Whey protein is the protein contained in whey, the watery portion of milk that separates from the curds when making cheese.
Whey protein is commonly used for improving athletic performance and increasing strength.
How does it work?
Whey protein is a source of protein that might improve the nutrient content of the diet. Whey protein might also have effects on the immune system.

Side Effects & Safety
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.
Do not take this combination!
- 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.
Be cautious with this combination!
- 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.<br/><br/> 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.<br/><br/> Some tetracyclines include demeclocycline (Declomycin), minocycline (Minocin), and tetracycline (Achromycin).
