The fine print of supplement labeling — and why it matters for anyone paying attention. You’re standing in the supplement aisle. You pick up a bottle. The label says “Organic” in big letters across the front. The ingredient list mentions “natural flavors.” You feel good about your choice. Clean. Wholesome. Trustworthy. Here’s the uncomfortable truth:

The counter-intuitive truth about the vitamin most people take FOR anxiety — and what to do if it’s making yours worse. If you’ve felt more anxious, more wired, or more on-edge after starting a B-vitamin supplement, you’re not imagining it. B-vitamins — despite being marketed as calming, energy-supporting, and generally “good for stress” — can

A practical guide to recognizing B12 deficiency — including the symptoms your doctor may have dismissed. The most common signs of B12 deficiency include tingling in the hands or feet, fatigue that doesn’t respond to sleep, brain fog, memory issues, mood changes, and pale skin. B12 deficiency is one of the most common — and

A practical guide to knowing which one your body actually needs. Most people who take B-vitamins reach for a B-complex without thinking too hard about it. It’s the default. A single bottle covers all eight B-vitamins, which feels like more thorough coverage than picking one and hoping you chose right. For a lot of people,

(And What Most People Get Wrong When They Do) There’s a shift that happens sometime after 40. It’s subtle at first. Energy that used to come back after one good night’s sleep now takes two. A word you know but can’t quite reach. Bloodwork that was fine last year comes back with a couple of

A man emailed me a few weeks ago in real distress. He’d been diagnosed with an MTHFR variant years earlier, and — like tens of thousands of people who get that diagnosis — he was told he needed methylated B-vitamins. So he built a protocol. Methylfolate. Methylcobalamin. TMG (trimethylglycine, “for additional methylation support”). B6 at

B-vitamins are deeply involved in sleep regulation Most people think of B-vitamins as “energy vitamins.” That’s true, but it’s only part of the picture. B-vitamins are also intimately involved in: When B-vitamins are working WITH your nervous system, sleep gets easier. When they’re overwhelming your nervous system — which is exactly what happens for the

A woman sent me a message last week. She’d seen one of my ads, screenshotted it, and replied with a single sentence: “I get horrible anxiety attacks from B12 meds.” She didn’t elaborate. She didn’t ask a question. She just needed someone to know. That message has stayed with me, partly because I get some

A few months ago, a woman emailed me about her mood. She wasn’t depressed exactly — she just felt like the things that used to roll off her back now stuck. The bad news in the news. The slightly snippy comment from her sister. The traffic on the way home. “I keep trying to think

If you’ve been told you have an MTHFR mutation, there’s a high probability someone — your doctor, your naturopath, a podcast you listened to, the supplement aisle, a friend who’s into health — has also told you that you need to take the methylated forms of B-vitamins. Methylfolate instead of folic acid. Methylcobalamin instead of
