I-Beta-hydroxy-beta-methylbutyric acid (HMB) ifumaneka ngokubanzi kwiziqhamo ze-citrus, imifuno ethile efana ne-broccoli, i-legumes efana ne-alfalfa, kunye neentlanzi ezithile kunye nokutya kwaselwandle. I-Beta-hydroxy-beta-methylbutyric acid (HMB), njenge-metabolite ye-leucine, ibonakaliswe ukwandisa i-muscle synthesis, ukunciphisa ukuphuka kwemisipha, kunye nemiphumo echasayo. Ukuguqulwa kwe-HMB kwi-stable β-hydroxy-β-methylbutyrate calcium salt (HMB-CA) isetyenziswe ngokubanzi kwisondlo sezemidlalo kunye nokunye ukutya, okunokudlala indima ekhethekileyo yesondlo:

I-1, esetyenziselwa ukukhuthaza ukukhula kwemisipha, ukuphucula ukukhuseleka, ukunciphisa izinga le-cholesterol kunye ne-low-density lipoprotein (LDL) emzimbeni ukunciphisa ukuvela kwesifo senhliziyo kunye nesifo senhliziyo, kodwa kunye nokuphucula amandla okulungiswa kwe-nitrogen, ukugcina amanqanaba eprotheni emzimbeni;

I-2, inokongezwa kwiziphuzo, ubisi kunye neemveliso zobisi, iimveliso ze-cocoa, i-tshokoleta kunye neemveliso zetshokolethi, i-candy, izinto ezibhakiweyo, ukutya okukhethekileyo kokutya, isixa esicetyiswayo sise-≤3 g / ngosuku; I-3, i-United States yoKutya kunye noLawulo lweDrugs ye-GRAS ukuqatshelwa, umda wokusetyenziswa kokutya kwezonyango kunye nezidlo ezikhethekileyo. Ngokutsho kweThebhile 2 kunye neThebhile 3 yaseChina "Imithetho Jikelele yeZondlo zeMidlalo Ukutya koMgangatho weSizwe woKhuseleko lokuTya" (GB 24154-2015), i-1-3 g / ngosuku inokongezwa kwimveliso yezondlo zezemidlalo zesantya kunye namandla.
