Collagen supplements in menopause: skin, hair, joints and the evidence

Name: Collagen supplements in menopause: skin, hair, joints and the evidence
Creator: MenoWoman

Collagen is the main structural protein in skin, bone and joints, and the body makes less of it with age. Collagen supplements are popular, but independent research has not shown they reliably improve skin aging.

See a doctor if you have sudden hair loss, skin changes that worry you, or joint pain with swelling, redness or stiffness, as these need a proper diagnosis.

What it is

Collagen is a protein found in bone, skin, tendons, ligaments and blood vessels. It makes up at least 30% of the body's protein, and levels fall with age.¹

Supplements usually come from cows, fish or chicken. They are sold as powders, capsules, drinks and gummies.¹

Digestion breaks collagen down into amino acids, the building blocks of protein. So there is no guarantee it reaches the skin or joints, as labels suggest.¹

What the research shows

Earlier reviews of collagen for skin looked positive. A 2025 analysis in The American Journal of Medicine pooled 23 trials with 1,474 people.²

At first, the pooled results showed better skin moisture, elasticity and wrinkles. But trials funded by companies showed benefits, while trials without industry funding did not. When only higher-quality studies were counted, there was no clear effect.²

Industry groups disputed this. They said the term collagen covers many different products, and that some trials were labeled wrongly as independent.²

A separate critique by a statistician and a dermatologist re-examined two earlier reviews. They found most included trials had industry links. After fixing errors, they found no link between collagen dose and better skin moisture or elasticity.³

For hair, nails and joints, Mayo Clinic says benefits are not established. It notes there are few large, long-term trials.¹

Safety and who should be careful

Collagen is a food protein and is generally thought to be low risk. Because products come from animals or fish, people with fish allergies or certain diets should check the source.¹

Some products include other ingredients, such as biotin, vitamins or herbs. These can carry their own risks. For example, high-dose biotin can distort some blood tests, including thyroid and heart tests.⁴ See biotin.

A doctor or pharmacist can check whether it interacts with any medicines or other supplements you take.

Other ways to support collagen

The body makes collagen from protein in food. Mayo Clinic suggests a protein-rich diet, including dairy, beans, tofu, fish, meat and gelatin.¹

Collagen-making also needs vitamin C, zinc and copper. Smoking, too much sugar and sun damage can break down collagen in the skin.¹

Availability and the bottom line

Collagen is sold widely as a food supplement, with no prescription needed. In the US, supplements are not approved by the FDA before sale, so quality and content vary between brands.

Collagen supplements are widely marketed, but the research behind them is mostly small and often industry-funded. Independent and higher-quality studies have not shown clear benefits for skin aging.^2,3

Proven ways to protect skin include sun protection and not smoking.¹ A dermatologist can advise on treatments with stronger evidence for skin aging and dryness.
