TENEL LABS

Formulated for the court. Perfected for every day.

TENEL™ provides 900 Mg Sodium and essential electrolytes in ratios that match the physiological demands of tennis performance.

Clean ingredients. Science-backed formulation. Zero sugar. Zero compromise—whether you're competing or just getting through your day.

How the Ingredients Work

900 Mg

Sodium

High-intensity lateral movement elevates sweat sodium loss, requiring approximately 70% replacement per hour to maintain plasma osmolality near 140 mmol·L⁻¹ and preserve stroke accuracy.

Standard sports drinks deliver only 300-400mg—creating a deficit that manifests as fatigue, mental fog, and diminished power in later games—which is why TENEL provides 900mg: replacement at the rate your body actually requires.

250 Mg

Potassium

Potassium replenishes intracellular stores depleted through sweat and works in direct opposition to sodium to maintain cellular fluid balance.

This optimal Na⁺:K⁺ ratio accelerates sodium-dependent glucose transport in the gut while regulating muscle contractions, supporting nerve signaling, and preventing the muscular fatigue that manifests as slower footwork and delayed reactions on court.

65 Mg

Magnesium

Magnesium supports ATP production—the energy currency that powers every muscle contraction—and facilitates neuromuscular relaxation between explosive efforts.

Adequate Mg²⁺ levels mean faster recovery between points, reduced muscle tension that preserves stroke mechanics, and sustained power output through repeated serves and volleys.

60 Mg

Calcium

Calcium ions trigger the actin-myosin cross-bridging that enables muscle contraction at the cellular level. Even subclinical Ca²⁺ depletion impairs force generation and is directly linked to late-match fatigue.

Adequate calcium maintains the fiber recruitment necessary for explosive serves, rapid directional changes, and sustained power output when matches extend into deciding games.
