Some customers report feeling more energy after taking veva for several weeks. Others report increased attention throughout the day, better control of blood sugar, and better sleep. You may also be unable to detect any changes, even while the veva molecules are working to keep you healthy and helping you life longer. If you wish to track objective measures of aging while using veva, we recommend first baselining your “inner age” with blood markers provided by services like insidetracker.com, and then retesting the same markers quarterly.
