What pack sizes are available?

LES MILLS™ Good Protein comes in a 30 serve or 12 serve pouch. The 30 serve pouch is 1.05kg (2.3lb) for $69.00. The 12 serve pouch is 420g (0.92lb) for $35.

How many grams of protein are in each serving?

There is over 25g of pure protein in each serving. To be exact this is 26.3g per serving for the vanilla and 26.1g per serving for the chocolate. The difference is because we had to make a little more room for the delicious cocoa in our chocolate version.

How do I use LES MILLS™ Good Protein?

We suggest adding one rounded scoop of LES MILLS™ Good Protein to 300-350 ml (10-12 fl oz) of water. However you can mix it into anything you like! Water is great, but to add some more flavor you could try mixing with: milk, almond milk, coconut milk, bananas, berries, fruit, nuts, seeds or vegetables in a blender.

What if the consistency isn’t right?

Simply add more or less water to your protein mix achieve the thickness or consistency that you like.

What if I find LES MILLS™ Good Protein too sweet?

Taste varies hugely between people. What might be perfect for your friend, might taste too sweet to you! If you have made up LES MILLS™ Good Protein and find it is too sweet, don’t be afraid to adjust it to suit your tastes. Simply add another 50ml or 100ml of water to your shake.

What is a milk protein concentrate?

Milk protein concentrate is made from real skim milk. The skim milk is filtered, (to concentrate the milk proteins), and then evaporated. This means that you get the same protein as you would get from real milk, the same types, (both casein and whey), and in the same ratio (80% casein and 20% whey).

Will Les Mills release a Vegan protein option?

Les Mills is looking at a vegan protein source as a future option. Stay up to do date and subscribe to our Newsletter on the home page of this site.

How is milk protein concentrate different to whey concentrate or whey isolate?

The milk protein concentrate used in LES MILLS™ Good Protein originates from real milk, with the same proteins in the same ratios as complete milk. Whey concentrates and isolates are made up of only part of the protein that is found in milk. They are a by-product of industrial cheese making. When cheese is made, most of the protein that is in milk (the casein) sticks together and the whey is washed away, this is the ‘curds and whey’. This means you are only getting one type of milk protein in a whey product. A milk protein concentrate contains both casein and whey, just like the original milk.

What is the difference between a protein concentrate and a protein isolate?

Concentrates and isolates both go through filtering steps. The difference is that isolates go through further processing steps in order to get to a higher purity of protein. Isolates are generally 95% protein, concentrates 80% protein. The processing steps to get to the 95% protein purity involve heat and acid. This extra processing means more of the milk’s original compounds are washed away, including protective milk fats, minerals, and vitamins A & C. Protein concentrates contain higher levels of some original milk compounds than isolates.

What is the difference between casein and whey proteins?

All types of proteins are made up of amino acids. Whey protein is known for its fast uptake, this means a quick supply of amino acids to muscles for protein synthesis in our bodies. Whey protein is easily soluble in water. Casein is known as a slow protein, it clumps together in our stomach and provides a slower sustained release of amino acids for several hours. This property of slow release is also beneficial for muscle recovery, providing amino acids over a long period of time is a good thing. Casein isn’t as soluble in water as whey and can take a bit longer to mix properly. We suggest giving your Les Mills Good Protein drink a few minutes to hydrate properly to give it the optimum texture.

How should this be stored and what is the shelf life?

Dry powders like this can be stored at room temperature (70˚ F) or kept refrigerated. The most important thing is to keep it dry – either sealed in the original pouch or another airtight container. The shelf life is 12 months, but note this is a best before date not an expiry date.

How much protein do I need?

There is no single answer to this question. Everyone is different, it depends on your diet, your weight and your physical activity. In terms of muscle recovery alone, more than 25g of protein in one hit is enough to provide the amino acids you need for several hours. Many studies suggest, when you are trying to gain muscle, that overall 0.8 – 1g of protein per pound of body weight per day is optimum.

When should I have my protein?

Protein can be used as a source of energy, for muscle recovery, or to stay on track with good food choices during the day. Check out the protein article here to learn more about timing, amino acids and muscle recovery.

Why isn't my LES MILLS™ Good Protein smooth in texture?

