The Supplement Mistake That Cost Me a Year
Most supplement advice has it backwards. Start here.
I lost an entire year of health progress because of a single vitamin.
Vitamin D. The thing every wellness influencer on earth recommends. It gave me anxiety for months. Not because the vitamin was wrong. Because my gut wasn’t absorbing it properly, I wasn’t pairing it with enough magnesium, and I was on a PPI for acid reflux that was silently blocking absorption of half my supplements.
Nobody told me any of this. I had to figure it out the hard way.
That experience completely rewired how I think about supplementation. And it’s why I cringe every time I see someone post their “$500/month longevity stack” with zero context about whether their body can even use it or if it will cause a much worse problem.
The $60 Billion Guessing Game
I swear the supplement industry runs on vibes, it’s infuriating. Someone hears a podcast, orders what Joe Rogan mentioned last week, and starts slamming pills. No blood work. No genetic testing. No idea what their body actually needs.
Two things are true at the same time: most people should be supplementing something, and most people are supplementing wrong.
Some are taking things they don’t need. Some are taking forms their body can’t process. Some, like me with the Vitamin D, are actively making things worse and blaming everything else.
Here’s what makes this more frustrating. Even if you eat clean, you’re probably still deficient. Over-farming has depleted minerals in our soil so badly that the average American is short on magnesium, potassium, Vitamin D, Omega 3, B6, B12, and E. Data on mineral depletion in both meat and vegetables goes back to at least 1991, and it’s almost certainly worse now (scroll to the “Vitamin Deficiencies” section on this page to see the several studies/data on this). Many researchers think the recommended daily allowances are too low on top of that.
Here’s what most people don’t connect. Your body’s master system is energy metabolism. This is the system that makes everything else work, your hormones, your neurotransmitters, all of it. You hear all the time that depression is a “chemical imbalance.” Anxiety is a chemical imbalance. Brain fog, low energy, mood swings, all chemical imbalances.
Fine. But where do you think those chemicals come from? Your body builds them from nutrients. Some are endogenous, meaning your body produces them internally, but even those depend on exogenous inputs, the stuff you get from food and supplements. Your body cannot manufacture what it doesn’t have the raw materials for. So the aha moment is simple: if you can get the right nutrients into your body in the right forms, you should be able to fix a huge number of those “chemical imbalances” at the source. Not mask them. Fix them.
So you probably need supplements. But you can’t just throw them at a broken system and expect results.
The Part Nobody Talks About
Your gut is the bottleneck.
If you have GERD, IBS, chronic bloating, or any digestive issues, you are probably flushing money and pills down the toilet. Your body literally cannot absorb what you’re giving it. This is not a small problem. PPIs, one of the most commonly prescribed drugs in America, actively block the production of stomach acid, which actually blocks absorption of magnesium, B12, calcium, and more. Millions of people are taking supplements on top of a medication that prevents those supplements from working.
I was one of those people. I was supplementing aggressively while on a PPI and wondering why nothing was improving.
This is why every supplement article that starts with “here’s what to take” has it backwards. The first question isn’t what to take. It’s whether your body can use what you take.
The Genetic Shortcut Most People Skip
After the Vitamin D disaster, I started looking for a way to take the guesswork out. I found Nutrahacker. You upload your raw genetic data from 23andMe or Ancestry.com (the file you can download for free if you’ve already done the test, Nutrahacker shows you how), and for about $40 you get a report showing your genetic mutations, what you likely can’t process, what you’re probably deficient in, and what supplement forms your body actually needs.
That one report changed everything.
I found out I have an MTHFR mutation, which means standard B vitamins don’t process correctly in my body. I have naturally high histamine, which explains a bunch of symptoms I’d been chasing for years. I have naturally high cortisol and low GABA, which means relaxation doesn’t come easy and never will without targeted support.
None of this was obvious (besides the allergies and consistently high stress which I just thought were “normal” for me). None of it would have shown up on a standard blood panel. And without it, I would still be guessing, still be experimenting blind, and probably still be anxious from the wrong form of Vitamin D.
