A whey protein isolate is a dietary supplement and food ingredient created by separating components from milk. Whey is a by-product of the cheese-making process. Whey can be processed to yield whey protein in three forms: whey isolate, whey concentrate, or whey hydrolysate. The difference between the whey protein forms is the composition of the product, particularly the protein content. Whey isolates contain the higher percentage of pure protein and can be pure enough to be virtually lactose free, carbohydrate free, fat free, and cholesterol free.

Uses
Whey protein is popular among athletes today because of its ability to be digested very rapidly and help return the post-workout body back from a catabolic (muscle-wasting) state to an anabolic (muscle-building) state. Whey protein isolates are also widely used in infant formula to provide a natural source of amino acids for optimal growth and development, as well as for protein fortification of bars, beverages, dairy products, extruded snacks and cereals and other food products.
Benefits
Whey protein is used for improving athletic performance, as a food supplement, as an alternative to milk for people with lactose intolerance, for replacing or supplementing milk-based infant formulas, and for reversing weight loss and increasing glutathione (GSH) in people with HIV disease.
Whey protein is also used for protein allergy, asthma, high cholesterol, obesity and weight loss, preventing allergies in infants, late-stage cancer, and colon cancer.
Cautions
Whey protein is LIKELY SAFE for most children and adults when taken by mouth appropriately. High doses can cause some side effects such as increased bowel movements, nausea, thirst, bloating, cramps, reduced appetite, tiredness (fatigue), and headache.
Special Precautions & Warnings:
Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking whey protein if you are pregnant or breast feeding. Stay on the safe side and avoid use.
Milk allergy: If you are allergic to cow’s milk, avoid using whey protein.
Interactions
- Levodopa interacts with WHEY PROTEIN
Whey protein might decrease how much levodopa the body absorbs. By decreasing how much levodopa the body absorbs, whey protein might decrease the effectiveness of levodopa. Do not take whey protein and levodopa at the same time. - Alendronate (Fosamax) interacts with WHEY PROTEIN
Whey protein can decrease how much alendronate (Fosamax) the body absorbs. Taking whey protein and alendronate (Fosamax) at the same time can decrease the effectiveness of alendronate (Fosamax). Don’t take whey protein within two hours of taking alendronate (Fosamax). - Antibiotics (Quinolone antibiotics) interacts with WHEY PROTEIN
Whey protein might decrease how much antibiotic the body absorbs. Taking whey protein along with some antibiotics might decrease the effectiveness of some antibiotics. To avoid this interaction take whey protein supplements at least one hour after antibiotics.Some of these antibiotics that might interact with whey protein include ciprofloxacin (Cipro), enoxacin (Penetrex), norfloxacin (Chibroxin, Noroxin), sparfloxacin (Zagam), trovafloxacin (Trovan), and grepafloxacin (Raxar). - Antibiotics (Tetracycline antibiotics) interacts with WHEY PROTEIN
Whey protein contains calcium. The calcium in whey protein can attach to tetracyclines in the stomach. This decreases the amount of tetracyclines that can be absorbed. Taking calcium with tetracyclines might decrease the effectiveness of tetracyclines. To avoid this interaction take whey protein two hours before or four hours after taking tetracyclines.Some tetracyclines include demeclocycline (Declomycin), minocycline (Minocin), and tetracycline (Achromycin).
