My 14 year old son is loving Absorb plus (unsweetened vanilla) - he has previously tried modulen (tasted awful, so he had to tube feed) boost (unhealthy, too sweet, tastes awful) and ensure (couldn't do it). Finding absorb plus has been a real life savior. He has NO problem drinking five shakes a day. No nausea, no after taste. NO PROBLEM! This is an amazing product! VERY MUCH WORTH THE FINANCIAL INVESTMENT- IT IS IN FACT EXPENSIVE, BUT YOU GET WHAT YOU PAY FOR WITH ABSORB PLUS. THANK YOU.
