Proprietary Blends – Side Effects

So you’re thinking about buying a supplement and have come across the term ‘Proprietary Blend’ all over the place, but what does it mean? And can proprietary blends give you side effects?

Let’s start with defining what a proprietary blend is. If you’ve only just seen this term but have been buying supplements for a while, chances are you’ve probably bought a product that uses one. They’re not very obvious unless you know what you are looking for. So…

A “proprietary blend” on a dietary supplement’s Supplement Facts panel is a list of ingredients that are part of a product formula specific to a particular manufacturer.  FDA requires manufacturers to list all of the ingredients in a product on its label, along with the amount of each (in terms of weight), unless the ingredients are part of a proprietary blend—then the specific amount of each individual ingredient in the blend does not have to be listed, only the total. So it is important to be aware that the exact amount of each ingredient in a proprietary blend (or blend or delivery system) is unknown. This is especially important when a proprietary blend contains stimulant or stimulant-like ingredients, such as caffeine, synephrine, or yohimbine. In fact, the only way to know what is in any particular dietary supplement product is through laboratory testing, which is why it is important to look for third-party certification.

This is the definition provided by government agency hprc-online.org.

To take this and simplify it, means that basically supplement companies don’t have to show you exact amounts of the ingredients that go into their product. And can instead least the individual ones without the full dosing.

So if you had a green tea and cayenne supplement, they’d just say it was a combined amount of 500mg, for example. Not 250mg Green Tea and 250mg Cayenne.

But why does this mean that some proprietary blends can cause side effects?

The answer is pretty simple, if you are taking a product that doesn’t show you the dose of every ingredient, how do you know if you’re going to be safe taking it? What if a 1500mg blend in a supplement is 90% caffeine? You’ll never sleep again! Sort of.


Proprietary Blends Ingredients that Cause Side Effects

So, which ingredients in proprietary blends are likely to cause side effects?

Well, generally you want to be on the look out for stimulants. As the most common way to make a fat burner boost your metabolism, stimulants are effective and work. But, when taking in high doses they can cause side effects like headaches, nausea and anxiety.

Key ingredients you want to be looking out for in proprietary blends are:

  • Synephrine/Bitter Orange
  • Caffeine
  • Guarana
  • DMAA
  • Ephedra Leaf

Proprietary Blends Avoiding Side Effects

The best way to avoid side effects from proprietary blends is to not purchase supplements that contain them.

Pretty simple right?

But if there is a product that you are desperate to have, that uses one of these blends and you suspect it could cause side effects, we’d recommend taking a single capsule following a meal or snack. This can help with the absorption of the ingredients and also alleviate the side effects slightly.


Proprietary Blends – Side Effects Conclusion

The shortest possible way to avoid side effects from proprietary blends is to avoid them.

We’re sure that some of these blends out there are perfectly safe and will work, but overall you just shouldn’t be trusting them.

Whilst most companies will tell you it’s to protect ‘their special blend’, this isn’t true. Any supplement company with half a brain could use a proprietary blend to figure out what’s in the product anyway.

From experience these blends are mostly just packed full of caffeine, and that’s not going to get you very far when it comes to burning away your unwanted fat.

By not buying a proprietary blend, you are buying a more effective, more honest fat burner, with less chance of side effects.
