The ideal dose of Moringa should be 2 teaspoons a day. To obtain that amount, you will need to take a least 7 capsules of Moringa a day. You else have to take into account that a lot of capsules are mixed with other ingredients and starches. If you prefer the capsules and will take a least 7 a day, please make sure that the ingredients are 100 per cent powder. The last thing to keep in mind is that the capsules are usually more expensive from $15 and up whereas half a pound of powder will only be $18 with shipping but will last a lot longer.
