I bought this drink for my husband because he constantly works out and skips breakfast. When we fond out he would be going for radiation treatments, i knew he would need better nutrition. I decided to look for a supplement that he would feel comfortable†able drinking. Our daughter who is a dietician recommended Koia since one of her patients gave her a sample to try. She told me it was an excellent supplement and that she felt her dad would like it. My husband has been drinking it for a least a week now and really likes it. He even feels better since using Koia. I would definitely recommend this supplement to anyone who needs one.
