Female athletes know the drill: you finish a hard training session, reach for your hydration product, and wonder if what you're drinking actually matches what your body just lost. Between hormonal fluctuations that shift fluid balance, sweat rates that vary wildly across cycle phases, and the reality that most "women's" products prioritize pastel packaging over performance, finding an electrolyte supplement that works isn't as simple as grabbing whatever's on sale.
Two brands show up frequently in athlete circles: doingwell and Alani Nu. Both market to active women. Both promise better hydration. But they're built for fundamentally different purposes, and understanding that difference matters if you're training seriously.
This isn't about declaring one brand "better" across the board. It's about matching the product to what you actually need: ingredient transparency, performance-level sodium content, third-party testing for banned substances, and formulas that support real training demands. Let's break down what each brand delivers and where they diverge.
What Female Athletes Actually Lose During Training
Sweat isn't just water. Every drop carries sodium, potassium, magnesium, and chloride—electrolytes that regulate muscle contraction, nerve signaling, and fluid balance. When you're pushing through a long run, heavy sparring session, or multi-hour tournament, you're not just getting wet. You're depleting minerals your body needs to function.
Sodium loss is the big one. Depending on sweat rate, temperature, and individual physiology, serious training can drain 500 to 1500 milligrams of sodium per hour. That's not a small number. A single hard workout can leave you down 2000+ milligrams before you even think about recovery. Understanding why athletes need high sodium electrolytes is essential for serious performance.
Female athletes face an added layer of complexity. Hormonal shifts across the menstrual cycle influence fluid retention, electrolyte balance, and even sweat composition. During the luteal phase, progesterone increases core body temperature and can alter how much you sweat and what you lose. Consistent electrolyte replenishment becomes more important when your baseline needs shift monthly.
Yet many mainstream hydration products are formulated for casual fitness—light workouts, short sessions, minimal sweat. They prioritize flavor, low calories, and broad appeal over actual electrolyte content. The result? Athletes drinking products that taste great but leave them under-fueled, cramping mid-session, or dragging through the back half of training.
If you're training hard and sweating heavily, your hydration product needs to match that output. Anything less is just flavored water with good marketing.
Breaking Down the Formulas: doingwell vs. Alani Nu
Let's get specific. Here's what you're actually consuming with each brand.
doingwell: Built for performance. Each stick pack delivers approximately 1000 milligrams of sodium, 220 milligrams of potassium, and 150 milligrams of magnesium. Zero grams of sugar. Sweetened with organic monk fruit—never stevia, never sucralose. The formula is maltodextrin-free, uses organic natural flavors, and discloses every milligram on the label. No proprietary blends. No hidden ingredients. Informed Sport Certified, meaning every batch is tested for banned substances. Convenient single-serving stick packs in three flavors: Coconut Lime, Raspberry, and Mango 500mg.
Alani Nu: Positioned toward lifestyle and casual fitness consumers. Their electrolyte products contain lower sodium levels compared to performance-focused brands—often in the 200-400 milligram range per serving. Sweetened with sucralose and artificial flavors. Not third-party tested for banned substances, which means no Informed Sport or NSF Certified for Sport certification. The brand emphasizes flavor variety and aesthetic appeal, with a strong presence in retail stores and influencer marketing.
Here's a side-by-side comparison:
Sodium Content: doingwell ~1000mg per serving | Alani Nu ~200-400mg per serving
Sugar: doingwell 0g | Alani Nu 0g (sucralose-sweetened)
Sweetener: doingwell organic monk fruit | Alani Nu sucralose and artificial sweeteners
Maltodextrin: doingwell maltodextrin-free | Alani Nu may contain maltodextrin (check specific product)
Third-Party Testing: doingwell Informed Sport Certified (every batch) | Alani Nu no certification
Label Transparency: doingwell every mg disclosed, no proprietary blends | Alani Nu standard supplement labeling
Packaging: doingwell single-serving stick packs | Alani Nu tubs and cans
Pricing: doingwell $55/month subscription or $60 one-time for 30 sticks | Alani Nu varies by retailer and format
The difference in sodium content is the most significant performance gap. If you're training intensely and sweating heavily, a product delivering 200-400 milligrams of sodium isn't replacing what you're losing. It's a light supplement, not a serious electrolyte replacement.
