Key Takeaways
- Most people keep it short. Of 437 people who listed their own routine, 231 named just 1 to 3 products, and only 39 named 8 or more
- Everyone starts from the same base: vitamin D, magnesium, fish oil and a multivitamin. Heavy stackers add things like zinc, turmeric, theanine, NAC and ashwagandha on top
- When people cut their whole routine, something rarely went wrong, and 56 of the 93 who explained why named money, hassle or doubt with no bad reaction
- When people drop just one product it's usually the opposite, and 41 of 70 named a bad reaction
- People keep a product when they feel it working, or feel worse when they stop. Vitamin D is the exception: it is the product people keep most, often with no felt difference at all
The question behind this study was simple: some people take one or two supplements and some take fifteen, so how are they different? How do they explain each new bottle, and what finally makes them cut back or stop?
The short answer is that both groups start with the same few products, and most people who stop taking everything never had a side effect.
We analyzed 7,200+ comments about supplement routines. Of 437 people who listed their own, 231 named 1 to 3 products and 39 named 8 or more. Of 93 people who cut back several products and said why, 56 named money, hassle or doubt and no bad reaction. Of 70 who dropped a single product, 41 named a bad reaction.
About this study
- Corpus
- 7,200+ public comments from 253 discussions where people talk about their own supplement routines, adding products, cutting back and all-in-one products. 4,402 are directly about supplements. We sorted by hand the comments where people describe their own routine. That includes why they added or cut something, what convinces them a product works, and what they spend
- Communities
- General supplement forums, biohacking and longevity communities, health podcast fan communities, fitness and strength training groups, women's and midlife communities, fertility, PCOS and weight-loss surgery groups, and frugal living forums
- Themes coded
- How many products people take, why a product gets added, what earns a product its place, why people cut back, what people say about all-in-one products, and what a routine costs
- Analysis
- We sorted each comment into themes by hand. One comment can fit more than one theme, so the percentages only describe their own section and don't add up to 100, which makes them rough guides rather than exact measurements.
- Quotes
- Every quote is word for word. We only fixed broken characters, so the wording, spelling and typos are the commenter's own.
There are a few things you should know about how I collected this. I expected the biggest thread, about pill organizers, to be really useful. It wasn't. Most of it was about prescription medicine, so I left it out. When I searched for people who "started" or "added" a product, I mostly got advice to other people, so I read and sorted that section line by line. And since everything here is people describing what they take, none of it says whether a product is safe, works, or is right for anyone.
The research question
How are heavy supplement stackers different from minimalists? I wanted to know what each group buys, how they explain each new product, and what finally makes them simplify or stop. The short version is that both groups buy the same basic products and the stackers keep adding more on top. People usually add a product to fix something they can feel, and they drop the whole routine when they can't feel anything or it costs too much.
1. Who stacks and who keeps it short
Three kinds of routine, by how many products people name437 people listed what they take, and when I counted the products each one named, most routines turned out to be short.
One caveat: people often leave things out when they list their routine, so these counts are probably a bit low.
What's more useful is what each group actually takes, so the table below shows how many people in each group name each product.
| Product | 1 to 3 | 4 to 7 | 8 or more |
|---|---|---|---|
| Vitamin D | 29% | 63% | 67% |
| Magnesium | 23% | 62% | 90% |
| Multivitamin | 29% | 41% | 46% |
| Fish oil | 19% | 49% | 72% |
| Creatine | 12% | 19% | 44% |
| Zinc | 3% | 19% | 44% |
| Turmeric | 1% | 5% | 31% |
| L-theanine | 2% | 5% | 23% |
| NAC | 4% | 4% | 18% |
| Ashwagandha | 2% | 5% | 18% |
| Lion's mane and other mushrooms | 3% | 3% | 18% |
| Berberine | 0% | 1% | 13% |
Two things stand out. First, almost everyone takes some of the same four products: vitamin D, magnesium, fish oil and a multivitamin. People with long routines take them too, but they add more on top, mostly herbs and products for focus, sleep or ageing that short routines almost never include.
