Each 35g serving contains 24g of protein, with 5g of BCAAs, including 2.2g of leucine. The mix of whey and casein means it can be used at any time, whether you need an instant hit of protein after a workout or a steady stream over the course of a night. A serving also only contains 2.5g of sugar and 4.4g of carbs in total, and the powder comes in five dramatically-named flavours, including Cookie Chaos and Strawberry Siege. Whey isolate is more refined, and therefore more expensive. “Whey isolate is refined in a process that will remove the fat and the lactose from the compound,” says Butcher. “That makes it one of the leanest options, meaning it usually comprises of upwards of 90% protein content.” Whey concentrate is the most common form and is often the cheapest, according to Rachel Butcher, head nutritionist at Natural Fitness Food. “It typically has low fat and cholesterol content but the protein levels can vary from 40 to 90% depending on the brand,” she says. “If your goal is to build muscle, a whey concentrate with a higher protein content is probably the best to go for.” To decide on the best protein powder for you, it helps to ask: what are protein powders for? Protein is a nutrient needed all over the body to help build, repair and maintain tissue. It is made up of chains of amino acids, nine of which are termed ‘essential’ since your body can’t make them itself.

As a whey concentrate, MyProtein’s Impact Whey offers good value for money and at 103 calories per serving, it may be useful for those adhering to a calorie deficit. Each serving contains over 2g of the branched-chain amino acid (BCAA) leucine, which plays a key role in muscle synthesis. Protein supplements are used by all sorts of performers and athletes from football, tennis and golf players to stage performers and dancers,” says Shane Collins, founder of Circuit Society gym and co-founder of NUA Health supplements. “But we all cause damage to our muscles every day just by walking around and lifting things, and certainly when we train. Protein helps repair that damage.” Protein powders may be convenient for building muscle but they’re only really necessary for vegans, who don’t eat enough protein or elite athletes who are training most days every week. Personal trainer Max Lowery wrote in a 2mealday blog post, “The average untrained person needs as little as 60-75g of protein and the average trained person who exercises three times a week needs 1.2g - 2g per kilo of bodyweight. You can easily get enough protein from eating real food - the western diet is protein dense.” I have taken this every day for over a week now with no ill side effects, no bloating, no primevil sludge errupting from my bowels. Just glorious anacondas.For allergens contained in product, see ingredients marked in bold. Produced in an environment that processes Milk, Egg, Soy, Wheat, Peanuts and Nuts. However these contain many more calories from fat and carbohydrate than they do from whey isolate and concentrate,” Thompson explains. “Whilst these may help to increase mass, it is most likely the increase will come from fat rather than muscle.” Boasting 26 essential vitamins and minerals, as well as branch-chain amino acids (BCAAs), healthy fats and a complete profile of the nine essential amino acids, Huel’s protein powder ensures you’re getting more than just muscle fuel.
