OstroVit Isotonic Sticks, Grapefruit – 30 x 5g

OstroVit Isotonic Sticks in Grapefruit flavour are single-serve powder sachets designed to be mixed with water to create a refreshing isotonic drink. Each of the 30 sachets contains 5 g of powder and delivers a blend of electrolytes — magnesium, potassium, sodium, and chloride — alongside vitamins A, D, E, C, and a range of B vitamins, plus 1000 mg of glucose per serving.

The grapefruit flavour gives the finished drink a light, citrusy character that many athletes find more palatable than plain water during or after a session. Because the osmolality of the drink is matched to that of human body fluids, it is classed as a true isotonic preparation rather than a standard flavoured drink.

With one sachet equalling one serving, the format suits runners, cyclists, and team-sport players who want a pre-portioned, straightforward way to prepare an electrolyte drink without measuring. The 30-sachet pack from OstroVit — a brand known for transparent labelling and consistent manufacturing standards — makes it easy to keep a few sachets in a kit bag or locker.
