Most "sports drinks" are sugar water with a pinch of salt. SUSTAIN is built for endurance work that actually depletes you — 24g of fast-absorbing carbohydrates from a dextrose + glucose-polymer (maltodextrin) blend, plus a 200mg electrolyte blend of sodium chloride, potassium citrate, magnesium citrate, and calcium carbonate.
100 calories, 12g sugar, no artificial colors. The carb blend refills muscle glycogen during long sessions; the electrolyte blend replaces what you sweat out. One rounded scoop into 8 oz of cold water during or after your workout. Available in Lemon Lime and Summer Punch.
- ✓24g fast-absorbing carbs (dextrose + maltodextrin) — supports normal glycogen replenishment during long training
- ✓200mg electrolyte blend — sodium, potassium, magnesium, and calcium to replace what's lost in sweat
- ✓100 calories per serving — fuel for the work, not a sugar crash after
- ✓50 servings per container — built for athletes who train daily, not sip a sports drink twice a month

Is this right for you?
- ✓You train longer than 60 minutes — endurance athletes, runners, cyclists, hot-weather lifters
- ✓You sweat heavily and need real electrolyte replacement, not flavored water
- ✓You want intra-workout carbs to keep glycogen topped off in long sessions
- ✓You want a sports drink that's transparent on doses, not a proprietary blend
- ✗You're cutting or in a calorie deficit — 24g carbs intra-workout works against fat loss for short sessions
- ✗Your training is < 45 min — water and a pre-workout meal cover most short-session needs
- ✗You avoid sucralose or artificial flavors (SUSTAIN contains both)
- ✗You only need electrolytes (no carbs) — a calorie-free EAA + electrolyte product fits better
How to use it
Intra-workout: Mix 1 rounded scoop (27.3g) into 8 oz of cold water. Sip throughout sessions longer than 60 minutes — long runs, rides, hot-weather training, two-a-days.
Post-workout: Mix as above immediately after training to start glycogen replenishment and replace electrolytes lost in sweat.

Frequently asked questions
How is SUSTAIN different from EAAs + Hydration?
SUSTAIN is a carb + electrolyte fuel for long endurance work — it gives you energy. EAAs + Hydration is calorie-free amino acids + electrolytes for muscle preservation in fasted or low-carb states. Cutting? EAAs. Long ride or run? SUSTAIN.
When during a workout should I sip it?
For sessions over 60 minutes, sip steadily from minute 30 onward. For shorter sessions, take it post-workout to start glycogen replacement. On hot days or two-a-days, a serving between sessions speeds recovery and rehydration.
Can I stack SUSTAIN with other MaxWell supplements?
Yes. Common stacks: PERFORM pre-workout, SUSTAIN intra, and Whey Isolate post for recovery. Creatine can be mixed directly into your SUSTAIN bottle.
Does SUSTAIN have artificial sweeteners or colors?
SUSTAIN is sweetened with sucralose and uses natural and artificial flavors. No artificial colors are listed. If you avoid sucralose, this product isn't a fit — there's no stevia version.
