Are There Hormones in Your Whey Protein Powder?

Author: Nicole Adler   Date Posted: 5 December 2016 

Whey protein powder is currently one of the most popular Australian online supplements. However, this does not mean that this supplement is totally free from controversy, since a lot of people wonder if there could be hormones inside Australian online supplements, and whey protein powder specifically. To answer that question accurately, we need to take a closer look at the whey protein supplements that are currently being offered as Australian online supplements, because there is no simple yes or no answer to this question.

Naturally Occurring Hormones

Whey protein powder from any Australian online supplements range will contain some hormones, because this product has been obtained from cow’s milk, a product that naturally contains certain hormones. So, the real question is not if whey protein powder from an Australian online supplements range contains hormones, but if those hormones could have a harmful effect on our health.

The issue with Australian online supplements containing hormones is the level of hormones they contain. Anything we humans consume these days contains some form of hormones, especially when that product has been derived from animal products such as eggs, milk and meat. 

Concerns Regarding Hormones in Whey Protein

Not all hormones have a negative effect on the human body, but some athletes have some concerns about hormones that could be hidden in whey protein. These hormones are steroid based sex hormones such as testosterone, growth hormones, growth factors and non-hormonal compounds such as antibiotic contamination. To clear up any doubts or fears you may have, here is an overview of what your whey protein really contains.

Steroid Based Sex Hormones

Any steroid hormones that could be present in whey will be found in the fatty portion of whey or fat in the milk source product, since steroid hormones are known for their solubility in fat. However, high-quality whey protein powders are virtually fat free, which means that any steroid based sex hormones remaining in the protein powder are almost non-existent.

The amount of fat remaining in a whey protein supplement may depend on the filtering processes your supplement manufacturer uses during the creation of the supplement. For example, whey protein powders filtered with the ion exchange method contains the least amount of fat of all, even though this is not the best type of whey protein on the market. So, if you are really concerned about steroid based sex hormones in your whey, then you can always fall back on this option.

Still, the best type of whey protein on the market is usually made with a cross-flow filtration. The amount of fat remaining in this supplement is also minor, so the levels of steroid based sex hormones will be minimal and not enough to affect your body.

Growth Hormones

Growth hormones are quite different from the steroid based sex hormones we mentioned earlier. Growth factor hormones such as IGF-1 and BST are protein-based hormones, which are often found in muscle and milk. However, the amount of such hormones is minimal, so only a small fraction of whey protein contains this growth hormone.

Please note that growth factor hormone is not the same as human growth hormone. HGH or human growth hormone is produced in the pituitary gland, and the hormone is often used in anti-ageing products.

So, how much BST is present in the average whey protein supplement? Well, the levels of BST range from zero to ten parts per billion, so we are literally speaking about a tiny amount. So, scientific fact counters some of rumours surrounding whey protein and the presence of harmful growth hormones.

Another growth factor that can be found in whey protein is IGF-1, a hormone that does not affect human health. Whey protein powders may also contain variable amounts of this hormone, since the amount of IGF-1 is subject to the production methods used to create a whey protein.

Whey with Increased Hormone Levels

There are some whey protein supplements that have increased levels of IGF-1. These types of protein supplements are often referred to as Bioactive Whey Fraction Protein or BAWF. This increase in IGF-1 could have benefits for your muscle building process, since IGF-1 is known as the anabolic/catabolic hormone.

Researchers have not found a clear link between long-term use of IGF-1 and certain medical conditions. The growth factor does not seem to have a negative effect on the psyche of athletes either, so Bioactive Whey Fraction Protein is deemed safe for consumption.

Antibiotics in Whey

Some people are worried their whey contains antibiotics, since milk from cows that have been treated with antibiotics can contain traces of it. However, this is usually only the case for untreated milk and most whey manufacturers have high standards when it comes to quality control. Therefore, high quality whey will not contain traces of antibiotics.

The Nutrients Direct Lab Report

Nutrients Direct focusses on providing athletes with all the information they need about their whey protein supplements.
