My go to Vitamin C
I love this vitamin C! It absorbs easily into my system and doesn't hurt my stomach. It doesn't have extra fillings or coatings so I feel I am getting pure nutrition. Mixed with my morning smoothy it gives me the daily boost I need!
Dependable Quality
I have been buying Buffered Vitamin C Powder for many years. It is easy on my stomach and a quality product. I highly recommend it.
A necessity for me
Have taken for years as mixes well with other powders and easy on the stomach, and being a powder, I can adjust the dosage as needed.
This dissolved very well and tasted great!!
