Protein requirements increase as you age due to a decline in skeletal muscle. This decline can be worsened by poor diet or inactivity. Accordingly, it is important to consume sufficient high-quality protein (particularly rich in leucine) to maintain muscle mass and strength, which is vital for mobility and to reduce the risk of injury and falls.

Peas are a sustainable crop that use less water and less land to produce than other protein sources. They also put nitrogen back into the soil! In addition to this, our peas are transported by barge to reduce our carbon footprint. All water used during processing is recycled and any waste goes to animal feed and biofuel. Even our tubs are 100% recyclable.

rotein is essential for the recovery and repair of muscle and body tissue. Clean Lean Protein contains all 9 essential amino acids and is particularly high in glutamine – an amino acid that is essential for post-exercise recovery and the prevention of muscle loss as we age.

Clean Lean Protein has a 98% digestibility rating, making it gentle on your stomach. Free from lectins and low in phytates, Clean Lean Protein won’t cause the bloating and digestive upset commonly associated with other types of protein supplements.

Clean Lean Protein is allergen-free and great for the whole family. No gluten, dairy, soy, nuts or eggs. No fillers, additives or preservatives. No added sugar or artificial sweeteners. Just clean, lean, European Golden Pea Protein with delicious natural flavours.

How to Use


Frequently Asked Questions

Yes. Clean Lean Protein is certified gluten free so it is safe for coeliacs.

Yes, it is vegan. The peas used in Clean Lean Protein are a vegetable source and the natural flavourings are all plant derived, making Clean Lean Protein 100% vegetarian and vegan.

Our body requires finely controlled pH levels in the blood (as well as tissues and other fluids) in order to maintain optimal health. Modern diets and non-vegan protein sources may cause an increase in acidity in the blood, which then needs to be buffered by the body breaking down bone and muscle tissue to free up ‘basic’ (alkaline) compounds. Clean Lean Protein provides a high level of good quality protein, without contributing to acid overload in the body.

Yes. Clean Lean Protein is Paleo friendly. Our natural enzymatic isolation process effectively removes the phytic acid, lectins and trypsin inhibitors that are usually the problem with legumes on a Paleo or Primal diet. This leaves a highly digestible protein, free of the problems associated with legumes.

The Pea Protein Isolate used in Clean Lean Protein is Kosher certified and the manufacturer, which blends Clean Lean Protein, complies with Kosher practices. The finished product however does not have an official Kosher certification.

Clean Lean Protein does not contain detectable quantities of phytoestrogens. Phytoestrogens are particularly abundant in soy products (including proteins), flax, wild yam, etc. While there are very low levels in some legumes, the protein isolation process we use in our protein removes any significant amounts from the sustainably grown European golden peas (Pisum sativum), leaving highly purified naturally derived amino acids and very little else – not even lectins!

According to our health advisors Clean Lean Protein is safe during both pregnancy and breastfeeding and may help provide some of the additional protein requirement during this time. However, every individual is different and may have specific requirements or a need for special caution so we always advise women who are pregnant or breastfeeding to seek independent advice from their health practitioner before taking any nutritional supplements.

According to the World Health Organisation (WHO), the additional protein requirements to support 13.8g gestational weight gain are 1, 9 and 31 g/day in the first, second and third trimesters, respectively. However, every individual is different and may have specific requirements or a need for special caution so we always advise women who are pregnant or breastfeeding to seek independent advice from their health practitioner before taking any nutritional supplements.

Clean Lean Protein has a number of advantages over whey. Some being:

  • It is highly alkaline. This helps the body to avoid problems of excess acidity (such as the potential for increased muscle and bone tissue loss in order to ‘buffer’ the blood)
  • Clean Lean Protein is higher in BCAAs and glutamine than WPC
  • It is a truly vegetarian protein source. Most whey protein is not because it’s a by-product of cheese making, in which they use rennet – an animal product – to separate the whey from the curds that provide the base for cheese
  • It is more sustainable. Getting quality protein from vegetable sources requires less environmental resource than dairy farming…so it’s better for the planet too!

The general rule is that if you focus on quality of nutrition, the quantities of what you eat will be less important. Stick to a diet that is almost entirely (80%+) natural, whole, unprocessed foods and you really can’t go wrong. Recognising that everyone is different, we never suggest a “one size fits all” diet. Please check out some of the nutritional articles on this site for more guidance, or contact one of our recommended practitioners.

Whole eggs are a great source of protein. While Clean Lean Protein is not necessarily “better”, it does offer some specific benefits. One whole egg contains around 6g of protein. The protein is highly bioavailable and has a PDCAAS (protein digestibility amino acid score) of approximately 0.9+. Our Clean Lean Protein has a PDCAAS of around 0.98 (slightly higher than whole eggs) but offers the advantages of being both highly alkaline and an isolated protein, meaning straight protein without other potentially negative factors (such as fat or sugar content). Eggs are also a relatively common allergen so Clean Lean Protein offers a quality protein option for those with allergies.

The fruit protein in Clean Lean Protein is derived from a West African plant called the Katemfe Fruit (African Serendipity Berry). The protein is known as Thaumatin. Thaumatin is a protein but classified as a natural sweetener. It is digested in your body just like any other protein.

Add 2 scoops or 1 single-serve sachet to a shaker containing 300ml or more of liquid and shake to mix. Can be mixed with your choice of water, milk, dairy-free milk or coconut water. Alternatively you can blend it with yogurt and berries into a delicious smoothie. See our recipes section for ideas.

Protein is the base of any healthy meal. Take Clean Lean Protein during the day as a snack, or post workout to aid your body’s recovery. Many of our customers use Clean Lean Protein in the morning (along with Good Green Vitality), after training (protein is critical for recovery from exercise) and in the mid-morning or mid-afternoon when the tendency can be to have a poorer quality snack.

This depends on the length of your workout, what your workout consisted of, and your physical size; along with your dietary structure and goals. As a rough ‘rule of thumb’ around ½ gram of protein per kilogram of bodyweight consumed within 30mins will help encourage recovery and repair of muscle tissue.

Our peas are grown in France and under strict conditions, and covered to reduce the risk of environmental damage and contamination. Unfortunately, due to local regulations, this means they cannot be certified organic. You can rest assured though that the product is pesticide, herbicide and GMO free. The only ‘certified organic’ pea proteins available at this time are of uncertain quality and so for the time being we consider Clean Lean Protein to be ‘better than organic’.

Phenylalanine is actually an essential amino acid and a component of every complete protein source. You may be thinking of the artificial sweetener Aspartame. Aspartame is created from phenylalanine and aspartic acid. Phenylalanine and aspartame are quite different compounds. For the record: we do not use aspartame to sweeten our products.

We only use the highest grade of European grown and processed Golden Pea Protein Isolate. There are cheaper pea proteins out there but they do not always have the same protein content and do not always guarantee a chemical free isolation process. Our patented, water-based isolation process also removes the phytic acid, trypsin inhibitors and lectins that can reduce the body’s ability to absorb minerals and protein, and that can cause intestinal distress. Cheaper proteins cannot guarantee the same quality and so you may not be getting your money’s worth – even at a lower cost.

Our protein is isolated using patented water-based enzyme technology. The process is completely natural and no solvents or hexane are used. The company from which we source the protein is called Cosucra and they are world leaders in their field. You can find out more about Cosucra and their protein product called Pisane on