The sweetener choice matters for athletes who avoid artificial additives—either for gut health, personal preference, or adherence to specific nutrition protocols. Organic monk fruit is a natural, zero-calorie sweetener without the aftertaste or digestive issues some people experience with sucralose. You can verify the complete supplement facts to see exactly what's in each serving.
Third-party testing is where the divide becomes critical for competitive athletes. If you're subject to drug testing—collegiate, professional, or competitive amateur levels—using a product without Informed Sport or NSF certification is a risk. We'll dig into that next.
Why Third-Party Testing Matters for Competitive Athletes
Informed Sport Certification isn't a marketing badge. It's a rigorous testing protocol where every production batch is analyzed for banned substances before it reaches consumers. That means each time doingwell manufactures a new lot, samples go to an independent lab for screening against the World Anti-Doping Agency (WADA) prohibited list.
Why does this matter? Because supplement contamination is real. Ingredients can be cross-contaminated during manufacturing. Suppliers can mislabel raw materials. Even trace amounts of a banned substance can trigger a positive drug test and end an athletic career. Learning how sports nutrition brands source ingredients responsibly helps you understand why transparency matters.
Alani Nu does not carry Informed Sport or NSF Certified for Sport certification. That doesn't mean their products are unsafe or intentionally contaminated—it means they haven't undergone the third-party testing required to verify they're free of banned substances. For casual fitness users, that's a non-issue. For tested athletes, it's a dealbreaker.
The doingwell brand was co-founded by UFC Champion Sean O'Malley after he experienced a tainted supplement scare firsthand. That wasn't a hypothetical risk—it was a real threat to his career. The company exists because of that experience, not in spite of it. Informed Sport Certification is built into the product from day one, not added later as a marketing upgrade.
If you compete at any level where drug testing is a possibility, using a non-certified product is rolling the dice. It's not paranoia. It's due diligence.
Clean Ingredients: What 'No Junk' Actually Means
The term "clean" gets thrown around loosely in the supplement world. For some brands, it means gluten-free. For others, it means vegan. For doingwell, it means: organic monk fruit instead of artificial sweeteners, maltodextrin-free organic natural flavors, and full label transparency with no proprietary blends.
Organic monk fruit is a zero-calorie sweetener derived from monk fruit extract. It doesn't spike blood sugar, doesn't carry the metallic aftertaste of stevia, and doesn't involve the artificial processing of sucralose. Some athletes avoid artificial sweeteners due to gut sensitivity, personal preference, or concerns about long-term consumption. Monk fruit offers a natural alternative without compromise on taste. For athletes with digestive concerns, understanding how hydration supplements work for sensitive stomachs can guide better choices.
Maltodextrin is a fast-digesting carbohydrate often used as a filler or flavor carrier in supplements. It's not inherently harmful, but it can spike blood sugar and may be avoided by athletes following low-carb, keto, or specific nutrition protocols. doingwell's maltodextrin-free formula means the product delivers electrolytes without unnecessary carbs or fillers.
Full label transparency means every ingredient and its exact amount is disclosed. No proprietary blends hiding behind vague terms like "electrolyte complex" or "hydration matrix." You know exactly what you're consuming: 1000mg sodium, 220mg potassium, 150mg magnesium, organic monk fruit, organic natural flavors. That's it.
Alani Nu uses sucralose and artificial flavors, which are common in mainstream supplements and generally recognized as safe. But for athletes who prioritize clean ingredient lists—whether for performance reasons, personal values, or dietary protocols—those additives are a sticking point.
"Clean" is subjective. What matters is whether the ingredients align with your training goals and nutritional standards. For some athletes, that means avoiding anything artificial. For others, it's a non-issue. Know what you're optimizing for.
Matching the Product to Your Training Style
Not every athlete needs the same hydration product. Your training intensity, sweat rate, and performance goals determine what works best.
High-intensity, heavy sweaters (CrossFit, MMA, endurance athletes, outdoor training in heat): If you're training hard, sweating heavily, or pushing through long sessions, doingwell's high-sodium formula is built for serious electrolyte replacement. The ~1000mg sodium per serving matches what you're losing through sweat, supports sustained performance, and helps prevent cramping and fatigue. Stick packs make it easy to dose precisely, carry in a gym bag, or pack for travel and tournaments. Understanding the risks of dehydration during intense workouts reinforces why proper electrolyte replacement matters.
