The Wise Intake Letter
Supplement industry insights from someone who actually works inside it. No sponsorships. No fluff. No agenda.
A weekly email that tells you what the supplement industry prefers you didn’t know.
Most supplement content online is written by people who are paid — directly or indirectly — to say certain things. Affiliate codes, brand partnerships, sponsored posts, free products in exchange for reviews. The incentives are everywhere, and they shape what gets said.
The Wise Intake Letter is written by someone who works inside the industry with no financial stake in what you buy. Every week, one honest email about supplements, nutrition, and what’s actually worth your attention.
“The gap between what the industry knows and what consumers are told is enormous. I decided to start closing it — one email at a time.”
Here’s what a typical email looks like.
One topic, explored properly. No filler, no padding. Read in under five minutes.
If I could look at one thing on your supplement shelf and make a single swap, it would almost always be the same thing: your B12.
Most B12 supplements — including those in multivitamins — use a form called cyanocobalamin. It’s cheap, stable, and widely used. It’s also a form your body has to convert before it can use it, and that conversion process requires a functioning methylation pathway. Roughly 40% of people have a genetic variant that makes this conversion inefficient.
The alternative is methylcobalamin — the active form. Your body can use it directly, without conversion. It costs a little more. The difference in how people feel when they switch is often significant enough that they notice it within a few weeks.
Pick up your multivitamin or B12 supplement. Find the B12 entry in the ingredients. It will say either “cyanocobalamin” or “methylcobalamin.” If it says cyanocobalamin — you now know what to replace it with. If it says methylcobalamin — you’ve already made a good choice. Either way, you’re reading the label. That’s where it starts.
One of my four has started sitting directly on the food storage containers. I choose to interpret this as quality control rather than disruption. We are working on it.
