Ingredient Science
ION Hydro Charge — Pure Electrolytes. Nothing Added. Nothing Missing.
Zero caffeine. Zero compromise. The universal hydration formula for India's long days and long distances.
Hydro Charge is built on a single principle: replace exactly what your body loses and nothing that it does not need. No sugar to spike your blood glucose. No caffeine to mask fatigue. Just the electrolytes your cells need to stay functional, hydrated and sharp — whether you are eight hours into a shift or eight kilometres into a run.
| Ingredient | Dosage | Function | Evidence |
|---|---|---|---|
| Sodium | Listed on label | Primary extracellular electrolyte · drives fluid into cells · prevents hyponatremia · maintains blood pressure during physical work | The most critical electrolyte for hydration. Depletion measurably impairs both physical and cognitive performance within 60–90 minutes |
| Potassium | Listed on label | Intracellular electrolyte · works with sodium to maintain fluid balance · supports muscle contraction and nerve function | Sweating depletes potassium rapidly. Replacement reduces cramping risk and maintains neuromuscular function |
| Magnesium | Listed on label | Muscle relaxation · ATP production · reduces inflammation · critical for sleep quality (supports Sound Sleep synergy) | Up to 60% of Indian adults are estimated to be magnesium deficient.Supplementation measurably improves fatigue outcomes |
| Vitamin C | Listed on label | Antioxidant · reduces exercise-induced oxidative stress · supports immune function during physical exertion | Immune suppression during heavy training is well-documented. Vitamin C reduces this effect |
| B-Vitamins complex | Listed on label | Cellular energy metabolism ·reduces fatigue at the enzymatic level · supports neurological function | B-vitamin deficiency is common in India — particularly B12 and B6. Supplementation improves baseline energy measurably |
Ingredient Science
ION Super Bright — The Antioxidant Science.
Skin health, at its biological root, is a matter of oxidative stress management,
collagen maintenance and cellular hydration. Super Bright addresses all three in a single morning tablet.
| Ingredient | Dosage | Function | Evidence |
|---|---|---|---|
| Glutathione | Listed on label | Master antioxidant · neutralises free radicals · inhibits melanin synthesis (skin brightening) · supports liver detoxification | Oral bioavailability of glutathione is significantly enhanced in effervescent liquid form compared to capsule delivery |
| Hyaluronic Acid | Listed on label | Skin hydration — holds up to 1000× its weight in water · improves skin elasticity · reduces appearance of fine lines | HA supplementation shows measurable improvements in skin hydration within 4–8 weeks in clinical studies |
| Vitamin C | Listed on label | Collagen synthesis cofactor ·antioxidant · skin brightening · enhances glutathione activity | Vitamin C is a required cofactor for collagen production — without adequate C, collagen synthesis is impaired |

| Biotin | Listed on label | Hair and nail strength · keratin production · metabolic health | Biotin deficiency is associated with hair loss and brittle nails — common in India due to dietary patterns |
Apple Cider Vinegar — The Metabolic Reset Science.
The metabolic and gut health benefits of Apple Cider Vinegar are well documented
but often undermined by the form in which it is consumed. Liquid ACV is highly acidic — damaging tooth enamel and stomach lining with regular use. Effervescent delivery provides the
same active compounds at a pH that your gut can handle.
| Ingredient | Dosage | Function | Evidence |
|---|---|---|---|
| Apple Cider Vinegar with Mother | Listed on label | Prebiotic properties · supports gut microbiome diversity · modulates post-meal blood glucose response · supports satiety | The 'mother' contains beneficial enzymes and bacteria. ACV has demonstrated blood glucose modulating effects in multiple controlled studies |
| Pomegranate Extract | Listed on label | Polyphenol antioxidant · anti-inflammatory · supports cardiovascular health · complements ACV's metabolic effect | Pomegranate polyphenols are among the most potent dietary antioxidants measured by ORAC score |
| Vitamin B6 | Listed on label | Supports protein and carbohydrate metabolism · reduces morning fatigue · supports immune function | B6 deficiency impairs metabolic enzyme function — common in high carbohydrate dietary patterns |
| Vitamin B12 | Listed on label | Cellular energy metabolism · neurological function · red blood cell production | B12 deficiency is endemic in India — particularly among vegetarian and vegan populations |
ION Sound Sleep — The Sleep Architecture Science.
Sleep is the period during which the body repairs, consolidates memory, clears
metabolic waste from the brain, and restores hormonal balance. Poor sleep architecture — fragmented REM cycles, delayed sleep onset, premature waking — undermines all of this.Sound Sleep targets three distinct points in the sleep architecture cascade.
| Ingredient | Dosage | Function | Evidence |
|---|---|---|---|
| Melatonin | Listed on label | Sleep onset signal — reinforces the natural melatonin rise without replacing it · reduces sleep onset latency · particularly effective in people with disrupted sleep cycles (shift workers, students, frequent travellers) | Melatonin is the most researched sleep supplement in clinical literature. Consistent evidence for reduced sleep onset time. Low dependency risk at therapeutic doses |
| Valerian Root Extract | Listed on label | Binds to GABA receptors (same pathway as benzodiazepines but without dependency risk) · reduces sleep onset anxiety · improves subjective sleep quality | Multiple meta-analyses show statistically significant improvement in sleep quality. Non-habit forming at supplemental doses |
| Passion Flower Extract | Listed on label | Synergistic GABA modulation with Valerian · sustains sleep depth through the night · reduces waking frequency | Studies show improved sleep continuity — the key factor for restorative deep-sleep stages |

Science FAQ
HOW DOES AN EFFERVESCENT TABLET ACTUALLY WORK?
