We understand your concern about product safety and quality. The Royal Green 100% Whey Protein Isolate, like all our products, undergoes rigorous testing to ensure its safety and quality. This includes testing for heavy metals to ensure it meets all safety standards.

However, the specific test results are usually not publicly available, as they are part of the manufacturer's confidential business information.

As for long-term consumption, whey protein isolate is generally considered safe for most people when used appropriately. 

I hope this answers your question! If you have more questions, don't hesitate to ask via email.

Yes, you can use whey protein during pregnancy.

Protein shakes are not directly intended for weight loss but are meant to support your protein intake when you are, for instance, on a diet or exercising a lot. The shake that does assist in weight loss is the Slim & Fit protein shake:

This shake contains fibres that, in combination with a calorie-restricted diet (and indeed plenty of exercise), help with weight loss.

Royal Green 100% Whey Protein Isolate consists almost entirely of whey proteins, with possibly traces of casein. Whey proteins are classified as fast-absorbing proteins. Casein, on the other hand, is absorbed more slowly, providing longer-lasting satiety and a gradual release of amino acids. A protein product that contains both whey proteins and casein is Slank en Fit:

It is not the case that the intake of whey protein isolate automatically affects the body fat percentage. The product description indicates that it can be used as part of a protein diet. It is such a diet (of which there are various types) that, in combination with the right form of exercise, can lead to a loss of body fat.

The mentioned usage advice of three shakes a day is particularly intended for the use of whey protein isolate for recovery and growth of muscle mass after intensive strength training.

For use within a protein diet, you can use this product as an ingredient in, for example, pancakes, bread, etc., to positively influence the ratio of carbohydrates to proteins. Mixing it into smoothies is also excellent. And you do not necessarily have to use 25 grams of powder three times a day every day. If on a particular day you already have plenty of protein from other sources on the menu, you can safely skip the use of Whey Protein Isolate for that day (though it is advisable to consume an opened package within about two months).
