Vitamin C (Ascorbic Acid) for Dogs In Powder Form

I am a fan of Vitamin C in dogs. (And people)

I take 2 grams once a day. That’s not a recommendation but it IS a statement of experience. I know how it feels, tastes and it’s influence on my health and habits. (There is a concern about bowel effects and I’ve experienced none)

Vitamin C is described in another article in the site. But this article you’re reading now, discusses the use of Vitamin C in powder form.

It also describes my calibration of some spoons you can use to measure it.

I bought some Vitamin C in powdered form ( The economy is absurd compared to capsular form.

I bought little tiny spoons, two kinds. Plastic and stainless.

I bought a gram scale which I found VERY effective and easy to use.

Then I measured how much of the Vitamin C powder filled each spoon.



1/64 tsp




1/32 tsp




1/16 tsp




1/8 tsp




1/4 tsp


The gram scale was like $14 and the spoons were $8.
Vitamin C powder is white and slightly granular. It dissolves rapidly in water. It has a really acrid taste like powdered Lemon skin.
