One preparation,
ten buyer’s guides

There is one Bacillus F preparation: the same applicator, the same daily dose. People come to it for different reasons: as an antioxidant, for DNA repair, for immunity, as an alternative to a probiotic. Each of these ten guides takes one of those reasons seriously and ends at the same applicator.

How to use these guides: all ten describe the same preparation. What differs is the question each one answers and the marker it suggests you track. If you’re new, begin with the Postbiotic Supplement and read the Bacillus F vs NMN comparison. If you already run a longevity stack, jump straight to the category matching the marker you track. Every guide carries the same evidence, patents, genome deposit, comet-assay imaging, and points to the same product, shipped in the same small monthly batches.

Choosing between them

Everything. They describe one preparation: the stable metabolite complex of the Bacillus F strain, two presses a day. What changes from guide to guide is the question it answers and the marker it suggests you track.

The Postbiotic Supplement. It is the flagship, the reference protocol, and the one all our published documentation describes. The other guides are the same product, read through a different question.

Yes. Different mechanisms. NMN targets NAD+, spermidine targets autophagy, Bacillus F targets oxidative-stress defense. Our Learn guides cover the exact stacking logic.

Yes. Every bottle is the same postbiotic preparation from the same patented, sequenced organism. The guides differ in the goal they are framed around, not in what is in the bottle.
