and cartilage becomes more vulnerable to wear, joint stiffness and discomfort can increase. This overlaps with the joint pain many women experience during perimenopause, where declining oestrogen also reduces the lubrication of joint linings. Undenatured type II collagen, taken in small doses (10 to 40 mg), works through an immune-mediated mechanism and has been studied specifically for joint comfort. Hydrolysed collagen peptides at higher doses have also shown benefit for joint pain in athletes and people with osteoarthritis in clinical trials.
Collagen and Bone Density
Bone is approximately one-third collagen by weight, providing the flexible matrix into which calcium and other minerals are deposited. Without an adequate collagen framework, bones become brittle regardless of calcium intake. Some studies in postmenopausal women have found that specific collagen peptide supplements, when combined with calcium and vitamin D, produced greater improvements in bone mineral density than calcium and vitamin D alone over a 12-month period. While more large-scale research is needed, the mechanism is plausible and the safety profile of collagen supplementation is good. It is best understood as a complementary strategy rather than a replacement for calcium, vitamin D, and weight-bearing exercise.
What to Look for in a Collagen Supplement
Collagen supplements come in several forms: powders, capsules, liquids, and gummies. Hydrolysed collagen peptides in powder form are the most studied and are easy to add to drinks, smoothies, or hot foods. Marine collagen (from fish skin) and bovine collagen (from cattle hide) are the two most common sources in supplements. Marine collagen peptides are generally smaller in molecular size, which may improve absorption slightly. Vegan collagen does not exist in supplement form, as collagen is an animal protein. Some vegan products contain collagen-boosting precursors such as vitamin C, proline, and glycine, but these work differently from actual collagen peptides.
Supporting Collagen Production Through Diet
The body makes collagen from amino acids, primarily glycine, proline, and hydroxyproline, combined with vitamin C as a necessary co-factor. Eating protein-rich foods, particularly those containing these amino acids, supports the body's own collagen synthesis. Bone broth is a traditional source, as simmering bones for extended periods extracts collagen into the liquid. Meat and fish provide the relevant amino acids in abundance. Vitamin C from citrus fruit, berries, bell peppers, kiwi, and broccoli is essential because without it the collagen molecule cannot form its characteristic triple helix structure. Smoking, high alcohol consumption, and excess sugar all accelerate collagen breakdown and counteract the benefits of supplementation.
Realistic Expectations and How to Assess Progress
Collagen supplements are not a rapid fix, and results take time. For skin changes, most studies show meaningful improvements after 8 to 12 weeks of consistent daily use. For joint changes, a similar timeframe applies. The benefits plateau rather than continuing to increase indefinitely, so ongoing use at a maintenance dose is typically the strategy for continued effect. Collagen supplements are generally very safe, though people with fish or shellfish allergies should avoid marine-derived products and choose bovine options instead. Tracking skin, joint, and energy-related symptoms over time helps you evaluate whether supplementation is contributing to improvements, especially when making several changes at once.
