Liquid collagen that actually delivers a working dose
Most liquid collagen sold in the UK is built for the beauty aisle: 5,000 to 10,000mg per shot, a few grams of sugar, and a price that works out at 30p or more per 1,000mg. KUDU is the other way round. Every 63g sachet delivers 20,000mg of hydrolysed bovine collagen (20g of protein), with 0g sugar, 0g fat and 85 calories, ready to drink with no mixing. It is the dose the tendon, joint and skin studies actually used, in a format you can finish in two sips on the way to training.

Liquid collagen vs powder vs tablets
| | KUDU liquid sachet | Collagen powder | Tablets / capsules |
| Collagen per serving | 20,000mg | 5,000–10,000mg per scoop | 500–1,000mg per tablet |
| Preparation | Tear, drink | Scoop, mix, shake | 10–20 tablets for a 10g dose |
| Absorption | Hydrolysed peptides already in solution | Hydrolysed, needs full dissolving | Slow, low dose |
| Sugar | 0g | Varies | 0g |
| Cost per 1,000mg | 12.5p one-time | UK average ~34p | Highest per mg |
The important word is hydrolysed. Collagen has to be broken into short peptides before the gut can absorb it, and a ready-mixed liquid means those peptides are already in solution. Read our full liquid vs powder comparison, or the science on how collagen is absorbed.
Who KUDU liquid collagen is for
Athletes, runners and gym-goers
The research on tendons and ligaments used 5g to 20g of hydrolysed collagen taken around an hour before training. One KUDU sachet covers the top of that range in one go. See collagen for athletes compared and the best protein sources for muscle recovery.
Skin, hair and nails
Skin elasticity and hydration studies typically ran at 2.5g to 10g a day for 8 to 12 weeks. A 20g shot means you never fall short of the studied dose, and you get 20g of protein towards your daily total at the same time. More in protein and ageing skin.
Joints, injury recovery and staying active after 40
Natural collagen production falls from your mid-twenties and drops sharply for women around menopause. Daily hydrolysed collagen plus loading exercise is the combination the tendon-repair studies found most useful. Start with how much collagen you should take per day.
How to take liquid collagen
- One sachet a day, any time. Straight from the sachet or over ice.
- Training days: take it 30 to 60 minutes before your session so the peptides are circulating when the tissue is loaded.
- Give it 8 to 12 weeks. Skin changes show first; tendon and joint benefits take longer and stack with training.
- Stay consistent. Subscribers save 20% rising to 30% and get free UK delivery, and you can pause, skip or cancel in two clicks.
Marine or bovine liquid collagen?
Both are hydrolysed into similar peptides. Bovine collagen provides both type I and type III, which is why we use it for a product aimed at skin and connective tissue, and it lets us deliver 20g per sachet at a price marine collagen cannot match. The full comparison is in marine vs bovine collagen.
Liquid collagen FAQs
Is liquid collagen better than powder?
Per gram they are the same ingredient. Liquid wins on dose per serving, convenience and consistency: you are far more likely to take a sachet you can drink in two sips every day than to mix a powder. KUDU also delivers 20g per serving, which is two to four times a typical scoop.
How much liquid collagen should I take a day?
The evidence base sits between 2.5g and 20g of hydrolysed collagen per day depending on the goal. One KUDU sachet gives you 20g, the top of the studied range, so one a day is enough.
Does KUDU liquid collagen contain sugar?
No. Each sachet has 0g sugar, 0g fat and 85 calories.
Is it safe for drug-tested athletes?
Yes. KUDU is Informed Sport certified, which means every batch is tested for banned substances before it is released.
Is liquid collagen gluten free and dairy free?
Yes, KUDU liquid collagen is both gluten free and dairy free. It is made from bovine collagen so it is not suitable for vegetarians or vegans.
How long does liquid collagen take to work?
Most people notice skin and nail changes at 4 to 8 weeks. Tendon, ligament and joint studies ran for 12 to 24 weeks alongside training. Our 60-day guarantee covers the first two months.
