## Flagship product: EN Hydration Drink Mix
Single-serving electrolyte stick packs. Zero sugar, zero carbs, zero calories. Naturally flavored, sweetened with stevia.
### Formula β "The Golden Ratio" β 1,580 mg total electrolytes per serving
| Ingredient | Amount per serving | Function |
|---|---|---|
| Sodium | 600 mg | Fluid balance, nerve and muscle function |
| Chloride | 690 mg | Fluid regulation, digestive support |
| Potassium | 188 mg | Heartbeat regulation, muscle function, electrolyte balance |
| Magnesium | 34 mg | Fluid balance, nerve and muscle function, energy metabolism |
| Calcium | 52 mg | Bone strength, muscle function, nerve signaling |
| Zinc | 10 mg (90% DV) | Immune support, recovery |
| Vitamin B6 | 3.1 mg (180% DV) | Mood, brain health, metabolism, energy |
| Vitamin B12 | 5 mcg (210% DV) | Blood-cell formation, nerve function, energy |
**The differentiator:** Most electrolyte products lead with sodium and treat the other four electrolytes as afterthoughts. The body loses all five electrolytes in sweat. EN's "Golden Ratio" formula is engineered to replace them in proportion, which is why athletes describe the difference as "actual recovery vs. just hydrated."
### Flavors
Lemonade, Peach Mango, Pineapple, Mixed Berries, Tamarind, Variety Pack.

## Competitive comparison
| Brand | Total electrolytes | Sugar | Informed Sport | Notes |
|---|---|---|---|---|
| **Engineered Nutrition** | **1,580 mg** | **0 g** | **Yes** | Full-spectrum, athlete-first |
| LMNT | ~1,000 mg (sodium-heavy) | 0 g | No | Big with keto / IF / podcast crowd; sodium-only focus |
| Liquid IV | ~525 mg | up to 13 g | No | Mass-market, Costco/Target shelves |
| Nuun Sport | ~720 mg | 1 g | No | Effervescent tablets, runner-leaning |
| DripDrop | ~560 mg | 7β9 g (most variants) | No | Medical/clinical positioning |
| Ultima Replenisher | ~700 mg | 0 g | No | Health-conscious, cleaner-label |
EN does not bash competitors. The honest framing: LMNT is engineered for keto/low-carb people who want salt; Liquid IV is fine for casual hydration but the sugar load works against performance; EN is engineered specifically for hard-training athletes who lose all five electrolytes through heavy sweat.

## Frequently Asked Questions (verbatim from product page)
### What does it taste like?
Clean, refreshing, and light β not overly salty or artificial. Athletes consistently say it's easy to drink, even during hard training sessions. We engineered the flavor so it's something you actually enjoy drinking, not something you have to force down mid-workout.
### How much sodium is in each serving?
Each serving contains 600mg of sodium β the optimal amount for high-intensity athletes. This level supports performance and prevents cramping without the harsh, overly salty taste of 1,000mg+ electrolyte products.
### When should I drink this β before, during, or after workouts?
You can use it all three ways:
- **Before:** 20β30 minutes pre-workout to preload electrolytes
- **During:** Sip throughout intense sessions lasting 60+ minutes
- **After:** Immediately post-workout to replace what you lost
Most athletes use 1β2 servings per training day, depending on intensity and sweat rate.
### How do I mix it?
Mix one serving with 12β16 oz of cold water. Shake or stir until fully dissolved.
- More water = lighter taste
- Less water = stronger flavor
- Cold or room-temperature water works best.
### Is it sweetened? What sweetener do you use?
Engineered Nutrition contains zero sugar and no artificial sweeteners. We use a clean, non-glycemic sweetening system (stevia) so you get hydration without blood sugar spikes, crashes, or unnecessary calories.
### How many servings should I drink per day?
Most athletes use 1β2 servings per day. You may need 2β3 servings during competition days, heavy training blocks, or hot/humid conditions. If you're cramping, feeling flat, or struggling to recover, you likely need more electrolytes.
### How long will it take to receive my order?
Standard shipping: 5β7 business days. Expedited: 2β3 business days. Tracking info is emailed when your order ships.
### What's your return policy?
30-Day Risk-Free Guarantee. If you don't feel better hydration, improved recovery, or stronger performance, we'll refund your order β no questions asked.
