Measure
ACCS100 High Dose
Participants will receive a total daily dose of 3 grams of ACCS100; 1 gram three times a day with meals. ACCS100: ACCS100 is not absorbed. The dose is estimated based on the volume of the gastrointestinal tract. We estimate that the average human intestinal tract has a volume of approximately 4 liters. In the high dose group, the effective concentration in the gut is 0.75 milligrams per milliliter. In the low dose, the effective concentration in the gut is 0.375 milligrams per milliliter. The test article is made by filling gelatin capsules with 500 milligrams of ACCS100. There are no excipients used in the manufacturing process of the test article.
ACCS100 Low Dose
Participants will receive a total daily dose of 1.5 grams of ACCS100; 500 mgs three times a day with meals. ACCS100: ACCS100 is not absorbed. The dose is estimated based on the volume of the gastrointestinal tract. We estimate that the average human intestinal tract has a volume of approximately 4 liters. In the high dose group, the effective concentration in the gut is 0.75 milligrams per milliliter. In the low dose, the effective concentration in the gut is 0.375 milligrams per milliliter. The test article is made by filling gelatin capsules with 500 milligrams of ACCS100. There are no excipients used in the manufacturing process of the test article.
Placebo
Participants will receive placebo capsules shown not to absorb mycotoxins three times a day with meals. Placebo: Placebo is calcium carbonate, USP. This calcium mineral does not absorb mycotoxins, specifically aflatoxin and fumonisin. This mineral has approximately the same physical appearance as active test article.
