Is this biotin supplement suitable for vegan, keto, halal, or gluten-free diets?

Yes, the supplement is formulated with synthetically-derived biotin and common pharmaceutical-grade excipients, making it vegan, keto-friendly, halal-compliant and free of gluten, wheat, dairy or animal-derived ingredients.

What is the optimal way to store this biotin supplement once opened to maintain its potency?

Store the bottle in a cool, dry place away from direct sunlight, keep the cap tightly closed, avoid high humidity and temperatures above 30 C, and keep it out of reach of children to preserve stability and potency.
