Supplement & Fasting Mistakes I Made at 60

D Dr. LongHeart July 23, 2026

I turned sixty this year. If I lined up every supplement I've bought since my thirties, the bottles would cover a kitchen table, and half of them would be nearly full. I did the cleanses. I skipped breakfast for years at a stretch, sure I was starving my cells young. Thirty years of earnest, well-read, well-meaning experimenting.

Here's the uncomfortable part. Most of it didn't do what I was promised. And the small handful of things that genuinely helped turned out to be the plain, unglamorous ones I kept stepping over on my way to the exciting stuff. I'm not writing this to sell you my regret. I've spent a career in medical science teaching mechanisms, and I wish someone had handed me the plain version thirty years earlier. So here it is, without the marketing.

Lesson One: Most Supplements Are Not Magic, and That's Fine

For years I treated the supplement aisle like a menu of upgrades. Cognition here, longevity there, one more capsule for the mitochondria. What finally changed my mind wasn't a bad experience. It was reading what happens when you test these things carefully, at scale, in ordinary healthy people.

The most sober summary we have comes from the group that reviews prevention evidence for a living. After weighing the trials, they concluded there simply isn't good evidence that multivitamins or most single supplements lower the odds of heart disease or cancer in generally healthy adults, and they recommend against two old favorites, beta-carotene and vitamin E, outright (US Preventive Services Task Force, 2022; PubMed).

That doesn't make supplements useless. It means the framing is wrong. A supplement is a tool for a specific gap, not a general upgrade. If a blood test shows you're low in vitamin D or B12, replacing what's missing is genuinely useful, which is the case I make in the vitamin D "600 IU" math. Taking twelve things on a hunch because a podcast host does is not. The rule I landed on, decades late: test, don't guess, and let food be the default and the pill the exception.

Lesson Two: The "Detox" Was the Myth I Fell Hardest For

Detoxes were my weakness. Juice weeks, cleanse teas, the whole ritual of "resetting." They felt virtuous, and I always finished a few pounds lighter, which I took as proof.

It wasn't proof. It was water and an empty gut. Here is the part the cleanse industry would rather you not sit with: your body is not a clogged drain waiting for a product. It runs a full-time detoxification system already, and your liver and kidneys do the bulk of the work, clearing what needs clearing through urine, stool, sweat, and breath (National Center for Complementary and Integrative Health, NIH).

And the commercial cleanses layered on top of that system? When researchers went looking for solid human trials showing detox diets remove toxins or deliver lasting benefit, they found essentially none. The reviews are blunt: the studies aren't there, and most products never even name the "toxin" they claim to remove (Klein and Kiat, 2015; PubMed).

So I'll say it plainly, because I earned it the hard way. "Detox" as a purchasable cleanse is a myth. The real detox is the quiet organ work already happening while you sleep. The best thing you can do for it isn't tea. It's not overloading it, sleeping enough, and keeping your circulation moving so those organs stay well supplied.

Lesson Three: Fasting Helped a Little, Mostly for Reasons I Didn't Expect

Intermittent fasting was the one I wanted to be the answer. For a long stretch I ate only in an eight-hour window and felt clever about it.

Some of it was real. I ate less junk at midnight because the kitchen was "closed." But when I finally looked at the controlled research instead of the enthusiasm, the picture got humbler. In one careful randomized trial, people assigned to a 16:8 time-restricted schedule lost no more weight than people eating on a normal schedule over twelve weeks (Lowe and colleagues, 2020; PubMed).

The evidence overall is genuinely mixed. Fasting isn't fake, and some people find the structure helps them eat more sensibly. But it's a scheduling tactic, not a metabolic magic trick, and for some people, including anyone with a history of disordered eating or certain health conditions, it's the wrong tool entirely. If you have a health condition, check with your doctor before you try fasting, especially at sixty. What fasting mostly did for me was strip out mindless late eating. I could have gotten that with a simple rule and no dogma.

