“I noticed a marked sharpness in my ability to focus and a very time-released energy…”
“I have worked with tonic herbs for two-thirds of my life, and I would have to say that HCF A20® is a good supplement. My experience with herbs and food medicine makes me a subjective customer.
I am not inclined to 'lean' in the direction of what might be considered 'shortcuts,' such as vitamins. That being said, my experience with A20® has been really great.
After taking A20®, I noticed a marked sharpness in my ability to focus and a very time-released energy that is not too much, not too little, as is sometimes the experience with tonic herbs.”
