Collagen Supplements and Menopause: Is There Any Evidence?

What Happens to Collagen at Menopause?

Collagen is the structural framework for skin, joints, bones, and connective tissue. From our mid-20s, collagen levels naturally decline, but this process accelerates during and after menopause. Studies suggest that women can lose up to 30% of skin collagen in the first five years post-menopause, largely due to falling oestrogen. This loss contributes to:

• Thinner, less elastic skin
• Fine lines and wrinkles
• Dryness
• Reduced bone density and joint support
  
  

Given these changes, it’s explains why all those social media adverts seemed to be aimed at you.

What Do Collagen Supplements Actually Contain?

Most supplements use hydrolysed collagen peptides—tiny fragments of collagen derived from animal sources (bovine, porcine, or marine). These are broken down so they’re easier to absorb in the digestive tract.

The Evidence So Far:

Skin Health

• A 2019 meta-analysis of 11 randomised controlled trials (RCTs) involving over 800 participants found that oral collagen peptides improved skin elasticity, hydration, and dermal collagen density compared with placebo.
• Some studies specifically in postmenopausal women show modest improvements in wrinkle depth and skin thickness after 8–12 weeks of daily supplementation.
  
  

Bone Health

• Early studies suggest collagen peptides may support bone metabolism. In a 2018 RCT of postmenopausal women with low bone density, those taking collagen peptides had increased bone mineral density after 12 months compared to placebo.
• However, this research is still in its infancy and needs confirmation in larger, long-term studies.
  
  

Joint Health

• Several trials (in both men and women) suggest collagen may reduce joint pain and stiffness, particularly in those with osteoarthritis. This could be relevant for menopausal women who often report new or worsening joint symptoms.
  
  

Hair and Nails

• Evidence is weaker here. A handful of small studies suggest collagen might reduce nail brittleness and improve hair thickness, but findings are inconsistent and not specific to menopause.
  
  

Limitations of the Evidence

• Many studies are small, short-term, and often industry-funded.
• There’s no standard dose, but most trials use 2.5–10g of hydrolysed collagen daily.
• Benefits, when seen, are modest rather than transformative.
• It’s difficult to know whether improvements are due to collagen itself, or simply better protein intake.
  
  

So, Should Menopausal Women Take Collagen?

At present, the science suggests that collagen supplements may provide some benefit for skin hydration and elasticity, and possibly for bone and joint health in women around menopause. The effects are usually small, but they may be worthwhile as part of a broader self-care routine that includes:

• A protein-rich, balanced diet with omega 3
• Weight-bearing exercise
• Sun protection for skin health
• Adequate vitamin D and calcium for bones (calcium from food is better than from supplements)
• Considering HRT or other prescribed treatments where appropriate
