Applied Nutrition Liquid Collagen Skin Revitalization
Ranked #2$24.99

Single-serve liquid tubes delivering hydrolyzed collagen with biotin and silica. The widely sold drugstore liquid format, lower in collagen per serving (about 4 g) than the powders.

Our assessment

Single-serve liquid tubes delivering hydrolyzed collagen with biotin and silica, the most widely distributed drugstore liquid format in the US. The honest caveat is the dose: at around 4 g of collagen per serving, it sits below the 2.5 to 10 g that the published skin trials used, so one serving lands at the low end of the studied range. Biotin and silica are marketing additions without strong standalone human-endpoint evidence. Choose it for the taste and convenience, not for the collagen dose.

What the evidence supports

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.

Use, as reported in the trials

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.
