THE SCIENCE

Rethinking how
your body absorbs.

ZELYTE delivers electrolytes and caffeine through the buccal mucosa — the tissue lining your gums — for a direct absorption pathway that doesn't require swallowing or waiting.

FASTER DELIVERY  ·  HANDS-FREE  ·  NO LIQUID REQUIRED
HOW BUCCAL ABSORPTION WORKS
01

Place

Tuck the pouch between your upper lip and gum. It rests against the buccal mucosa — the thin, highly vascularized membrane lining the inside of your mouth — without any chewing or swallowing.

02

Release

Moisture activates the pouch, slowly releasing electrolytes and caffeine over 20–40 minutes. Controlled, steady, and continuous — no burst delivery.

03

Absorb

Compounds pass through the mucosal lining into the capillary bed beneath, entering the bloodstream without passing through the digestive system. [1,2]

Sports Drinks & Supplements

  • ✗ Swallowed → stomach → small intestine
  • ✗ Absorption delayed by gastric emptying
  • ✗ Requires a container or bottle to carry
  • ✗ Interrupts activity every time you drink

WHY ELECTROLYTES MATTER

The minerals that keep
your body in balance.

Electrolytes are electrically charged minerals essential for fluid regulation, nerve signaling, and muscle contraction. During exercise they're lost through sweat — replenishing them supports your body's normal function. [3]

Na · Sodium

Sodium

The primary electrolyte lost in sweat. Sodium helps maintain fluid balance between cells and tissues, and supports normal nerve and muscle function during activity. [3]

K · Potassium

Potassium

Works alongside sodium to maintain the electrical gradients across cell membranes that allow muscles to contract normally. Potassium supports fluid regulation inside cells and normal muscle function. [4]

Mg · Magnesium

Magnesium

Involved in hundreds of enzymatic reactions, including those governing muscle contraction and relaxation. Magnesium supports normal muscle and nerve function and is a key mineral for sustained physical activity. [5]

CAFFEINE

50mg. Precision-dosed.

Each ZELYTE pouch contains 50mg caffeine anhydrous — a clinically studied dose that supports focus and endurance during training, competition, or the grind. Do not exceed 2 pouches per session (100mg total).

Caffeine is one of the most studied compounds in performance research. At 50mg per pouch, ZELYTE provides a moderate, controlled dose that supports focus and energy without the abrupt spike associated with high-dose stimulants. No taurine, no synephrine, no proprietary blends.

Caffeine anhydrous is the standardized form used across performance research — consistent in dose and absorption characteristics. [6]
