I feel the effects of this supplement almost immediately and it clears up the foggy feel in my head quite well.
I bought this hoping it would reduce my dependance on blood pressure meds but it has some effect but not enough. Fresh celery works better but the number of stalks one has to eat to obtain effect is prohibitive.
This is one of the best brands I have used. The effect is immediate and the pills are easy to swallow.
I take a lot of Vitamin C and this brand is tasty and chewable which enables me to take it easier.
