Give your daily routine a strong foundation of antioxidant and immune support with Isotonix Vitamin C. Each serving delivers 500 mg of vitamin C in a buffered, isotonic-ready powder designed to mix with water for a smooth, easy-to-drink citrus beverage. Because our bodies cannot make vitamin C and diet alone may fall short, a well-designed supplement can help fill important gaps. This formula combines vitamin C (ascorbic acid) with beta carotene (vitamin A precursor) and potassium bicarbonate to support immune health, cardiovascular function, normal neurological health and overall cellular protection from everyday oxidative stress. Unlike many tablets and capsules, Isotonix Vitamin C is formulated to be taken as an isotonic solution—just add the directed amount of water—making it a convenient option for people who prefer a drinkable supplement. Why it works Antioxidant protection: Vitamin C is a hardworking water-soluble antioxidant that helps protect cells from oxidative stress and supports healthy aging at the cellular level. Immune & cardiovascular support: Adequate vitamin C intake helps support immune function and normal cardiovascular health as part of a healthy diet and lifestyle. Nervous system & cognitive support: Vitamin C and beta carotene support normal brain and nervous system function, helping you perform at your best every day. Electrolyte support: Potassium contributes to normal muscle function and healthy heart rhythm regulation. Suggested Use Pour one small capful (3.3 g) of Isotonix Vitamin C powder into a cup. Add 2 fl oz (60 mL) of water per capful and stir until fully dissolved. Drink once daily, preferably on an empty stomach for isotonic use, or as directed by your healthcare provider. Do not exceed suggested use. Safety & Compliance Dietary supplement. Use only as directed. Keep out of reach of children. If you are pregnant, nursing, taking medication or have a medical condition, consult your healthcare professional before use.
