HIGH5 Isotonic Hydration Drink 300g – Blackcurrant

Train hard. Hydrate smarter. HIGH5 Isotonic Hydration Drink is your go-to electrolyte drink mix for fast absorption and dependable fuel when the pace rises and the heat builds. Designed for runners, cyclists, triathletes and team-sport athletes, this clean-tasting isotonic hydration powder helps you stay on top of sweat losses and keep your legs turning over without the bloat or stickiness of standard sports drinks.

Why it works

When you sweat, you lose more than water—you lose the minerals that keep muscles firing and your head clear. Each serving of HIGH5 Isotonic Hydration provides approximately 240 mg sodium, 90 mg potassium, 25 mg magnesium, 70 mg chloride and 36 mg calcium to actively replace what you sweat out. The smart combo of sucrose + dextrose delivers fast-acting energy that’s easy on the stomach, helping you maintain momentum from first kilometre to final push.

Unique to this formula, postbiotics are included to support digestive comfort under effort—ideal when intensity climbs or conditions are hot. The result? A light, refreshing blackcurrant drink you’ll actually want to sip little and often, keeping hydration simple and performance consistent.

Built for big efforts

Endurance runs and rides, especially in warm or indoor conditions
HIIT, turbo and race days where rapid hydration matters
Football, rugby, hockey and gym sessions with repeated high-intensity efforts

What you’ll notice

Rapid rehydration: Isotonic profile supports quick fluid uptake—no heaviness or sloshing.
Energy that keeps up: Fast-release carbs help sustain pace, power and consistency.
Electrolyte balance: Replenishes key minerals to support muscle function and concentration.
Stomach-friendly: Postbiotics included to support gut comfort when training hard.
Great taste, easy mix: Light blackcurrant flavour that goes down smoothly, session after session.

Pro tips

Begin hydrated and sip steadily rather than waiting for thirst—especially in heat or indoor training.
Use throughout sustained or high-sweat workouts to help maintain performance.
Pair with gels or chews on very long days if you need additional carbohydrate.

Ideal alternate to High5 Tablets

Great value for money and purchased as an alternate to tablets. Tastes just as good, mixes and dissolves easily. Comes with measuring spoon and very easy to use.

Good quality hydration powder

Very nice hydration powder, easy to mix and lovely flavour, dissolves into the water easy enough, doesn't leave any lumps of gritty taste (as long as you give the bottle a good shake)

Perfect for workouts when you're sweating and need to put salts, sugars and vitamins back into your system, also works very well for when you're ill (as I've discovered) if you're sick and can't/don't want to eat this is a great way to, at least, keep your body hydrated.

Tastes like tropical juice though not too strong (which some may like, others not so much)

Gives you 41 servings (depending on how much water you use and how big your scoops are) which isn't too bad for £22 (works out to about 50p per drink)

Very happy with the purchase and if I ever need an isotonic/hydration drink, this will definitely be the go to choice

Marmite

Excellent, good value for money and just what I've needed in this hot weather.

Mixes really easily.

Not mad keen on the taste but then I don't like black current, having said that it's perfectly drinkable.

Not sure if this is genuine

Why did you choose this product over others?:

The effervescent tabs are great this is awful

There are literal chunks of salt in it tastes bike nothing like the tablets

Tasty

Tasty and dissolves easily

No colon. Use it to rehydrate.

When I have been very ill it is helpful to rehydrate and re-energise. I will keep a tub now for emergencies.

Superb

The HIGH5 Hydration Energy Drink Powder is a game-changer in the world of sports nutrition, offering an exceptional blend of isotonic electrolyte hydration and energy-boosting carbohydrates. This product has become a staple in my fitness routine, and for good reason.

One of the key features of this energy drink powder is its isotonic formula. It's perfectly balanced to ensure rapid hydration and absorption, which is crucial during intense workouts or endurance sports. The difference in my hydration levels was noticeable from the first use, helping me to maintain peak performance throughout my activities.

The 28 grams of carbohydrates per serving is another standout aspect. This provides a substantial energy boost without feeling heavy or causing stomach discomfort, which can be an issue with some energy drinks. The carbs are easily digestible, offering a quick and sustained energy release that is essential during long exercise sessions or competitions.

Taste and mixability are often overlooked in energy powders, but HIGH5 has nailed it with their formula. The flavors are refreshing and not overly sweet, making it easy to drink during workouts. It dissolves quickly and completely in water, leaving no gritty residue or clumps, which is a testament to its high-quality formulation.

I also appreciate the thought that has gone into the product's packaging and portion sizes. The individual sachets are convenient for on-the-go use, making it easy to carry and mix wherever I am – whether it's at the gym, on a bike ride, or during a hike.

Moreover, the inclusion of essential electrolytes like sodium, potassium, and magnesium is a major plus. These electrolytes replenish what is lost through sweat, helping to prevent cramps and fatigue. This comprehensive approach to hydration and energy replenishment makes HIGH5 an all-in-one solution for endurance athletes and fitness enthusiasts alike.
