    This product comes in 3 different strengths,10mg,20mg,40mg.Unfortunately, Extra Strength is perceived as the strongest. It is only 20mg. I thought I was buying the 40mg bottles. The product itself is amazing! I take 4 a day or more of the 40mg.

    Thanks for your feedback!

    Great! Great!

    I am 52 years old. At the beginning, I tried the one which only 10mg Apoaequorin and I felt a bit better. Then I tried this 20mg Apoaequorin. I found the result is very obvious. I have just introduced it to some friends. I buy this every month, but it is always out of stock :(

    Thanks for your feedback!
