Dietary proteins also provide an important source of nitrogen and energy (providing 4kcal per gram).

In recent years, some studies confirm the hypothesis that hydrolysates seem to generate a faster muscle recovery effect than intact proteins ( 81, 82). It seems to be related to an increase in the bioavailability of amino acids, especially BCAA and EAA, as they have a positive effect on MPS ( 83). This increase in the bioavailability of amino acids is due to the fact that since they are pre-digested, the release of amino acids in the intestine is greater. In addition, it seems that peptides, especially di- and tripeptides, can be absorbed through specific transporters, leading to an even greater increase in blood aminoacidemia ( 84). Apparently, this hyper aminoacidemia also seems to be related to a possible thermogenic effect, which could have beneficial effects in athletes to reduce their fat body mass. Although further research is needed to confirm all these effects ( 85, 86). Other beneficial effects of protein hydrolysates on sport performance could be related to the generation of bioactive peptides. Bioactive peptides are defined as amino acid sequences that are not active in the precursor protein structure but that can exert physiological functions in the organism after their release through in vivo (gastrointestinal digestion) or in vitro hydrolysis (chemical or enzymatic). Since bioactive peptides were discovered in 1979, different biological activities have been described as antioxidant, antimicrobial, opioid, immunomodulatory, anti-inflammatory, antihypertensive, antidiabetic or hypocholesterolemic, among others ( 87, 88). In this sense, some studies reported that certain bioactive peptides may exert a positive effect on muscle glucose uptake and glycogen restore by activating insulin-independent AMP-activated protein kinase signaling in skeletal muscle cells ( 89, 90). Moreover, endogenous insulin appears to exert a positive effect on MPS due to their vasodilator effect by stimulating endothelial nitric oxide production, and increasing skeletal muscle glucose uptake ( 91). On the other hand, insulin has a similar structure to insulin-like growth factor-1 (IGF-1). IGF-1 is a hormone capable of exerting an anabolic effect on skeletal muscle. Therefore, insulin may simulate this effect ( 92). Some bioactive peptides could also increase plasma concentrations of glucose-dependent insulinotropic polypeptide, which implies an enhancement of insulin release from pancreatic beta cells ( 93). In fact, the greater insulinotropic effect observed after consumption of protein hydrolysates compared to intact proteins could explain their increase in MPS rate ( 94).

In other words, they’re for everyone. Choosing the right one for you comes down to what it’s made from. With the exception of vegan protein powders, most are made from whey (a by-product of cheese production), which comes in three different forms.

They are regarded as one of the top plant-based supplement companies around and they have a reputation for creating quality products. Overall, we rate this product very highly and think it’s one of the best vegan protein powders on the market in the UK right now. However, it is known that excess protein consumed beyond physiological ‘need’ is used for energy and the excess nitrogen is lost in urine, due to increased levels of amino acid oxidation and ureagenesis, therefore, even in active people, very high protein intakes above normal requirements will not necessarily be converted to muscle.

Review Conclusion – Our Final Thoughts Since our High-Protein Bar contains hydrolysed collagen as well as milk protein, it is not suitable for vegetarians or vegans — for anyone following a plant-based lifestyle, we recommend our Vegan Protein Bar, which comes in a range of delicious flavours. In addition to the intake of nutrients derived from the normal diet, some sport disciplines require the consumption of supplements that contribute positively to improve sports performance. These supplements, known as ergogenic aids, are defined as substances used to improve endurance, total fitness level and sports performance ( 5). Some of them, as creatine, caffeine, bicarbonate, protein and amino acids, have been used for different purposes: to increase energy intake, to maintain strength, to recover muscular mass or to prevent nutritional deficiencies, among others ( 6– 9). Two of the most marketed supplements in sports nutrition are proteins and amino acids. In fact, 80% of sports nutrition sales come from protein-based products, mainly in bars and powder formats ( 10), although the development of functional protein beverages is playing an important role in recent years ( 11). On the other hand, the current demand for more environmentally friendly products has increased research into more sustainable alternative sources of protein ( 10).

Protein hydrolysates are a complex mixture of peptides, mainly di- and tripeptides, whose production is based on the cleavage of the structure of protein sources by thermal, acid, or enzymatic treatment. Their composition depends on several factors and can be defined by the degree of hydrolysis, which is the fraction of peptide bonds that have been cleaved in the native protein ( 79). It is generally accepted that protein hydrolysates containing mostly di- and tripeptides are absorbed faster than intact proteins ( 80). Protein is relatively ubiquitous in the food system so a diet which is deficient in protein is also likely to be deficient in other nutrients such as vitamins and minerals. In developing countries where access to a balanced dis challenging, protein-energy malnutrition can develop, which can lead to the conditions kwashiorkor (severe malnutrition characterised by oedema) or marasmus characterised by thinness. Protein deficiency in the body can occur in anyone at times of increased demand (such as infection or stress), increased losses (such as haemorrhage, burns or diarrhoea) or dysregulation in protein metabolism.

On average, protein provides 17% of dietary energy in the UK and is the second most abundant compound in the body, after water. A large proportion of the protein in the body is present within muscle (43% on average) with significant proportions being present in skin (15%) and blood (16%). The main types of protein in the body are collagen (connective tissue), haemoglobin (red blood cells), myosin and actin (muscle fibres). Hudson JL, Bergia RE 3rd, Campbell WW.

When protein is consumed it is metabolised into amino acids and the body contains a pool of amino acids which are used to synthesise any proteins which are needed. Proteins are constantly being built and degraded in a dynamic process known as protein turnover. Bandara SB, Towle KM, Monnot AD.

Whey comes from the translucent liquid part of milk while casein comes from the top solid portion of milk. Both contain all nine essential amino acids. Other animal-based protein powders are made with egg white protein.

I found the powder mixed well with milk or even yoghurt thanks to the fine consistency and I love that it comes in so many different flavours. The powder is low in fat and sugar, although it does use sucralose and acesulfane K to sweeten, which might make some flavours a little sweet for some. 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.”
