Homemade Sports Drink Recipe Calculator
A homemade endurance sports drink uses maltodextrin and fructose in a 2:1 ratio at 60-90g carbs per hour, 500-1,000mg sodium from sodium citrate, and 6-8% total concentration to stay isotonic. This is the same active formula as Maurten 320, SiS Beta Fuel, and Tailwind, at $0.30-$0.50 per bottle versus $3-$5 commercial.
Inputs map to published research on glucose-fructose co-ingestion (Jeukendrup 2010, 2014), sweat sodium variability (Baker et al. 2016), and gastric osmolarity tolerance. Results are a calibrated starting point, not a medical prescription. Validate against your own training data and adjust for race conditions.

Not Medical Or Nutrition Advice
This calculator and the resulting plan are educational only. Endurance sports carry inherent risks and individual nutrition needs vary. Athletes should consult a qualified healthcare professional or a registered sports dietitian before applying any nutrition, hydration, or supplementation strategy, especially if you have a medical condition, are pregnant, take medications, or are training through injury. Use this information at your own risk.

Homemade Sports Drink: Common Questions
A homemade sports drink using maltodextrin, fructose, and sodium citrate performs identically to Maurten 320 and SiS Beta Fuel on the key metabolic metrics (carb absorption ceiling, gut tolerance, electrolyte replacement), costs $0.30-$0.50 per bottle instead of $3-$5, and lets you dial sodium precisely to your sweat rate.
Is a homemade sports drink as effective as Maurten or SiS Beta Fuel?
For the carbohydrate side, yes. Maltodextrin and fructose are the only two active ingredients doing the metabolic work in nearly every commercial endurance fuel. The published carb-absorption ceilings (up to 90g per hour at 2:1 glucose to fructose, up to 120g per hour at 1:0.8) come from research using exactly those two molecules. The commercial premium pays for convenience, flavor masking, hydrogel encapsulation, and brand. The biochemistry is the same.
How much money does a DIY sports drink save vs commercial brands?
A standard 60g per hour mix costs roughly $0.30 to $0.50 per bottle in bulk powder versus $3 to $5 per serving for commercial fuel. An athlete training 8 hours per week with 3 to 4 race days per year typically saves $1,200 to $4,000 per year. The calculator runs a personalized cost audit based on your actual training volume and current commercial brand.
What carb ratio should I use for a homemade endurance drink, 2:1 or 1:0.8?
Use 2:1 glucose to fructose (maltodextrin plus fructose) for intake at or below 70g per hour. Use 1:0.8 (closer to equal parts) for intake above 70g per hour up to 120g per hour. The 1:0.8 ratio recruits more fructose transporters and pushes total absorption higher, but the ceiling only applies to athletes with a trained gut. Sensitive athletes should stay at 2:1 regardless of target rate.
Will a homemade sports drink taste different from commercial options?
Plain DIY tastes like sweet water with no flavor masking. The calculator includes 7 dry-powder flavor profiles using shelf-stable citric acid, natural flavor extracts, freeze-dried berry powder, ginger root powder, and savory options for ultra-distance. Sodium citrate is also dramatically less briny than table salt at high-sodium doses, so you can hit 800 to 1,200 mg per hour without the throat-burn that pure NaCl creates.
Can a homemade sports drink hit precision sodium dosing of 1,000 mg per hour?
Yes, with a $15 jewelers scale that reads to 0.1g. 1g of sodium citrate delivers about 270 mg sodium, so 1,000 mg per hour equals about 3.7g of sodium citrate per bottle. That is well within the resolution of any kitchen scale. The calculator returns the exact gram weight for both NaCl and sodium citrate based on your hourly target.
Is bulk maltodextrin safe and food-grade for a homemade sports drink?
Yes, when sourced from a reputable bulk supplements brand. Look for NSF or Informed Sport certification on the label, and confirm the product is labeled USP or food-grade. The calculator routes Amazon links to vendors that meet these criteria.
