Study: Interventional Study of High Dose Folic Acid in Gastric Carcinogenesis in Beagles
S.D. Xiao, X. J. Meng, Y. Shi, Y. B. Hu, S. S. Zhu and C. W. Wang. (2002) BMJ Journals. 50(1): 61-64

Participants: 8 beagles with gastric cancer

Duration: 15 months

Purpose: To determine whether or not folic acid has an impact on gastric carcinogenesis in dogs.

Findings: Folic acid administered to beagles results in a higher concentration of folic acid in their serum and gastric mucosal tissues. In the control group, where no beagles were given folic acid, all eight beagles had gastric cancer. On the other note, the beagles in the folic acid treated group, only three out of eight beagles had gastric cancer. Thus, scientific studies show that administration of folic acid reduces the risks of dogs getting gastric cancer.

Riboflavin (Vitamin B2)

Serves as an essential flavoprotein-enzyme that helps regulate cell metabolism.

Riboflavin deficiency can cause weakness in muscles, loss of appetite causing collapse and erythema.

Study: The Riboflavin Requirement of Adult Dogs at Maintenance is Greater than Previous Estimates J. L. Cline, R. A. Easter and J. Odle. (1996). Journal of Nutrition. 126(4): 984-8

Participants: 20 dogs

Purpose: To determine the trend of EGRAC with the increase of riboflavin concentration.

Findings: : With increasing concentration and intake of riboflavin, a overall trend of the EGRAC* decreases. This activity coefficient is used to determine the efficiency of riboflavin to support the enzyme function. The higher the coefficient results in a larger amount of unsaturated glutathione reductase which results in a lack of FAD. Thus, the lower concentration of EGRAC will reflect a higher amount of FAD.

*EGRAC: Erythrocyte glutathione reductase activity coefficient

Yucca Schidigera

Naturally reduces joint inflammation & high in antioxidants to boost immune function and overall health.

Main Functions

  • • Serves mainly as an inhibitor to reduce inflammation in tissues and prevents inflammation.

Purpose: To determine whether or not Yucca Schidigera inhibits nitric oxide synthase.

Findings: Nitric oxide is the main cause for pain and inflammation in tissues. Yucca Schidigera (yuccaols derivative) has the ability to inhibit iNOS* in tissues. Scientists have proven that with increasing concentrations of Yucca Schidigera will also cause an increase in nitric oxide inhibition respectively. This as a result will reduce inflammation in tissues.

iNOS: Nitric oxide synthase
