throw away your greens powders and make greens cubes for your smoothies instead

kale + spinach + swiss chard
add a touch of water if the mix gets too thick (or add cucumbers)

> cheaper
> more nutrients (fresh >>>)
> no additives or sweeteners (better taste)
> can make your own mix
> FIBRE

i spent ~$7 and made 34 cubes (17 servings, about ~30g of greens total)

you can really enhance the nutrient profile and benefits by adding any of the following: moringa powder, spirulina, fresh turmeric, fresh ginger, ground flax seeds, chia seeds, ashwagandha powder
