## Customer Reviews

### ⭐⭐⭐⭐⭐ These do help!
*by  on Reviewed in the United States September 20, 2026*

I will say im a bigger fan of the lemon than I am the blueberry but its still not bad. Ive only tried the sparkling of both flavors and they aren't bad, just prefer the lemon more lol.They definitely help when fasting to give that extra boost your needing to help through the day. Of course if your a very active person, these will help you not feel like death during a fast.

### ⭐⭐⭐⭐⭐ Great partner in fasting!
*by  on Reviewed in the United States September 25, 2026*

Good taste and helped me through my fast. Was my first time and helped me feel hydrated.

### ⭐ Smells of perfume
*by  on Reviewed in the United States July 10, 2026*

Normally, I love this product, but when I received it, it smells heavily of perfume for some reason. Even washing the cans it still smells like perfume.
