Thank you for reaching out! Optimal Liposomal Vitamin C has been tested and remains stable for at least 24 months from the "Made On" date listed at the bottom of the bottle. The product may appear brown due to the phosphatidylcholine derived from sunflower seeds. It is made with natural ingredients, including natural flavors. If the taste is too strong, mixing it with a bit of juice or water can help. The flavor may vary slightly between bottles since we use natural (not artificial) flavors
