Let’s do a little math here: What do you get when you have a warehouse gym, subtract air conditioning, add summer temperatures and multiply by one of the most intense fitness regimens around? The answer is sweat. Sweating a lot.

More sweat means more lost electrolytes, and Liquid IV Hydration Multiplier says it can help replace what you lose through sweat. According to Liquid IV, one packet of Hydration Multiplier powder is equivalent to drinking three bottles of water because of something called Cellular Transport Technology — I shouldn’t doubt the claim, but take it with a grain of salt.

The formula for Liquid IV Hydration Multiplier is rooted in a medical therapy developed by the World Health Organization called oral rehydration salts.

The Hydration Multiplier is not a medical therapy, but since it is based so closely on a hydration solution used by major health agencies for decades, I am confident that it will fill even the sweatiest of CrossFitters.

According to Liquid IV, salt, sugar, potassium, vitamin C, many B vitamins and water, combine in the right amount to deliver nutrients into your bloodstream faster than water alone. This too gluten freeno milk, non-GMO and vegan.

Miss Shaha certified personal trainer and yoga teacher, recommends Ultima Replenisher as a sports drink for those who want to lose weight because it has no sugar and no calories.

“I come back to Ultima when there’s a long day of hot yoga instruction in a 100-plus degree room and personal training,” says Shah. “Electrolytes are essential for muscle function and keeping you performing at your best and (Ultima) gives you that without the calories.”

Ultima Replenisher contains no sugar or artificial sweeteners — it’s sweetened with stevia — and the first ingredient listed on the powder packets is magnesium citrate, which is a good sign that this product is of high quality. Magnesium is one of the electrolytes lost through sweat; the fact that it’s the first ingredient on the list means it’s the most prevalent ingredient in the Ultima Replenisher quantity.

Ultima powder also contains calcium, zinc, manganese, chloride, potassium, sodium and phosphorous — all essential nutrients that need to be replenished after a good sweat.

We’ve become super naturals here. No, not supernatural — great natural, like the most natural drink you can drink while exercising and at the same level of water.

It’s hard to find a natural sports drink because most are full of artificial sweeteners, colors and flavors. Even sports drinks without them are still made in factories or laboratories and contain minerals that may not be as bioavailable as found in natural products.

Shah recommends Harmless Harvest Coconut Water to those looking for a natural alternative. Although it is not clearly marketed as a sports drink, Non-Destructive Harvesting of Coconut Water there are ingredients you should look for in a sports drink: sugar, sodium, calcium, potassium, phosphorus and magnesium. The real ingredient in the bottle, however, is organic coconut water. Coconut contains all the minerals that do not need fortification.

“It has all the electrolytes your body needs without any artificial ingredients,” says Shah, who tries to stay away from processed foods and drinks as much as possible. “Not only is coconut water hydrating, it helps your muscles and reduces soreness, and coconut water is better than most energy drinks I’ve tried before.”
