★★★★★
“As a pharmacist I love that this supplement is third party tested. I always recommend third party tested supplements to my patients. I have been taking Keep Focus after my long commutes as I start work and have noticed a calmer focus and energy compared to when I was stopping for an extra cup of coffee. Will buy again!”
★★★★★
“I'm a night shift nurse and Keep Focus has helped me stay locked in throughout my shift without the jitters that energy drinks give. Highly recommend this product!”
★★★★★
“I placed my order on Thursday and had my Keep Focus delivered on Saturday, talk about speedy! I have been using it for several days now and I'm loving the smooth focused energy! I'm trying different times of the day to figure out when is the best time for me to take it, so far around 11 AM is my favorite. It's really helping me stay focused and continue to be productive throughout my entire day at work. Love the mental clarity it provides. I bought an extra bottle to bring to the office so others on my team can try it! Great product, highly recommend everyone tries it!”
★★★★★
“The delivery was very quick. I've been using this for a couple of weeks now and I can tell it's made a difference in staying alert and focused. I work in the healthcare industry so I definitely need to stay focus at all times.”
★★★★★
“I really enjoy the clean none jittery feeling that it gives me unlike 4 cups of coffee. I am a big coffee drinker. When I take keep Focus I only drink one or two cups and have energy and focus all day, without the caffeine crash.”
★★★★★
“I started taking one capsule right before a round of golf. I didn’t notice any significant effect but at the end of a round I notice my energy level was still high. The thing I noticed most was being more calm when I had one of the must make putts during a round. Highly recommend”
★★★★★
“As a big coffee drinker I was skeptical about how well this would work for my tolerance, but I’ve been really surprised with how much I like this! For sleep hygiene reasons I am (begrudgingly) eliminating my afternoon coffee, but I still feel my battery die. I reach for this around 3-4 pm and have just enough energy to make dinner, do bath/bed time, etc without dragging (and even do something for myself). Then I still fall asleep easily. It doesn’t replace my morning caffeine but definitely has its purpose later in the day! I will be keeping it on hand as my husband has been trying it and liking it himself.”
★★★★★
“I started incorporating Keep Focus into my daily routine several weeks ago. It helps keep me focused without the jittery and anxious feeling of coffee. It’s a great product that I intend to keep using!”
Pharmacist founded
Made by a pharmacist who wanted a more intentional formula.
I’m Dominic, a pharmacist and the founder of DoseGeni.
When I formulated Keep Focus, I didn’t want to build another product around simply pushing caffeine higher.
I wanted a more intentional approach: a measured caffeine dose paired with twice as much L-theanine, with every ingredient and amount clearly listed.
That became Keep Focus.

Before You Get Started
Frequently asked questions.
Will this make me jittery or anxious?
Keep Focus is formulated to provide smooth, balanced energy. L-Theanine helps offset the overstimulation that caffeine alone can cause. Individual responses vary, especially if you're sensitive to caffeine.
How does this work?
Keep Focus combines caffeine with L-theanine and magnesium to promote alertness while supporting calm focus. The ingredients are selected to work together, helping you feel focused and energized, not overstimulated.
How much caffeine is in it?
Each capsule contains 100 mg of caffeine, which is about the same as a small cup of coffee. The caffeine is balanced with L-theanine and magnesium to support smoother, steadier energy without a spike or crash.
How long does it take to feel the effects?
Most people notice effects within 30 to 60 minutes, though results vary based on metabolism, caffeine tolerance, and whether the capsule is taken with food.
Can I take this every day?
Yes, when used as directed. Many people use Keep Focus as part of their daily routine, especially on work or high-focus days.
Who should not take this?
Do not use if you are pregnant, nursing, sensitive to caffeine, or taking medications that interact with stimulants. If you have a medical condition or take prescription medications, consult your healthcare provider before use.
How should I take this?
Take 1 capsule daily, preferably in the morning or early afternoon. Avoid taking late in the day to prevent sleep disruption. Do not exceed the recommended dose.
What if it doesn't work for me?
We offer a 30 day money back guarantee. If Keep Focus isn't right for you, reach out and we'll make it right, no questions asked.
