 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 is 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 to replicate on your own, but today it's free.
