We've all done the maths the morning after. Two glasses of water before bed, a paracetamol, a greasy breakfast, and somehow you still feel like you've been hit by a bus. The headache you understand. The bone deep, can't think, can't function tiredness is the part that doesn't seem fair.
Here's the thing most hangover advice skips. A good chunk of how rough you feel isn't just dehydration. It's happening down at the cellular level, in the way your body deals with alcohol. And NAD+, the molecule your cells use to make energy, gets pulled right into the cleanup.
Let me walk you through what's actually happening, why the recovery gets slower as you get older, and what genuinely helps. No miracle cures, because there aren't any.
First, what your body does with alcohol
When you drink, your liver gets to work breaking the alcohol down. It does this in two main steps, and both of them lean heavily on NAD+.
Step one turns alcohol into a nasty little compound called acetaldehyde. This is the stuff that's largely responsible for feeling awful. Step two breaks acetaldehyde down into something harmless your body can clear out. Both steps need NAD+ to run.
So while your liver is processing last night's drinks, it's burning through NAD+ to do it. The more you drink, the more NAD+ gets tied up in the queue. And NAD+ is the same molecule your cells rely on for everyday energy production. Start to see the problem? Your body is rationing a resource it also needs just to keep you feeling normal.
That's a big part of why a hangover isn't only a sore head. It's a whole body energy slump while your cells sort out the mess.
Why it gets worse with age
If you've noticed that hangovers in your thirties hit harder than they did at uni, you're not imagining it.
Your NAD+ levels naturally decline as you get older. So you're starting with less in the tank to begin with, and then a night out drains even more of it. Younger you had a deeper reserve to draw on. Older you is working with a thinner margin, which is one reason the same number of drinks can wreck a whole day now when it used to cost you a slow morning.
It's a bit deflating, but it also explains a lot.
What actually helps the morning after
Right, the useful part. Nothing on this list is a magic switch, and anyone selling you an instant cure is having you on. But these genuinely give your cells a better shot at recovering.
Water first, obviously. Alcohol dehydrates you and throws your electrolytes off, so rehydrating with something that has a bit of salt and minerals in it does more than plain water alone.
Eat something real. Your liver is doing a metabolic marathon. Give it actual fuel rather than just more coffee and regret.
Sleep, if you can get it. Alcohol wrecks the quality of your sleep even when you're out cold for hours, so a genuine lie in or an early night the day after matters more than people think.
Don't punish yourself with a hard workout. A gentle walk and some daylight beats hammering yourself at the gym while you're already depleted.
And support your NAD+. Since your cells have just spent a load of it clearing alcohol, this is exactly the kind of moment a NAD+ product is designed for. Our SmartStrip+ dissolves on your tongue in seconds, no needles, no pills to wrestle with when you're feeling delicate. It's an easy thing to reach for on a morning when reaching for anything feels like a lot. We do pen and vial options too if you prefer a higher dose.
To be clear, this isn't about drinking more because you've got a recovery routine. It's about being a bit kinder to your cells when you have had a big one.
A quick honesty check
NAD+ won't undo a night of drinking, and it isn't a licence to overdo it. The research on alcohol burning through NAD+ is solid biochemistry, but "NAD+ cures hangovers" would be overselling it, and we'd rather be straight with you. The best hangover strategy is still the boring one: drink less, drink slower, and keep the water going through the night.
The short version
Alcohol makes your liver burn through NAD+ to break it down, which leaves your cells short on the very thing they use for energy. That's a big reason hangovers flatten you the way they do, and why they hit harder as your natural NAD+ levels drop with age. Water, food, sleep and a gentle day all help your recovery, and supporting your NAD+ is a sensible part of that stack.
So next time you're staring at the ceiling the morning after, you'll at least know what your cells are dealing with.
If big nights are part of your life, it's worth having an easy recovery habit ready to go. Try a SmartStrip+ routine. Needle free, fast dissolving, and simple enough to actually use when you need it most.
What's your usual morning after ritual? The greasy fry up, the long walk, or hiding under the duvet until noon?
