DO I NEED TO CONSUME WHEY PROTEIN AT A SPECIFIC TIME OF THE DAY?
For any average person, protein takes longer to digest. So, it is preferable to consume Whey protein in the morning. Given the rapid absorption of whey, it is an ideal choice for post-workout intake to make the most out of the synergistic effect of insulin-amino acids.

ARE SOME PROTEIN SOURCES BETTER THAN OTHERS?
The quality of protein varies with different drink supplements. High-quality, or “complete” protein sources include animal-based proteins such as meat, fish, poultry, eggs, milk, cheese, yogurt, and Whey protein. These foods supply all the essential amino acids that your body needs to build and maintain muscle and to function properly. Protein found in most plant foods, including legumes, seeds, nuts, vegetables, and grain products is considered “incomplete” protein because it lacks some of the essential amino acids needed daily.

CAN PEOPLE WHO ARE LACTOSE INTOLERANT CONSUME WHEY PROTEIN?
If you are lactose intolerant, or are sensitive to lactose- the natural sugar found in milk products, a better option for you would be Whey protein isolate which contains very little lactose. The amount of lactose in Whey protein concentrate is higher.

WHEY PROTEIN OR CASEIN - WHICH ONE IS BETTER?
It is a very often asked question. There seems to be a great controversy over which one is better. Here is some information that directly compares whey and casein. Casein protein constitutes 80% of milk protein. It is recognized for its excellent amino acid content, slow-digestion, and anti-catabolic effect. It should be used at meals (can be combined with other proteins) and at bedtime. It should not be used when trying to accelerate amino acid absorption.
Whereas, on the other hand, approximately 20% of the protein found in milk is Whey protein. Whey is the richest natural source of BCAAs (branch chain amino acids) and is usually the preferred choice for muscle building, weight loss and maintaining health. It increases protein synthesis, enhances immune function, antioxidant activity and fast absorption. It is excellent to consume Whey protein during the time of workout due to its fast absorption rate.
Athletes and bodybuilders usually combine the two, consuming whey for quick protein replenishment and banking on Casein for its slow and steady protein release, leading to muscle recovery while they are asleep.

DOES PROTEIN MAKE ME FAT?
According to a 2008 study published in "Nutrition and Metabolism", 20g of Whey protein per day helped obese participants lose an average of 6.1 percent of their total body fat mass over a 12-week period. The amino acids in protein may help keep your blood sugar levels stable. If your diet is too high in carbohydrates your blood sugar levels go through peaks and valleys. You go from a burst of energy and feeling full to a lull and being hungry. In addition, if you are dieting, getting 17 grams of protein from a protein shake that has only 90 calories is better than getting your protein from a big meal which may have hundreds of calories.

I AM A VEGETARIAN. SHOULD I CONSUME WHEY PROTEIN?
It is a very tough job to acquire all the essential proteins for a vegetarian. Proteins are most commonly found in red and white meats. Proteins are also found in fish meat but the strands of proteins differ from cow and chicken meat. Whey protein is a complete protein i.e. it contains all amino acids. So, for a vegetarian, Whey protein becomes essential as their protein intake is very limited.

CAN I TAKE WHEY PROTEIN IN COMBINATION WITH OTHER SUPPLEMENTS?
Yes, Whey protein can be stacked with a number of other supplements like creatine, glutamine, dextrose, casein and others. But if you are planning to stack other supplements with Whey protein, it is recommended to consult to a doctor or a certified trainer before doing so.

The word ‘whey‘refers to milk serum which is the liquid by-product produced during the curdling of milk.
Whey protein contains 20% of the proteins that are present in animal milk. The other 80% is made up of casein. Whey protein is a mixture of globular proteins that have been isolated from the milk serum during production.

Whey protein contains all 9 essential amino acids. Among these amino acids, the BCAAs (Leucine, Isoleucine and Valine) are present in high quantities. The BCAAs account for 35% of the essential amino acids present in the muscle protein and 40% of the preformed amino acids required by mammals. All these combined give Whey protein the highest biological value than any known protein supplement.

TYPES OF WHEY PROTEIN
Whey protein is of three types:

• Concentrate (WPC): This is produced via ultrafiltration of whey or milk serum. This type of Whey protein is usually 80% protein. The rest of the product consists of lactose (4-8%), fat, minerals, and moisture.
• Isolates (WPI): Produced by a variety of membrane filtration techniques with the goal of reaching more than 90% protein concentration and the removal of most lactose constituents, this type of Whey protein is a good protein source for individuals with lactose intolerance as it is devoid of fat and contains little or no lactose.
• Hydrolysate (WPH): This type of Whey protein is produced via enzymatic hydrolysis of either WPCs or WPIs. Essentially, this acts as a method of 'pre-digesting‘the protein by separating peptide bonds; hence the time for digestion and absorption of amino acids will be reduced. Highly-hydrolyzed whey may be less allergenic than other forms of whey.

