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

ASMBS recommends post-surgical bariatric patients states between 60-80g per day.

BN Healthy supports Weight Loss Surgery patients with a simple and beneficial way to reach their daily protein goal.

Whey Protein Isolate: A Superior Protein Delivery

Not all WPIs are made equal. Some WPIs are manufactured under harsh conditions, robbed of much of their bioactivity, and thus become less effective. 

This whey protein isolate powder is scientifically processed under strict conditions to maintain its high level of naturally occurring essential and branch chain amino acids. 

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 overindulgence. 

If you're going to work out, you might want to drink a whey protein smoothie afterwards, or you could simply combine your whey protein powder with water.

What is the Best Whey Protein Powder?

Pure whey protein isolate is the best option for bariatric patients. It is easily absorbed, and because all of the lactose is eliminated during the process, it is gentle on the stomach—especially if you are lactose intolerant.

BN Protein WPI is unflavoured for flexibility. It's a great addition to smoothies, baking, and other dairy-based dishes to discreetly increase your protein intake each day.

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


  • Retains and builds muscle
  • Reduces blood glucose levels
  • Keeps you satisfied for longer
  • Promotes immunity
  • Helps form hormones and healthy neurotransmitters to keep you feeling balanced and energetic.

In the rapid weight loss phase, the risk of losing precious muscle tissue is real. WPI is a great way to protect your muscle tissue that helps maintain a healthy metabolic rate and helps with weight loss.

WPI provides high satiety levels, leaving you less likely to crave foods outside of your healthy lifestyle plan. Low in lactose, WPI is generally well tolerated after WLS.

WPI is the gold standard for Bariatric Patients in that it “ticks all the right boxes” to help you reach your goals. It is geared for muscle building and retention, blood glucose regulation and recovery from surgery.

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 Pure Pro - WPI is recommended as an all-around reliable supplemental form of protein to support you on your weight loss surgery journey. It is the most bioavailable, well-tolerated and versatile form of protein.

BN Protein Whey Protein Isolate Powder

Not sure how I like it, which is why I gave it a 3 star rating. You can't add it to hot drinks but you can add to cooking which I forget to do. I'm not sure if Mr tummy likes it so will be trying it again on a day when I eat what I know my tummy is happy with.
