Collagen: what the evidence says

Collagen peptides are the most researched skin supplement, but the picture is mixed. A 2021 meta-analysis of 19 trials reported better skin hydration, elasticity and wrinkle scores after about 90 days of hydrolysed collagen. A 2025 meta-analysis of 23 trials, co-authored at Monash University, found that the positive results came from industry-funded and lower-quality studies, while independent and high-quality studies showed no significant effect. Collagen is also an incomplete protein because it lacks the amino acid tryptophan, so it does not replace a regular protein powder.

Vitamins and minerals

  • Zinc helps the body make proteins and DNA and helps wounds heal. The adult upper limit is 40 mg a day from all sources, and long-term high intakes can lower copper levels and immunity.
  • Vitamin A is needed for normal vision, immune function and growth. The upper limit for preformed vitamin A is 3,000 mcg a day for adults, and high doses in pregnancy can cause birth defects.
  • Omega-3 oils and vitamin E also appear in this range; check the dose per capsule and any multivitamin you already take.

How to compare products

  • Collagen per serve. Research has used about 2.5 to 15 g of collagen peptides a day. Check grams per scoop and whether it is hydrolysed.
  • Source. Collagen may come from bovine, marine or mixed sources, which matters for allergies and dietary choices.
  • Dose versus upper limits. Some zinc and vitamin A products sit at or above the upper limit per capsule.
  • Oral or topical. The Ordinary Niacinamide Zinc Serum in this collection is applied to skin, not swallowed.

Safety

Pregnant or breastfeeding women should not take high-dose preformed vitamin A supplements. Vitamin A supplements can also interact with some prescription skin medicines made from vitamin A. Separate zinc from quinolone or tetracycline antibiotics by at least 2 hours before or 4 to 6 hours after. No supplement replaces daily sun protection.

Skin Health: questions and answers

Does collagen powder actually improve skin?
The evidence is mixed. A 2021 meta-analysis of 19 trials reported better hydration, elasticity and wrinkle scores after around 90 days. A larger 2025 meta-analysis of 23 trials found those benefits came from industry-funded and lower-quality studies, while independent, high-quality trials showed no significant effect. If you try collagen, keep expectations modest and give it a few months.
How much collagen should I take a day?
Follow the label. Studies on collagen peptides have generally used about 2.5 to 15 g a day. Because collagen lacks the amino acid tryptophan, it is classed as an incomplete protein, so count it as a supplement rather than a replacement for protein foods or a regular protein powder.
Can I take zinc every day for my skin?
Zinc is needed to make proteins and DNA and helps wounds heal, but more is not better. The US National Institutes of Health sets the adult upper limit at 40 mg a day from all sources, and long-term high intakes can lower copper levels and immunity. Some zinc capsules contain 50 mg, so check with your doctor before taking them long term.
Is vitamin A safe to take during pregnancy?
High-dose preformed vitamin A supplements are not recommended during pregnancy or breastfeeding. The US National Institutes of Health warns they can cause birth defects, and sets the adult upper limit for preformed vitamin A at 3,000 mcg a day. Beta-carotene from plants does not have the same upper limit. Talk to your doctor or midwife before taking any vitamin A product.
How long does collagen take to help skin?
Allow at least two to three months. Most skin trials on hydrolysed collagen have run for several weeks to a few months, and a 2021 meta-analysis reported changes in hydration and elasticity after around 90 days. Results vary: a 2025 meta-analysis found that independent, high-quality trials showed no significant effect. If you want to try it, take a consistent daily serve of a hydrolysed collagen such as Rapid Total Collagen, Rule One's R1 Collagen or Cyborg Sport Collagen Pro, keep using sunscreen, and judge it on how your skin looks after a few months.
Do you stock hyaluronic acid supplements?
Yes. This range includes Piping Rock Hyaluronic Acid, with 100 mg per serving in 60 quick-release capsules. Hyaluronic acid occurs naturally in skin, connective tissue and joints, where it helps hold water. A few small trials of oral hyaluronic acid have reported better skin moisture, but the evidence is limited, so think of it as an optional extra. It also appears in joint blends such as California Gold Nutrition Glucosamine, Chondroitin, MSM plus Hyaluronic Acid, while topical serums that contain it work on the skin surface instead.
