More signs coming this week. Follow so you don't miss them.

A few years ago, a woman reached out to me about something that seemed almost too small to bring up. The corners of her mouth kept cracking. Not painful, not constant — just always a little raw, always a little sore. She’d been treating it with chapstick and antibiotic ointment for over a year.

Nothing was working, because chapstick wasn’t the answer.

That little crack at the corner of her mouth had a name — angular cheilitis — and it’s one of the most well-documented signs of low B2 (riboflavin). Once she started replenishing her B-vitamins, it cleared up in about three weeks.

That story stuck with me because of how easy it is to miss these signs. When most people think about B-vitamin deficiency, they think fatigue — and they’re not wrong. But by the time you’re dragging yourself through the day, your body has usually been waving smaller flags for months.

B-vitamins are involved in almost every energy-producing reaction in the body. They help turn the food you eat into usable fuel, build new cells, transport oxygen, run your nervous system, and keep your mood and focus stable. There are eight of them, and they work as a team — which is why a shortage of one usually shows up in more than one place.

If you suspect you’re in the methyl-sensitive group, here’s what to look for on a supplement label:

Non-methylated forms to look for:

Folate as folic acid (not methylfolate, L-methylfolate, or 5-MTHF)

B12 as cyanocobalamin or hydroxocobalamin (not methylcobalamin)

B6 as pyridoxine HCl (not P-5-P or pyridoxal-5-phosphate)

B3 as niacinamide (the non-flushing form)

Things to avoid if you’re methyl-sensitive:

Methylated B-vitamins in any form (above)

Mega-doses — anything over about 500% of the daily value for any B-vitamin. More isn’t better; for sensitive systems, more is worse.

Capsules with a long ingredient list of “other ingredients” — common fillers like magnesium stearate and cellulose can also be triggers for sensitive folks

In my own line at Herb-Science, every B-vitamin is non-methylated, every dose is kept at 500% DV or lower, and they’re all delivered as liquids so you can adjust your dose drop by drop instead of being stuck with whatever’s in the capsule.

If you’ve experienced any of these after taking a B-complex, you might be in the methyl-sensitive group:

Feeling more anxious instead of more energized

Racing thoughts or feeling “wired”

Trouble falling asleep or staying asleep

Irritability that doesn’t match the situation

Heart palpitations or a feeling that your heart is racing

Headaches within a few hours of taking it

Feeling overstimulated, like you’ve had too much caffeine

Some people get one or two of these. Some get the whole list. The most common pattern is taking a supplement in the morning and feeling “off” all day without being able to point to why.

I’ve talked to people who have spent years trying to figure this out — switching brands, lowering doses, taking it at night instead of morning, splitting capsules. Most never realize the issue is the form, not the timing or the dose.

When methylated B-vitamins became the trend in the supplement world over the last few years, I genuinely considered switching my product line. Big names in wellness were saying methylated forms were superior. Some were even claiming non-methylated forms were dangerous. The pressure to keep up was real.

But after the phone call I mentioned, and after trying methylated B-vitamins myself and feeling the anxiety firsthand, I stepped back and read the actual research instead of the marketing.

Here’s what I found:

Both forms have a place. Some people methylate slowly and benefit from pre-converted forms. Some people methylate just fine and do better with the standard non-methylated forms. The “methylated is always better” claim is marketing, not science. The “non-methylated is dangerous” claim is even further off — it’s mostly invented for the purpose of selling the methylated version.

So I decided not to chase the trend. Herb-Science makes non-methylated B-vitamins because that’s what I grew up on, that’s what my father (an herbalist) always took, and that’s what works for the 1 in 3 people the methylated push leaves behind.

About 1 in 3 people have the opposite problem. Their methylation isn’t slow — it’s already running at maximum. They have variants like COMT slow or MAOA slow, or they’re just generally what people call “highly sensitive.”

