There are many supplements I recommend for living a longer life. Much of this can be discussed in your dietary lifestyle. Eating less refined sugar is the key
I do recommend any of the naturally occurring plant pigments called carotenoids. These function as potent antioxidants. A lot of these can be found in foods such as vegetables and fruits. The percentage of carotenoid plays a major role in the length of a healthy life span
I usually recommend astaxanthin which is much stronger than beta carotene. Another is lycopene which is present in tomatoes ( the highest concentration found in tomato paste, and grilled tomatoes)
