Best remedy for winter months
This product works and is effective. It is a big reason why I have very little illness during the winter months. When I am starting to feel sick I take this. This is a large tub with powered vitamin C.

My Experience with Doctor's Best Vitamin C Powder
I recently tried Doctor's Best Pure Vitamin C Powder with Q-C and was impressed by its high quality and effectiveness. The powder form allows me to customize my dosage and easily mix it into drinks. It dissolves well, making it a convenient way to boost my Vitamin C intake. The taste is slightly tart, and I think a package is OK.

Excellent
Great presentation, it's like taking a lemonade without the sugar, one thing I liked the most it's that it's only one ingriedent.
