It’s rhubarb season, and we’re celebrating it the Sportly Drinking way—with a mocktail that’s not only refreshing and eye-catching, but also packed with benefits for your gut, recovery, and overall performance.

Meet the Rhubarb Sour: a tart, tangy, protein-boosted mocktail that brings the bar vibes without the booze—and adds a serious nutrition bonus.

Why This Mocktail Works for Athletes

The Rhubarb Sour isn’t your average “just-for-fun” drink. Each ingredient was chosen with a purpose—to hydrate, support digestion, promote recovery, and fuel your day (or night) in a functional way.

Let’s break it down:

💖 Rhubarb Juice

Benefits: Rhubarb is high in polyphenols and anthocyanins, known for their anti-inflammatory and antioxidant properties. That means it can help fight oxidative stress from intense training and support muscle recovery.

Rhubarb also promotes gut health. Its natural fiber content and prebiotic effects can support digestion—especially important for athletes dealing with bloating, stress, or a disrupted gut microbiome.

🍋 Fresh Lemon Juice

Benefits: Lemon juice is loaded with vitamin C, which helps boost your immune system and supports collagen production—important for healthy joints, tendons, and skin.

It also has an alkalizing effect, which can help balance acidity levels in the body and support metabolic health, especially after a high-protein or high-carb meal.

🥥 Coconut Water

Benefits: Coconut water is nature’s sports drink. It’s rich in electrolytes like potassium and magnesium—crucial for maintaining hydration and preventing cramps during or after physical activity.

Plus, it’s low in calories and sugar, making it a great option for rehydration without the crash of artificial sports drinks.

🥚 Egg White

Benefits: Egg whites are a clean source of complete protein, providing all essential amino acids with minimal fat and zero sugar.

Using egg white in this mocktail adds a frothy texture and about 3.6g of high-quality protein—perfect for a small recovery boost after a light session or to support muscle repair throughout the day.

(If you’re concerned about raw egg whites, use pasteurized egg whites for safety.)

💪 The Bottom Line

The Rhubarb Sour is more than a pretty mocktail. It’s hydration, gut health, recovery, and a burst of spring energy—all in one glass. It’s perfect as a post-workout refresher, a pre-dinner sip, or your go-to when you want to feel fancy without the hangover.
