While probiotic strains can naturally occur in milk, the probiotics used in Provitalize are actually cultivated in an FDA-approved laboratory in the United States. This ensures that the strains are carefully selected and controlled for their quality and effectiveness.
One important aspect to consider is that probiotics do not possess nervous systems, which means they do not have the ability to feel pain. Therefore, the probiotics used in Provitalize are widely accepted as being suitable for vegans, as no animals are harmed or involved in the production process.
