While there are a number of Vitamin C products on the market I like this one. They use a USP standard for weight of each tablet.
Vitamin Basics & Tips
Understanding USP-Standard Supplements
The USP (United States Pharmacopeia) mark ensures supplements meet strict quality standards for ingredient accuracy, purity, and dissolution. This certification means each tablet contains exactly the labeled vitamin C amount without harmful contaminants.
Why Tablet Weight Matters
Consistent tablet weight guarantees uniform dosing. Unlike irregularly sized supplements, USP-standard tablets dissolve predictably, ensuring full nutrient absorption for optimal immune support and collagen production.
Vitamin C's Daily Benefits
This antioxidant fights free radicals, supports skin health, and enhances iron absorption. Adults need 65-90mg daily, but stress or illness may increase requirements – making reliable dosing crucial.
Common Vitamin C Questions
Q: Can I take it on an empty stomach?
A: Buffered formulas are gentler. Q: How long does it last?
A: Store in cool/dry places; most tablets remain potent for 2 years unopened.
Choosing Quality Supplements
Look for third-party certifications (USP/NSF), avoid unnecessary additives, and check expiration dates. Time-release tablets may improve tolerance for sensitive users.
