Rehidrat Sport – Review

rehidrat sport

At first I was not entirely sure how this differed from the original Rehidrat, the contents seemed very similar just in slightly different forms.   Johnson & Johnson (manufacturing company) responded quickly to my question and pointed out that it is the same product, only in a new and improved outfit.

Rehidrat Sport comes in sachets providing 14 g  pf powder, which the directions say should be mixed with 250 ml of water.

The nutritional analysis of Rehidrat Sport is:

Nutrient Per 250ml reconstituted drink
Energy 50 kcal
Carbohydrate 12.9 g
Sodium 287 mg
Potassium 196 mg

A single serving will give you a 5% sugar solution along with electrolytes (sodium and potassium). Ideally for an exercise drink we should be looking for something that will give you 6-8% solution so this is in the ball park but might be a bit a little low for maximal absorption.  The sodium is a little high, ideally for a drink of this size we should only be looking for 125-175 mg and this is double that.  Excess sodium is not really a good thing and we usually get enough from our diet and excess sodium can affect blood volume, blood pressure and may worsen dehydration.  While we do not lose much potassium through sweat there may be some benefit to rehydration goals with the inclusion of potassium and its effect on fluid retention by the kidneys.

I would recommend Rehidrat Sport as an appropriate option to be taken during ultra endurance events where sweat loss may be extreme of for exercise lasting up to an hour for very heavy sweaters.  During the longer exercise sessions one should incorporate other more concentrated sources of carbohydrates from other sports drinks, gels, fruits or sweets to meet carbohydrate requirements.  The post exercise use of Rehidrat Sport won’t really be economical or practical to use to achieve recovery recommendations and glycogen repletion but may be used in conjunction with other options.  Aim for at least 1 g/kg carbohydrate after exercise with 20 g of protein.  An 80 kg athlete would need 6 sachets so it would be more sensible to use this combined with other foods.

Interestingly an ingredient in the powder is sodium bicarbonate which has potential as a buffer and legal performance enhancer.  The dose however in 1 sachet would not reach the levels which have shown performance enhancement in trials but it is interesting nonetheless.

The flavours available are naartjie and lemon-lime.  I find them pleasant to drink, not too strong a flavour and they are not sickly sweet.  In a nutshell you can consider these for use before or during short duration exercise or in combination with other carbohydrate sources during ultra-endurance events.  It could also be a good one for the heavy sweaters out there. Due to the lower carbohydrate content Rehidrat Sport might be a good starting point for anyone who has never used sports drinks. This will reduce the risk of stomach issues (cramps etc) that one may experience with other drinks of higher carbohydrate concentrations.
