L-Tyrosine: Effects on Exercise and Health, and How to Take It

Greg Potter

In Part 1 of this series, we looked at how L-tyrosine affects cognitive performance, mood, and emotion regulation. Today we’ll explore other effects of L-tyrosine, including whether it affects your exercise performance, your ability to regulate your body temperature, and your thyroid function. We’ll end by assessing the best ways to take L-tyrosine, and whether some people should think twice before they try it.     Key takeaways L-tyrosine might be helpful for exercise done in cold conditions that requires fine-motor skills and/or a lot of cognitive effort. If you’re middle aged or older, taking L-tyrosine before cold exposure can...

Fuel for the Work Required: A Game Changer for Endurance Athletes?

Adam McDonald

Here at Resilient Nutrition we’re all about using cutting-edge science to maximise performance - after all, it’s the foundation we’ve built our products on. In today’s blog we’re bringing you insights into how you can make dramatic improvements to your endurance through nutritional “periodisation” strategies used by professional athletes. These methods are based on a concept known as “fuel for the work required”.   Key takeaways Chronic consumption of a low-carbohydrate diet can impair endurance performance. Instead, to maximise the ability to use both fat and carbohydrate during training, carbohydrate periodisation is recommended. Even ultra-endurance athletes are likely to benefit from...

High Altitude Nutrition: A Primer

Greg Potter

On the morning of 31st May 2021, Resilient Nutrition athletes Adri Brownlee and Dan Dowding stood on top of the world. After years anticipating the moment, they’d finally realised their dreams and climbed Everest. Determination, careful planning, and expert guidance from Nims Dai and the Elite Exped team of experienced mountaineers and guides led them to the summit, but their preparation was instrumental too, a key component of which was their nutrition. Since the Resilient Nutrition team supported Adri and Dan before and during their Everest expedition, in this blog we’ll cover some of the nutrition strategies the two of...

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...

The effect of the menstrual cycle on training and performance

Emily Jevons

Photo Credit: Presca Sportswear Ten minutes into your session and you feel low in energy, a bit lethargic. You did the same session the week before at ease and felt like you were flying! You had the same amount of sleep, the same breakfast, felt hydrated, have no changes in your mental health… so what’s the difference? It may simply lie with your unique female physiology. As a woman your hormones fluctuate throughout your menstrual cycle. During the first two weeks, the follicular phase of your cycle, oestrogen dominates. Whilst during the second two weeks, the luteal phase of your...