Picture your day as a single line. For part of it the kitchen is closed; for part of it you eat. A fat-soluble supplement has an obvious best moment on that line: alongside food, in the eating window, where a little fat helps it absorb. The diagram below lays the day out and marks where a supplement actually lands, so the timing stops being guesswork.

What Actually Moved the Needle

Here's the part that stings a little, because it's so ordinary. When I look back plainly, the changes that improved how I feel at sixty weren't in any bottle. They were the things I dismissed for decades as too boring to count.

The people who study heart and circulation health for a living now organize the whole picture around eight basics, and the loudest ones are exactly the plain ones: eat mostly real food, move your body regularly, sleep enough, don't smoke (Lloyd-Jones and colleagues, 2022; PubMed). Sleep, in fact, was only formally added to that checklist recently, which tells you how long even the experts underrated the boring stuff.

There's a circulation thread running under all of it, and it's the one I care about most now. Your muscles, moved regularly, keep your smallest blood vessels, the capillaries, open and busy, and the daily movement and metabolism story after 40 is really the same thread starting earlier. Real food and steady sleep feed and repair that same network. This is what the idea of your vascular age is really pointing at: not your birthday, but how well-kept your circulation is. A body that's fed, rested, and moved often behaves younger than the calendar. That isn't a supplement claim. It's just what thirty years of doing it the hard way finally taught me.

What I'd Tell My Younger Self

Not a program. Just the short list I'd hand a thirty-year-old me:

Food is the default; the pill is the exception. Fix a tested deficiency, don't chase a dozen hunches. Most of the money I spent on supplements bought me expensive urine.
Skip the "detox." Support the one you already own: sleep, don't overload it, keep moving. Your liver and kidneys don't need a tea.
If you fast, count it as a schedule, not a fix. And drop it the moment it makes food stressful rather than simpler.
Move most days, gently and often. A daily walk turned out to be steadier for me than any capsule. Consistency beat intensity every time.
Guard your sleep as carefully as anything else. It's the closest thing to a real reset I ever found, and it's free.

None of this is a medical verdict and none of it is a fix. If something feels new, severe, or wrong, that's a conversation for your own doctor, not a blog and not a supplement shelf.

The One Habit I Wish I'd Started at Thirty

Of everything on that thirty-year list, daily movement is the one that quietly did the most, and the one your circulation answers to fastest. Knowing that is one thing. Knowing where your circulation stands, and which plain habit to start with, is what makes it real.

That's exactly what our quick "What's Your Vascular Age?" assessment is built for. Answer a short set of questions about your daily life and circulation habits, and you'll get a motivational vascular-age estimate plus a starting point tailored to where you are. It's an educational guide, not a medical test, and it's the front door to our free Movement & Energy guide, a simple at-home routine built around the basics above.

Frequently asked questions

What are the most common supplement and fasting mistakes?

The three big ones are treating supplements as a general upgrade instead of a fix for a tested gap, falling for purchasable detoxes, and expecting fasting to be a metabolic magic trick. The plain basics I kept skipping, real food, movement, and sleep, did far more than anything in a bottle.

Should I take supplements while fasting?

It depends on why you are fasting and what the supplement is. If a blood test flagged a real gap, replacing what is missing is reasonable on any schedule, and some are gentler with a little food. For anything tied to a health condition, check with your doctor rather than a blog.

Does taking a supplement break a fast?

For most plain fasting goals, a calorie-free capsule of water-soluble vitamins is unlikely to matter much. The ones people worry about are those with real calories, sugar, or oil, which give the body something to process. But the useful question is not the capsule, it is what you are actually fasting for.

What are the best supplements to take while fasting?

The plain, boring answer: the ones that fix a documented deficiency, and no more. There is no universal fasting stack the evidence endorses. Water, and being sensible about electrolytes on longer fasts, does more than a cabinet of capsules, and none of it substitutes for real food when you are eating.

Is fasting worth it after 60?

For some it is a useful way to cut mindless late-night eating; for others, especially anyone with a history of disordered eating or a medical condition, it is the wrong tool. It is a scheduling tactic, not a longevity trick. If you are weighing it at sixty, have that conversation with your own doctor first.
