About Dosera
For everyone who was told to "keep an eye on it."
Prediabetes, PCOS, burning feet, the sweet tooth that wins after dinner. Dosera makes five products for those five problems, at the doses the studies used, with nothing padding the capsule.

The story
It started with a bottle that said 1,200 mg and meant 400.
It started the way it starts for most people. An A1c of 6.1, a doctor saying "let’s keep an eye on it," and a bottle of berberine from Amazon with four thousand good reviews. The front said 1,200 mg. The back, in small print, said 400 mg per capsule, one a day, in a blend. Three months, nothing.
That is how most people give up on an ingredient that works. Berberine has more human studies for blood sugar than any plant there is. Ceylon cinnamon, inositol, alpha-lipoic acid and gymnema each have their own. Every one of those studies used a set dose, and almost nothing on the shelf matches it.
Dosera was built to fix that one thing: the full study dose, split so it sits well, with nothing else in the capsule. Inositol at the 40:1 the PCOS forums look for. Alpha-lipoic acid at 600 mg. Ceylon cinnamon, never the cassia from the spice aisle.
An outside lab checks every batch for strength, lead and heavy metals, and the sheet is on the bottle to scan. The name comes from "dose", because that was the one thing wrong with every bottle before it.
One bottle is one month. Finish it, and if nothing changed, every cent comes back without shipping anything.
