Collagen powder: frequently asked questions
What is marine collagen powder?
Marine collagen powder is hydrolysed type I collagen from fish skin, dried into a fine powder. The peptides are small enough to dissolve fully and absorb easily. Kollo's powder uses Naticol® 4000, a named marine collagen peptide with its own published human studies, at 10,000mg per serving.
How much collagen powder should I take a day?
Clinical studies on skin, hair and joint outcomes used 2.5g to 10g a day, with the most consistent results at 10g over 8 to 12 weeks. One Kollo serving (one scoop or one sachet) provides 10,000mg. Read our guide to how much collagen per day.
How do I take collagen powder?
Stir one serving into any drink - water, coffee, tea, a smoothie, porridge or yoghurt. Add the powder to a little liquid first, stir, then top up to avoid clumps. It is unflavoured, so it does not change the taste of what you add it to. See how to mix collagen powder.
Does heat destroy collagen powder in coffee?
No. Hydrolysed collagen peptides are stable at the temperatures of hot drinks, so adding collagen to coffee or tea does not reduce its effectiveness. Our article on collagen in coffee covers the evidence.
Pouch or sachets - which should I choose?
Same powder, same 10,000mg dose. The 30-serving pouch is the lower-cost option if you take it at home every day; the single-serve sachets are for travel, work or anyone who prefers a measured dose without a scoop.
Should I choose collagen powder or liquid collagen?
Both Kollo formats deliver 10,000mg of the same Naticol® 4000 collagen. The powder is unflavoured and mixes into food and drink; the liquid sachet is ready to drink and includes B vitamins and L-lysine. Pick the one you will take every day. Our liquid vs powder guide has more detail.
How long does collagen powder take to work?
Most people notice changes in skin hydration and nail strength within 4 to 8 weeks of daily use, with joint comfort and hair typically taking 8 to 16 weeks. Taking it every day matters more than the time of day. See our results timeline.
Who should not take collagen powder?
Marine collagen is not suitable for anyone with a fish allergy. If you are pregnant, breastfeeding or taking prescription medication, speak to your GP or pharmacist before use. Collagen supplements are not a treatment for any medical condition.