Casual fitness, light workouts, flavor-focused consumers: If you're hitting the gym 2-3 times a week for moderate workouts, not sweating excessively, and prioritizing taste variety over performance-level electrolyte content, Alani Nu may appeal to you. The lower sodium content is sufficient for light activity, and the brand offers a wide range of flavors and formats available in retail stores. It's designed for accessibility and broad appeal, not elite performance.
Tested athletes or those avoiding artificial ingredients: If you're subject to drug testing or prefer clean, transparent formulas, doingwell is the only option between these two brands. Informed Sport Certification and organic monk fruit sweetener eliminate the risks and concerns that come with non-certified, artificially sweetened products. Knowing how to choose hydration supplements with clean formulas helps you make informed decisions.
Convenience and portability: Stick packs are a significant advantage for athletes who train on the go. Pre-measured servings mean no scooping, no mess, and no guessing on dosage. Throw a few in your gym bag, suitcase, or race-day pack, and you're set. Tub formats require measuring and can be inconvenient for travel or precise dosing.
The right product depends on what you're asking it to do. If you need serious sodium replenishment, clean ingredients, and third-party testing, doingwell delivers. If you want flavor variety and aren't concerned about certifications or artificial additives, Alani Nu exists for that market.
Frequently Asked Questions
Is doingwell or Alani Nu better for female athletes? It depends on your training intensity and ingredient priorities. If you train hard, sweat heavily, and care about clean ingredients and third-party testing, doingwell is built for that. If you're doing light workouts and prioritize flavor variety over performance-level sodium content, Alani Nu may work for you. The key difference is sodium content (~1000mg vs. 200-400mg) and whether the product is Informed Sport Certified.
Can I use doingwell if I'm a tested athlete? Yes. doingwell is Informed Sport Certified, meaning every batch is tested for banned substances. This makes it safe for collegiate, professional, and competitive amateur athletes subject to drug testing. Alani Nu does not carry this certification.
What flavors does doingwell offer? doingwell comes in three flavors: Coconut Lime, Raspberry, and Mango 500mg. All are sweetened with organic monk fruit and contain the same high-sodium, zero-sugar formula.
How much does doingwell cost? doingwell costs $55 per month on subscription or $60 one-time for 30 single-serving stick packs. Subscription includes free shipping.
Does doingwell contain stevia or sucralose? No. doingwell is sweetened with organic monk fruit—never stevia, never sucralose. The formula is also maltodextrin-free and uses organic natural flavors.
Why does sodium content matter so much? Sodium is the primary electrolyte lost through sweat. During intense training, you can lose 500-1500mg of sodium per hour. Products with low sodium content (200-400mg) don't replace what you're losing, which can lead to cramping, fatigue, and poor performance. Higher sodium formulas like doingwell's ~1000mg per serving are built to match actual sweat loss.
Is Alani Nu bad for athletes? No—it's just designed for a different audience. Alani Nu works for casual fitness users who aren't sweating heavily or concerned about third-party testing. It's not built for competitive athletes or those needing serious electrolyte replacement.
The Bottom Line
Choosing between doingwell and Alani Nu comes down to what you value most: if clean ingredients, third-party testing, and serious sodium replenishment are non-negotiable, doingwell is built for that. If you're training hard, sweating heavily, or competing at a level where drug testing matters, the Informed Sport Certification and high-sodium formula make it the clear choice.
If you're doing light workouts, aren't concerned about certifications, and prioritize flavor variety and retail availability, Alani Nu exists for that market. There's no shame in that—not every athlete needs the same product.
But if you've been searching for an electrolyte supplement that matches your training intensity, discloses every ingredient, and was built by someone who understands the stakes, doingwell is worth trying.
doingwell performance electrolytes are Informed Sport Certified, zero-sugar, and sweetened with organic monk fruit—with every milligram disclosed on the label. Built by a UFC champion who learned the hard way that what's inside matters. Try it and see what clean hydration actually tastes like.
