Mango Passion Fruit Energy Drink - 12 fl oz

Yerbaé's Mango Passion Fruit Energy Drink is a 16 fl oz sparkling beverage powered entirely by yerba mate — the South American botanical leaf long used for clean, sustained mental clarity. At 160mg caffeine per can with zero sugar, zero calories, and zero carbohydrates, this is the brand's highest-output SKU and one of the few yerba mate–based energy drinks at this caffeine level that skips both synthetic sweeteners and sugar entirely.

What separates Yerbaé from the conventional energy category isn't just what's absent — it's the source. Yerba mate caffeine is paired naturally with theobromine and polyphenols present in the leaf, a profile that many drinkers associate with smoother energy curves than coffee or synthetic caffeine isolates. The mango passion fruit flavor is naturally derived, giving it a tropical brightness without the cloying sweetness typical of mass-market energy drinks.

Yerbaé carries a full stack of third-party verifications: Non-GMO Project Verified, Certified Gluten-Free, Vegan, Keto-friendly, and Sugar-Free. That combination is uncommon at this caffeine level and positions it squarely for shoppers reading every label — not just the front panel. The 16 oz format (vs. the brand's 12 oz cans) delivers a full 160mg caffeine, 33% more than the 12 oz version's 120mg.

Customers who've tried Yerbaé consistently note cleaner energy without the jitteriness or hard crash they associate with conventional energy drinks — a pattern that tracks with the yerba mate mechanism. With a 4.1-star rating across 348 reviews on the 16 oz line, response is strong among health-conscious energy drink converts.

Serve chilled straight from the can. Pairs well as a morning coffee alternative, pre-workout primer, or early-afternoon focus drink. Store at room temperature; refrigerate before serving.

Common Questions

How does 160mg of caffeine from yerba mate compare to coffee or a standard energy drink?
A standard 16 oz coffee typically delivers 190–260mg of caffeine depending on brew strength, while a Red Bull 16 oz contains about 151mg and a Monster 16 oz contains 160mg — so Yerbaé is in the same ballpark as conventional options. The meaningful difference isn't the milligram count but the co-occurring compounds. Yerba mate leaf naturally contains theobromine (a mild vasodilator also found in dark chocolate) and a range of polyphenols, which many researchers believe modulate how the body absorbs and metabolizes the caffeine. This is why self-reported energy curves from yerba mate tend to be described as more gradual and longer-lasting compared to synthetic caffeine isolates, which spike plasma levels faster. Conventional energy drinks typically use caffeine anhydrous — a dehydrated, isolated form — which has a faster absorption profile and is associated more often with jitteriness and abrupt energy drops.

What exactly is theobromine and why does it matter in an energy drink?
Theobromine is a methylxanthine alkaloid — the same compound family as caffeine — naturally present in yerba mate, cacao, and tea. Unlike caffeine, which primarily blocks adenosine receptors to produce alertness, theobromine acts as a mild bronchodilator and vasodilator, meaning it gently widens blood vessels and airways. Its half-life in the human body is approximately 6–10 hours compared to caffeine's 3–5 hours, which contributes to a more extended, gentler stimulant arc. Theobromine's stimulant potency is roughly 10 times lower than caffeine by weight, so it doesn't dramatically amplify stimulation — instead it rounds off the sharper edge. Because Yerbaé uses whole yerba mate extract rather than isolated caffeine, both compounds are present in their naturally occurring ratio, which is the mechanism most frequently cited when people describe yerba mate energy as feeling cleaner.

Is this drink actually zero carbs and zero sugar, and how is that possible if it has flavor?
Yes — zero sugar, zero calories, and zero carbohydrates are all verified by Yerbaé's Sugar-Free certification and Keto certification, both of which require third-party substantiation beyond self-labeling. The mango passion fruit flavor comes from natural flavor compounds, which are used in extremely small concentrations — typically parts per million — that contribute negligible or no caloric or carbohydrate mass. No artificial sweeteners such as sucralose, aspartame, or acesulfame potassium appear to be used, which is unusual at zero-sugar in the energy drink category where stevia or monk fruit are common workarounds. The Keto certification specifically requires the product to meet ketogenic macro thresholds, confirming it won't trigger an insulin response through hidden sugars or sugar alcohols. This is one of the few energy drinks at 160mg caffeine that achieves this without any sweetener substitution at all.

How do I verify that the Non-GMO and Organic certifications on this product are legitimate?
Non-GMO Project Verified is administered by the Non-GMO Project, an independent nonprofit; products carrying that butterfly label are listed in their publicly searchable product database at nongmoproject.org, where you can confirm Yerbaé's certification status by product name. USDA Organic certification requires annual third-party audits by an accredited certifying agent, and certified products can be verified through the USDA's organic integrity database at apps.ams.usda.gov. Certified Gluten-Free from a recognized body such as GFCO requires testing to below 10 parts per million — a stricter threshold than the FDA's 20 ppm gluten-free labeling standard. Vegan and Keto certifications from recognized certifying organizations also carry defined criteria rather than being self-declared. When a single product carries five or more independent third-party certifications simultaneously, it substantially reduces the risk of front-panel greenwashing because each certification involves separate auditing bodies with their own verification chains.

How does Yerbaé fit into a keto or low-carb diet compared to other energy drinks?
On a standard ketogenic protocol targeting under 20–50g net carbs per day, Yerbaé contributes 0g carbohydrates per 16 oz serving, making it essentially carb-neutral. Most conventional energy drinks — including a standard 16 oz Monster or Rockstar — contain 27–54g of sugar per can, which would consume an entire day's carb budget in a single beverage. Even many 'sugar-free' energy drinks use sugar alcohols like erythritol that some keto practitioners count partially toward net carbs, or sucralose, which some research suggests may blunt ketosis in sensitive individuals. Yerbaé avoids both categories. The Keto certification provides third-party confirmation that the formulation was evaluated against ketogenic dietary standards, not just front-panel calorie math. For someone on keto who still wants a caffeinated functional beverage, this is one of the cleanest options available at the 160mg caffeine tier.

What is yerba mate, and how is it different from green tea or coffee as a caffeine source?
Yerba mate (Ilex paraguariensis) is a species of holly native to subtropical South America — primarily Argentina, Paraguay, Uruguay, and southern Brazil — where it has been consumed as a hot or cold infused beverage for centuries. Its caffeine content per dried leaf is roughly comparable to green tea, but a concentrated extract used in a beverage like Yerbaé is calibrated to a specific final milligram count. Where it differs from both coffee and green tea is in its broader phytochemical profile: yerba mate contains over 196 identified volatile compounds, significant chlorogenic acids (the same antioxidant class prominent in coffee), xanthines including
