Sis, hindi ko sure ng exact na composition ng both kaya mas safe na tanungin mo talaga ang doc or pharmacist mo about taking them together, sometimes may interactions na hindi obvious, lalo na if may medical reason ka for the reducol. Between the two brands kasi, depende lang sa preference mo ng lasa and kung ano ang better sa tummy mo, pero the reducol + juice combo itself is the question na kailangan ng professional opinion talaga! Better safe than sorry, especially pag may health concern ka na behind the reducol, di ba?
