3 reasons to take a collagen supplement this winter
3 Reasons to Take a Collagen Supplement This Winter
Winter is hard on the body. Cold, dry air plays havoc with our skin, the short dark days leave us feeling flat, and energy levels seem to drop the moment the clocks go back. A daily marine collagen supplement won't fix winter — but the right one can be a genuinely useful part of your cold-weather routine. Here are three honest, evidence-led reasons to keep a 10g daily sachet of Kollo in your routine through the winter months. For the full foundations, our complete guide to liquid marine collagen covers everything in detail.
1. Support Your Skin Against the Cold
When the weather turns, skin is the first to suffer — dry, tight, and prone to flaking. This is where collagen has its strongest evidence, and it lines up neatly with what winter throws at us. A 2023 systematic review and meta-analysis in Nutrients, pooling 26 randomised controlled trials and 1,721 participants, found that hydrolysed collagen supplementation significantly improved skin hydration and elasticity compared with placebo.
One honest boundary: a supplement supports skin from the inside, but it doesn't replace a good moisturiser and barrier care when the air is cold and dry. Think of it as the inside half of a dual approach — and give it the full 12 weeks, since that's the timeframe the trials used.
2. Vitamins That Genuinely Support Energy
It's no coincidence that energy dips in winter. Kollo is fortified with vitamins B1, B5, B6 and B12, which carry authorised UK health claims for contributing to normal energy-yielding metabolism — the process by which your body releases energy from the food you eat. B5, B6 and B12 additionally contribute to the reduction of tiredness and fatigue, and B12 and B6 contribute to normal psychological function.
To be precise about what that means: these are vitamin claims, not collagen claims, and they describe supporting normal function — not curing winter tiredness or low mood. We've deliberately removed older wording that linked B vitamins to depression risk, because that overstated the evidence. What we can say, accurately, is that a daily top-up of these vitamins supports normal energy metabolism through the season when many of us fall short.
3. The Immune-Season Vitamin C Bonus
Through cough-and-cold season, vitamin C earns its place. It carries authorised UK health claims for contributing to the normal function of the immune system and to the reduction of tiredness and fatigue, and it also contributes to normal collagen formation for the normal function of skin — a neat double role in a collagen supplement.
Here's the careful bit: vitamin C supports normal immune function; it doesn't prevent or treat colds, flu or any specific illness, and neither does collagen. We've removed the old claims about collagen "repairing the gut" and immunity living in your digestive system — the clinical evidence doesn't support those, so they're gone. The accurate version is simpler and still worth having: a daily dose of vitamin C supporting your immune system's normal function.

Winter is demanding, and no sachet changes that. What a daily 10g dose of Kollo offers is real and worth having: evidence-backed support for skin hydration and elasticity when the cold is drying you out, plus B vitamins and vitamin C with authorised claims for energy and immune function. It won't ward off colds, lift depression or repair your gut — and we'd rather tell you that than sell you a winter miracle.
Pair it with the basics that actually move the needle in winter: warm layers, good sleep, decent food, hydration and daylight when you can get it. For women navigating the colder months alongside other midlife changes, our women's wellness guide for over 40s puts it all in context. And whenever you're ready, the complete guide to liquid marine collagen has the full detail on dose, format and the 12-week timeline.
