Overview
Vital Proteins is the category's most recognisable name - a grass-fed bovine hydrolysed collagen powder sold globally. It claims to support skin, hair, nails, and joints.
Who it may suit
People who want a clean, high-dose hydrolysed collagen with third-party testing and don't mind mixing a powder into coffee, water, or smoothies. Good fit for skin and general wellness goals where dose matters more than collagen type.
Less suited to: Pescatarians, vegans, and anyone wanting a flavoured or capsule format. People specifically targeting joints will get more from a UC-II type II product at a much lower dose.
Ingredient and dose breakdown
20g of hydrolysed bovine collagen peptides per serving - at the top end of the 5–15g evidence-backed range for skin. No additives, sweeteners, or fillers in the unflavoured version. Bovine source means type I and III collagen, which is appropriate for skin, hair, nails, and gut goals.
What stands out
The dose is genuinely generous - many competitors sit at 10g and charge similar prices. Informed Sport certification means independent batch testing for banned substances, which matters for athletes.
What to watch
Flavoured versions add stevia and natural flavours that some users dislike. The brand's marketing leans heavily on celebrity and influencer use, which doesn't change the product but can inflate price expectations.
Evidence summary
Hydrolysed bovine collagen at 10–20g daily has multiple randomised trials showing modest improvements in skin elasticity and hydration over 8–12 weeks. Most of these studies are funded by collagen manufacturers, which doesn't invalidate them but is worth knowing. Joint claims are weaker than the brand suggests for this type.
Timeline expectation
Studies consistently show measurable changes at the 8 week mark, with most reporting peak effect around 12 weeks. Don't expect results in two weeks - anyone selling that is overpromising.
