What It Is

Rx Vitamins Onco Support Powder is a veterinary-formulated nutritional supplement in powder form for dogs and cats. It contains a comprehensive blend of free-form amino acids (L-Glutamine, L-Arginine HCl), antioxidants (Sodium Ascorbate, Green Tea Extract standardized to 60% EGCG, Spirulina), multi-strain probiotics, prebiotic Larch Arabinogalactan and Fructooligosaccharide (FOS), and herbal extracts including Bio-Agaricus (Agaricus blazeii mycelia and fruiting body) and Milk Thistle (Silybum marianum) seed extract standardized to 80% silymarin, along with vitamins A, D, E, Zinc, and Selenium.

How It Works

The amino acids L-Glutamine and L-Arginine HCl support normal tissue integrity and cellular maintenance.

The multi-strain probiotic blend (Lactobacillus acidophilus, Bifidobacterium longum, B. bifidum, B. lactis, and Lactobacillus casei) combined with prebiotic Larch Arabinogalactan and FOS promotes healthy gut flora and normal digestive function. Milk Thistle (Silybum marianum) seed extract standardized to 80% silymarin supports normal liver function, while Bio-Agaricus (Agaricus blazeii mycelia and fruiting body) and key micronutrients—Zinc, Vitamins A, D, and Selenium—further support normal immune defenses.
