Furthermore, it has been reported that chitosan can combine with acidic substances suspected to be uremic toxins, resulting in their greater excretion from the body, thus in improved clinical conditions [8, 16]; whether these same effects are exerted in dogs has not been studied but the present results may suggest that one or more of these mechanisms operate also in this species. In contrast, none of the dogs in group B had died by 48 weeks and was excluded from analysis. Wuolijoki E, Hirvela T, Ylitalo P. Decrease in serum LDL cholesterol with microcrystalline chitosan.

An 8-week, double-blind, placebo-controlled trial of 51 women found that use of chitosan at a dose of 1,200 mg twice daily slightly reduced LDL ("bad") cholesterol as compared to placebo, but did not affect total or HDL ("good") cholesterol levels.37 Another 8-week trial, this one enrolling 84 people, also found modest benefits.39, However, a 4-month, double-blind, placebo-controlled trial of 88 individuals found no improvement in cholesterol with 1,000 mg 3 times daily of a different chitosan product.31 A 7-month study of 84 men given placebo or 1,200 mg of chitosan daily also failed to find benefit.43 Furthermore, in a 10-month, double-blind, placebo-controlled study of 130 men and women, use of a special microcrystalline form of chitosan at a dose of 1,200 mg twice daily again failed to improve cholesterol profile.40. The fact that serum creatinine concentration was significantly more stable and for a longer period of time in dogs receiving the supplement (Group B) is consistent with the hypothesis that delay in development of uremic crises and associated mortality rate was related, at least in part, with a reduction in the progression of renal failure.
