Origin and Existence of HMB-Ca

The sources and forms of HMB Ca (β - hydroxy - β - methylbutyrate calcium) are as follows:

1、 Natural sources (in the form of HMB)

Plant derived sources:

Citrus fruits: such as oranges, pomelos, etc.

Vegetables: such as cauliflower.

Leguminous plants: such as purple clover.

Animal origin:

Certain fish and seafood products.

2、 Endogenous synthesis in the human body

HMB (β - hydroxy - β - methylbutyric acid) is a natural metabolite of the essential amino acid leucine in the body.

The human body can only produce a small amount of HMB on its own, with an adult weighing 70 kilograms producing approximately 0.2-0.4 grams per day.

3、 Artificially synthesized form (HMB Ca)

Due to the active nature of naturally occurring HMB, synthetic methods are used in industrial production to convert HMB into its calcium salt form, namely β - hydroxy - β - methylbutanoate calcium (HMB Ca), for stability and ease of application (such as as as as food additives and dietary supplements).

HMB Ca is a white powder that is easily soluble in water and is a common form of HMB supplement in the market.

Summary: HMB naturally exists in various foods (citrus fruits, cauliflower, alfalfa, certain fish) and in the human body (leucine metabolites). HMB Ca is mainly a stable calcium salt form obtained by artificially synthesizing and transforming its precursor HMB, which is used for commercial applications