For someone in that group, a methylated B-vitamin doesn’t help. It floods an already-busy system with more methyl donors than it can handle. The result is what most people describe as feeling “wired” — anxiety, racing thoughts, jittery, can’t sit still, can’t sleep. Some people get heart palpitations. Some, like the woman who called me, feel angry instead of anxious.

These reactions usually show up within 30 minutes to a few hours of taking the supplement. They can last most of the day. And the kicker is, most people who experience them never connect the dots back to the B-complex. They blame stress, hormones, caffeine, whatever else is in their life. They might switch to a different B-complex brand and have the same problem, because the issue isn’t the brand — it’s the methylated forms.

Methylation is a chemical process your body does roughly a billion times every second. It’s how your body activates vitamins, manages neurotransmitters, repairs DNA, and regulates mood. It runs in the background, all day, every day, whether you think about it or not.

Most B-vitamins in food come in what I’d call “pre-methylation” forms. Your body has to convert them into their active forms before it can actually use them. For most people, this conversion happens just fine.

But here’s where it gets interesting: about 40 to 60 percent of the population has a genetic variant called MTHFR that slows down that conversion. The supplement industry’s answer to that was to pre-convert the vitamins for you and sell “methylated” forms — methylfolate, methylcobalamin, P-5-P. For people whose conversion is slow, these can be genuinely helpful.

What the supplement industry doesn’t talk about is the other side of the spectrum.

A woman called me a few months ago. She said when she started taking methylated B12, she felt angry. Not anxious — angry. She'd never felt that way before.

She switched to the non-methylated B12 I've sold for years. The anger stopped. The energy stayed.

That phone call kept me from making a big mistake.

I grew up with an herbalist father — that's where my health knowledge started. He always took non-methylated vitamins, and so did I. When I built Herb-Science, that's what we sold.

Then methylated vitamins started showing up everywhere. Big names in wellness started saying methylated forms were superior — some even claimed non-methylated forms (like folic acid) were "bad for you." I almost reformulated to keep up. I even tried methylated B-vitamins myself to see what the fuss was about.
I felt anxious for hours.

So I stepped out of the noise and read the actual research. Here's what's true: some people DO methylate slowly and benefit from pre-converted forms. But not everyone — and the claim that non-methylated forms are dangerous is wrong. Folic acid fortification has prevented countless birth defects in countries that adopted it. The science is solid.

About 1 in 3 people don't do well on methylated B-vitamins. They feel anxious, jittery, angry, wired. Most never figure out it's the supplement.

I decided to stay focused on serving those people instead of chasing the trend.
If you've reacted badly to "premium" B-vitamins, the quiz in our bio can help you figure out where you fall on the spectrum. 60 seconds.

If you regularly take B-vitamins, you've probably heard of methylated forms. Many companies have switched to them based on research showing that about 40% of the population has a gene variant that makes it harder to convert B-vitamins to their active form. For that group, methylated forms can be helpful.

But what works for 40% of people doesn't necessarily work for everyone else. In fact, research suggests about 1 in 3 people are over-stimulated by methylated B-vitamins — they feel more anxious, more wired, and worse overall after taking them.

B-vitamins are essential for thousands of chemical reactions in the body — digestion, energy production, neurotransmitter balance. But the right form matters. In the wrong form for your body, B-vitamins can overstimulate the nervous system instead of supporting it.

I built a 60-second quiz to help you figure out which form is likely a better fit for your body... Link in bio.

This is one of the most common things people overlook.

Here's how energy production actually works inside your body:

Your mitochondria — the tiny energy factories inside every cell — convert nutrients and oxygen into ATP, the fuel your body runs on. But nutrients have to pass through your cell membrane first.

Research suggests that the balance of fatty acids in your diet directly affects how fluid and responsive that membrane is. When your diet is high in omega-6 fats from processed oils and low in omega-3s, the membrane can become less efficient — meaning nutrients struggle to get in and waste struggles to get out.

The result? Fatigue. Even when everything else looks fine.

This is the part almost nobody talks about — and it's often the missing piece.

Your body already knows how to produce energy. Sometimes it just needs the right conditions to do it.
