2nd opinion

Dr. Rania Mousa General Medicine
Whey protein is likely safe for most adults when used in amounts recommended, taking the daily doses of whey proteinwithout exceeding 1.2 grams per kilogram of body weight.
It is possibly safe when taken by mouth as a single dose of up to 50 grams, or when 30 grams is taken by mouth daily for six months,note that this is different depending on brands .
Harm comes from long term use ,or overdosage.
>Try to read the label before using .
Side effects of whey protiens if taken randomly with no moderation:
-abnormal heart rhythms, changes in cholesterol levels, headache, increased diabetes risk, increased fracture or osteoporosis risk, kidney dysfunction, liver damage, stomach or intestine symptoms (acid reflux, bloating, constipation, cramps, gas, increased bowel movements, movement problems, nausea, reduced appetite, swelling of limbs, and upset stomach), and thirst.

Whey protein may lower blood sugar levels. Caution is advised in people with diabetes or low blood sugar, and in those taking drugs, herbs, or supplements that affect blood sugar. Blood sugar levels may need to be monitored by a qualified healthcare professional, including a pharmacist, and medication adjustments may be necessary.

Whey protein may increase the risk of bleeding. Caution is advised in people with bleeding disorders or in those taking drugs that may increase the risk of bleeding. Dosing adjustments may be necessary.

Whey protein may interfere with the way the body processes certain drugs
Whey protein may cause low blood pressure. Caution is advised in people with low blood pressure or in those taking drugs or herbs and supplements that lower blood pressure.

Drowsiness or sedation may occur. Use caution if driving or operating heavy machinery.

Use cautiously in people who take medications, including agents that affect the immune system and agents that lower cholesterol.

Use cautiously in people with stomach or intestine disorders.

Avoid in people with known allergy or sensitivity to milk or milk products, including cow's milk, sheep's milk, goat's milk, and mare's milk.

Avoid in people who are avoiding the use of dairy products.

Avoid using whey protein long-term and in excessive amounts.
My advice is that it is better to fulfill your protein intake from a balanced protein diet .
