The autumn reset, a sensible nutrient check-in (without the alarm)

There's a particular kind of September article that opens by telling you summer has wrecked you. Too much rosé, too many crisps eaten standing up in a caravan, and now it's time to atone.

We're not doing that one. Summer was good for you. Sunshine, longer days, more time outside, food eaten with other people — those are genuinely healthy things, and the fact that some of them came with a glass of something is not a moral failing requiring a cleanse.

But something did change over the summer, and something else is about to. Both are worth ten minutes of attention now, while it's easy, rather than in February, when it isn't.

That's all an autumn reset is. Not a purge. A check-in.

Three things, and they're all practical rather than dramatic.

The sunlight stops doing a job it's been doing since March. From around October, UK sunlight no longer carries enough UVB for your skin to make vitamin D. That's not a health scare, it's astronomy. We sit too far north for the sun to get high enough in the sky. But it means one nutrient that has been arriving free all summer stops arriving, and starts drawing down from storage instead. By January to March, 31% of UK adults aged 19–64 are vitamin D deficient, up from 18% across the year as a whole. We wrote about exactly why that happens here.

Your routine changes shape. Summer eating is loose, varied and social. Autumn eating gets more repetitive.  Same few meals, eaten indoors, on a schedule. Repetitive isn't automatically worse, but a narrower diet has narrower nutrient coverage, and it drifts without anyone deciding it should.

The daylight goes. Less morning light disrupts sleep timing, and there's less appetite for exercise in the dark and wet. Both of these affect how you feel considerably more than any supplement does, which is worth saying out loud on a supplement company's blog.

Nothing there is an emergency. It's just a set of predictable, seasonal changes, the kind you can plan around precisely because they're predictable.

Take these honestly. The point is to find the one or two things worth changing, not to collect a shopping list.

1. Are you covering vitamin D from October?

The one nutrient where the answer is nearly always yes, and the least debatable item here. The UK government recommends everyone consider a daily supplement containing 10 micrograms (400iu) through autumn and winter — that's the NHS position, not ours.

If you take nothing else on this page, take this one. Our autumn dose is D3 2500iu, made from lichen rather than sheep's wool. If tablets are a struggle, the 1000iu spray does the same job differently; if bone health is your particular focus, D3 with K2 pairs the two. Different formats for different people — not a ladder to climb.

2. Has your diet narrowed since August?

Not "has it got worse" — has it got narrower. Fewer different plants, more of the same three dinners.

If yes, the gap-filler is a properly formulated multivitamin. MultiVit covers the range — zinc, selenium, copper, vitamin A, vitamin C, the B vitamins, iron — with the nutrients where more genuinely isn't better held at 100% of NRV and no higher. The one that looks enormous on paper is B12 at 50µg, and that's a response to how little of it you can absorb from any single dose rather than a bigger-is-better number (we explain why here). Sensible amounts, in other words, not impressive-sounding ones. If your diet's still broad and varied, you may genuinely not need it, and we'd rather say so.

3. If you're plant-based, is your B12 sorted?

The one genuinely non-negotiable nutrient for anyone eating fully plant-based. It doesn't reliably occur in plant foods, and running low is a slow, quiet problem rather than a sudden one — which is exactly what makes it easy to leave unchecked for years.

Two routes, and the choice is about your gut, not your diet: 1000mcg sustained release if your absorption is fine, or 100mcg sublingual if it isn't — the sublingual dissolves under the tongue and bypasses the gut altogether. If it's been more than a couple of years since anyone looked at your B12 status, that's a GP conversation worth having.

4. Are you still getting omega-3s without thinking about it?

Summer salads, and whatever you were eating on holiday, tend to carry more variety than a winter of the same warm dinners. Omega-3 has authorised claims for the maintenance of normal brain function and vision (DHA) and normal heart function (EPA and DHA) — and ours comes from the microalgae where those fatty acids originate, rather than from fish that ate the algae first.

Straight from the source, in other words. Fewer intermediate fish.

5. What are you actually sleeping like?

The question with no product attached, and the one most likely to make a difference.

If the honest answer is "badly, and it started when the mornings got dark", then light in the morning, a consistent wake time, and less screen at night will do more for how you feel this winter than anything we sell. We'd rather tell you that than pretend otherwise. (If it's magnesium you're curious about, it's there but fix the light and the timing first.)

No detox. Your liver and kidneys have that covered, continuously, for free, and have done since before the word appeared on a juice bottle.

No "immune boost". As we covered in the last blog, no supplement is permitted to claim it boosts immunity, because the evidence doesn't support it. What the authorised claims actually say is that certain nutrients contribute to the normal function of the immune system, they're building materials, not a volume dial.

No megadoses. On several of these nutrients, selenium especially, more is genuinely not better, and the gap between enough and too much is narrower than people assume.

No January framing. The reason to do this in September is that a store topped up gradually never runs down far enough to need rescuing. Acting now is less work than reacting later, which is the entire argument.

We started with the brain, and the fact that it's around 60% fat by dry weight, which is why the omega-3s you eat are structural rather than optional. Then the gut, and the awkward truth that what you swallow and what you absorb are two different quantities, which is why sublingual B12 exists at all. Then skin and hair, the visible output of everything underneath, where the honest story is amino acids and vitamin C rather than collagen applied directly to your face. And now immunity, which turns out to run on the same ordinary nutrients as everything else.

Four months, and the same idea underneath all of them: the body is a system, and it's running on what you give it. Not on a hero ingredient. Not on a boost. On adequate supply, consistently, over a long time.

That's a harder thing to sell than a miracle. It's also the only version that's true, and we'd rather be the brand that told you.

Ten minutes, five questions, one or two changes. That's the whole reset. Then go and enjoy the autumn, it's the good season, whatever the January people tell you.
