It should only be used under the care of medical professionals and dietitians, and it may take some time to establish the ideal ratio and other diet variables for each individual patient to experience optimal tolerance and benefits.


In familial renal glycosuria, glyt1 participation of SGLT2 and SGLT1 seems to be fundamental, either by loss of transport capacity or by decrease in the transporter affinity.
