What if you could delay caffeine delivery and make it last longer? This month we review the newest addition to the “energy-drink-in-disguise” brand that continues to defy energy drink stereotypes. We discuss key ingredients, how it compares to other caffeinated beverages of the same strength, and when to consume it per Level of Fatigue.
The Energy Drink of the Month for March 2017 is AvitaeXR.

Key Ingredients and Benefits
The ‘Xtended Release’ beads of caffeine – ZUMXR Proprietary Energy Blend
This energy blend is what makes up those tiny little beads you see floating around in the clear can of AvitaeXR. These beads contain caffeine but since the caffeine is tucked inside the little ball, it delays the delivery of caffeine to your system.
Attention Science Nerds and Chemistry Buffs: How this delayed delivery works is worth a separate post (coming soon). If you’re a science nerd like me, we can geek out together over the magic of delaying (not preventing) digestion in the complex gradient of digestive juices and pH levels in the GI tract.
Natural Caffeine
For the rest of the Avitae line, the source of caffeine is green coffee beans. It’s safe to assume the ‘natural caffeine’ in this product comes from the same source.

Other ingredients
- Carbonated Water – makes the beverage crisp and refreshing; Notably, carbonation slightly irritates the stomach, which slightly improves delivery of caffeine through the stomach lining
- Cane Sugar
- Citric Acid – helps combat the bitterness of caffeine
- Natural Flavors
- Sodium Citrate – the sodium salt of citric acid; Used for flavor and as a preservative; has a sour-salty taste
- Pectin – gives a little more mouthfeel (liquid thickness/heaviness)

Caffeine Comparisons
It’s unusual to find an energy-drink-in-disguise so clean, ingredient-wise, and yet so powerful, caffeine-wise. Avitae has 250 mg caffeine per can, which is about the same as a can of Rockstar Energy (240 mg)!!! However, it’s crucial to note that with AvitaeXR you are only getting 125 mg of caffeine at a time: 125 mg free floating caffeine immediately in the liquid; 125 mg later once your body finally breaks open those little beads. This makes AvitaeXR almost more powerful than Rockstar because of its ability to last.
When to Consume = Fatigue Level 4
***Because this energy drink has an extended release of caffeine, you’ll want to avoid drinking this one if you plan on sleeping in the next 6 hours.***
During the GreenEyedGuide Caffeine Challenge (Day 6), we talked about how Fatigue Level 4 is for Energy Emergencies! This is Level 4 out of 5, and Level 5 is the point where no caffeine can save you. [watch the whole YouTube video]
For Fatigue Level 4, the caffeinated beverage you choose should have the following characteristics:
- Carbonated or concentrated (energy shots)
- Over 200 mg caffeine per serving (400 mg is the daily max for adults)
- Does not have to be sugar-free
To learn more about how carbonation and juice play a role in a drink’s potency, visit the 5 Levels of Fatigue page. The 5 Levels of Fatigue system helps people reap the benefits of caffeine while avoiding addiction, dependence, tolerance, and toxicity,
Bottom Line
If you are entering an Energy Emergency and want something STRONG without having to settle for something super sugary and artificial, AvitaeXR is the solution.
