The 'shakes' are better than caps because they start cleansing from the mouth down...plus people often don't drink nearly enough water when they use the capsules. If you want to use capsules...make sure that you supplement them with at least 1 shake a day using the powder so that you clear out the very upper part of the GI tract...and drink, drink, drink your water!!!

EMMY,
For me i would rather use the powder form, i get the stores brand because its cheaper and it works the same. I have a problem swallowing big pills and capsuls.
If you use the powder mix it with cold water and use enough water in the glass and drink it down fast so it dont gell.
I think the powder works much better in the system also.
