To debunk the reviews that say the jar is half full, I emptied the brand new entire jar of powered onto a kitchen scale, it was exactly 3.7 oz which is what is printed on the label. It might look half full but it's no different than a bag of chips, full of air made to look full then you open it and there's like 6 chips lol! It's just the jar size they chose, I like the jar because it's glass and I'll reuse it for some DIY projects when it's empty. Btw the drink is fantastic! Hubby liked it too. I used a milk frother to mix unsweetened vanilla almond milk, with 9 drops of stevia (from Trader Joe's)... Yummm! Try it, so good for you
