5 supplements I’ve tried since my ADHD diagnosis, ranked by which ones I honestly think were worth it

My opinion only. None of these is a cure, and none of them replaces anything your doctor has prescribed. This is just a ranking of which ones I’d hand my money over for again, and which ones ended up at the back of the cupboard.

Why I bothered I was diagnosed with ADHD at 31. Before that, I’d spent about a decade buying things that were going to sort my life out. Planners. Apps. And a drawer of vitamins with three capsules missing from each bottle. Vitamins were the one I kept coming back to. Every few months I’d read something, get convinced, do an evening of research, spend £40, and then three weeks later realise I’d stopped without ever deciding to. It wasn’t that I didn’t want to take them. It was that every version I tried needed something from me every single day, and daily is exactly where I fall apart. So this time I did it properly. Five different approaches, each given a genuine go, and one question at the end of it: was this worth the money and the effort, in my opinion, for someone whose brain works like mine? This isn’t a clinical trial and I’m not a nutritionist. I didn’t judge anything on how it made me feel, because I don’t trust myself to separate a good week from a good capsule. I judged them on whether they earned their place in my life. That’s the only test I’ve got.

How I tested them

What I looked for before ranking them

I ran the same checks on all five. I was looking for something I’d still be doing in March, not the longest ingredient list.

  • How many decisions it needed before I could even start
  • How many things I had to remember each morning
  • What happened when I ran out
  • Whether it survived a bad week
  • What it actually cost, including bottles I abandoned halfway through
  • Whether I could see why each thing was included, or was just trusting a label

Alyve personalised vitamins photographed at home during testing

Alyve was the first one that felt designed around how I actually live rather than how I’m supposed to. The quiz took about three minutes and asked about my diet, my usual routines and what I wanted from it. It came back with one named formula, around two capsules, in one glass jar. It shows you why everything is included, which mattered to me because I’ve never trusted things when I can’t see the reasoning. The other thing that surprised me was how specific it felt. The formula clearly reflected the answers I’d given rather than a general list made for everyone. That sounds small, but for me it’s the difference between something I trust and something I’m just tolerating. Then the bit that made the difference: it turns up on its own. With next-day subscription delivery, it arrived before I ran out. I never had to remember to reorder, and reordering is the exact point where every other supplement I’ve owned quietly died. I’m not going to tell you it changed me. It didn’t, and this isn’t an ADHD treatment. What it did was take a task I’d failed at for ten years and reduce it to picking up a jar that was already on the table. For me, that was worth £29 a month.

What I liked

  • The quiz makes the decision for you, so there is less research to do
  • Built around what I actually flagged in the quiz, so it felt like mine
  • Around two capsules in one jar replaced a cupboard of half-used bottles
  • Delivered before I ran out, so I did not have to remember to reorder
  • Free nutritionist access and an AI nutritionist in the app when I had questions
  • 60-day money-back guarantee

What to know

  • You need to complete the quiz before you see your formula
  • It is a subscription, though you can pause, change or cancel

My verdict: The only one on this list I’m still taking, and the only one that asked almost nothing of me day to day.

Heights Vitals+

4.7 · 6,000+ reviews shown by Heights

£30–£40/month on subscription

Heights Vitals+ photographed at home during testing

Heights was the easiest of the fixed formulas to live with. Two capsules, a nice bottle, no mixing. Its fixed formula goes to everyone, so it is a well put together product that is not built around any one person’s answers. I kept it going for about six weeks, which by my standards is a good run. The main reason it slipped was the reorder: it ran out on a bad week, and a bad week is not when I go and set up a new order.

What I liked

  • Simple two-capsule routine
  • Clear, straightforward labelling
  • No taste or mixing

What to know

  • One formula for everyone
  • I had to stay on top of reordering myself

My verdict: A good, tidy capsule routine. Worth it if you’re better than me at remembering to reorder.

3★★★☆☆

AG1

75 · ingredients promoted by AG1

Around £79–£99/month on subscription

AG1 photographed at home during testing

I wanted to like AG1, and on good mornings I did. There is a proper ritual to it, and the breadth of the formula is genuinely impressive. The problem for me was that the ritual was the product. On a bad week the shaker sat in the sink for three days and the pouch went unopened. Once I had missed a few days, the sunk cost started to sting. At this price, a product I only manage on good weeks is not one I can justify.

What I liked

  • Very broad daily blend
  • Third-party testing highlighted by the brand
  • A pleasant ritual when I had the headspace for it

What to know

  • The most expensive option here by some distance
  • Needs mixing every day, and a shaker to wash

My verdict: Great if a daily green drink already fits your life. For me it was a good-week product at a full-month price.

4★★★☆☆

A high-street multivitamin

Own-brand · one a day

Around £6–£8 a bottle (estimated; offers vary)

A high-street multivitamin photographed at home during testing

This is the one almost everyone has tried. Cheap, one tablet, sat next to the till. There is nothing wrong with it, and I would never tell anyone it is a waste of money. The issue for me was that it was so easy to buy that it was equally easy to ignore. Nothing about it was mine, I could not have told you what was in it without reading the back, and it lived in a drawer, so it stopped existing within a fortnight. I do not think the product failed. I think I did, and it gave me no help not to.

What I liked

  • Cheap and available almost everywhere
  • One tablet, no fuss

What to know

  • One formula for everyone
  • Nothing to keep you on track once the novelty wears off

My verdict: Fine, but for someone like me, fine did not survive week three.

5★★☆☆☆

The DIY stack

Four · separate bottles

Roughly £25–£40/month across four bottles (estimated)

The DIY stack photographed at home during testing

I have built this kind of stack at least four times. Each time it starts with an evening of research, a basket of separate bottles, and a real sense that I have finally cracked it. Then reality arrives: four bottles, four different directions, four different run-out dates, and a kitchen counter that looks like a chemist’s. By week three I was taking two of the four, then one, then none. The bottles are still in the cupboard. Some are still mostly full. I am not ranking this last because the individual products are bad. I am ranking it last because the format asks more of me than any other option here, and I have now proven four times over that I cannot sustain it.

What I liked

  • You choose exactly what goes in
  • Individually, each bottle can be inexpensive

What to know

  • The research and directions are all on you
  • Four bottles means four things to remember and four things to reorder

My verdict: The one I would most gently steer people like me away from, purely on effort.

The final verdict

The final verdict: why Alyve was the one worth it

Every product on this list is a reasonable thing to buy. Four of the five, though, needed something from me every day or every month, and the something was always the thing I am worst at. Alyve was the only one where the effort happened once, on a Tuesday evening, filling in a quiz. Since then it has just been there: on the table, before it ran out, built around the things I had actually told it about, with someone qualified to ask when I had a question. If you have a cupboard of bottles you have stopped taking, I do not think that is a willpower problem. I think it is a design problem. This was the first supplement I found that was designed around the way I actually live, and that is why, in my opinion, it was the only one worth it.

The DIY stack section is me. Four bottles, all half full, all expired. Thank you for not pretending you’d cracked it on the first go.

Refreshing to read one of these that does not claim a vitamin fixed someone. The reorder point is exactly where I always fall off.

I did the quiz after reading this. It took me about four minutes and explained everything in the formula, which is more than any of my cupboard bottles ever did.
