 We added the coffee berry extract, that phenomenal antioxidant that's more potent than blueberries and strawberries for powerful antioxidant protection. I added the vitamin D because it's so important across the board, great for bone health, but also for seniors, vitamin D, so important for muscles, especially as we get older, for strength and coordination. So this is a very comprehensive formula. Again, this would easily cost you 80, 90, 100 bucks to replicate on your own, but today it's free.
