Clean Lean Protein - a technical summary

Clean Lean Protein - a technical summary
Diet & Nutrition Education

Clean Lean Protein contains all essential amino acids.

It provides essential amino acids in the amounts recommended by the World Health Organisation.

The amino acid composition of Clean Lean Protein compares favourably with the recommended pattern of the Institute of Medicine of the National Institutes of Health

It contains up to 90% protein, making it one of the highest sources of protein available.

Clean Lean Protein provides an effective, complete solution for your protein requirements.

At a Glance:

Complete proteins contain all of the nine ‘essential amino acids‘ (EAAs) that the human body can‘t produce. Vegetarian sources have often been considered incomplete due to lacking one or more of these amino acids. Clean Lean Protein is an extremely high protein (up to 90%) supplement isolated from European Golden Peas. It provides a complete protein, with all EAAs in amounts comparable to or greater than dietary guidelines for health.

Full Article:

Amino acids that make up the proteins in our diet provide the ‘building blocks‘ for the creation and maintenance of all cells and tissue.

Of the 20 amino acids that the human body uses to create protein structures, nine need to be provided from the diet as they can‘t be synthesised within the body.

These nine Essential Amino Acids (EAAs) are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Two of these: methionine and phenylalanine, are closely correlated with ‘conditionally essential‘ amino acids (cysteine and tyrosine respectively) and so are often grouped together with these when discussing functional requirements.

It is commonly considered that the vegetable proteins are ‘incomplete‘, or in other words that they don‘t provide all essential amino acids (in contrast to the animal derived proteins that are considered to be complete). This is not factually correct though as some quality proteins such as high-quality pea protein isolates contain all essential amino acids, and in greater than, or near-equivalent amounts to those recommended by the World Health Organisation (WHO) for growth and development of the human body. In a functional sense the concept of ‘complete proteins‘ may also be flawed as it is not necessary to consume all amino acids required for human metabolism in one sitting.

Clean Lean Protein, a high-quality, premium golden pea protein isolate is a 100% vegan protein that contains all the essential amino acids.

The World Health Organisation (WHO) compiles evidence from all available scientific sources to determine the necessary amounts of nutrients for health. According to this information amino acids should be present in the following quantities per gram of protein:

WHO recommended mg/g protein Clean Lean Protein mg/g protein
Leucine 59 84
Isoleucine 30 45
Valine 32 50
Tryptophan 7 10
Methionine + cysteine 22 21
Methionine 16 11
Cysteine 6 10
Histidine 15 25
Lysine 45 72
Threonine 27 30
Phenylalanine + tyrosine 47 93

(WHO, 2007)

One can see that Clean Lean Protein exceeds all amino acid requirements for the healthy functioning of the human body as defined by the WHO except for a methionine and cysteine in which it is only fractionally under the recommended amount (by 1g in total). This amino acid profile also compares very favourably with the recommended amino acid pattern proposed by the Institute of Medicine of the United States National Institutes of Health (Dietary Reference Intakes for Energy, Carbohydrate, Fiber, Fat, Fatty Acids, Cholesterol, Protein, and Amino Acids (Macronutrients), 2005).

Just one serve per day of Clean Lean Protein helps to provide around ¾ of someones base amino acid requirements for health:

Amino Acids per Serve of Clean Lean Protein Amino Acids Recommeded per day (average) by the WHO Percentage of daily amino requirement for an average person in ONE serve of CLP
Leucine 1680 2418 69.48%
Isoleucine 900 1240 72.58%
Valine 1000 1612 62.03%
Tryptophan 200 248 80.65%
Methionine + cysteine 420 930 45.16%
Histidine 500 620 80.65%
Lysine 1440 1860 77.42%
Threonine 600 930 64.52%
Phenylalanine + tyrosine 1860 1550 120.00%

The concept of consuming protein with the recommended ratios of amino acids in every meal has been a concern for vegetarians and vegans in particular, however it is now considered unnecessary to combine protein types in order to provide all essential amino acids at all meals as a mixed diet (including one based solely on plant foods) can supply all necessary amino acids and encourage optimal protein status (Craig & Mangels, 2009; Young & Pellett, 1994). Other indicators of protein quality (such as allergen potential), absorption and total protein content are probably more important when evaluating protein supplements.

In conclusion Clean Lean Protein provides a complete protein solution for your athletic and general health requirements.
