BHB calcium, chemically 3-Hydroxybutanoic acid calcium salt (CAS 586976-56-9), is the calcium salt of β-hydroxybutyric acid, a ketone body.
As a leading exogenous ketone supplement ingredient, it is used by keto brands and contract manufacturers in powders, capsules and ready-to-drink beverages designed to support nutritional ketosis, mental clarity and fasted exercise performance. KEEP INGREDIENTS supplies BHB calcium bulk powder standardized to ≥98% assay by HPLC, produced through a clean biological fermentation process — free of animal-derived, cell-culture or GMO materials.
Our BHB raw material is a white crystalline powder (100–325 mesh) with a low impurity profile, suitable for ketone salt blends, keto electrolytes, stick-pack ketone drinks and hard capsules. Every order ships with a lot-specific BHB COA tested to USP 34 standards.

What Is BHB Calcium Used For?
β-Hydroxybutyrate is the most abundant circulating ketone body. As a keto supplement ingredient, our BHB calcium is commonly formulated into:
• Exogenous ketone drinks and ketone salt blends • Keto diet powders, capsules and gummies • Fasted exercise and endurance performance products • Mental clarity and focus nootropic blends • Multi-ketone salt stacks (with sodium and magnesium BHB)
Our fermentation-derived BHB calcium powder delivers consistent ketone-body content and avoids the animal-source variability that buyers see in lower-grade synthetic routes.
