2.5g a day, 8 weeks: measurably better skin elasticity in 69 women.
5g a day + training: Achilles tendon grew 11% vs 4.7% on placebo. Fewer ankle re-injuries in athletes.
10g a day, 24 weeks: less activity-related joint pain in 147 athletes. Knee cartilage improved on MRI.
15g a day + training: +4.2kg fat-free mass and bigger strength gains than training alone.
20g a day around hard sessions: jump performance back faster at 48h, soreness trending lower. One KUDU shot, two sips.

Before you ask
Because each shot carries 20,000mg of collagen, not 5,000 to 11,000mg, at a similar price per sachet. On subscription a 14-shot box is Β£27.96, which works out at 10p per 1,000mg. The UK average for liquid collagen is 31.1p.
It is hydrolysed collagen, the form used in the skin, nail and joint studies. Many beauty sachets use marine collagen; KUDU uses grass-fed bovine collagen, types I and III, with no fishy aftertaste. Informed Sport certified, made in the UK.
The skin and nail studies used 2,500mg a day; the tendon, joint and muscle studies used 5,000 to 15,000mg. One KUDU shot is 20,000mg, plus 20g of protein, which contributes to the growth and maintenance of muscle mass.
Yes to both. The protein is hydrolysed bovine collagen; there is no whey, casein or milk, and it is gluten-free. It is not vegan.
Thicker than water, like a fruit gel, and gone in two sips. Most reviewers prefer it cold from the fridge.
