Goal: Skin & structure

Unflavored collagen for skin, joints, muscle and bone.* Across 35 trials, collagen improved skin hydration, elasticity and the skin barrier, most clearly by about 12 weeks, and across another 19 trials in active adults, collagen with resistance training built more lean mass than training alone.* Cellovi Grass-Fed Collagen Peptides give you 20 g of hydrolyzed bovine collagen, types I and III, in one unflavored scoop that disappears into coffee, smoothies or water.

Key studies

  1. Batool et al., 2026Meta-analysis of 35 trials Better skin hydration and elasticity than placebo, and a stronger skin barrier, with less water lost through the skin. Elasticity was clearest by about 12 weeks.
  2. de Miranda et al., 2021Meta-analysis of 19 trials 19 trials with 1,125 people, mostly women aged 20 to 70. Collagen improved skin hydration and elasticity compared with placebo, after about 90 days.
  3. Pu et al., 2023Meta-analysis of 26 trials 26 trials with 1,721 people. Better skin hydration.
  4. Proksch et al., 2014Randomized, double-blind, placebo-controlled One trial at 2.5 g a day. Skin elasticity improved within 8 weeks.
  5. Bischof et al., 2024Meta-analysis of 19 trials 19 randomized trials with 768 active adults, mostly 15 g a day alongside resistance training. More lean mass than training alone, with moderate certainty.
  6. König et al., 2018Randomized, double-blind, placebo-controlled 131 women after menopause, with lower bone density, took 5 g of specific collagen peptides a day for 12 months. Bone mineral density at the spine and hip rose, while it slipped in the placebo group.
  7. Zdzieblik et al., 2021Randomized, double-blind, placebo-controlled 180 active adults aged 18 to 30 with knee discomfort during sport took 5 g of specific collagen peptides a day for 12 weeks. Knee discomfort during activity fell more than with placebo.

Before you start

Interactions and cautions

Check with your doctor first if you:

  • have a history of kidney stones or kidney disease: large amounts of collagen raise urinary oxalate
  • are pregnant, nursing or under 18

Do not take it if you:

  • have a red-meat or gelatin allergy (alpha-gal)

Not a complete list. Show your pharmacist everything you take, including other supplements. Sources: Mullins et al., 2012; Knight et al., 2006.

Reviews

New, so no reviews yet

Here is what you can check instead. Every claim on this page has an evidence grade and a link to the study behind it. We won’t fill this space with borrowed praise.

We started Cellovi because shopping for supplements meant wading through big promises, hidden doses and claims with no study in sight. So we built the brand we wanted to buy from.

Your reviews come next, and we’ll read every one.
