ZOA Energy Drink Review
ZOA is Dwayne Johnson's zero-sugar energy drink. A 12 ounce can has less caffeine than Celsius or Alani Nu. Here is what the label actually says.
Quick Summary
A zero-sugar energy drink with 160 mg of caffeine in the 12 ounce can. Fine for a healthy adult who already handles that dose. Not a health drink.
ZOA caffeine by size
| Feature | Caffeine | Vitamin C |
|---|---|---|
| 12 fl oz | 160 mg | 90 mg (100% DV) |
| 16 fl oz | 210 mg | 120 mg (130% DV) |
FDA says up to 400 mg of caffeine a day is not generally linked to dangerous effects in healthy adults. Two 16 oz cans are 420 mg before any coffee. For pregnancy, ACOG advises staying under 200 mg a day from all sources. One 16 oz can is already over that.
ZOA vs Celsius, Alani Nu, and Bloom
| Feature | Caffeine | Sweeteners |
|---|---|---|
| ZOA | 160 mg | Sucralose and acesulfame potassium |
| Bloom Sparkling Energy | 180 mg | Sucralose. See the Bloom review. |
| Celsius | 200 mg | See the Celsius review. |
| Alani Nu | 200 mg | Sucralose and acesulfame potassium. See the Alani Nu review. |
ZOA has the least caffeine per 12 ounces of these four. For lower-caffeine options, see [healthiest energy drinks](/energy/energy-drinks/healthiest-energy-drinks).
Is ZOA energy drink healthy?
Compared with a sugary energy drink, ZOA has zero sugar. That is the main difference. Three other points decide whether it fits.
Caffeine. 160 to 210 mg a can is a real dose. It can fit most healthy adults inside FDA's 400 mg a day. It is not for children, teens, or people who are sensitive to caffeine.
Sweeteners. ZOA uses sucralose and acesulfame potassium. Both are FDA-permitted. If you avoid them, this is not your drink.
Vitamins and electrolytes. Vitamin C and B vitamins are listed. Most people who eat a varied diet do not need them from an energy drink. The brand names magnesium, potassium, and sodium and does not print the milligrams on the FAQ or the Why ZOA page, so those amounts are not filled in here.
ZOA's own FAQ says the drink is not recommended for children, people sensitive to caffeine, or pregnant or nursing people. Dwayne Johnson is the face of the brand. That is marketing, not a medical endorsement.
Who should skip it
- Children and teens.
- Pregnant or breastfeeding people. ACOG's figure is under 200 mg of caffeine a day.
- People with heart rhythm problems, high blood pressure, or anxiety that caffeine makes worse. Ask a doctor.
- Anyone already near 400 mg a day from coffee or other drinks.
