Liquid Collagen Skin Health

The double dose

5000mg of hydrolysed marine collagen per sachet, more than one and a half times a standard 3g powder serve, already in solution so the peptides need no mixing and nothing to dissolve. Hydrolysed peptides are absorbed through the gut and signal fibroblasts in the skin to produce new collagen; the dose is what sets this apart from the powders.

The supporting bench

Liposomal vitamin C, the form wrapped in a lipid shell for better uptake, is a cofactor the body needs to build collagen at all. B-Blend4 is Vida Glow's four-part antioxidant complex against the free-radical damage behind premature ageing, and biotin covers hair and nails.

What the brand reports

With consistent daily use, Vida Glow reports an 18% increase in skin firmness and an 11% reduction in crow's feet at eight weeks, and 96% of participants seeing a reduction in wrinkles at twelve. Brand-run studies, as is the norm for ingestibles.

The fit

The highest collagen dose in the range per serve. Liquid Collagen Skin + Energy is the morning version with ginseng and green tea; this one has no caffeine and can be taken any time.

Skin that wants the strongest daily collagen dose without a powder; hair and nails that need support alongside; and anyone who takes collagen on the move, since it is torn open and drunk on the spot.

Worth knowing

Contains fish: not for a fish or seafood allergy, and not vegetarian or vegan. Pregnant or breastfeeding, check with your practitioner before starting any supplement. Results in the brand's studies appear from eight weeks of daily use.

Tear and drink straight from the sachet, one to two a day, any time. Keep it cool and shake before opening.

Fifteen sachets is one to two weeks; the results depend on taking it daily for at least eight.

Use alongside

Take it as your only collagen for the day, or alternate with Pro Collagen+ or the Original powder. On the skin, Liquid Peptides Advanced MP and a retinoid do the topical collagen work, C E Ferulic and SPF protect it.
