Key benefits
Supplies quad-blend electrolytes lost in sweat – sodium, potassium, magnesium and calcium – to continually rehydrate and revitalise
Delivers an additional 50mg of caffeine boost to sharpen focus and reduce perceived effort
Gentle on the stomach, pH-balanced with zero colourants or preservatives
SLT07 is the highest single-serving, quad-blend electrolyte tablet on the market with 1000mg of sodium, 100mg potassium, 25mg magnesium and 15mg calcium per tablet. If you need powerful hydration fast, look no further. During vigorous activity and in hot conditions, some of us sweat more and saltier than others. Styrkr's effervescent tablets are dual-dosage. Use a whole tablet if you sweat heavily or are exercising in hot conditions. If you don’t sweat a lot and the conditions are mild, just use half.
SLT07 rapidly replaces the electrolytes lost in sweat, meaning you can perform at your peak for longer.
Helping athletes meet their daily water consumption goals, effervescent tablets can be a useful tool for promoting overall health and wellness.
Bioavailability is the rate that something is absorbed into the bloodstream to elicit its effect on the target area of the body. Effervescent tablets have a high bioavailability and high absorption rates.
Effervescent tablets provide a convenient and versatile option for people who dislike or struggle to swallow tablets, as they can be used anywhere and only require water.
Designed to be used as a supplement to help restore electrolyte balance in the body after intense physical activity and dehydration.
