There are SO many benefits to taking a collagen supplement like Kollo!
The Real Benefits of Taking Kollo — and How and When to Take It
Search "collagen benefits" and you'll find lists that promise everything short of world peace. We'd rather give you the honest version: what 10g (10,000mg) of daily Naticol® marine collagen is genuinely supported to do, what's still unproven, and the practical answers on timing, food and how to actually take it. For the complete foundations, our complete guide to liquid marine collagen goes deeper on all of it.
What the Evidence Genuinely Supports
Skin leads the field. A 2023 systematic review and meta-analysis in Nutrients — pooling 26 randomised controlled trials and 1,721 participants — found hydrolysed collagen supplementation significantly improved skin hydration and elasticity versus placebo. Smaller studies suggest benefits for nail strength. For joints, a 2023 meta-analysis of randomised trials found collagen peptides were associated with modestly reduced knee osteoarthritis-related pain — and if joints are your main focus, our guide to joint supplements covers the wider evidence properly.
And what about the rest of the internet's list? Hair evidence is limited. Bone research is early-stage and should be read cautiously. Claims about heart, gut and brain health are not well supported for collagen, and we don't make weight loss claims at all — collagen isn't a filling protein source and no good trial shows it drives weight loss. You'll never see those promises from us, because the evidence isn't there.
Can Collagen Improve Your Mood?
A previous version of this article said B12 "helps you produce serotonin" — that overstated it, so here's the accurate version. Vitamin B12 carries authorised UK health claims for contributing to normal psychological function and to the reduction of tiredness and fatigue, as do vitamins B6 and C in Kollo's blend. That's the regulator-recognised wording, and it's meaningful enough without dressing it up as a happiness chemical.
How to Take Kollo
This is where collagen genuinely earns its convenience reputation. Kollo comes in pre-measured, fuss-free sachets that travel anywhere — handbag, gym bag, suitcase. Take it straight from the sachet, add it to a glass of water, or get adventurous: plenty of Kollo customers blend it into smoothies or juice. If you're the smoothie type and weighing up formats more broadly, our complete guide to collagen powder compares the options honestly — the short version is that the hydrolysis process matters more than the format.
Before or After Food? Morning or Evening? The Honest Answer
You may have read that taking collagen on an empty stomach "increases your chances of better results." We've looked, and there's no good clinical evidence for that — the trials behind the 2023 meta-analyses didn't require fasting, and your digestive system handles collagen peptides perfectly well alongside food. The same goes for time of day: no strong evidence favours morning over evening.
What the research consistently supports is much simpler: daily consistency over 8 to 12 weeks. So the best time to take Kollo is whichever time you'll never forget — for most people that means anchoring it to an existing habit, like the kettle boiling in the morning. If a different slot suits your routine better, take it then. The habit is the active ingredient.
Taking Kollo at a Glance
| Question | The evidence-led answer |
|---|---|
| How much? | One sachet daily — 10g (10,000mg) of Naticol® marine collagen peptides |
| With or without food? | Either — no good evidence an empty stomach improves results |
| Best time of day? | Whenever you'll be consistent — no evidence favours a specific time |
| How to take it? | Straight from the sachet, in water, or blended into smoothies or juice |
| How long until results? | Most trials measure at 8–12 weeks; Kollo recommends a 12-week commitment |
| What else is in it? | Vitamins B1, B5, B6, B12 and C, plus the amino acid l-lysine |
Getting the Most From Your Sachet
- Anchor the habit — pair your sachet with something you already do daily, because consistency beats timing every time.
- Commit to 12 weeks — that's the timeframe the meta-analyses support, so judge results then, not at week two.
- Keep the foundations in place — a balanced diet, regular exercise and good sleep do the heavy lifting; no supplement fixes an unhealthy lifestyle, and we'll never pretend otherwise.
- Vitamin C is built in — it carries an authorised UK claim for contributing to normal collagen formation for the normal function of skin, a genuinely useful bonus in a collagen formula.
- Trust the testing — Kollo is Informed Choice certified, with every batch independently screened for banned substances.
