ATP Science Performance Hydration — Serious Electrolyte Replacement in a Sachet

Performance Hydration is ATP Science's electrolyte recovery mix — a low-sugar, naturally flavoured sachet formula built around a genuinely high-dose sodium matrix with herbal co-factors that most electrolyte products skip entirely. One sachet per day in 500–1000ml of water: 1000mg sodium, 200mg potassium, 60mg calcium, 50mg magnesium, 200mg curcuminoids, 40mg Schisandra Berry Extract 25:1, glycine and zinc. No artificial colours, flavours or sweeteners. 37.5 single-serve sachets per pouch, HACCP and GMP certified, made in Brisbane. In stock now at EatMe Supplements.

Best Suited To

The 1000mg sodium dose makes this product specifically appropriate for people who sweat significantly — athletes in sustained training, CrossFitters, cyclists, runners, triathletes, team sport players and tradies or outdoor workers in the heat. One reviewer describes it eliminating post-work headaches for her tradie partner on high-output days. Another found it eliminated post-gym fatigue. At the 1000mg sodium level, it's not a gentle everyday sipping drink — it's a proper electrolyte replacement for people who need it.

For lower-intensity use or non-athletic populations, ATP Science recommend starting with half a serve in 1000ml of water — maximum one full serve per day.

Why 1000mg of Sodium?

Most electrolyte products add a token amount of sodium — enough to put it on the label, not enough to meaningfully replace what's lost through sweat. Research shows sweat sodium losses range from 460–1840mg per litre, depending on the individual and exercise intensity. For heavy sweaters, athletes in the heat, or anyone doing sustained high-intensity work, losing 1–2g of sodium per hour of exercise is common. Performance Hydration's 1000mg per serve makes it one of the few electrolyte products actually dosed for athletes who sweat hard — not for the general wellness market. Sodium is also the primary driver of cellular fluid uptake; without adequate sodium, water you drink stays in the gut rather than crossing into the bloodstream and tissues where it's needed.

What's In Every Sachet

• Sodium (1000mg) — the dominant electrolyte lost in sweat and the primary driver of fluid absorption and retention. At 1000mg per serve, this is a meaningful replacement dose for active people — not a token inclusion.
• Potassium (200mg) — supports normal muscle contraction and nerve function alongside sodium. Research puts sweat potassium losses at 160–320mg per litre.
• Calcium (60mg) — muscle contraction and bone density support. Lost in smaller amounts through sweat but cumulative over long sessions.
• Magnesium (50mg) — sweat losses of 4–15mg per litre; plays a role in muscle relaxation, recovery and hundreds of enzymatic processes. A consistent shortfall in athletes is well documented.
• Curcuminoids from Curcumin (200mg) — the active compounds in turmeric, studied extensively for their role in managing exercise-induced inflammation and oxidative stress. Research in physically active populations shows curcumin supplementation reduces markers of exercise-induced muscle damage. At 200mg, this is a meaningful dose.
• Schisandra Berry Extract 25:1 (40mg) — a highly concentrated (25:1) extract of an adaptogenic berry used for centuries in traditional medicine. Studied for its role in supporting cognitive and physical performance under stress, with antioxidant activity relevant to training recovery.
• Glycine — a conditionally essential amino acid that supports connective tissue, collagen synthesis, and has a mild calming effect on the nervous system — appropriate in a post-training context.
• Zinc (2mg) — an essential mineral involved in immune function, protein synthesis and recovery. Lost through sweat and exercise, particularly relevant for athletes.

The Sachet Format

Individual sachets make this format particularly practical: one sachet goes into a shaker or bottle, no measuring, no scooping. Multiple reviewers call out the portability — ideal for the gym bag, work site, travel, or anywhere that a tub isn't practical. The 37.5 sachet pouch gives over five weeks of daily use.

What’s Inside

Salt (Sodium Chloride), Magnesium Aspartate, Food Acid (Citric Acid), Potassium Chloride, Calcium Citrate, Curcumin, Natural Flavours, Glycine, Schisandra Berry Extract, Natural Sweeteners (Steviol Glycosides, Thaumatin), Zinc Gluconate.

No artificial colours, flavours or sweeteners. Keto and low-carb compatible (<1g carbs per serve). Produced in ATP Science's Australian HACCP and GMP certified Brisbane facility.

How to Take It

Mix 1 sachet into 500–1000ml of cold water. Shake well — product may settle, reshake as needed. Consume during or after training, throughout a heavy workday, or any time significant sweat loss has occurred. Maximum 1 sachet per day. For light activity or general wellness use, half a sachet in 1000ml is sufficient.
