High 5 Energy Source 4:1 Energy Drink Sachet

Energy Source 4:1 is designed for use during endurance exercise and contains 4 parts carbohydrate to 1 part whey protein isolate. This ratio can provide endurance athletes with more energy than carbohydrate alone and that protein protects muscles from being broken down and used as fuel during endurance training and competition. EnergySource 4:1 contains High 5's High Electrolyte Anti Cramping formula , which is designed to maximise fluid uptake and minimise the onset of cramp.

Research from Glasgow University showed that riders using EnergySource 4:1 during the 8-day trans Alp MTB race were on average 10% faster than matched athletes using a leading sports drink containing just carbohydrates.

Further research from Maastricht University showed that compared to a carbohydrate only drink, consuming a protein and carbohydrate drink lowered that rate of protein breakdown during hard exercise by 26% and raised protein synthesis (muscle building) by 33%.

47g single serving sachet makes 500-750ml of energy drink.

Manufacturer's Description

EnergySource 4:1 is an all-in-one sports drink for use both DURING and AFTER exercise. It contains 4 parts carbohydrate to 1 part whey protein isolate and key electrolytes. 4:1 is the Pro’s choice for hard training and multi-day endurance events. Use 4:1 when you anticipate a big step up in training intensity or volume, such as a training camp.

The ingredients in 4:1 help sustain performance during extended exercise and help maintain hydration by enhancing the absorption of water. Whey Isolate is a high quality source of protein. Protein contributes to the maintenance and growth of muscle mass. This can result in stronger, more resilient muscle.

Press Reviews

First, let's look at the carb component of this 4:1 drink. The packaging displays another ratio -- this time 2:1 -- which refers to the proportion of glucose to fructose.

The thinking behind the 2:1 is this: Using glucose-only products as a source of carbohydrate, most cyclists (or any athlete) can absorb only a limited amount - usually around 50g to 60g per hour, depending on body mass and other factors. High5 say that fructose can deliver more carbohydrate to the muscles, in addition to that provided by the glucose. Put in the simplest layman's terms, the fructose goes in another way, bypassing the mechanism that usually limits carb intake to around 50/60g per hour. The end result: you can increase your carb intake by up to 50%, meaning up to 75g or even 90g per hour, according to High 5. And that means you can go faster, or further, or both. High5 brands this mix as 'super carbs'.

Second, let's look at the protein component of this 4:1 drink. Is it really needed in addition to the carb? It depends. Simply put, in races or other events of around two hours or less, you need only carbohydrate to keep going. Once you get nearer three hours, and definitely over four hours, you need a bit of protein because - again to put it in the simplest layman's terms - it helps the carb work better. Sports scientists generally agree that the protein won't necessarily make you go any faster, but it will help you go for longer - which is exactly what you need in a 100-mile sportive, or similar endurance event. High5 say the ideal proportion of carb to protein is 4:1 - hence this drink.

So that's the science, but does Energy Source 4:1 actually work? Yes. It definitely works for me. From a personal point of view, having used a lot of different carb-based energy products over the years, with and without the addition protein, I definitely find a bit of protein helps. There's no doubt I feel stronger towards the end of a long sportive if I'm taking on protein as well as carb in the final few hours. My usual tactic is to carry a sachet or two of 4:1 in my back pocket, fill up with water at the final feed station, bung in the power, get back on the bike, give it a few minutes to fully dissolve, then take a sip every 10 minutes or so until I reach the finish.

And it's not just me. A lot of top-level riders use carb-protein combinations towards the end of a day's racing, especially in the tours. And that's because their soigneurs know that protein is essential to help muscle repair and recovery, so riders are ready for the next day. The High5 website promotes this angle too, emphasising that 4:1 is not just for single-day events, but also for multi-day events and training sessions.

What's it like in your mouth? The taste is okay, with two flavour options: citrus and summer fruit. The texture, as you might expect, is thicker than most carb-only drinks, more like milk than juice. Presumably this is due to the whey (which gives the protein) as well as the maltodextrin and fructose (which give the carbohydrate).

In addition to the carb and protein, Energy Source 4:1 also contains what High5 calls 'unique high electrolyte anti-cramping formula'. This refers to the sodium and potassium in the list of ingredients, which are certainly among the key minerals lost via sweat during extended exercise, which can lead to cramps if not replaced.

Functional Sports Nutrition Magazine

Energy Source 4:1 is the world's leading all-in-one training and recovery drink. It contains 4 parts carbohydrate to 1 part whey protein isolate combined with key electrolytes. Designed for use during exercise as well as recovery, it has a light taste, it's exceptionally easy on the stomach and it provides fast fluid delivery. It has been proven in many of the toughest endurance events in both the heat and cold. Research shows that a carbohydrate/protein combination can reduce muscle damage during exercise and increase post exercise muscle synthesis when compared to a carbohydrate only drink.

Bike Radar

A 55g serving provides 39g of maltodextrin and 4.5g of fructose-based carbs to 11g of whey-based protein -so still gives a good level of carbs when compared to other energy products. The H.E.A.C (High Electrolyte Anti Cramp) formulation, which maximises fluid uptake and minimises cramp, really seems to work well and this is the first energy drink I've tried that hasn't induced stomach cramps.

The drink is easy to prepare, although it does have a tendency to separate when stationary for any length of time. This is nothing that a quick shake can't sort, otherwise the last few mouthfuls aren't the most enjoyable!

During high intensity exercise EnergySource 4:1 really comes into its own. The energy-giving effects are felt almost instantly, allowing you to work longer, harder and without the feeling of excess tiredness. It is also fresh tasting, encouraging frequent consumption and doesn't leave an unpleasant after-taste.
