Overview

Whey protein is the protein from whey, the watery portion of milk that separates from the curds when making cheese. It is commonly used as a protein supplement.

Whey protein might improve the nutrient content of the diet and also have effects on the immune system.

People commonly use whey protein for improving athletic performance and increasing strength. Whey protein is also used for asthma, diabetes, weight loss, and many other conditions, but there is no good scientific evidence to support most of these uses.

Uses & Effectiveness ?

Possibly Effective for

  • Athletic performance. Regularly consuming whey protein by mouth while also regularly exercising increases muscle strength and athletic performance. But it seems that both must be done consistently to see benefits.

Possibly Ineffective for

There is interest in using whey protein for a number of other purposes, but there isn't enough reliable information to say whether it might be helpful.

Side Effects

When taken by mouth: Whey protein is likely safe for most adults when taken appropriately. High doses can cause some side effects such as increased bowel movements, acne, nausea, thirst, bloating, reduced appetite, tiredness, and headache.

Special Precautions and Warnings

When taken by mouth: Whey protein is likely safe for most adults when taken appropriately. High doses can cause some side effects such as increased bowel movements, acne, nausea, thirst, bloating, reduced appetite, tiredness, and headache. Pregnancy and breast-feeding: There isn't enough reliable information to know if whey protein is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

Children: Whey protein is likely safe for children when used in amounts commonly found in food or when included in infant formulas.

Milk allergy: If you are allergic to cow's milk, avoid using whey protein.

Interactions ?

    Major Interaction

    Do not take this combination

  • Levodopa interacts with WHEY PROTEIN

    Whey protein might decrease how much levodopa the body absorbs. This might decrease the effects of levodopa. Do not take whey protein and levodopa at the same time.

    Moderate Interaction

    Be cautious with this combination

  • Antibiotics (Quinolone antibiotics) interacts with WHEY PROTEIN

    Whey protein might decrease how well some antibiotics work. To avoid this interaction, take antibiotics at least 2 hours before or 4-6 hours after whey protein.

  • Antibiotics (Tetracycline antibiotics) interacts with WHEY PROTEIN

    Whey protein might decrease how well some antibiotics work. To avoid this interaction, take antibiotics at least 2 hours before or 4-6 hours after whey protein.

  • Bisphosphonates interacts with WHEY PROTEIN

    Whey protein can decrease the effects of bisphosphates. To avoid this interaction, take bisphosphonates at least 30 minutes before whey or, preferably, at a different time of day.

Dosing

Whey protein has most often been used by adults in doses of up to 30 grams by mouth daily for up to 6 months. Speak with a healthcare provider to find out what dose might be best for a specific purpose.
