Collagen shots with a working dose: 20,000mg in 63ml
A collagen shot is a small ready-to-drink serving of hydrolysed collagen, and the best collagen shots are the ones that deliver a studied dose without a spoonful of sugar. Most shots sold in the UK are built for the beauty aisle at 5,000 to 10,000mg per bottle. A KUDU shot is a 63ml sachet with 20,000mg of hydrolysed bovine collagen (20g of protein), 0g sugar, 0g fat and 85 calories. That is the top of the range the tendon, joint and recovery studies actually used, in a format you can finish in two sips on the way to training. Not beauty collagen. Performance collagen.

KUDU collagen shot vs a typical beauty collagen shot
| Per shot | KUDU collagen shot | Typical marine beauty shot |
|---|
| Collagen dose | 20,000mg | 5,000–10,000mg |
| Collagen type | Bovine, type I and III | Marine, mainly type I |
| Sugar | 0g | Varies; check the label |
| Cost per 1,000mg | 12.5p one-time | UK liquid-collagen average ~31p |
| Banned-substance testing | Informed Sport, every batch | Not always; check for a certification mark |
Two numbers do the work in that table. The first is dose: a typical shot gives you a quarter to a half of what a KUDU sachet does, so you would need two to four of them to reach 20g. The second is cost per 1,000mg, which is what you should compare rather than the price on the box. A high dose at £34.95 for 14 works out at roughly 12.5p per 1,000mg against a UK average of about 31p. The full workings are in top liquid collagen sachets compared and the UK liquid collagen comparison 2026.
Collagen shots vs sachets vs drinks: are they the same thing?
Mostly, yes. "Collagen shot", "collagen sachet" and "collagen drink" all describe hydrolysed collagen already dissolved in liquid and ready to drink. The names describe the packaging more than the product: shots tend to come in small bottles, sachets in a tear-top pouch, drinks in larger cans or cartons. What matters is the label: how many grams of hydrolysed collagen per serving, how much sugar, and whether the collagen is hydrolysed at all, because whole collagen is too large to absorb well. KUDU is packaged as a sachet and drunk as a shot. If you are weighing liquid against powder, read liquid vs powder collagen in the UK and hydrolysed collagen vs collagen peptides.
Who collagen shots are for
Athletes and gym-goers who want a pre-training dose
Shaw 2017 gave 15g of gelatin with vitamin C about an hour before exercise and saw markers of collagen synthesis roughly double. Lee 2023 found a dose-response: 30g of gelatin produced more than 15g, and 15g more than none. In fairness, Aussieker 2023 found no increase in connective-tissue synthesis after exercise in that trial, so the picture is promising rather than settled. A 20g shot puts you at the top of the studied range without a shaker. See collagen dosage for athletes, collagen for runners and collagen for CrossFit.
Anyone who has given up on powder
Powder fails on consistency. The tub sits in the cupboard, the scoop clumps, and by week three the habit is gone. A shot takes ten seconds and travels in a gym bag, a glovebox or hand luggage. The studies that showed benefits ran for 8 to 24 weeks of daily use, so the format you will actually keep taking is the one that works.
Joints, tendons and staying active after 40
Praet 2019 (2.5g a day for six months) reported better outcomes in Achilles tendinopathy when collagen was combined with rehab. Zdzieblik 2017 (5g, 12 weeks) looked at activity-related knee pain, and Clark 2008 (10g, 24 weeks) at joint pain in athletes. Hydrolysed collagen alongside loading exercise is the combination those studies used. Start with does collagen help joint pain and collagen for tendonitis and tendon pain.
How to take a collagen shot
- One shot a day. Tear the corner and drink it straight, ideally chilled. No mixing.
- Training days: take it 30 to 60 minutes before your session, when the peptides will be circulating as the tissue is loaded. Vitamin C contributes to normal collagen formation, so a piece of fruit alongside is a sensible habit. See the best time to take collagen and collagen and vitamin C.
- Rest days: any time. If you fast in the mornings, 85 calories is not zero, so read does collagen break a fast first.
- Give it 8 to 12 weeks. Skin and nail changes tend to show first; tendon and joint studies ran 12 to 24 weeks. Subscribers pay from £1.99 a shot and can pause, skip or cancel in two clicks.

Collagen shot FAQs
What is a collagen shot?
A single small serving of hydrolysed collagen already dissolved in liquid, so you drink it rather than mix it. Doses vary enormously between brands, from around 5,000mg up to KUDU's 20,000mg, so always check the grams per serving.
How much collagen is in a KUDU shot compared with other shots?
Each KUDU sachet contains 20,000mg (20g) of hydrolysed bovine collagen. Typical UK beauty shots contain 5,000 to 10,000mg, so one KUDU sachet is roughly two to four of them.
Are collagen shots better than collagen powder?
Gram for gram it is the same ingredient. Shots win on convenience, on dose per serving and on the consistency that the studies depended on. Powder is usually cheaper per gram but far easier to stop taking.
When should I take a collagen shot?
Any time works for skin, hair and nails. For tendons and joints, the research used a dose 30 to 60 minutes before exercise, so take it before training on session days.
Do collagen shots contain sugar?
Many do. KUDU has 0g sugar, 0g fat and 85 calories per shot, with the calories coming from the 20g of collagen protein itself.
Are KUDU collagen shots safe for drug-tested athletes?
Yes. KUDU is Informed Sport certified, so every batch is tested for banned substances before it is released. The full range is on the liquid collagen collection.
