Supplement Sensitivities

When the body is sensitive to certain foods, there are some common symptoms to be aware of, which typically present themselves within a couple of hours. If you have symptoms on a daily basis, then start paying attention to what you regularly eat. For many, that is their workout shake.

Protein powders have become exceptionally popular especially for those that enjoy a work out! Whey protein is a popular fitness and dietary supplement. It’s made from whey, whey is the liquid remaining after milk has been curdled and strained. The whey is then filtered, refined and spray-dried into whey protein powder.

There are three main types of whey protein. The key difference between them is how they are processed:

  • Whey protein concentrate: Contains roughly 70–80% protein. It’s the most common type of whey protein and has more lactose, fat and minerals from milk.
  • Whey protein isolate: Contains 90% protein or more. It’s more refined and has less lactose and fat, but it also contains fewer beneficial minerals.
  • Whey protein hydrolysate: This form is pre-digested, allowing your body to absorb it faster.

If you have a Protein sensitivity you may display some or all of the below symptoms:

  • Neurological problems – like severe headaches and migraines
  • Skin issues – most commonly eczema, acne, itchiness and rashes
  • Tiredness and fatigue – a lack of energy, “brain fog” or lethargy
  • Nausea and Diarrhoea

Even a mild sensitivity to protein powders may have a major impact upon exercise and appearance, as well as a person's day to day activities. The possibility of a sensitivity to protein types should therefore be high priority for those that take their exercise seriously.
