Based on research studies, some effects were seen as early as 30 days with lasting effects seen after 90 days. We suggest following the study duration to determine efficacy. Nonetheless, the amount of time to see benefits can also be influenced by one's unique biochemistry, use of medications, and the extent of support needed. Biochemical individuality is the concept that each person's nutritional and chemical makeup is unique and that dietary and other needs, therefore, vary from person to person.

I've been taking them about two weeks, didnt notice anything much exept maybe I'm not so sleepy. Could be because I sometimes forget.

I did not take it properly and unfortunately sometimes I cut down on the dosage to make it last a bit longer. But still I feel better, it is like I have more energy and I need less coffee to get me through the day- also truly I feel that I sleep better.
