I would add that tartaric acid is also a no-no. It is a product of candida and other yeasts.

"The only source of tartaric acid is yeast. This compound forms a sludge in the wine brewing process and has to be removed. Wine is sugar-water fermented by yeast (Saccharomyces cerevisiae) to alcohol and other yeast products. Humans do not produce this chemical."

"Treatment with the antifungal drug Nystatin kills the yeast and values for tartaric acid steadily diminish with antifungal treatment. Fifty percent of patients with fibromyalgia often suffer from hypoglycemia even though their diet may have adequate or even excessive sugar.

One of the reasons for the hypoglycemia may be due to the inhibition of the Krebs cycle by tartaric acid."

The amounts in the product you mentioned is probably minimal though.
