Back to Vitamin C (Ascorbic Acid)

Daily-use question

Can I take Vitamin C (Ascorbic Acid) every day?

Yes, daily use is appropriate and often necessary for effect. Vitamin C (Ascorbic Acid) is a foundation-level supplement. Its mechanism rewards consistent daily exposure rather than acute dosing. Tolerance is not a meaningful concern at standard doses; the main risk is over-dosing in pursuit of bigger effect, which is rarely linear.
