A half teaspoon of Moringa powder from a farm in California which specializes in Moringa products--that worked fine. It smelled good, fresh, and tasted good, but it seemed to me that it would not be doing much unless I could eat more. So I wanted to up it to a whole teaspoon. This maybe would have been fine if I consumed any type of smoothie, but I don't anymore. Just trying to down it plain--a whole teaspoon--I didn't like. It didn't give me bad symptoms, I just didn't like that much dry!
I gave it up--probably prematurely. I think if you consistently drank smoothies or ate big vegetable stir frys or made vegetable stews that you could sprinkle some over, Moringa powder would prove to be a useful addition, especially for a vegan or vegetarian.
But I found a great use for the 1 oz bottle of Moringa oil I also purchased. I add a big drop to the leave-on hair conditioner I use, and it makes my curly hair look smooth, unfrizzy, neatly wavy--not oily. I got the idea when I saw hair products in a good salon with Moringa Oleifera. The oil seems to have different properties. It is not like the other nut or vegetable oils I know. It feels different and very nice on the skin too.
Worth continuing to experiment with it!
