Oath Nutrition Sparkling Energy Drink, 10g Protein

When plain water feels dull but a full protein shake seems like more than you want, Oath Nutrition combines a sparkling drink with caffeine and complete protein in a can. Each 12-ounce serving has 100mg of caffeine sourced from green tea extract and 10g of protein containing all essential amino acids, with zero sugar and a Summer Citrus flavor. That makes it a convenient middle ground for a workday break or before a workout, though the 10g protein amount may not suit someone looking for a larger protein serving.

Technical details

This is a carbonated energy drink with protein, sold as a 12-pack. The listed flavor is Summer Citrus, and each can contains 100mg of caffeine and 10g of complete protein. The product description says the caffeine comes from green tea extract and that the protein includes all essential amino acids. It is also described as sugar-free. Those details make it different from a standard energy drink, which may focus on caffeine alone, and from a protein shake designed primarily around protein intake.

The combination is useful if you want both ingredients in one drink rather than carrying separate products. Still, 10g is the amount provided per can, so compare that with your own protein target rather than assuming it replaces a higher-protein shake or meal. The available details do not list other nutrition facts or the full ingredient blend.

Getting the most from it

There are no mixing steps in the product information: the protein, caffeine, and carbonation come together in a ready-to-drink can. Chill one for a desk break, or bring it along for a pre-workout drink when you want citrus flavor and a measured caffeine serving in the same format. It is also described as suitable for relaxing poolside, so its intended use is broader than workout-only hydration.

It makes sense if you prefer a fizzy, zero-sugar option and want some protein alongside caffeine. If you usually choose between a dedicated energy drink and a protein-focused shake, this combines elements of both, but it does not provide more than 10g of protein per can. The caffeine amount is clearly stated, if you track your daily caffeine, include it in that total.

Usage tips

Use the can as a convenient single-serving drink rather than treating it as a protein powder that needs preparation. For example, keep one cold for an afternoon work break when you would otherwise reach for a separate caffeinated drink, or have it before heading to a workout if the combination fits your routine. The Summer Citrus flavor and sparkling format are central to the product, so it will appeal more to someone who likes a crisp, carbonated drink than to someone who wants a still shake.

Not the best choice if your priority is getting a substantially larger protein serving from one drink, or if you want an uncaffeinated option. The description does not provide enough detail to assess other dietary needs beyond its zero-sugar claim, so people who rely on a full nutrition or ingredient profile should use that information when deciding.

Practical doubts

How much caffeine is in each can? Each 12-ounce can contains 100mg of caffeine, sourced from green tea extract.

Is the protein complete? The product description says its 10g of protein includes all essential amino acids.

Does it contain sugar? It is described as a zero-sugar sparkling beverage.

Buying verdict

Choose Oath Nutrition if you want a ready-to-drink, citrus-flavored sparkling beverage that puts caffeine and complete protein together without sugar. Its practical appeal is the combination and convenience, not a high protein count: the 10g per can is the key limitation for anyone comparing it with a drink chosen mainly to meet a larger protein goal. If that amount works for your routine and you enjoy carbonation, the format may be a better fit than buying separate energy and protein drinks, otherwise, a more protein-focused option is likely a closer match.
