What Is Cure Hydration?

Cure launched in 2019 founded by Lauren Picasso with a specific mission: build a hydration drink using the same science as World Health Organization oral rehydration therapy (ORT) — but with clean, natural ingredients instead of artificial sweeteners and dyes.

The base of Cure is organic coconut water powder — a natural source of potassium, magnesium, and trace electrolytes. Each packet is mixed with 8–16 oz of water and delivers electrolytes sourced from real food rather than synthetic mineral salts.

Cure is certified B Corp, non-GMO, and vegan. It is one of the few electrolyte products available at Target, making it widely accessible beyond online-only DTC distribution.

  • Serving size: 1 packet (8g) in 8–16oz water
  • Calories: 25 | Sugar: 4g (organic coconut sugar)
  • Sodium: 310mg | Potassium: 290mg | Magnesium: 35mg
  • No artificial sweeteners, no artificial dyes
  • Price: $2.43/packet (subscription), $2.99 retail

What Is Waterboy?

Waterboy launched in 2020 originally as a hangover recovery drink — that’s where the name comes from. It has since expanded into daily hydration and workout recovery, offering two product lines: Daily Hydration (0 calories, 0 sugar) and Workout Hydration (10 calories, added BCAAs).

Waterboy’s formula sets it apart from most electrolyte drinks by including functional ingredients beyond electrolytes: L-Theanine (for calm focus), Ginger Extract (for digestion and nausea), and Methylcobalamin B12 (the most bioavailable form of B12). It uses Himalayan Sea Salt as its sodium source and zero artificial anything — stevia only for sweetness.

Waterboy has over 10,000 verified customer reviews with a 4.8-star average and a 96% recommendation rate — among the highest of any electrolyte brand in its category.

Ingredient Deep Dive

Sodium: 310mg vs 500mg — Waterboy Wins for Athletes 🏆 Waterboy

Sodium is the electrolyte you lose most of in sweat and the one that drives fluid absorption into your bloodstream. The difference between 310mg and 500mg is not trivial — especially for anyone exercising more than 60 minutes or sweating heavily.

🌿 Cure — 310mg Sodium

Sourced from sodium found naturally in coconut water powder. Appropriate for light activity, daily maintenance hydration, and casual use. Not sufficient as the sole electrolyte source for intense workouts in heat.

💧 Waterboy — 500mg Sodium

Uses Himalayan Sea Salt — a minimally processed salt containing 84+ naturally occurring trace minerals. 500mg is within the ACSM recommended range of 300–600mg/hour for sustained exercise. Better suited for athletes and heavy sweaters.

Potassium: 290mg vs 200mg — Cure Wins 🏆 Cure

Potassium is the electrolyte inside your cells — it works with sodium to maintain fluid balance and is the primary cause of muscle cramps when depleted. Cure’s 290mg edges Waterboy’s 200mg by a meaningful margin. The difference: Cure uses coconut water powder, which is naturally high in potassium. Waterboy uses Potassium Citrate, a synthetic mineral salt.

Both forms are well absorbed, but coconut water also delivers trace minerals not captured on the nutrition label — a real but hard-to-quantify advantage for Cure.

Sugar: 4g vs 0g — Depends on Your Goal

🌿 Cure — 4g Coconut Sugar

Organic coconut sugar is a low-glycemic sweetener with a GI of ~35 vs table sugar’s 65. It provides a small glucose dose that may actually help with ORT-style absorption. Not ideal for keto, strict fasting, or diabetics. Fine for everyone else.

💧 Waterboy — 0g Sugar (Stevia)

Completely zero sugar. Uses organic stevia leaf extract. Safe for keto, intermittent fasting, diabetics, and calorie-restricted diets. Can be consumed multiple times daily without any sugar load accumulating.

Functional Extras — Waterboy’s Biggest Advantage 🏆 Waterboy

This is where the two products most clearly diverge. Cure is a clean electrolyte drink. Waterboy is a functional electrolyte drink.

💧 L-Theanine

An amino acid found naturally in green tea. Promotes calm, focused alertness without sedation. Reduces anxiety and improves cognitive function under stress. Combined with hydration, it supports mental clarity during and after exercise — an effect no other electrolyte in this category provides.

💧 Ginger Extract

A clinically studied anti-nausea and digestive aid. Ginger reduces exercise-induced GI distress, a common issue during intense training. It’s also why Waterboy gained its original reputation as a hangover drink — nausea relief combined with electrolyte replenishment.

💧 Methylcobalamin B12

This is the important detail. Most B12 supplements use cyanocobalamin — a synthetic form the body must convert before it can use. Waterboy uses methylcobalamin, the pre-converted form your body uses directly. Bioavailability is significantly higher. Energy metabolism, nerve function, and red blood cell production all depend on B12 — Waterboy delivers it in the most effective form available.

