About Us

However you stay active, you need nutrition that actually works. Like most things, you get back what you put in and when we dug deeper, we were disappointed with what we found in the nutrition we were taking. Products full of filler and chalk, rather than solid scientific evidence. So we decided to make create a brand that created products at our professional standard, without artificial fillers and at the highest bioavailability specification.

We create safe, Informed Sport tested, high-end nutrition that everyone can trust, from sports professionals to enthusiasts and everyone in-between.

We want to put premium sports nutrition in the hands of the whole athletic community.


We use only high-quality nutrients without allergy-inducing additives, so they’re suitable for anyone with food allergies or other sensitivities. Good to know right?


We’ve carefully chosen bioactive forms of our vitamins so they can get to work without the need for you to convert them first, meaning your body can concentrate on other more important things.


We make vitamins that tackle your body harder than Jonah Lomuh. The organic mineral carriers found in our range are absorbed up to 27% better compared to other inorganic carriers.

Who we are

George Kruis

Hi there, I’m George – I’ve been playing professional rugby for a little over 12 years now and have been lucky enough to be part of a Saracens team that won three European titles and four Premiership trophies. It’s also been a dream realised to manage 45 caps for England during 2 world cups and a British and Irish Lions tour. Inspired by my time in Japan at the 2019 World Cup (Less said about the final the better ok?), I’ve recently joined the Panasonic Wild Knights in the city of Ota and am currently managing Fourfive remotely (and yes it’s a manic as that sounds).  

Dom Day

Hi I’m Dom – I was a professional rugby player for 14 years, playing over 250 games for a bunch of clubs in Wales, England, Australia and Japan. I’d say some of my best moments were competing for Wales at the 2015 Rugby World Cup, winning the English premiership and obviously, finishing my career as the captain of Saracens second team (affectionately known as The Bin Juice). I retired from professional rugby in 2019 and now manage Fourfive full-time.

Dr Elisabeth Philipps is a clinical neuroscientist and, fuelled by her own experiences of Chronic Fatigue Syndrome (CFS), she furthered her practice by becoming a functional medicine specialist using nutrition and lifestyle to restore health and support active lifestyles.

Elisabeth is passionate about spreading the understanding of how the right nutrients can really make a difference to short and long term health either as recovery from disease or injury or simply maintaining energy for an active lifestyle, improving performance and reducing chance of injury.

Elisabeth has conducted extensive research into how nutrients are best absorbed by the body (bioavailability) and which nutrient forms are the most active (bioactivity). Combined with her knowledge about the best form of food supplements to use and how to avoid manufacturing with artificial chemicals and sweeteners, Elisabeth has designed over 50 food supplement products including vitamins and minerals and herbal preparations.

Elisabeth is excited to be working with George, Dom and the Fourfive Nutrition team to bring this optimised range of Informed Sport certified food supplements to market and change the face of sports food supplements!
