Yes, amla is great stuff. The vitamin C in amla is stable and was found to be 12 times stronger than synthetic ascorbic acid. In addition amla protects the DNA from heavy metal damage and raises superoxide dismutase (SOD) levels about 80%. I use amla in a lot of formulations for these reasons.
Make sure it is amla powder though and not standardized. The standardized amla is standardized for tannins, which are antioxidant, but they also bind various nutrients and other beneficial compounds.
