I have been shopping supplements, health food specially items, and exchanging advice in this store for years. The owner is a gentleman by the name of Alex. His father also ocassionaly works there. Both are extremely personable and polite with tons of knowledge. They also have a certified naturopath on staff, Argentina, who is frequently there with a wealth of advice.
I've never been steered wrong. Thanks to them I no longer take meds for acid reflux and their supplements are top notch brands.
If you're in the Atwater area, it's the MUST GO place for healthy advice and products.
