At age 63, with a creatinine level of 3.0, it's important not to take Antoxipan DS or any supplement regularly without consulting your doctor. Some ingredients in these supplements, such as certain antioxidants, minerals, or vitamins, can accumulate in the body or interfere with kidney function. Even though Antoxipan DS is usually safe for healthy people, it may not be suitable for someone with reduced kidney function. Always talk to your nephrologist or treating physician before starting any supplement. They can guide you on what's safe based on your kidney health, age, and any medications you're taking.
