Gominak's second chapter is the one people screenshot. Raise vitamin D, sleep improves, then some people wobble after a couple of years. Her reading: the bacteria that make B vitamins have thinned, especially pantothenic acid.
The method has two steps, and the second one is the one that usually gets cut. A B50 or B100 for about three months, then a lower daily dose of B vitamins, not a lifetime at 100 mg.
We think that sequence is worth taking seriously. We also sell B vitamins in Europe, as a food. Those two facts pull in different directions, and the law wins on the high-dose stretch.
The short answer
- Some gut bacteria can make B vitamins. Food still supplies them. Both can be true at once.
- Her first stretch is a clinic-scale complex: about 50 or 100 mg of each of eight B vitamins, for around three months.
- Then she wants a lower daily B dose, once that stretch is done. That is part of the method, not an afterthought.
- Biotin is not in our pouch. Count the panel: seven, not eight.
- 100 mg of vitamin B6 is above the adult upper limit EFSA set in 2023. We cannot put the first stretch on a food sold here.
What she is pointing at
The eight B vitamins are B1, B2, B3, B5, B6, biotin, folate and B12. Microbes have been known for decades to make some of them. Gominak's 2016 paper argues that low vitamin D changes which bacteria live in the intestine, and that B vitamin output falls with that change.
A 2018 systematic review in the European Journal of Nutrition found vitamin D and the gut microbiome do seem to talk to each other in animals and in small human studies. The details were messy from paper to paper. Messy is not the same as empty. It is the state of that research.
None of that erases dinner. Eggs, meat, dairy, pulses, grains and leaves are ordinary sources. Europe's reference intakes are built on food. Saying the gut can contribute is not the same as saying a mixed plate does not count. We will not write the second version. Article 3 of the claims regulation is exactly that trap.
Pantothenic acid is in a lot of foods. That is why a mixed diet rarely looks empty of it on paper. Her clinic was not a paper diet. It was people whose sleep and blood work had already gone off. A clinician can work from that. A food label cannot.
Two steps, not one bottle forever
In her method the high-dose complex is a rebuild, not a daily habit for life. B50 and B100 mean about 50 mg or 100 mg of each of the eight B vitamins, for around three months. After that she steps down to a lower daily B dose, on the idea that the gut is making more of its own again.
That second step is closer to how a European daily multinutrient is built: food-scale amounts, every day, not 100 mg of B6. It is still not her protocol, and we will not sell it as a sleep plan.
Why we cannot sell the high-dose stretch
Look at an EU pack.
The adult NRV for pantothenic acid is 6 mg. Pocket Adults carries 100% of that: 6 mg. A B100 at 100 mg of B5 is in another league.
Vitamin B6 is the line that is not a style choice. EFSA's adult upper limit, revised in 2023, is 12 mg a day. A 100 mg B6 tablet is several times that ceiling. High B6 over time is the dose range linked to nerve symptoms. In the US, a clinician may still use a bottle like that. On an EU food supplement, we may not. That is the local rule, not a disagreement with her about B vitamins mattering.
B12 sits in micrograms on both kinds of label. Ours is a high percentage of the adult NRV. That is a different conversation from the milligram B vitamins next to it.
Biotin we do not include. If the method wants all eight, our panel is seven. We would rather you saw that than find it after you bought.
What we would actually do in a European cupboard
Amounts add. If a daily multinutrient is already in the house, a B100 on top is a second, much larger dose of B6, B3 and B5. That is the opposite of her step-down.
The pouch was built as a daily food for a household, inside European upper limits, without biotin, without iron. That puts it in the same shape as her lower-dose phase: an ordinary daily B intake, not a three-month rebuild. It was not built as either half of a US clinic sleep protocol, and we will not market it as one.
If a clinician here has named a high-dose B complex for a short stretch, that is their product, not ours. Take the labels in. Ask them to add the B6. When they step you down, stay inside the dose they set. Do not keep the 100 mg running because the first bottle is not empty.
What we can sell, and say, is more modest: each of several B vitamins in the formula contributes to normal energy-yielding metabolism, and each contributes to the reduction of tiredness and fatigue, in those exact words. That is the register. It is not sleep, and we will not stretch it.