Drop it in water. Citric acid and sodium bicarbonate react — producing CO₂ (the fizz) and releasing every ingredient into liquid suspension in under 60 seconds. By the time you drink it, every nutrient is already dissolved. Your body starts absorbing it almost immediately — no
capsule shell to break down, no stomach acid to survive first.
WHY IS EFFERVESCENT BETTER THAN CAPSULES OR PILLS?
Capsules must first dissolve in your stomach before absorption can begin — losing time and a significant percentage of the active dose to the acidic environment. Effervescent tablets are fully dissolved before you swallow them. Independent studies show 2 to 3 times better bioavailability in effervescent formats compared to equivalent capsule doses. You absorb more of what is on the label.
WHY DOES LEO ION NOT CAUSE ACIDITY OR STOMACH BURN?
Most supplements — and almost all energy drinks — are highly acidic. That acidity
irritates the stomach lining over time, particularly with daily use. Every Leo ION formula is pH-neutral by design. This is not a coincidence — it is why effervescent technology was originally developed for pharmaceutical drug delivery. Gentle on your gut. Even on an empty
stomach.
HOW IS GLUTATHIONE IN ION SUPER BRIGHT ABSORBED EFFECTIVELY?
Oral glutathione has historically had low bioavailability in capsule form — the digestive system breaks it down before it can be absorbed intact. Effervescent liquid delivery significantly improves this by presenting glutathione in a dissolved form that is absorbed through the small intestine more efficiently. The addition of Vitamin C in Super Bright further supports intracellular
glutathione production.
IS MELATONIN IN SOUND SLEEP HABIT-FORMING?
No — and here is why. Sound Sleep is calibrated to work with your body's existing
melatonin production, not replace it. The dose is set to reinforce the natural melatonin rise that begins around 9 PM, not to flood your system with exogenous melatonin. Long-term clinical use of melatonin at supplemental doses has not been shown to suppress natural melatonin synthesis or create dependency. This is a meaningful distinction from pharmaceutical sleep
aids.
WHAT DOES 'ZERO SUGAR' MEAN FOR ENERGY IN LEO ION?
Sugar creates energy via a glucose spike — which is always followed by an insulin-driven crash. Leo ION's energy comes from functional ingredients that do not cause this cycle: caffeine blocks adenosine receptors to reduce perceived fatigue, taurine supports neurotransmitter balance, and electrolytes maintain the cellular conditions for sustained physical and cognitive output. Energy without the spike. Without the crash.
WHY DOES HYDRO CHARGE PRO USE CAFFEINE AND TAURINE TOGETHER?
Caffeine alone inhibits adenosine receptors — reducing fatigue perception and improving focus. But caffeine in isolation can increase cardiovascular stress and anxiety at higher doses. Taurine modulates this: it balances neurotransmitter activity, reduces oxidative stress in neurons, and supports cardiovascular function during exertion. Multiple controlled studies confirm the caffeine-taurine combination produces significantly better performance outcomes than caffeine alone — and with a better side-effect profile.
WHEN IS THE BEST TIME TO TAKE HYDRO CHARGE PRO BEFORE A RACE OR TRAINING?
30 to 45 minutes before start time. This aligns with the absorption and peak plasma
concentration window for both caffeine and the electrolytes. Taking it too early (90+ minutes out) means caffeine peaks before your effort does. Taking it too late (under 15 minutes) means it has not fully absorbed when you need it. For long events over 4 hours, consider a second Hydro Charge (not PRO — no additional caffeine) at the midpoint for electrolyte top-up.
WHY IS HYDRO CHARGE THE POST-TRAINING FORMULA RATHER THAN HYDROCHARGE PRO?
After training, your goal is recovery — not stimulation. The caffeine in Hydro Charge
PRO, if taken post-training, would elevate cortisol (which is already high post-exercise), delay sleep onset and interfere with the muscle repair process that happens during rest. Hydro Charge provides the pure electrolyte replenishment your cells need without adding a stimulant at the wrong time. Same electrolyte matrix. No caffeine. That is the distinction.
IS LEO ION FSSAI APPROVED AND SAFE FOR DAILY COMPETITIVE USE?
Yes on both counts. All Leo ION products are FSSAI approved, GMP certified, ISO
certified and manufactured in an FDA-registered facility. For competitive athletes: Leo ION does not contain any WADA-prohibited substances. Caffeine was removed from the WADA prohibited list in 2004. All other ingredients in the range are freely permitted in competitive sport at the doses used. We recommend athletes verify with their specific sport governing body if in any doubt.
CAN I TAKE MULTIPLE LEO ION PRODUCTS IN ONE DAY SAFELY?
Yes — they are designed to be taken together across your day, with no ingredient
duplication that would cause over-supplementation. The only ingredient that appears in more than one product is Vitamin C (Super Bright and Hydro Charge) — at levels well within safe daily intake ranges. The total daily caffeine across Hydro Charge PRO is within safe limits for healthy adults. If you have a medical condition or are on medication, consult your doctor as you
would with any supplement.
