New Longevity Benefits of Whey Protein
Anabolic whey protein is often taken by athletes shortly after their workouts. They found that as long as protein consumption over the period of the day met a sufficient level approximately 1. J Int Soc Sports Nutr First, whey represents a high-quality protein supplement for aging persons—with a rich source of BCAAs to stimulate protein synthesis and inhibit protein breakdown.
Choosing a Protein Shake
Casein The next most commonly consumed form of protein powder is micellar casein protein. Good Sources of Protein after a Workout. Another study examined net protein balance levels, and in particular net muscle protein elevation positive balance following a similar methodology Best Supplements for Protein Synthesis.

They concluded that, despite very high levels of insulin resistance in some of the individuals, whey was still able to decrease blood sugar levels.
In , scientists reviewed many previous studies and concluded that the evidence supports the use of whey as a therapeutic treatment for obesity. In a host of studies—all with similar conclusions—scientists have investigated pathways through which the proteins, peptides, and minerals in whey boost satiety, influence glucose homeostasis, and optimize lean body mass. The branched chain amino acids play an essential role in supporting lean muscle mass, especially among older adults.
After 16 weeks, the leucine group lost 6. This supplement should be taken in conjunction with a healthy diet and regular exercise program. Individual results are not guaranteed and results may vary.

What You Need to Know Whey: The New CR Powerhouse Although whey is often viewed simply as a protein source, emerging evidence indicates that the branched-chain amino acids BCAAs and other fractions found in whey act as a calorie restriction-mimetic.
Studies on middle-aged animals demonstrate that supplementing with the branched chain amino acids and other components in whey increase median life span by up to the equivalent of 9. A study from the November issue of the journal "Anticancer Research" found that whey protein caused levels of glutathione in tumor cells to decrease. According to the researchers, the lower levels of glutathione rendered these cells more vulnerable to chemotherapy.
However, you should not attempt to cure any medical condition with any supplement without speaking with your doctor. Insulin is an important hormone because it helps your body regulate blood sugar levels and how your body stores food as energy. Diabetes and obesity are conditions that are caused by irregularities in your body's use of insulin. Research indicates that whey protein may help prevent these conditions by improving your body's use of insulin.
A study from the April issue of the "British Journal of Nutrition" found that 12 weeks of whey protein supplementation improved insulin levels and also decreased insulin resistance scores. It's important to note that this research was performed in obese individuals only, so your experience may vary.
Video of the Day. This article aims to answer that question so you can know whether pre-sleep protein is an essential nutritional technique or just a waste of your supplements! We all know that in order to sustain or gain muscle, we have to ensure a balance of protein synthesis vs degradation is tipped towards positive Generally, protein balance will start to become or remain negative in the absence of nutrient intake such as when sleeping at night It is of course a reasonable assumption that the reduction in availability to amino acids will halt muscle protein synthesis rates and lead to degradation which no bodybuilder or gym bunny wants.
Protein powder supplements are a popular and very importantly, convenient method of boosting protein levels in a timely way 5. For the purposes of this article we will consider whey and casein protein as the two key options for pre-bed supplementation. Most modern whey proteins available are whey varieties, of which there is isolate, concentrate and hydrosylate.
Whey is considered the highest quality protein source due to its high concentration of branch-chained amino acids and fast acting response to promote muscle protein synthesis The issue with whey as a pre-fast protein source is that without physical exertion training whey will quickly be transferred to storage as fat 5. Obviously, unless you train just before you pull back your duvet cover and climb into bed, then it is likely that during the night some of the whey consumed will end up being stored or broken down and excreted.
This is obviously an inefficient use of your beloved protein powder. The next most commonly consumed form of protein powder is micellar casein protein. Now whilst whey protein is essentially a byproduct of the waste in the cheese production process, casein is the predominant form of protein in milk.
Casein protein is the curd portion of milk, which is produced as part of the cheese-making process. Just as whey is a high quality form of protein, so is casein due to its high levels of essential amino acids 7. However, the essential difference between casein and whey is the speed at which their amino acid load is released into the blood stream. Simply put, due to its insolubility in the stomach casein has a slower digestive time- meaning a release of its amino acids over a longer period As such this will result in a prolonged period of positive net protein balance.
The benefit of this is a reduction in the impact of muscle protein breakdown, particularly during periods of fasting Interestingly, most studies comparing casein to other forms of protein usually whey and soy usually conclude by extolling the favourable benefits of whey as the key protein for muscle protein synthesis as this is usually the main reason people will consume such supplements.
Such studies however will predominantly examine the immediate or short term response of protein consumption, and if measurements are extended over several hours, casein demonstrates a prolonged beneficial effect which other proteins do not Strictly speaking, the preferred choice of protein type is dependent upon your predominant objective. Of course post workout muscle protein synthesis is definitely greater following consumption of whey protein compared to casein However, theoretically casein may have its own benefits in a different way.
This is due to its different rate of absorption by our gut, and the impact this rate has on post prandial protein balance. One study 8 examined the effect of consuming both whey and casein protein as the protein source in a single meal.
They measured a number of physiological properties including protein balance and the use of leucine in the body. They noted a variable response to each of the protein types: Of course, when is protein breakdown the highest? When fasting such as overnight when asleep! The previous study mentioned outlines the theory behind why people choose to consume a source of protein usually casein before bed. However, does this theory hold water?
In order to discuss this we need to examine whether timing of protein consumption is likely to show benefit. It is well recognised that active people will have a greater demand for protein from their diet and supplements due to the elevated levels of protein oxidation and breakdown occurring during exercise , and to ameliorate the responses of muscle protein regeneration vs proteolysis breakdown during recovery They would consider it wise to strategically plan protein intake as an integral part of their training, recovery and nutrition regimes We should consider then, what evidence is there to support the theory that pre-bed protein consumption will give us added benefits?
It is evident that the reduction in available amino acids during periods of fasting, like over night during sleep, will prevent a rise in muscle protein synthesis Researchers have evaluated the impact of protein ingestion prior to subsequent overnight recovery on a number of variables including:.
Iamges: anabolic protein shake benefits
For example a 23 study meta-analysis of people 25 concluded that any beneficial changes to strength and hypertrophy relative to protein consumption where more attributable to total protein consumption, rather than when it was consumed. For eleven mornings, they gave 0 , 5 , or 30 grams of protein from whey protein concentrate and canola oil to all participants along with doses of 50 grams of oral glucose.
Strength was evaluated by 1 rep max testing. Protein shakes can range in their protein content, but all contain some carbohydrates and maybe a little fat. This supplement should be taken in conjunction with a healthy diet and regular exercise program.
Higher-protein diets improve indexes of sleep in energy-restricted overweight and obese adults: The team concluded that whey protein boosted metabolic rate in the test group and may be beneficial anabolic protein shake benefits preventing the development of type II diabetes. Health Benefits of Whey Protein Powder. Interestingly, most studies comparing casein to other forms of protein usually whey and soy usually conclude by extolling the anabollic benefits of whey as the key protein for muscle protein synthesis tren ace quad injection this is usually the main reason people will consume such supplements. This effect is modulated along typical CR pathways—boosting mitochondrial biogenesis, reactive oxygen species ROS anxbolic, cell anabolic protein shake benefits, and expression of sirtuin 1 SIRT1 —the mammalian longevity gene CR.
