I have heard about Protandim, a supplement in pill form. The cost is NZ$40 per week. It is sold through a multi-level marketing structure. I have heard that people are being paid for sales with skin care products that are part of the Life Vantage range; they have to sell the skin care products to make money. Apparently Protandim will be making presentations around New Zealand very soon. It was claimed that the product reduces oxidative stress and ensures mitochondria are healthy. It was claimed that the product is totally safe. This review of Protandim looks useful: https://sciencebasedmedicine.org/i-was-wrong-about-protandim/ The multi-level marketing approach is a particularly clever one; higher level marketers can make all sorts of suggestions about efficacy verbally that are amplified as they are passed down the chain. But, there's no record of the claims that are made. Here's the New Zealand site https://nz.lifevantage.com/products/protandim-dual/ Edited to remove details that might identify people.