Second, the multivitamin works differently from the rest. In short routines it's tied with vitamin D as the most common product, but in long routines it drops to fourth place. Many people with short routines seem to take one multivitamin instead of several separate products.
"I just take a 50+ women's multivitamin since I hit official menopause a couple of months ago."
"I take the basics, omegas, vit d, sometimes c, magnesium and collagen. I don't care to take anything else."
"I've been collecting supplements like trophies over the years, it feels like!"
"I probably have a hundred different supplements, 60 of which I take regularly, 40 of which I take daily."
If you sell a basic product like vitamin D, magnesium, fish oil or a multivitamin, almost every supplement user is a possible customer. But if you sell an extra like NAC or a mushroom blend, you're selling to a much smaller group of heavy users. They're also the people most likely to stop everything later.
2. Why a product gets added
Ten reasons, ranked by how often people mention them52 people said why they started taking a specific product, and most of them wanted to fix a problem they could feel, like bad sleep or pain.
Small group, so treat the order as a rough guide. I expected podcasts to be near the top, since a lot of these communities grew up around health podcasts. They came fifth. Maybe people mention the problem they wanted to fix and not where they first heard about the product.
"Recently was having pretty bad fatigue and just picked up some centrum because it was convenient and felt way better quickly."
"I started taking it about a decade ago when a neurologist suggested them (along with magnesium and B) for my frequent migraines. They were so helpful that I never revisited them."
"I bought some creatine after listening to one of the Galpin episodes, but on some level, I just don't want to complicate my life any more, and I haven't started a course."
A few comments show how a routine grows over time. People add a product for a good reason, and years later they've forgotten the reason but they're still taking it.
"my stack tends to grow too. I run across something new to try and it gets added. Then every once in a while I do a culling."
"i dont even remember why i take some of the stuff anymore i just know i had a good initial reason"
"I recently started systematically adding all my leftover supplements to my current routine. They were too ineffective to keep buying them but too expensive to just throw out."
3. What earns a product its place
Five kinds of proof, ranked by how often people mention them101 comments describe what convinces someone to keep a product or drop it, and most people trust what they feel in their own body more than anything else.
About half are about something people felt, either while taking the product or after they stopped. The same few products come up again and again here, mainly magnesium for sleep, creatine, B12 and collagen for joints.
"B12 and creatine are the only ones I really notice when I stop."
"I notice pain in my joints if I don't take collagen for a couple of days. I'm hooked."
"I only take a supplement if my blood work shows I need it. Otherwise it's just money flushed down the toilet. Literally."
Vitamin D works differently. In three threads asking which supplement people would never give up, 234 comments named a product. Vitamin D came first with 56, ahead of magnesium (45), creatine (35) and fish oil (20). But it's also the product people most often say they can't feel, so they keep it because of a blood test, the winter, or their doctor.
"I take magnesium (which has helped with my sleep massively) and vitamin D (never noticed any difference but it's good practice to take this in winter apparently)."
"I take about a dozen supplements and I can only feel two of them but that's okay because I don't expect to have perceptible impacts from the others"
"I do not feel the slightest difference during the months I'm taking a fair bit of supplements and the months I'm not."
If customers can't feel your product, something else has to keep them buying. Vitamin D has blood tests and habit, but most other products don't, so the brand has to tell customers what to notice and when. "Expect better sleep in 2 weeks" gives people something to check, and "supports overall wellness" doesn't. As the next section shows, not feeling anything is the main reason people quit.
4. Why people cut back
Two kinds of cutting, and the reasons behind eachWe read 566 comments about stopping or cutting back, and in 189 of them people described what they had stopped themselves. They split into two very different groups: 114 people cut several products or their whole routine, and 75 dropped just one product. The list below covers the 93 people in the first group who said why.
