Is HealFast safe?

Yes - HealFast is designed to safely optimize recovery in the peri-operative period and be used alongside anesthesia and pain meds while minimizing interactions with common drugs, other ingredients, and peri-operative events. 

In fact, HealFast has omitted certain vitamins contained in typical supplement programs if they have even the slight potential to interact with medications generally consumed during the operative period (e.g., Vitamin E).
