The Importance of Personalised Nutrition

For any individual to physically perform at his or her best, a nutritionally adequate diet and sufficient hydration are critical. You may be on a personalised nutrition plan to improve your training and performance, such as increasing muscle mass or speeding up recovery time; or you are simply aware of what foods and drinks to focus on to keep your energy naturally high and your immune system healthy.

Whilst diet is the foundation of our vitamin and mineral needs, even proper and consistent nutritional preparation can leave us falling short of some key vitamins and minerals needed for health like bone support, energy production and immune health.

But haven’t you ever wondered why most multivitamin food supplements that we use to top up our diets are simply designed for human adults – lumping everyone’s nutritional needs in together? there is an undeniable lack of personalised nutrition products and advice, unless seeking professional advice.

At Fourfive Nutrition we’re ahead of the game, especially! We’ve done our research and have found that adult females and males vary in the levels of certain nutrients needed to keep active and healthy.1 So we’ve designed a personalised nutrition product range of Multivitamin products to suit everyone’s needs.

We know the importance of taking on board measured levels of water soluble and fat soluble vitamins, including all the B vitamins, vitamin A, C, D, E, K, as well as essential minerals like magnesium and calcium, all to support areas such energy production, immune system function and bone strength through a personal nutrition programme.

Whilst the levels of many nutrients are similar between genders there are some specific differences that require a personalised nutrition approach which is why we’ve assessed and incorporated into our Multi products.

What Nutrients go into our Personalised Nutrition Products?


Iron deficiency is common in athletes and can affect performance.
It’s more common in females, especially those in endurance sports. A Swiss review found that the rate of iron deficiency among teenage female athletes was up to 52%.2

Additional research found that low iron levels can cause many adverse symptoms in female athletes, including reducing endurance and increasing the amount of energy that the body uses.

It’s for this reason that we’ve designed our Female Multi product to contain higher levels of iron (according to the Nutritional Reference Value (NRV) guidelines). Our Female Multi really does offer personalised nutrition.


NRV guidelines suggest that men need more daily zinc intake compared to women. Zinc is a crucial mineral for metabolism and healthy immune system. Zinc deficiency is also problematic as plasma testosterone is regulated in part by zinc. Therefore, a zinc deficiency may adversely affect this hormone, reducing muscle mass and strength.

For this reason we include higher levels of zinc in our Male Multi according to the Nutritional Reference Value (NRV) guidelines. Our Male Multi makes for truly personalised nutrition.


This crucial mineral is needed in men and women for areas such as immune health. However, men require a greater daily intake as it’s an important nutrient in male fertility and hormone reproduction. So, in order to provide personalised nutrition in our core range, we include higher levels of selenium in our Male Multi according to the Nutritional Reference Value (NRV) guidelines.

Furthermore, we include only the most bioactive forms of nutrients in our products (i.e. ones that are already active so get to work straight away); like methylcobalamin form of vitamin B12 and P5P form of vitamin B6, as well as many of our minerals being in citrate form (magnesium citrate, calcium citrate etc.) to optimise the ability of the body to absorb and use this essential mineral. You can read more about these forms and the importance of bioavailability here.