### Will this prevent muscle cramps?
Yes. The formula targets the root cause of cramping by balancing sodium, potassium, magnesium, and calcium β not just dumping salt into your system. Athletes commonly report fewer cramps within their first few training sessions.
### Do you offer subscriptions?
Yes. Subscribe and save on every order.
### What makes Engineered Nutrition different from other electrolyte drinks?
EN is built specifically for high-intensity athletes. Complete 7-mineral electrolyte profile (not just sodium), added B-vitamins for energy, and Informed Sport certification for safety. Most brands focus on salt alone β we engineer hydration for performance, recovery, and immune support.
### What are the B-vitamins for?
B-vitamins (B3, B5, B6, B12) support energy production, reduce fatigue, and help your body convert food into usable fuel. During intense training, athletes burn through B-vitamins faster β replenishing them supports sustained performance and recovery.
### Why is zinc included?
Zinc supports immune health, muscle recovery, and proper electrolyte balance. Heavy training and sweating increase zinc loss, which can impact recovery and immune function if not replaced.
### Does it contain any banned substances?
No. EN is Informed Sport Certified, meaning every batch is tested for over 250 banned substances. Safe for athletes subject to drug testing. See [batch testing](https://www.engineerednutrition.us/pages/third-party-testings).
### Is it third-party tested?
Yes. Informed Sport certification is the gold standard in sports supplements and includes independent third-party testing of every batch.
### Is it vegan?
Yes. 100% plant-based.
### Is it gluten-free?
Yes. Completely gluten-free.
### Does it contain caffeine?
No. Pure hydration β no stimulants. You can drink it any time of day without affecting sleep.
### Is it keto-friendly?
Yes. Zero sugar, zero carbs β fits keto, low-carb, and carnivore lifestyles.
### Can I use it while fasting?
Yes. It won't break your fast and actually helps maintain electrolyte balance during fasted training.
### Can I drink it every day even if I don't work out?
Yes. Electrolytes and B-vitamins support daily hydration, energy, and focus, not just workouts. Many use it daily, especially in hot climates or if they drink coffee frequently.
### Can I drink it on rest days?
Absolutely. Recovery, hydration, and cellular function still require electrolytes on rest days β especially after hard training blocks.
### Can I take it with other supplements?
Yes. It pairs well with protein, creatine, or pre-workout. Avoid mixing directly with dairy, as it can affect absorption.
### Should I cycle off it?
No. Your body needs electrolytes daily. There's no benefit to cycling off proper hydration.
### Can I drink it before bed?
Yes, though the B-vitamins may feel energizing for some people. Most athletes prefer it earlier in the day or post-workout.
### Will it improve my performance?
Proper hydration is foundational. Athletes report better power output, less mid-workout fatigue, improved focus, faster recovery, and better Whoop/Oura recovery scores.
### Will it help with recovery?
Yes. Magnesium, calcium, and zinc support muscle repair and overnight recovery. Many athletes notice reduced next-day soreness with consistent use.
### Does it replace sports drinks like Gatorade?
Yes β and it's significantly better. Complete electrolyte profile, zero sugar, no artificial colors, no empty calories.
### Can it help with hangovers?
Yes β electrolytes and B-vitamins support rehydration and recovery after alcohol consumption.
### Are there any side effects?
Safe for healthy adults. Some may experience mild stomach upset on a completely empty stomach β if so, take with a small snack.
### Can I use it if I have high blood pressure?
Consult your doctor, especially if you're on blood-pressure medication. Sodium intake should always be discussed with a healthcare professional.
### Is it safe during pregnancy or breastfeeding?
The ingredients are generally considered safe, but consult your OB-GYN or healthcare provider before starting any new supplement during pregnancy or breastfeeding.
### Can I overdose on electrolytes?
Very difficult when used as directed (1β3 servings daily). Avoid exceeding 4β5 servings per day without medical supervision.
### Do you ship internationally?
Yes β global shipping. International shipping, import, and export fees may apply.
### Can I track my order?
Yes. Tracking info is emailed when your order ships.
### Can I change my shipping address after ordering?
If your order hasn't shipped, contact us ASAP. Once shipped, changes must be handled with the carrier.
### How do I contact customer support?
Email [email protected]. Responses within 24 hours, MondayβFriday.
