L-Tyrosine: Effects on Memory, Mood, ADHD, and More

Greg Potter

Lots of people have recently become interested in whether supplementing with L-tyrosine can improve performance at work and lift mood, in part because of the opinions put forward by scientists and influencers on podcasts and social media. While tuning into commentary by these people, I’ve at times felt frustrated by their lack of depth and clarity, so in the next 2 blogs we’ll focus on what the science of L-tyrosine actually shows. The good news is that L-tyrosine can be handy in many contexts. Used intelligently, it can help you beat brain fog and more. In this blog, we’ll focus on the effects of...

Perform Better on Less Sleep? All About Creatine and Sleep

Greg Potter

Now and then, you don’t get enough sleep. When that happens once, it doesn’t affect you much. But while you might feel like the effects of back-to-back nights of poor sleep only accumulate to a point, the gloomy reality is that they continue to build. So, wouldn’t it be great if you could take something to help you minimise the results of insufficient sleep? Better yet, what if there was something that enabled you to perform better on less sleep? Some fascinating research suggests there just might be. Its name is creatine monohydrate. While there’s a lot to learn about...

Back to Work: Simple Tips to Increase Productivity

Greg Potter

Many of us are returning to work this week after the summer. As getting back in the swing of things can be tricky, I thought I’d share some simple tips to increase productivity at work. The next two blogs are for anyone who does "deep work", a concept popularised by Cal Newport. In Cal’s words, deep work is “professional activity performed in a state of distraction-free concentration that pushes your cognitive capabilities to their limit. These efforts create new value, improve your skill, and are hard to replicate.” I don't know about you, but that's the kind of work I...

Eat Chocolate, Be Smarter? What You Should Know About Cocoa and Brain Health

Greg Potter

Let’s face it, I’m a chocoholic. So, when it came to exploring the science of cocoa products, I was bound to be a bit biased. But as I fought my urge to cherry pick research supporting the health benefits of cocoa, I came to see that it really is highly nutritious. However, there’s also a dark side to cocoa (pun intended) that has implications for which cocoa products you should pick. In the next couple of blogs, I’m going to highlight the science of cocoa, beginning with how cocoa affects brain health and the best ways to consume cocoa for maximum...

Sleep Deprivation Coping Strategies for Athletes

Greg Potter

Losing sleep sucks, and it’s true that regularly not getting enough sleep probably ultimately affects all aspects of health and performance. But there are times when sleep deprivation is unavoidable, and less time sleeping means more time for what you really want to do, which in some instances (e.g., ultra running) leads to better performance. So, wouldn’t it be helpful to have some strategies that help you succeed when you’re short on shuteye?   In the last few years, we’ve worked with a range of competitors who simply have to perform despite debilitating sleep disruption, and in this blog, we’ll cover some of the more effective sleep deprivation coping methods for athletes. We won’t focus on any one sport, for the strategies below should be helpful whether you’re an ocean rower, an ultra cyclist, or...

In Defense of Caffeine

Greg Potter

Have you ever felt confused about whether caffeine is good or bad for you? I certainly have, and because of this, my caffeine intake has fluctuated between total abstinence and weeks of consuming over 600 mg caffeine each day (that’s a lot). When I was doing my PhD on the relationship between nutrition and sleep, I read study after study about caffeine, and this process helped me understand how to use caffeine to get more out of life. I’ve since seen many nutrition companies maligning caffeine and, honestly, I think most of this propaganda reflects the fact they don’t read scientific publications. I’m therefore keen to clear up what we actually know about this substance. Most important, I want to share how you...
