Once you've settled on a collagen source, the next fork is format: collagen powder versus capsules. Neither is higher quality than the other — they suit different routines and dosing preferences. Here's how to decide.
For transparency: in Great Britain, collagen is not authorised to carry specific health claims. This is a practical comparison of two formats, not a claim that collagen improves any aspect of health. Authorised claims, where present, come from the vitamin C paired with the collagen in our capsule products.
Collagen powder: higher dose, mix it your way
Powder's main advantage is dose. It's easy to deliver a large serving — our Bovine Collagen Powder provides 14,000mg per serving (Types I & III), unflavoured, to stir into coffee, smoothies or water. If you want a high, transparent dose and don't mind a few seconds of mixing, powder is the natural pick. The trade-offs: you need a drink to mix it into, and you measure each scoop yourself.
- Best for: higher daily doses, people who already make a morning coffee or smoothie.
- Consider: requires mixing; less convenient on the go.
Collagen capsules: convenience and precise dosing
Capsules win on convenience and consistency. There's nothing to measure or mix — you take a fixed number with water, and the dose is identical every time. They're tasteless, travel easily, and pair neatly with other supplements. Our capsule options — Marine Collagen Capsules and Bovine Collagen Capsules — also include hyaluronic acid and vitamin C. The trade-off is dose: gram-for-gram you'd take more capsules to match a big powder serving.
- Best for: convenience, travel, precise dosing, no taste.
- Consider: lower dose per unit than a powder scoop.
A quick way to decide
Ask yourself two questions. Do you want the highest dose? Powder. Do you want the least friction and a fixed dose you can take anywhere? Capsules. Diet may also steer you: our powder is bovine (Types I & III), while capsules come in both marine (Type I) and bovine — so if you've already chosen a source after reading marine versus bovine collagen, that may make the format decision for you.
One thing that matters in both
Whichever format you choose, the vitamin C question still applies: it's the ingredient that carries an authorised collagen-formation claim, and it's in both our capsule products. We explain why that pairing matters in collagen and vitamin C, and cover all the selection factors in our main guide to choosing a collagen supplement in the UK.
