Tag: Ascorbic acid stability

According to dermatologists, a bottle of vitamin C serum typically lasts between 3 to 6 months after opening before it begins to oxidize and lose its potency. This guide explores how long does vitamin C last after opening, the factors that influence its degradation, and the best practices to maintain its effectiveness.

Ascorbic acid, also known as vitamin C, is a powerful antioxidant, but it is notoriously unstable and susceptible to degradation. While a tightly sealed container of pure ascorbic acid powder might last for years with minimal potency loss, the same cannot be said for many liquid formulations. Understanding the factors that impact its stability is crucial for ensuring you get the maximum benefit from your vitamin C products.

Most vitamin C supplements have a shelf life of about two years, though their potency can degrade significantly over time, especially when not stored correctly. As a notoriously unstable vitamin, factors like light, air, and heat play a huge role in determining how long can you store vitamin C effectively before it loses its benefits.

Did you know that up to 95% of vitamin C can be lost during certain food processing and storage conditions due to temperature and oxygen?. Understanding **what are the factors affecting the stability of ascorbic acid** is crucial for preserving its nutritional value in both foods and supplements.
