Is Whey Protein Isolate Safe If You Are Lactose Intolerant?

With whey protein coming from milk, there can be an issue if you are lactose intolerant. However, most of the lactose is removed from the whey when it is refined into the isolate state. This means that the isolate is much more suitable for those who are lactose intolerant than whey protein.

If you are lactose intolerant it is best to buy a pure whey protein isolate product. These products will have a much lower concentration of lactose (typically around 1%) that will be unlikely to set off a reaction.

If you are severely lactose intolerant, you should consult your doctor before starting to take whey protein isolate.

Is Whey Protein Isolate Safe If You Are Pregnant?

If there are no lactose intolerance issues, it is safe for pregnant women. Whey protein is often used in baby formula. Although there shouldn’t be any issues, as with any significant change to your diet when pregnant, it is best to consult a doctor.