TYPES OF WHEY PROTEIN AND ITS USES:

PRODUCTION
When milk is treated to cause a shift in its pH value, the casein coagulates and separates. The raw whey is left uncurdled on top of the casein. It is then collected and subjected to a list of different processing steps which determine the quality and type of the Whey protein. During filtration, low molecular weight compounds like lactose, minerals and vitamins are removed to make the protein more concentrated. After filtration, the protein is pasteurized, evaporated, and then dried. The drying is done at low temperature to avoid denaturing.

The two most basic methods used to process Whey protein are:

• Microfiltration / Ultrafiltration
• Ion-exchange

HOW DOES IT WORK AND WHAT ARE THE BENEFITS
Proteins are essential macromolecules and perform a vast array of functions within all living organisms, such as metabolic reactions, replicating DNA, responding to stimuli, transporting molecules from one location to another, energy production, cardiovascular function, immune system functions and several others. Proteins differ from one another primarily in their sequence of amino acids. Proteins can thus be thought of as the building blocks of muscle tissue since muscles serve as the richest reservoirs of amino acids in the human body. Whey protein is a complete protein that contains all 9 essential amino acids that help in keeping your body fit.

SPORTS NUTRITION
Whey proteins are naturally-occurring dairy protein fractions that promote strong immunity, efficient muscle recovery and extend the overall benefits of physical activity. Whey proteins provide a number of unique benefits to athletes such as:

YOUR CONDITION AND SAFETY
Choosing the right Whey protein supplement will come down to a few factors that include budget, quality, flavor, lactose tolerability and intended uses.

Lactose Intolerance: If you are allergic or hypersensitive to milk, milk products or are lactose intolerant, then you should go for Whey protein Isolate which is devoid of lactose. Whey protein is bland in flavor, making it easy to incorporate into many recipes and food products.

Weight Loss: If you are looking to lose weight while maintaining a lean muscle structure, then you should opt for Whey protein isolates.

Vegetarians: Acquiring enough protein is often considered one of the hardest parts of maintaining a healthy vegetarian diet. Proteins are most commonly found in red and white meat. Fish also contains proteins, but the strands of proteins differ from those found in a cow or a chicken. For vegetarians, Whey protein become essential as their protein intake is limited to vegetables only.

Others: Body builders, beginners at the gym, marathon trainers, athletes etc., they all need Whey protein.

HOW MUCH
There is no universal answer to this particular question since everybody's protein needs vary. Protein requirements vary depending on an individual's age, gender, weight, medical conditions and the nature of the workout one does. The first thing to do is to determine your caloric and macronutrient allotments. After calculating the BMR (Basal Metabolic Rate) and applying the Harris-Benedict Principle, one could know how many calories are needed on a daily basis.

Step 1- Calculating BMR:

Step 2- Applying the Harris-Benedict Principle :
The following table enables the calculation of an individual's recommended daily calorie intake to maintain optimum weight.

WHEN
The best results can be seen when Whey protein is consumed in the morning, after a workout. If you exercise regularly, it may be best to consume a Whey protein shake immediately following a workout. A report published by the National Strength and Conditioning Association recommends consuming at least 15g of protein after each workout.
Your body is highly sensitive to insulin after exercise and shuttles carbohydrates and proteins into muscle cells instead of fat cells. This sensitivity declines post-workout until ~2 hours at which point it reaches baseline.
Furthermore, the anabolic effects of insulin are synergistic with amino acids. Given the rapid absorption of whey, it is an ideal choice for post-workout to take advantage of the insulin-amino acid synergistic effect.

STORAGE
Storage of the Whey protein under cool and dry place is highly recommended. Whey protein can be denatured by heat or high temperature. Heat-denatured whey can still cause allergies in some people.

ALLERGIES
No matter which Whey protein you choose, make sure to read the label carefully. It’s also important to talk to your doctor before starting any new supplement or diet program.
With many additional ingredients in all the three Whey proteins, it’s essential to know what your body is able to process or if you have any allergies to certain foods.

• BSA (bovine serum albumin) is thought to be a possible trigger for IDDM. Some studies have found increased levels of anti-BSA antibodies in sera from children developing IDDM. However, other studies have shown no increases in anti-BSA in IDDM children. Thus the exact role of BSA in IDDM development remains unclear.
• Kidney damage. Research does not support the idea of kidney damage.  However, some researchers warn against excessive protein intake (>2g/kg of body weight per day).
• Increased risk of dehydration with excess intake of Whey protein.
• Possible risk of calcium loss. Very large amounts of protein intake results in increased acid production. Calcium is released from bone as a buffer for the increased acid load.
• These side effects can generally be easily alleviated by monitoring your total protein intake and making sure you are aware of any possible food allergies that you may have. If a nominal dose of Whey protein consistently causes stomach or gastro intestinal issues, consider trying a different Whey protein supplement or adding in a digestive enzyme to take along with it.
