What is in Ultra Preventive X?

Each row as the label prints it, per serving of 4 tablets. The capsule beside an amount places it among every product in the NIH database that lists the same ingredient: the bar is the middle half of their amounts, the line in it the median, the whiskers the 10th and 90th percentiles; the green tick is the FDA Daily Value and the red dashed tick the adult upper limit (IOM).

Is that a lot?

The rows in the top or bottom tenth of the products that list the same ingredient, and any above the adult upper limit at the most servings a day the directions give:

  • Its 1,000 mg of vitamin C is higher than 91% of the 18,583 vitamin C products that print an amount; 445 list more.
  • Its 100 mg of thiamin is higher than 94% of the 9,830 thiamin products that print an amount; 163 list more.
  • At 1 serving a day, the most its directions give, the label lists 190 mg of niacin, 5.4 times the adult Tolerable Upper Intake Level.
  • Its 100 mg of vitamin B6 is higher than 96% of the 15,277 vitamin B6 products that print an amount; 173 list more.
