Supplements that can support athletic performance

Posted 28 Mar 2022

In the table below, we’ve listed some nutritional supplements along with their therapeutic dosages and mechanism of action that have been shown to support individuals trying to build muscle.

We’ve selected what we think is the core stack and the nutrients/compounds that have the most evidence behind them. When it comes to supplements, less is more, and it’s important to have a reason or rationale for taking something.

We consider the dosage, form and the additional ingredients (excipients) when selecting these. Where necessary, we have given you some options based on price or form the nutrient comes in. 

It’s really important that before you start any supplement protocol, you check with your GP as taking certain medications in combination with some nutritional supplements can be dangerous. 

You can also do your own research into drug-nutrient interactions by visiting the website.

Lastly – It’s important to reinforce the point that supplements are there to fill the gaps in your nutrition or be used short term as part of a rounded protocol to help resolve functional health issues or support performance goals. If you don’t nail the basics with your food intake, training, sleep or stress management, you may as well not even bother looking at supplements. #unpopulartruth 😉
