Supplement
Collagen Peptides
Collagen peptides show solid evidence for improving skin hydration and elasticity, addressing one of the most noticeable effects of estrogen decline. Some studies suggest benefits for joint comfort and bone density, though these outcomes need more research in menopausal women specifically. While we cannot fully replace the collagen we're losing, supplementing may help slow some of the visible and felt changes during this transition.

Overall: Mixed evidence
Randomised controlled trials
Multiple RCTs show consistent skin hydration and elasticity improvements, while joint and bone benefits show promise but with smaller, shorter studies.
Population studies consistently link higher collagen intake with better skin aging markers and fewer joint complaints.
Meta-analyses confirm skin benefits from collagen supplementation with moderate to strong effect sizes.
Menopause-specific trials
Very few studies have specifically examined collagen peptides in menopausal women, leaving this population understudied.
What we do not know
Most studies have been conducted in younger adults or mixed age groups rather than specifically in perimenopausal and postmenopausal women. The optimal dosing for menopause-related collagen loss has not been established through direct comparison studies. We don't know if marine-derived collagen peptides work differently than bovine sources for menopausal symptoms. Long-term safety data beyond 12 months of use is limited. The interaction between collagen supplementation and hormone therapy has not been studied.
How it is used
Common dose range
10-15g daily
Notes on dosing
Marine or bovine collagen peptides are well-absorbed. Take with vitamin C.
Get it from food first
Food sources are better absorbed than most supplements and come with co-factors that support the same pathways. If you eat two or three of these consistently, you may not need a supplement at all.
bone broth
1 cup
highest natural source when simmered 12+ hours
chicken skin
1 serving
significant collagen when cooked with bones
fish with skin
4 oz
salmon, sardines provide marine collagen
egg whites
3 large
contain collagen precursor amino acids
Mediterranean diet
provides vitamin C, antioxidants, and anti-inflammatory compounds that support collagen synthesis
traditional cooking methods
slow cooking with bones and connective tissue maximizes natural collagen extraction
What depletes Collagen Peptides
High sugar intake accelerates collagen breakdown through glycation. Excessive alcohol consumption interferes with collagen synthesis. Chronic stress elevates cortisol, which breaks down existing collagen. UV exposure without protection degrades skin collagen. Smoking significantly accelerates collagen loss throughout the body.
Interactions and cautions
No significant interactions noted at recommended doses.
Rose bottom line
"Your body is working hard through this transition, and while collagen peptides won't turn back time, they offer reasonable support for skin and possibly joints with minimal risk. The evidence is strongest for skin benefits, which many women notice first as estrogen declines. If you're looking for comprehensive support, pair this with vitamin C-rich foods and strength training, which both support your body's natural collagen production."
