90-95% of dietary protein is absorbed in the small intestines. Due to this high demand, the small intestines are able to absorb and retain large amounts of amino acids (the building blocks of proteins and muscle tissue); releasing them as needed by the body.
Many physiological processes relating to activity, energy, recovery, muscle strength gains and fat loss are linked to and require amino acids. Amino acids are classified into two main groups known as essential and nonessential amino acids. The 9 essential amino acids (histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine) cannot be made by the body and as a result, they must come from food or supplement sources.
The content and balance of amino acids, and the ratio of essential to non-essential, helps determine the value of protein quality. However the ability to use these amino acids requires that they be digestible, absorbable and bioavailable. That means the amino acids must be delivered to the tissues when needed. However, this can be tricky since free form amino acids are poorly utilized (can cause poor absorption of other amino acids), up to 18% less than peptide bonded (link amino acid residues within proteins), and most are destroyed by stomach acid.
Protein drinks are absorbed more efficiently than protein consumed with fiber-containing foods since fiber slows down nutrient absorption making REGIMEN™ GPACS™ perfect for faster protein absorption post-workout, as identified to be optimal for muscle repair and recovery.
Daily protein needs depend on a persons overall health and activity level. Guidelines for protein intake have often been determined using a person's total body weight.
For athletes or highly active people who are currently attempting to lose body fat while preserving lean muscle mass, a daily intake of 1.0-2.2 gram/kilogram bodyweight (0.45-1.0 gram/pound bodyweight) is an example of a good starting target.
If looking to maintain your body composition, a daily target of 0.8 gram/kilogram bodyweight (0.36 gram/pound bodyweight) and upwards is an example of a good starting target.
Since there are multiple variables that determine the need and level of protein consumed associated with the benefits of protein supplements, the flexibility designed into the REGIMEN™ GPAC™ precision nutritional delivery system offers high-quality functional protein for men and women alike no matter your regimen, workout, or sport.
The protein digestibility–corrected amino acid score (PDCAAS) has been used by FAO/WHO (Food and Agriculture Organization of the United Nations and the World Health Organization) as the preferred method for the measurement of the protein value in human nutrition since 1989, however the adoption of the digestible indispensable amino acid score (DIAAS) is expected to be implemented within 1-3 years.
DIAAS determines amino acid digestibility, at the end of the small intestine, providing a more accurate measure of the amounts of amino acids absorbed by the body and the protein's contribution to human amino acid and nitrogen requirements. Using the DIAAS method, researchers will now be able to differentiate protein sources by their ability to supply amino acids for use by the body, where PDCAAS values are generally overestimated as to the amount of amino acids absorbed (crude protein digestibility determined over the total digestive tract).
Some protein supplements may claim to contain a high protein content, but since the small intestine does not absorb all amino acids equally, they are not providing the same contributions required to meet a human's nutritional needs.
With REGIMEN™ GPAC™ protein, each pouch contains a pre-portioned blend of high-quality whey protein isolate and whey protein concentrate which has proven to meet the high-quality standards no matter the method chosen to evaluate protein quality.
An evidence based nutritional approach may enhance your resistance training and facilitate your muscle growth leading to an overall increase in strength. The goal of emphasizing both nutrient mixture and the timing of nutrient intake is to slow the catabolic state and activate the natural muscle-building hormones to facilitate recovery from exercise, maximizing muscle growth (i.e. anabolic state).
When we work out intensely, muscle tissue is damaged and rebuilt on a microscopic level. This is what ultimately makes us stronger, leaner, fitter, and more muscular, but muscle repair requires fuel.
Repair and rebuilding occurs through a process called Protein Turnover (the destruction of old, damaged proteins, (protein breakdown) and the construction of new ones (protein synthesis).
Muscle protein synthesis is increased slightly (or unchanged) after resistance workouts, while protein breakdown increases dramatically. The relationship between these two parameters represents the metabolic basis for muscle growth. At this point, we're doing a lot more breaking-down than building-up.
Protein synthesis is stimulated and protein breakdown is suppressed when you consume the right type of nutrients after exercise.
REGIMEN™ GPAC™ protein pouches now offer the freedom to take your protein supplement with you anywhere, replacing those high sugar protein bars and expensive and heavy Ready-to-drink beverages making your protein immediately available after your workout.
Protein is not the only concern, however. During exercise sessions, stored carbohydrates can also be substantially depleted. Thus, during the post-workout period, we require protein and carbohydrates. If you don't provide adequate post exercise nutrition fast enough — even if you delay by only a couple of hours — you decrease muscle glycogen storage and protein synthesis.
After resistance exercise, protein turnover is in negative balance shifting the body into a Catabolic state when protein synthesis is slower than protein breakdown.
The general belief in sports nutrition has been that Endurance Performance Athletes (EPA) require carbohydrate intake while Strength/Power Performance Athletes (SPPA) require more protein intake. But this is not totally true. All athletes have an increased need for increased protein.
The REGIMEN™ GPAC™ protein pouch provides lean protein to minimize fat gain during an anabolic state of training.
Nitrogen balance is just as important during fat loss (energy deficit – catabolic state) as during muscle growth (anabolic state). To minimize muscle loss during an energy deficit, increasing protein intake >20% has been found to be suitable to maintain nitrogen balance and now very easy to achieve for anyone using the REGIMEN™ GPAC™ protein pouch.
According to research published in “The American Journal of Clinical Nutrition” in 2008, protein is a more satiating nutrient than either fat or carbohydrate. That means adding whey protein to your diet can make you feel fuller, encourage you to consume fewer total calories and even improve your metabolic activity.
A study published in 2008 in the journal “Nutrition & Metabolism” demonstrated that subjects who consumed a whey protein drink twice daily as part of a reduced-calorie diet lost more fat and retained more lean muscle mass over a 12-week period than subjects who went without the supplement. These same high protein diets have been found to preserve lean body mass when dieting in both obese people and athletes and has also been shown to improve overall body composition.