67 of the 93 named money, hassle or doubt, and 56 named one of those without any bad reaction. So about 6 in 10 people who cut back a whole routine never had a side effect. Not one. Doubt is the most common reason, and it usually comes from taking something for months without being able to tell if it did anything.
"The two biggest reasons were the money and the lack of noticeable effects."
"Constant researching and checking levels and taking this and because you take that you need to take these cofactors and also take this!"
"I am finishing a month of traveling and forgot all my supplements and barely have noticed. I will probably cut down significantly."
"I don't wanna waste them but I also get tired taking them but don't always feel good."
I saw this a few times. People don't always decide to stop: they miss a week by accident, feel no different, and just never start again, so the brand never finds out why.
Single products? The opposite. 41 of the 70 people who dropped one product named a bad reaction. To be fair, two threads asked people directly about supplements that made them feel worse, and 22 of those 41 come from there. But even without those threads it's 19 of 48, still the biggest reason by far.
"Glucosamine makes my joints hurt worse. I tend to forget that, and try taking it again every few years. Then I remember why I stopped."
"Ashwaganda for me too. Gave me anxiety so bad I had to seek help."
Not everyone is happy about cutting back, though, and a few people who stopped to save money felt worse afterwards.
"I honestly stopped taking my mine because I am poor. I can honestly say that I feel a difference negatively."
"I've cut back from 15 to about what, 3? Fish oil, multivitamin, nmn, beta alanine. Ok, 4."
A better formula won't fix most of this. The formula was never the problem. Against doubt, tell customers what to watch for and when to expect it, and against hassle, cut the number of pills. Cost is harder to fix, but when people cut back they keep the products they can feel, so make sure yours is one of them.
5. The all-in-one question
What people say about all-in-one products, ranked by how often it comes upIf hassle is a big reason people quit, one product instead of ten bottles sounds like the answer, right? 209 comments talk about all-in-ones, greens powders and personalized vitamin packs. Most are about one brand, AG1, and a lot of them come from threads about its podcast sponsorships, so keep that in mind when you read the list below.
What people like about them is the same thing stack-cutters want: fewer pills. One scoop instead of ten pills makes life easier for older parents and for anyone who hates swallowing tablets.
"Yeah I get that, to me it's "just one pill", super simple and low maintenance."
"Now I order AG1 because it's better than not actually making my smoothies."
"They would not to take 5 or 6 different supplement pills along with their medical pills."
And the complaints? Mostly about trust, because people don't believe a product sold through podcast ads and they don't like labels that hide the doses. One complaint is about the format itself, though: if one ingredient gives you a side effect, you can't tell which one it is.
"I used it for a while but started to get skeptical. They won't tell the amount of the various ingredients."
"Personally I think all-in-one supplements are problematic because if you have a negative response to one ingredient, you have a negative response to the whole product."
"AG1 at $99/month: Hated the first few uses and threw the rest out, overhyped and overpriced"
"I take garden of life but still needed extra for specific things. I'm losing faith in all-in-one multivitamins."
People who cut back would happily buy something that makes their routine simpler. If they trust it. So show every dose on the label, explain what the product replaces and give people a way to check the result. Hiding the doses asks for blind trust, and doubt is why a lot of them quit.
6. What a routine costs
A small group, so these are plain counts40 people gave a monthly figure. The middle answer was about $50, with 18 people under $50, 13 between $50 and $149, and 9 at $150 or more. Fitness users often count protein powder, so their numbers come out higher. The four biggest spenders, at $400 to $750 a month, all describe long routines for several health problems at once.
"I spend like $40-50 a month on supplements on average."
"10 years ago i was spending about $500 a quarter on supps, now the same order costs over $2k."
"I've been doing this forty years. The last two have been the heaviest, probably $400 a month or more on my habit. But I am starting to figure out what I'm doing. Finally."
What the brief got right, and what it missed
The brief guessed that people cut a stack because of cost, complexity or uncertainty rather than a bad experience, and that held up. 56 of 93, about six in ten. But it didn't give doubt enough weight, because doubt is the biggest single reason, and it comes from not being able to tell if anything works.
