Biophotonic glass is a special type of violet glass that helps protect the contents from harmful light exposure, preserving freshness and potency for longer.

It filters out the 'good' and 'bad' frequencies of the light, in particular UV & infrared. That means that all the light that harms content is blocked off, and the UV light that actually protects the content (think of UV disinfection) is allowed to enter the glass. This increases the shelf life and helps to maintain the purity of the electrolytes.
