Is 67 mg of Caffeine Safe?

Yes — for most adults.

The FDA recommends up to 400 mg/day for healthy adults. That means:

• 67 mg = only ~17% of the daily limit.

• You’d need about 6 drinks of 67 mg each to reach the 400 mg max.

Special Cases:

• Pregnant women: Limit to 200 mg/day → 67 mg is safe, but 3 servings would hit the max.

• Teenagers: Max 100 mg/day → 67 mg is two-thirds of their safe daily limit.

• Children: Should avoid caffeine completely.