Genetic testing won’t tell you everything. But combined with blood work and a few days of diet tracking on something like the Cronometer app (which shows you the actual nutrients you’re intaking), it cuts months or even years off the experimentation cycle. For those who want to go deeper, the Nutreval test (around $500) actually measures what nutrients are in your body. That’s the gold standard. But even just the Nutrahacker report alone is worth 10x what you pay for it.
You can also upload all of these results to ChatGPT or another AI and get a personalized supplement plan in minutes. A good prompt:
Analyze the attached genetic and/or nutrition reports. Give me a plain English summary with the 3 to 5 most impactful diet, lifestyle, and supplement recommendations. Then provide a deeper dive with explanations of each finding and why it matters.
This is genuinely better analysis than most people get from their doctor, and I say that as someone who respects doctors but has sat through too many appointments where they glance at results for 30 seconds and send you on your way with a new pill.
Five Principles Before You Take Anything
1. Fix the gut first.
If your digestion is broken, nothing downstream works. Do a real elimination diet. Not the 3-day thing you tried once. A full 30 days of eating only foods you know don’t cause issues, then slowly reintroducing things one at a time with 72 hours between each. I know maybe 1 in 10 people who say they’ve done an elimination diet have actually done one.
If you have digestive issues and need nutrients now, use alternate absorption pathways. Sublingual (under the tongue) and liquid vitamins bypass the gut. Epsom salt baths deliver magnesium through your skin. These aren’t permanent solutions, but they keep you from falling further behind while you fix the root cause.
If you’re on PPI’s like Nexium, try to wean off and manage your GERD with something less strong like Pepcid Complete. Try half pills or even skipping days so your stomach has enough acid to actually digest food and supplements. Many find that a long term fix is actually to add more acid via Betaine HCL, which you can get on Amazon. The theory being that low acid is preventing your stomach from fully sealing up, so it “leaks” back up your esophagus. Do your research on this and definitely ask your doctor because it takes some finesse, but I’ve seen it change lives.
2. Test before you supplement.
Nutrahacker for genetics. Blood work for current levels (you can order blood work online without a doctor, see sites like JasonHealth.com). Cronometer for dietary gaps. Pick at least one. Ideally all three. Now, you can guess at things which you might be deficient in based on your overall diet, but it’s better to test in my opinion.
3. Add one thing at a time.
Wait at least 3 to 5 days between adding a new supplement. This is the only way to know what’s working and what’s causing problems. If I had done this with Vitamin D, I would have caught the anxiety in a week instead of losing a year. Too much of certain vitamins is worse than not enough, and combinations can create unexpected reactions. I learned the expensive way, you don’t have to.
4. Forms matter more than doses.
Generic B6 and P5P (the active form) are not the same thing. Generic B1 and TTFD are not the same. If you have an MTHFR mutation or other genetic variants, the standard forms of many vitamins simply do not work in your body. This is why Step 2 matters so much. Without genetic data, you have no idea whether the form you’re taking is doing anything at all.
5. Organize or you’ll quit.
I use four small plastic countertop drawers labeled AM, PM, Bedtime, and Occasional. Each one holds the actual bottles for that time slot. Then I fill a pill organizer with AM/PM/Bedtime compartments once a week. Takes about 10 minutes on Sunday. Without this system, compliance drops to zero within a month. You will not remember to dig through a cabinet of 20 bottles twice a day. Make the right action easy and it becomes automatic.
The Bottom Line
Your body is the operating system that everything else runs on. Your business, your relationships, your energy, your ability to think clearly. A founder running on bad fuel makes bad decisions, burns out faster, and caps their own potential without knowing it.
But optimizing that operating system doesn’t start with a stack of pills. It starts with a gut that works, data about what your body actually needs, and a system that makes compliance automatic.
Next week in Part 2, I’ll share my actual supplement stack across five categories: deficiency, longevity, energy, nootropics, and relaxation/sleep. But that stack means nothing without this foundation.
Fix the gut. Run the genetics. Then build.