🌿 Coconut Water Powder

Cure’s unique ingredient. Real coconut water, dehydrated into powder, retains natural trace minerals beyond just the five listed on the label. Acts as a gentle whole-food electrolyte base rather than isolated synthetic salts. No specific functional benefit beyond electrolytes, but the natural sourcing is real.

Price Per Electrolyte Milligram — The Real Cost Math

Most comparisons stop at price per packet. Here is the calculation that actually matters:

Metric 🌿 CURE 💧 WATERBOY
Price per packet (sub)$2.43$2.25
Total electrolytes per packet635mg750mg
Cost per 100mg electrolytes$0.383$0.300 ✓
Annual cost (1/day, sub)$887$821
Annual cost (5x/week, sub)$632$585

Waterboy delivers electrolytes at 22% lower cost per milligram than Cure. Over a year of daily use, that difference is $66 — and Waterboy also includes L-Theanine, Ginger, and B12 at that lower per-mg cost. On pure value math, Waterboy wins.

Who Should Buy Which?

🌿 Choose Cure if:

  • You want a natural, whole-food-based electrolyte source
  • You are buying for children or the whole family
  • Coconut water’s natural potassium profile appeals to you
  • You do light to moderate activity (yoga, walking, office hydration)
  • You want something available at Target without ordering online
  • A small amount of natural sugar (coconut sugar) is fine for your diet
  • B Corp certification and ethical brand values matter to you

💧 Choose Waterboy if:

  • You work out intensely or sweat heavily (higher sodium dose)
  • You need zero sugar — keto, fasting, diabetic, or cutting calories
  • You want added functional benefits (L-Theanine, Ginger, B12)
  • You want hangover recovery support built into your electrolyte drink
  • You want the most bioavailable form of B12 (methylcobalamin)
  • You train for more than 90 minutes and need real electrolyte replacement
  • Budget matters — 22% cheaper per electrolyte milligram

Neither is right for extreme endurance (3+ hours): Consider LMNT or SiS for ultra-endurance events. Both Cure and Waterboy are designed for 60–90 minute sessions. For sustained multi-hour output, you need higher sodium doses (1,000mg+).

Frequently Asked Questions

It depends on your use case. Cure is better for natural ingredient sourcing, higher potassium (290mg vs 200mg), and clean family-friendly hydration. Waterboy is better for athletes — higher sodium (500mg vs 310mg), zero sugar, and functional extras like L-Theanine and Ginger Extract. Cure scores 78/100 vs Waterboy’s 74/100 on DTCetc, reflecting its cleaner ingredient profile. But for performance hydration, Waterboy’s formula is stronger.
Waterboy was originally designed as a hangover recovery drink — its combination of sodium (500mg), Ginger Extract (anti-nausea), and L-Theanine (calm focus) specifically targets the three worst hangover symptoms: dehydration, nausea, and foggy thinking. Cure will help with electrolyte replenishment but lacks the Ginger and L-Theanine that make Waterboy effective for hangover recovery specifically.
Technically yes, but marginally so. Cure contains 4g of coconut sugar per packet — low-glycemic (GI ~35), but still 4g of carbohydrates. For strict keto dieters who track macros carefully, this counts. Waterboy (0g sugar, 0g carbs) is the clearly keto-safe choice. If you’re on a flexible or dirty keto approach, Cure’s 4g coconut sugar per packet is unlikely to knock you out of ketosis.
Both brands recommend 8–16oz (237–473ml) per packet. Standard is 12oz (355ml). More water = weaker electrolyte concentration per ml but same total electrolytes per serving. Use the calculator above to see exactly how concentration changes with water amount. For exercise, 12oz is ideal. For gentle daily sipping throughout the morning, 16oz works well.
Yes, but it depends on the context. During a long, intense workout (90+ minutes in heat), 2 Waterboy packets delivering 1,000mg sodium is well within safe and effective range. For casual daily hydration, one packet is plenty. Use the calculator above to see doubled nutrition values and decide if that dose makes sense for your activity level. Neither brand lists a maximum dose, but exceeding 2,000mg sodium from electrolyte packets in one session is not recommended without medical guidance.
Waterboy’s zero-sugar formula and clean ingredients are generally safe for children over 5 during active sport. However, its 500mg sodium per packet and the presence of L-Theanine mean it’s designed for adults. Cure is the better children’s choice — lower sodium, coconut water base, and no functional actives that aren’t appropriate for younger users. Cure is also available at Target and has positioned itself toward family hydration.
Waterboy built its following primarily through social media and its hangover recovery positioning — not through supplement review channels or sports nutrition publications. Most “best electrolyte drink” lists were written 2–4 years ago and anchor to established brands. Waterboy’s 4.8-star average across 10,000+ verified reviews and 96% recommendation rate suggest the product is well-regarded by real users, regardless of its visibility in review articles.
