Sports Research Collagen Peptides (Bovine) Review

Same brand, different source — and it's an important distinction. This is the BOVINE (beef-hide) version: grass-fed, pasture-raised type I/III peptides, no fish, Paleo and Keto certified. The marine version (#3) is wild-caught fish-skin type I collagen, pescatarian-friendly, with hyaluronic acid and vitamin C added. Choose bovine (this one) if you want type III alongside type I, no fish note, a Paleo/Keto-certified single-ingredient panel, and no fish-allergy concern. Choose marine (#3) if you specifically want a fish source, slightly smaller peptides, or you're pescatarian. Both are clean, well-tested Sports Research products; the source is the deciding factor.

A clean panel with nothing but grass-fed bovine collagen peptides — no fillers, sweeteners, flavors, or added actives. That appeals to Paleo and Keto buyers and to anyone who wants to know exactly what's in the scoop. The trade-off is that you don't get a built-in vitamin C cofactor the way co-formulated picks (#2, #8) do, so you'll pair your own vitamin C. Single-ingredient is a philosophy choice: maximum label purity and certification-friendliness versus the convenience of an all-in-one beauty scoop. If clean-label is your priority, this is the pick; if you want the cofactor built in, look at #2 or #8.

One scoop is ~11 g, which clears Clark 2008's 10 g athlete-joint dose and sits well above Proksch 2014's 2.5-5 g skin dose — so one scoop covers the joint trial and the skin floor. For the full 10-20 g connective-tissue window, run two scoops (~22 g), which also matches the 20 g the premium tubs advertise. Note that ~11 g per scoop means two scoops uses the 16 oz tub faster than a 10 g-per-scoop tub would. Practically: one scoop for the skin/joint floor, two for the full window, and factor the faster tub turnover into the cost math.

Because it overlaps heavily with both rather than beating either on a single axis. It's a clean, grass-fed, certified bovine peptide — genuinely good — but Vital Proteins (#2) owns the brand-default position and NOW (#5) owns the cost-per-gram crown, and Sports Research bovine sits between them without clearly winning either lane. It lands at #6 not because it's worse in quality but because it's a strong value-positioned alternative in a crowded bovine-peptide field. It's the right pick specifically when you want grass-fed sourcing, Paleo/Keto certifications, and a no-fillers panel at a mid price — that's the niche it owns.

No — it's deliberately single-ingredient, so there's no added vitamin C, and you'll want to pair it with your own C source. Vitamin C is the rate-limiting cofactor for collagen synthesis, so adequate intake matters for results, but adding a cheap separate vitamin C (or just sufficient dietary C) handles it trivially. If you'd specifically rather have the cofactor already in the scoop, the co-formulated picks — Thorne Collagen Plus (#4) or Live Conscious (#8) — build it in, at the cost of the clean single-ingredient panel that's this product's whole appeal.

No — Sports Research bovine peptides are a skin-and-connective-tissue product, not an osteoarthritis treatment. OA responds to undenatured type II collagen (UC-II) at 40 mg/day via immune tolerance; Lugo 2016 (PMID 26822714) showed that form beat glucosamine + chondroitin on knee-OA WOMAC over 180 days. The type I/III peptides here can support general/activity-related joint comfort (the Clark 2008 lever) but won't replicate the OA mechanism. For diagnosed osteoarthritis, buy NOW UC-II Type II Collagen (#1).

[1] Proksch 2014 PMID 23949208 — Oral supplementation of specific collagen peptides has beneficial effects on human skin physiology: a double-blind, placebo-controlled study. 69 women, 8 weeks: 2.5-5 g/day collagen peptides improved skin elasticity versus placebo, persisting after dosing. Sports Research's type I/III bovine peptides are this exact form, delivered above the trial dose at a single scoop.

[2] Clark 2008 PMID 18416885 — 24-Week study on the use of collagen hydrolysate as a dietary supplement in athletes with activity-related joint pain. 147 athletes, 24 weeks: 10 g/day collagen hydrolysate reduced activity-related joint pain versus placebo. One ~11 g Sports Research scoop clears this dose — the basis for the general joint-comfort claim, distinct from osteoarthritis (UC-II).

Cited as the contrast — Sports Research bovine peptides are a skin product, not an osteoarthritis treatment; OA buyers should choose UC-II (#6).
