Abstract
Among others, the present invention provides low-lead and low-arsenic beta-hydroxybutyrate (BHB) salts, comprising lead ranging from 10 to 50 parts per billion (ppb) and arsenic ranging from 10 to 150 ppb. The present invention also provides methods for preparing low-lead and low-arsenic beta-hydroxybutyrate (BHB) salts, which may include (a) synthesizing, (b) adsorbing (e.g., by adsorbent and solvent), (c) concentrating under reduced pressure, and (d) spray drying.
Claims28
A beta-hydroxybutyrate (BHB) salt, comprising low lead and arsenic contents, wherein the level of lead ranges from 10 to 50 parts per billion (ppb), and the level of arsenic ranges from 10 to 150 ppb.
A method for preparing beta-hydroxybutyrate (BHB) salt, comprising an adsorbing process for controlling and enabling low levels of lead and arsenic in the prepared BHB salt.
