Collagen Greens for Women Over 40

Why collagen decline accelerates in your forties — and what to do about it

What Happens to Collagen After 40

By the time most women reach 40, they have already lost approximately 20–25% of their peak collagen mass. Production has been declining at roughly 1% per year since the mid-twenties — but the real acceleration happens as oestrogen begins to decline in perimenopause.

Oestrogen plays a direct role in collagen synthesis. Oestrogen receptors are present in skin fibroblasts (the cells that produce collagen), and declining oestrogen in perimenopause and menopause appears to directly reduce collagen production rates. Research suggests women can lose up to 30% of skin collagen in the first five years after menopause.

The visible and physical effects compound: skin loses firmness and develops lines, joints feel stiffer, recovery from activity takes longer, and muscle mass becomes harder to maintain. These are not separate, unrelated changes — they are all partly downstream of the same structural protein decline.

What Collagen Greens Addresses for Women Over 40

Collagen Greens provides 4g of hydrolysed bovine collagen (Types I & III) per daily scoop — the types most directly relevant to skin firmness, elasticity, tendon strength, and joint support. Clinical research at similar doses consistently shows improvements in skin elasticity within 4–8 weeks and reductions in exercise-related joint discomfort at 8–24 weeks.

The creatine component is often overlooked by women in this age group, but it is arguably as important as the collagen. After 40, muscle mass naturally declines (a process called sarcopenia). Creatine — at 4g per serving — supports muscle cell energy production, reduces fatigue, and helps maintain lean mass when combined with regular activity. Multiple meta-analyses now show creatine is as beneficial for women as for men.

The super greens blend contributes antioxidant compounds — particularly from spirulina and chlorella — that help neutralise the oxidative stress that degrades collagen. You are simultaneously replenishing collagen and protecting what remains.

  • Type I & III collagen — targets skin, tendons, ligaments, and bone
  • Creatine — helps preserve muscle mass and supports energy levels
  • Super greens — antioxidant protection for collagen integrity
  • DigeZyme® enzymes — for better nutrient absorption overall

The Evidence for Women Over 40 Specifically

Most collagen skin studies have specifically recruited women aged 35–55, making the evidence base particularly relevant to this demographic. A 2014 RCT in Skin Pharmacology and Physiology (women aged 35–55) found statistically significant improvements in skin elasticity at 8 weeks with as little as 2.5g of collagen peptides daily. Collagen Greens provides 4g.

On the creatine side: a 2021 meta-analysis in Nutrients reviewed 9 studies specifically in women and found creatine supplementation significantly improved upper and lower body strength and lean mass, with effects comparable to those seen in men. The researchers concluded that women should not be discouraged from creatine supplementation and that it may be particularly valuable post-menopause when muscle preservation is critical.

How to Build It Into Your Routine

One scoop (12.6g) mixed into 300ml of cold water, once daily. Morning is most popular — before or with breakfast — as it establishes the habit and starts the day with a foundational nutritional base. It mixes cleanly with a simple shake or stir; no blender required.

Results build over time. Most women in this age group report noticing improved energy within the first two weeks. Skin improvements typically become noticeable from week four to eight. Joint comfort improvements tend to follow consistent use over 8–12 weeks. Patience and consistency are the two non-negotiable requirements.

Frequently Asked Questions

Yes — creatine has an excellent safety profile across all demographics and is among the most studied supplements in the world. There is no evidence of harm in healthy adults of any age. If you have kidney disease or are on medication, consult your GP first, as a general precaution with any supplement. The dose in Collagen Greens (4g per serving) is well within the range used safely in clinical research.

Collagen supplementation is well-evidenced to improve skin elasticity and hydration — both of which contribute to a more firm, plump appearance. Clinical studies show measurable improvements in skin elasticity within 8 weeks. That said, significant structural sagging involves factors beyond collagen supplementation, including skin laxity and volume loss that cannot be fully addressed by supplements alone. Managing expectations: you will likely see a real but modest improvement, not a dramatic transformation.

There is no known interaction between collagen peptides, creatine, or the greens blend in Collagen Greens and HRT medications. That said, always inform your prescribing doctor of any new supplements when you are on prescription medication.

Energy improvements are often reported within 1–2 weeks (particularly from the creatine component). Skin changes typically become noticeable from weeks 4–8. Joint comfort improvements tend to follow consistent use over 8–12 weeks. Individual results vary based on baseline collagen levels, sun damage history, and other lifestyle factors.
