Greenpet Vitamin C Powder is available in two varieties:

  • Pure sodium ascorbate powder which is virtually tasteless, so it can easily be added to food.
  • Pure Ascorbic acid which is beneficial to help acidify the system.

Most animals synthesise vitamin C naturally in their bodies, but due to stress, racing, travel, illness or injuries the demand may easily exceed the supply.

Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin that is naturally present in some foods, added to others, and available as a dietary supplement. Humans, unlike most animals, are unable to synthesize vitamin C endogenously, so it is an essential dietary component.

    Have sourced Sodium Ascorbate for many years from many suppliers – This is the best quality yet –
    Back in mid 80’s an article in the British Medical Journal related to doctors in the UK successfully treating and reversing arterial plaque with large doses of sodium ascorbate – Wonder what prompted them to not tell the public….

    I’ve used high doses of vitamin c to cure ewes post lambing. Ewes will go down with stiff back legs, after 3 days I can’t catch them in the yard to administer the vitamin. I use vitamin c for young lambs to give them a boost, does wonders.

    I highly recommend this Vitamin C. We purchased this for a 12 week old pup who’s immune system needed support (mild localised demodex and was down on his pasterns/splayed feet). Having already started other immune-boosting supplements, I needed a Vit C that was odourless, tasteless and able to be sprinkled on his food. Also had to be the non-calcium salt of ascorbic acid (ie not calcium ascorbate), as this was during a peak growth time and giving another source of calcium to a growing puppy is risky. This was the only Vit C product on the market (human or pet) that was suitable!!! Customer service from Greenpet was very good and the screw top container great.

    This product is across the board amazing! With no flavour it can be used with almost any animal from guinea pigs through to horses. The almost immediate visible improvement it shows with any failing animal, when used as rescue product is outstanding & I would highly recommend any pet owner having a tub of this in their “must have” pet product cache.

    Currently using it in a high dosage for my dog with cancer. I slowly increased dosage as recommended and there are no side effects at all. Great product!

    Clearly palatable as my cats and dogs happily eat the food with this powder mixed in to it:)
