Precision Batch & Serving Calculator
Select your batch size (1 to 60+ servings), bottle water volume, and session carbohydrate mode. All weights are computed to 0.01 g precision.
Adjusts concentration & live osmolarity (mOsm/L) per bottle.
Live Osmolarity Telemetry: ~181 mOsm/L
38% lower tonicity than human blood plasma (285–295 mOsm/L) — drives rapid osmotic water absorption across the small intestine with zero stomach sloshing.

Why the Math Works Under Heavy Barbell Loads
Designed for rapid duodenal transit during high intra-abdominal pressure (IAP) bracing
Hypotonic Osmolarity (~175–185 mOsm/L)
Commercial sports drinks fail during heavy squats and deadlifts because they are hypertonic (300–350+ mOsm/L) relative to human blood plasma (285–295 mOsm/L). High sugar density pulls water out of tissues into the gut lumen, delaying gastric emptying and causing GI bloat and stomach sloshing under a lifting belt.
SGLT1 Cotransport Precision
The Sodium-Glucose Linked Transporter (SGLT1) in the intestinal brush border is an active symporter that requires a strict stoichiometric ratio of 2 Sodium ions (Na⁺) to 1 Glucose molecule to pump solute—and ~260 water molecules per cycle—directly into plasma.
Provides a deliberate molar surplus of pure D-glucose to saturate every Na⁺ transporter on contact while capping calories at just 60 kcal.
5:1 Na:K Ratio & Magnesium Malate
5:1 Sodium-to-Potassium (1,000 mg : 200 mg) mirrors human sweat losses and preserves the Na⁺/K⁺-ATPase resting membrane potential across skeletal muscle fibers during high-RPE sets.
- ✕ No Oxide / Citrate: Avoids osmotic laxative pull and mid-workout GI cramping.
- ✕ No Glycinate Pre-Lift: Avoids inhibitory glycine neurotransmission / sedation during training.
- ✓ Malic Acid Synergy: Direct Krebs cycle intermediate for ATP regeneration + tart citrus flavor pairing with True Lime.

Ingredient Sourcing & Equipment Specification Guide
Every raw material is selected for pharmaceutical purity, rapid cold-water dissolution, and zero gastrointestinal side effects.
0.01g High-Precision Digital Pocket Scale
Mandatory for sub-gram accuracy: Standard 1g kitchen scales cannot measure 0.39 g of KCl or Magnesium Malate. Select a 0.01 g jewelers/pocket scale bundled with a 100g calibration weight.
NOW Foods Pure Dextrose Powder
100% pure D-glucose monohydrate: Directly binds to intestinal SGLT1 transporters without requiring enzymatic hydrolysis. Contains zero fructose (which requires hepatic metabolism via GLUT5 and slows gastric transit).
Redmond Real Salt (Ancient Fine Sea Salt)
Unrefined ancient seabed salt: Zero chemical anti-caking agents (no sodium silicoaluminate), zero metallic potassium iodide aftertaste, and a fine grain crystal structure for rapid dissolution.
BulkSupplements Potassium Chloride Powder
~52% elemental potassium by weight: Pure USP-grade KCl powder with zero fillers or flow agents. Delivers 200 mg elemental K⁺ in just 385 mg of total powder while contributing chloride ions.
BulkSupplements Magnesium Malate Powder
~15% elemental magnesium by weight: Highly bioavailable chelate bound to malic acid. Prevents muscle cramping without GI distress or CNS drowsiness.
True Lime Crystallized Lime Packets
Citric acid + cold-pressed lime oils: Cuts the heavy salinity of 1,000 mg sodium into a crisp, refreshing limeade profile with 0 calories, zero sugar, and zero artificial sweeteners or dyes.
Step-by-Step Mixing & Bulk Prep Protocol
Start with 8–10 oz Room-Temperature Water
Add 8 to 10 oz of room-temperature water to your 32 oz bottle first. Crystalline powders and chelated minerals dissolve significantly faster before ice is introduced.
Tare & Weigh on 0.01g Digital Scale
Place a small weighing cup on your 0.01g scale, press TARE, and weigh out: 15.00 g Dextrose (or 25.00 g fasted), 2.50 g Redmond Real Salt, 0.39 g Potassium Chloride, and 0.39 g Magnesium Malate (Total dry base: 18.28 g).
Add True Lime & Agitate 15–20 Seconds
Pour the weighed powders and 1 to 2 packets of True Lime (0.80 g – 1.60 g) into the bottle, secure the lid, and shake vigorously for 15 to 20 seconds until dissolved.
Top to 32 oz with Cold Water & Ice
Fill to the 32 oz (~950 mL) mark with cold filtered water and ice, then give one final swirl. Begin sipping 10 minutes prior to your first warm-up set.
A slight reddish-pink mineral sediment settling at the bottom of your bottle is completely normal—it is harmless natural trace bentonite clay and iron oxide inherent to unrefined Redmond Real Salt. Simply swirl the bottle before your final sip.
Never Dump Trace Minerals Directly Into 450g of Dextrose
Because Potassium Chloride (11.6 g) and Magnesium Malate (11.7 g) represent only ~4.2% of the total bulk weight, dumping everything into a large tub at once can cause uneven mineral hotspots. Use 2-stage geometric dilution:
- Stage 1 (Electrolyte Premix): In a clean, dry 16 oz mason jar, combine 75.0 g Redmond Real Salt, 11.6 g Potassium Chloride, and 11.7 g Magnesium Malate with ~50.0 g of Dextrose. Seal and shake/tumble vigorously for 60 seconds until uniform.
- Stage 2 (Bulk Integration): Add the remaining 400.0 g of Dextrose into your airtight bulk tub, pour in the Stage 1 premix, seal, and tumble/whisk thoroughly for 90 seconds.
- Dosing per Workout: Tare your bottle or scoop on a scale and measure out 18.28 g of the bulk powder + 1–2 packets of True Lime.
Store the bulk powder in an airtight container with a food-grade silica desiccant packet. Keep the True Lime packets separate in their foil wrappers until the moment of drinking—citric acid and dextrose monohydrate are hygroscopic and will pull ambient humidity to cake into a solid brick if pre-mixed in bulk.
