Thank you for reaching out. For maximum results, it's ideal for taking only one capsule daily, preferably with a meal containing healthy fats. It's not necessary to take more but to be consistent with your usage. Noticeable effects may be seen within 1-2 weeks; however, most C60 users report increased energy and mental clarity after 3-4 weeks of daily use and improved overall health and decreased inflammatory response within a few months of everyday use. Unfortunately, this product is not recommended for pets; we apologize.
