The suggested use on the package shows as a dietary supplement…But this is not, read above and count how many vitamins it has. TOO MUCH OF ANY VITAMIN CAN CAUSE TOXICITY. The common signs of this condition include: A sudden fever, low blood pressure, HEADACHE, muscle aches, confusion, diarrhea, nausea, vomiting.

There are reports it causes headaches, as well as other side effects, if you read through the customer feedback posted online. Plus, there’s no detail about the supposed clinical study that supports claims.


Before going for company-produced boosters try what our mother nature gives to you, veggies, fruits, berries, nuts; or even better – do not use boosters at all, enjoy natural food instead. Read What does the food you eat have to do with how your brain functions?

    I never get headaches, now that I started taking Focus Factor, i have started getting headaches primarily on the left side of my head. Is anyone else experiencing this?

      Yes i just started taking Focus factor and I am getting really bad headaches so I decided to look up any reviews on focus factor. It also make me depressed and tired as a side effect.

    I tried it once and I got really sleepy and my pulse was slow. I thought maybe I needed something to eat to wake myself up but that only helped once. I only took one pill. Not going to try it again no matter the supposed benefits.

    it made me feel extreme dizziness and seemd to have lost my eyesight as well. I stopped it immediatetely.

    Took 2 weeks to recover back to normal

    I’ve been taking it for the past two weeks.
    I feel a pain in my chest and feel that my heart is pounding unnecessarily hard.
    I took four per day last week and I cut it down to two per day this week. But I still have the same problems.
    I’m thinking of giving it up altogether.

    It has also made me dizzy and anxious. The only time I ever get anxiety is when I have to fly. Now it is daily for no reason. As of today no more focus factor.

    I Just took my first pill and I am rethinking this pill. I have issues with anxiety already and this made my hands sweat my vision blurry and not feel well at all. I don’t think ill be taking a 2nd pill. I only found one positive comment about the drug. I wish I would have reviewed this before taking the pill. lets hope I make it through the day

    I tried Focus Factor, it made me confused, I forgot words and names, I thought why is this happening to me if my memory is supposed to be better. I’ll finish the bottle and see what happens.
