Your 3pm slump is a blood flow problem
Nitric oxide levels drop about 50% by age 40. Less nitric oxide means less blood flow, which shows up as afternoon fatigue and brain fog that another coffee only covers.

WHY 3PM FEELS LIKE THIS
Afternoon energy depends on how well blood moves
Blood carries oxygen and nutrients to your brain and muscles. Nitric oxide keeps blood vessels relaxed so that delivery keeps up through the day.
1
Nitric oxide drops with age
Your body makes about half as much by age 40.
2
Blood flow slows
Narrower vessels deliver less oxygen to your brain and muscles.
3
Energy runs low
That shows up as the 3pm dip, slower recovery and brain fog.

- CDChrista D.Verified BuyerReviewingNitric Oxide SupportI recommend this productHow old are you? 35-44What is your gender? FemaleCategory EnergyRated 5 out of 5 stars13 hours agoReally Works
Since hitting middle age I have been lethargic and working on changing everything from sleeping habits, to diet and exercise, to vitamins and other supplements, etc... This is the first thing that has made a significant difference in how I feel. It's not like drinking coffee (which I can't drink anymore because of acid indigestion), but there's just more life force in my all day, and my brain is sharper and am am much happier.

- PSPetra S.Verified BuyerReviewingNO Starter KitI recommend this productHow old are you? 45-54What is your gender? FemaleCategory Energy, CirculationRated 5 out of 5 stars2 weeks agoNO Support works
I am enjoying this supplement. It’s easy to incorporate with other supplements I already use. I take one pill first thing in the morning and the second one with my lunch. I have noticed having more energy and improved blood circulation. My feet are not as swollen as they used to be by the end of the day. The test strips are simple to use and the results are easy to read. I have gone from “Very Low” level to “Target”.
