Vital Proteins Collagen Peptides (unflavored)
by Vital Proteins · The reviewed product
20 g hydrolyzed bovine type I & III per serving. The category leader, single ingredient, dissolves clean.
The label audit, line by line. Dose: 20 g of hydrolyzed bovine type I and III per two-scoop serving, comfortably above every dose used in the published trials (2.5 to 15 g), so the science ceiling is covered. Ingredients: one, which we credit; no proprietary blends, no sweeteners in the unflavored tub, dissolves clean in hot or cold liquid. Sourcing: grass-fed, pasture-raised bovine hide, with brand-run heavy-metal testing but no NSF or Informed Sport certification, the one real gap on the spec sheet. The skin, hair and nail claims on the front of the tub lean on the category's trial literature rather than trials of this specific product, which is standard practice and worth knowing. Price sits at roughly $1.57 per serving, a premium over equally clean competitors. Net: the category benchmark, honestly labeled, slightly overpriced for what is chemically a commodity.
Hydrolyzed collagen is the rare supplement-aisle product with randomized human trials behind specific claims: a 2021 meta-analysis of 19 RCTs found improved skin hydration and elasticity after roughly 90 days, and a 24-week randomized trial reported less activity-related joint pain at 10 g per day. The effects are modest, many trials are industry-funded, and the hair, gut and weight claims on most tubs outrun the data. We grade the full evidence file in our collagen peptides review; the short version is that skin and active-joint endpoints are earned, the rest is marketing.
The published trials used 2.5 to 10 g daily for skin endpoints, 10 g for joint comfort, and 15 g in the muscle protocols paired with resistance training, taken for 8 to 24 weeks; nothing in the literature supports week-one effects. Timing is unstudied except for one pre-exercise protocol, so consistency beats clock-watching, and hot coffee does not degrade the peptides. Vitamin C is a genuine cofactor in collagen synthesis, so taking your scoop with a meal that includes some costs nothing. This is reported from the trials, not a prescription.