Les Mills Good Protein contains the same types of proteins and in the same ratios as real milk. This means 80% casein and 20% whey - as nature intended.  Casein takes a bit longer than whey to hydrate in your water or milk, this same property means that casein can provide a longer lasting supply of amino acids for muscle recovery. So, if you mix up your protein but give it a couple of minutes to hydrate, it will be smoother in texture as the casein hydrates completely.

Can I have LES MILLS™ Good Protein if I am lactose intolerant?

Les Mills Good Protein is low in lactose. Generally, it can be tolerated by the average lactose sensitive person. However, people who are allergic or sensitive to lactose should consult their health practitioner.

Are there any allergens in LES MILLS™ Good Protein?

There are no other allergens apart from milk, but to be on the safe side we declare all the allergens that may be in the same manufacturing facility, even the tiniest amounts, where our protein is also made.

This is the statement which is on our packaging: Allergy Information: Contains milk. This product is manufactured in a plant that also processes egg, fish, crustacean shellfish, tree nuts, wheat, peanuts,and soy ingredients.

Where is the protein from in LES MILLS™ Good Protein?

Our protein is sourced from grass-fed cows in New Zealand. Although we would have loved to use a USA-sourced protein, it turns out there just isn’t enough supply of grass-fed milk protein products available.

Are the cows pasture-fed?


Is it made using pasteurized or raw milk?

The milk used is not raw. It has been pasteurized before it is filtered and evapourated.

What should I mix LES MILLS™ Good Protein with?

Anything you like really! Water is great, but to add some more flavor you could try mixing with: milk, almond milk, coconut milk, bananas, berries, fruit, nuts, seeds or vegetables in a blender.

Why did Les Mills make a protein?

Many of the commonly used sports nutrition products on the market today contain sugar, fructose, fillers such as maltodextrin, artificial sweeteners, and many unnecessary vitamins and additives. Part of the Les Mills nutrition philosophy ‘support when pushing your body’ is to bring you simple, functional sport nutrition products. This means only the right stuff and no unnecessary ingredients.

Is LES MILLS™ Good Protein a complete protein?

Yes. Milk protein concentrate (and in fact any animal protein source) contains the full spectrum of amino acids, it is a complete protein.

What is in a Natural Flavor?

A natural flavor (in this case, Vanilla or Chocolate) are made up of extracts, essences, oils that are derived from spices, fruits, vegetables or other plant material. The function in food is to enhance the flavor and taste rather than give nutrition, this means the flavor is present at low levels.

Does LES MILLS™ Good Protein contain phenylalanine?

Can I have LES MILLS™ Good Protein instead of a meal or a snack?

Les Mills recommends consuming Good Protein in addition to a balanced diet – not instead of. We don’t endorse diets or fads, and that includes meal replacements. But, we are realists. We recognise that sometimes you just aren’t going to have time in your day for that healthy chicken salad lunch. If you’re having a busy afternoon, a LES MILLS™ Good Protein shake to curb your hunger is a much better option than chocolate cake!

Where is LES MILLS™ Good Protein made?

LES MILLS™ Good Protein is blended in the USA with grass-fed sourced milk protein concentrates from New Zealand.

What is Stevia leaf extract?

Stevia is extracted from the leaves of the plant Stevia rebaudiana. In South America the stevia plant has been used for centuries for its sweetness and medicinal purposes. In its pure form stevia is 300 times sweeter than sugar. In place of sugar, fructose (or artificial sweetners such as aspartame of acesulfame K), we have used stevia to give a pleasant sweetness to Les Mills Good Protein without the calories or negative metabolic effect of sugars.

What if I’m sensitive to Stevia?

There is no perfect natural sugar-free sweetener out there. After looking at all the options we’ve decided stevia is the best choice for Les Mills. The downside of stevia is that some people are much more sensitive to its sweetness than others. Here are some things that will help if you are sensitive to stevia: Mixing with coconut milk or almond milk instead of water, using Good Protein as an addition to a smoothie with fruit and other foods.

What is Guar Gum?

Guar gum is milled from bean of the Guar plant or Cyamopsis tetragonoloba. It is a type of dietary fiber. In LES MILLS™ Good Protein it helps provide a smooth texture.

What safety measures are used in its manufacture?

Processing and safety measures are in accordance with the FDA’s GMP guidelines. 

Is LES MILLS™ Good Protein gluten-free?

Yes – but please refer to allergy information on the packaging.
