Why is protein important? 

Proteins are composed of chemical 'building blocks known as amino acids. Amino acids are used by the body to create and repair muscles and bones and produce hormones and enzymes.

As a result, it is crucial in forming and maintaining every cell in your body. Therefore, it's an essential component of any diet since it fuels your cells, providing the energy required to stay active.

Protein deficiency can lead to;

  • Hair loss
  • Slow wound healing
  • Lowered immunity
  • Hormonal imbalances
  • Low mood

BN Healthy supports you with a simple and beneficial way to reach your daily protein goal.

How to Use Whey Protein?

You may add whey protein powder to your smoothie, baked goods, meals or as a snack replacement that you blend with water to increase satiety and reduce the mid-afternoon munchies

If you're going to work out, you might want to drink a whey protein smoothie before or afterwards, to support the recovery process and deliver quality amino acids to the muscles to support growth

Frequently Asked Questions

Our Qualified Nutritionists are here to help you make the best choice when it comes to you and your health.

BN Protein - Whey Protein Isolate is a complete form of protein that supports healthy muscle tissue building and repair. It's unflavoured for flexibility. It's a great addition to smoothies, baking, and other dairy-based dishes to increase your daily protein intake without mess and fuss. 

Protein is talked about a lot after Weight Loss Surgery. It's a key player in your success.

A protein-rich diet may:

  • Retain and build muscle
  • Support healthy hair, skin and nails
  • Regulate blood glucose levels
  • Keep you satisfied for longer
  • Promote healthy immunity
  • It helps form hormones and healthy neurotransmitters to keep you balanced and energetic

The risk of losing precious muscle tissue is real in any rapid weight loss phase. Whey Protein Isolate (WPI) is a great way to protect your muscle tissue, which helps maintain a healthy metabolic rate and helps with weight management.

WPI provides high satiety levels, making you less likely to crave foods outside your healthy lifestyle plan. Low in lactose, WPI is generally well tolerated after Weight Loss Surgery or in situations where lactose may be of concern. 

Whey Protein Isolate supports bariatric patients greatly because it “ticks all the right boxes” to help you reach your goals. It is geared toward muscle building and retention, blood glucose regulation, recovery from surgery/wound healing, and immune system health.

Collagen is an excellent addition to your regime. It has different hair, skin, nail, and gut health benefits and is less "filling". Both forms of protein have their place, and neither should be a replacement for a balanced and varied diet.

BN Protein - Whey Protein Isolate is recommended as an all-around reliable supplemental protein to support you on your journey. It is one of the most bioavailable, well-tolerated and versatile forms of protein.

Great in coffee and with Weet-Bix

It’s a great-tasting whey protein. I use it when O have milk in a drink, or in food as it has a dairy-taste to me.
