The Science
Built for thenext 40 years.
Most gels engineer for the next 90 minutes. We engineer for the next 40 years. Here is the mechanism, and the research behind every choice.

At a glance
How Sève stacks up.
The gel in your pocket is probably corn syrup, sea salt, and a preservative or two. Here are the same five questions asked of every gel on the shelf.

|---|---|---|---|---|---|
| Carb source | —100% maple syrup | Maltodextrin + fructose | Maple + maltodextrin | Maple + fruit concentrate | Rice, banana, maple |

Compared on publicly listed ingredients as of July 2026. Formulations change, check the current label. Brand names are property of their respective owners.
Get you to the finish, whatever's in the pouch. Maltodextrin, sea salt, a preservative to hold it on a shelf. It works for ninety minutes because almost anything does.
Over a 20-year career you'll take thousands of gels. Those choices compound, in your gut on hour four, and in your metabolic health for decades. Every line on our label is a bet you want to keep doing this at seventy.
Real maple, not maltodextrin.
Most gels are corn syrup. This is maple. Your gut knows the difference.
Maple carries two sugars in a natural ratio, so your gut opens two transporters at once and absorbs more fuel with less distress. Maltodextrin is a corn-starch polymer built for cost.
Maple's natural ~1:1 glucose-fructose ratio uses SGLT1 and GLUT5 together, delivering more carbohydrate per hour with less GI stress.
PubMed 20574242 →Maple carries 60+ identified polyphenols with antioxidant activity, a slower, more even glucose release than refined sugar.
PubMed 21795773 →Single-origin Canadian maple is a recognizable carbohydrate. Maltodextrin is a corn-starch glucose polymer built for cost and shelf-life.
Citrate over chloride.
Salt pulls water into your gut. Citrate doesn't. That's the cramp.
We use sodium and potassium citrate, not sea salt. It matters for performance today and for cardiovascular and bone health over the next thirty years.
Citrate metabolizes to bicarbonate, helping hold blood pH during sustained effort. Chloride doesn't buffer.
PubMed 14665584 →Sodium and potassium citrate deliver both electrolytes your body needs. Sea salt gives you sodium only.
PubMed 29324186 →Habitual high-salt intake is one of the most studied risk factors for stroke and cardiovascular events. Citrate is gentler across decades.
PubMed 19934192 →Magnesium malate, for mitochondria.
Most brands use the cheap magnesium. We use the one that works.
Recover uses magnesium malate, bound to a Krebs-cycle intermediate that feeds cellular respiration directly. Better absorbed, better tolerated.
Magnesium is required for 300+ reactions including ATP synthesis. Cellular ATP exists almost entirely as Mg-ATP.
PubMed 26166051 →Cheap magnesium oxide is poorly absorbed with a laxative effect. Malate enters cellular respiration directly.
PubMed 28218466 →Magnesium supports muscle relaxation and helps prevent cramping. Cumulative across a season.
PubMed 31624951 →70mg, calibrated on purpose.
Enough caffeine to help. Not enough to wreck your sleep or your gut.
Focus carries 70mg of natural caffeine from green coffee bean extract, about half a cup of coffee. The effective dose, not the loud one.
Caffeine blocks adenosine receptors, cutting perceived effort at the same pace, well below the jitter threshold.
PubMed 33388079 →Helps you push harder when it counts, especially the second half of long efforts.
PubMed 29876876 →Moderate, repeated caffeine intake is associated with reduced age-related cognitive decline in long-term cohort studies.
PubMed 20182054 →The mechanism, not a marketing curve
"Two sugars, two transporters. Up to 90g of carbs absorbed per hour, not a 60g ceiling."
Glucose travels through a single intestinal gate (SGLT1), which saturates at roughly 60g of carbohydrate per hour no matter how much more you eat. The rest sits in your gut unabsorbed. Maple's natural glucose-fructose mix opens a second gate (GLUT5), raising the ceiling to roughly 90g per hour in published exercise research. That's the real, measured difference. Not a dramatized blood-glucose spike-and-crash.
Illustrative curve shape based on published dose-response oxidation research (PubMed 20574242), not a head-to-head lab test of Sève specifically.
