Very good
Quick Review of Zinc C (Zinc + Vitamin C) I take Zinc C to boost my immunity, especially during weather changes or stressful periods. After a few weeks, I noticed I caught fewer colds and recovered faster when sick. The pills are easy to take and not hard to swallow. This is an essential supplement combo that I plan to continue using long-term.

Great taste
I was surprised by the size of the jar. The mix is easy to prepare, the taste is great, and the texture is very smooth. However, the last two jars I bought were gritty and did not mix well. I will not be buying this product again.