What the brief missed is that stopping one product and stopping everything happen in different ways. People drop one product after a bad reaction, often quickly. They stop everything slowly: a missed week, a tight month, or a day when they wonder why they still take all this. A brand that only reads complaints sees the first group and misses the second.
There's one thing I can't answer. Many people who cut everything say they felt better afterwards, and maybe one of the products really was causing a problem. Or maybe they just feel better because they stopped managing ten bottles and worrying about each one. Honestly, I don't know. These comments can't tell those two apart, and I'm not sure any comments could. Our piece on why customers quit argues that losing belief drives more churn than the product does, and these comments point the same way. For a closer look at one product people quit, see the melatonin study. For a format that promises to remove the pill burden, see the wellness patches study.
A customer glossary
The words people actually useThese are the words your customers use about their routines.
| Term | What people mean | Signal |
|---|---|---|
| Stack | Everything someone takes, treated as one routine. Heavy users say it with pride. People trying to cut back say it a little embarrassed. | category |
| Rate my stack | A post listing a full routine and asking for feedback. The replies almost always suggest adding something, rarely removing it. | behaviour |
| The basics | Vitamin D, magnesium, fish oil, creatine and sometimes a multivitamin. What most people keep after a cut. | benefit |
| Expensive pee | The standard joke for a supplement that does nothing because the body doesn't need it. Usually said by people who are about to stop. | objection |
| Culling | Going through the routine and removing things. Often a regular event, followed by the stack growing back. | behaviour |
| Cofactor | Something you take so another supplement works or stays balanced, such as K2 with vitamin D or copper with zinc. One of the main ways a stack grows. | behaviour |
| Cycling | Taking something on and off rather than every day. Part tolerance worry, part an easy way to test if it matters. | behaviour |
| Proprietary blend | A label that lists ingredients without doses. Read as a red flag, especially on all-in-ones and greens powders. | complaint |
| Third-party tested | Independent lab testing of what is in the bottle. The trust signal people ask for most when choosing a brand. | benefit |
| Pill fatigue | Being tired of swallowing a handful of pills every day. Comes up most with people who also take prescription medicine. | complaint |
Frequently asked questions
Why do people stop taking their supplements?
It depends on whether they stop one product or the whole routine. Of 93 people who explained why they cut back several products at once, 56 named money, hassle or doubt that it was working, and no bad reaction. Doubt came up most (43 people), then a bad reaction (28), hassle (24) and cost (23). But when people dropped a single product it was the other way round, and 41 of 70 named a bad reaction.
How many supplements do most people take?
In these comments, most people keep it short. Of 437 people who listed their own routine, 231 named 1 to 3 products, 167 named 4 to 7, and 39 named 8 or more. All of them chose to talk about supplements, so heavy users are probably more common here than in the general public.
Which supplements do people keep when they cut back?
Mostly the same few, because when people were asked which supplement they'd never give up, the top answers were vitamin D (56), magnesium (45), creatine (35) and fish oil (20). Those numbers come from 234 comments that named a product, and people who cut a long routine down usually end up with some mix of these, sometimes with a multivitamin.
What do users think of all-in-one supplements like AG1?
Mostly negative, but the complaints are more about trust and price than about the idea of one product. Out of 112 things people said about all-in-ones and greens powders, about 20% were distrust of the podcasters who sell them and 16% were about price. Another 10% called it an expensive multivitamin and 10% complained about hidden or tiny doses. People did like some things, though: about 11% liked having fewer pills and 11% said they felt it work. Most of these comments are about one brand, AG1.
How much do people spend on supplements each month?
Among 40 people who gave a monthly figure, the middle answer was about $50. Of those 40, 18 spend under $50 a month, 13 spend $50 to $149 and 9 spend $150 or more. Fitness users often count protein powder, so their numbers come out higher, and the biggest spenders ($400 to $750 a month) all describe long routines.
