my advice is to not use any insulin mimicking or insulin effecting suppliments while taking insulin
by that i mean at the exact same time
if you are taking slin 4 days a week on the off days you could take ala but on the days you take insulin dont do it
the interaction of slin and these suppliments are unknown and if you are taking insulin you really dont need them anyway
recap
you can take insulin mimicking substances while on an insulin cycle as long as it is not on the same day as an insulin injection but i dont think it is needed... save it for when you are not using slin. 16 hours after last shot should be safe for supplimentation or 16 hours after last supplimentation should be safe for slin injection
