RE: Summary of Results for Acute Oral Toxicity Testing on CELLFOOD®

Dear Mr. Negrete:

We have completed the above referenced testing. Under the conditions of this study, the single dose acute oral LD₅₀ of CELLFOOD® appears to be greater than 5,000 mg/kg of bodyweight in male and female rats.

Please let me know if you have any questions or need additional information.

Sincerely,
PRODUCT SAFETY LABS
