How Much Collagen Should I Take Per Day?

If you’ve ever wondered, “how much collagen per day should I take?” or “how many mg of collagen is right for women?”, you’re not alone. As collagen supplements continue to dominate the wellness space, understanding the optimal dosage is essential for seeing real results.

So, how much collagen per day in mg is ideal? 

Most clinical studies that demonstrate visible improvements in skin, joints, and overall health use doses of 10,000mg (10g) of hydrolysed collagen peptides per day. This is the same high-potency dose found in Rejuvenated’s award-winning Collagen Shots.

 Let’s break down the research and why this dosage matters.

Why 10,000mg Collagen Is the Clinically Studied Dose

Numerous peer-reviewed studies have tested collagen in varying amounts, but 10,000mg per day has consistently shown the most impactful benefits.

Skin Health & Elasticity

 A study published in Skin Pharmacology and Physiology (2014) found that 10g of collagen peptides daily significantly improved skin elasticity and hydration in women aged 35–55 after just 4 weeks.

 Anti-Ageing & Wrinkle Reduction

Research in The Journal of Cosmetic Dermatology (2015) observed reduced wrinkle depth and increased collagen density with daily 10,000mg supplementation.

 “Oral supplementation with specific collagen peptides led to a statistically significant reduction of eye wrinkle volume in comparison to the placebo group.

“After 4 weeks of treatment, skin elasticity in both collagen groups showed a statistically significant improvement in comparison to the placebo group.”

Improved Hydration & Radiance

In a clinical study commissioned by Rejuvenated in 2024, 93% of participants taking 10,000mg of hydrolysed marine collagen daily reported improved skin elasticity, and 86% reported better hydration, texture, and radiance.

How Much Collagen Per Day for a Woman in mg?

While collagen is beneficial for everyone, women over 30 typically begin to experience a natural decline in collagen production – around 1% per year. This can accelerate during perimenopause and menopause.

That’s why a daily intake of 10,000mg is especially effective for women aiming to support:

• Firmer, plumper skin
• Joint and bone health
• Hair strength and nail growth
• Hormonal resilience during ageing

Lower doses, such as 2,500mg or 5,000mg, may offer some benefit, but the clinical outcomes are generally less noticeable and take longer to show.

Rejuvenated Collagen Shots deliver the full 10,000mg dose in a delicious, bioavailable format, supported by vitamin C, hyaluronic acid, and antioxidants to boost collagen synthesis even further.

The Bottom Line

How much collagen should I take?

For visible, clinically-backed results, 10,000mg (10g) per day of hydrolysed marine collagen is the gold standard - especially for women.

Whether you’re looking to improve skin elasticity, reduce the signs of ageing, or support hormonal skin changes, a consistent, daily dose is key.
