Analysis

This 133-count bottle provides a concentrated dose of 1000 mg of ascorbic acid per tablet. It is intended for those who want to support their immune function and antioxidant levels with a clean, one-a-day tablet. The form is standard ascorbic acid, which is the most widely used and researched version of vitamin C.

Because there are no added minerals or herbs, this product is very easy to add to a pre-existing supplement stack. It supports skin integrity and overall resilience to daily stressors. It’s a great option for anyone who prefers a straightforward vitamin without the bulk of a year-long supply.
