Blackberry & Raspberry Smoothie with Chia Seeds

2 Servings

This smoothie recipe calls for blackberries and raspberries, both of which are famous for their potential anti-aging, anti-cancer, and cardioprotective properties. Cooled blackberry leaf tea, which has shown strong antioxidant and anti-cancer properties in test tubes, is used as the liquid base (if you have trouble finding blackberry leaf tea, you can also use another mild-tasting herbal infusion, or plain water, as the liquid base for this smoothie). Chia seeds – which are loaded with omega-3 fatty acids, fiber and protein – are added to the mix to further boost its nutritional profile.

You can make this blackberrry and raspberry smoothie with either fresh or frozen berries. If you're using frozen berries, omit the crushed ice the recipe calls for and let the frozen berries thaw for 15-25 minutes before using them.
