As a software engineer in my mid-40s, I have often struggled with brain fog, which obstructs my thought process. However, I have been taking this product for over 2 years now, and I cannot thank it enough for how it has helped me. It has enhanced my cognitive abilities to a point where my brain feels like it's in my 20s. I am now able to focus and complete my work effectively, even though I suspect I have ADHD. Occasionally, if I need to work for long hours without a break, I take two capsules, and it works wonders.
