- 𝗡𝗨𝗧𝗥𝗜𝗧𝗜𝗢𝗡𝗜𝗦𝗧 𝗙𝗢𝗥𝗠𝗨𝗟𝗔𝗧𝗘𝗗 – Unlike other electrolyte powders & tablets, our electrolytes are free from sucralose, colouring, artificial flavours, and added sugar. Each sachet is loaded with goodness — 1,000mg of Sodium, 300mg of Potassium, 70mg of Magnesium, 40mg of Vitamin C, 52mg of Calcium, 2.5mg of Zinc and absolutely Zero Sugar!
- 𝗡𝗢𝗧 𝗢𝗡𝗟𝗬 𝗙𝗢𝗥 𝗣𝗢𝗦𝗧-𝗪𝗢𝗥𝗞𝗢𝗨𝗧 – Dehydration can happen for various reasons, not only during a workout. Electrolytes are commonly included in hydration products, and staying hydrated can support overall wellness, whether before the gym, after a run, or as part of a daily routine.
