Great product, terrible taste!
First, I'll start by saying, the customer service here is top notch! Now, the NMN. So far, I really like the way I feel, definitely more energetic! I haven't used it long enough to see longer term effects, but so far so good. The absolute only thing I do not like, the taste!! It's so bitter, but I guess it's a small price to pay in order to look and feel more youthful!
