Personalized nutrition is here to stay, and more information on metabolic processes in the areas of nutrition and health is becoming available for use in personalized nutrition.

The article outlines the different nutritional needs for different athletes, highlighting a personalised nutrition approach must extend beyond professional athletes but also to everyone engaged on physical exercise.

By ensuring that we engage with our bodies true needs, we can then begin to understand what our bodies nutritional needs are and then supplement for this.

The study reviews current evidence on specific nutrients, like vitamins D, C, zinc, and selenium, emphasizing their roles in immune health. Findings suggest that while these supplements can support immune responses, excessive intake may be counterproductive. The authors encourage further research to determine optimal dosages for enhancing immunity without adverse effects.

The paper describes the adverse effects of chronic exposure to high calcium intakes are an increase in the prevalence of kidney stones and hypercalcemia.

By examining population genetics and gene-environment interactions, the article emphasizes the potential for personalized medicine, where treatments could be tailored based on individual genetic profiles.

The article addresses concerns with overuse of supplements by firstly understanding what levels of personalisation is required, identifying different sub groups that can have less or more .effectiveness from personalised nutrition and supplements.

The main findings of this study were that, overall, Personal Nutrition advice was more effective in improving dietary behaviours when compared with conventional ‘one size fits all’ population-based advice.

Supplements continue to be used by an increasing proportion of the population, so their contribution to diet, health and disease needs to be monitored

The article outlines the different nutritional needs for different athletes, highlighting a personalised nutrition approach must extend beyond professional athletes but also to everyone engaged in physical exercise.

The benefits of personalised nutrition are relevant to the individuals needs based on their environment, lifestyle and biology makeup. Understanding these can then cater to unique individual needs, ensuring better health outcomes and sustained performance.

The benefits of personalised nutrition have long been studied. The study from Cambridge University in 2014 suggests behaviour change techniques (BCT’s) must be incorporated to understand more about ones health and how to optimise it.

Very high levels of vitamin D in your blood (greater than 375 nmol/L or 150 ng/mL) can cause nausea, vomiting, muscle weakness, confusion, pain, loss of appetite, dehydration, excessive urination and thirst, and kidney stones. Extremely high levels of vitamin D can cause kidney failure, irregular heartbeat, and even death. High levels of vitamin D are almost always caused by consuming excessive amounts of vitamin D from dietary supplements.

Excessive Dietary Intake of Vitamin A Is Associated with Reduced Bone Mineral Density and Increased Risk for Hip Fracture

Research showed multivitamin users were also more likely to have potentially excessive intakes, particularly for iron, zinc, vitamin A, and niacin.

Intakes from foods plus multivitamins were at risk of being excessive for >15% of the participants in vitamin A, niacin, and folate.

The adverse effects of chronic exposure to high calcium intakes are an increase in the prevalence of kidney stones and hypercalcemia. Although ensuring adequacy is important, there is now an emerging issue of excess vitamin D intakes

Taking too many vitamin D supplements over a long period of time can cause too much calcium to build up in the body (hypercalcaemia). This can weaken the bones and damage the kidneys and the heart.

Pyridoxine (B6) illustrates the problems that can arise when vitamins are used at very high doses for the treatment of clinical conditions.

Research carried out in Swiss GPs showed that “Swiss GPs were unaware of many dietary supplements used by their older patients, which may affect medication optimisation efforts”, suggesting a need to understand a patients needs further.

The study showed that through the substitution with a new formula of the product vitamin E, both the alpha and gamma tocopherol content in the plasma increased significantly. The ratio of alpha to gamma tocopherol thereby shifted in favour of tocopherol at a ratio of around 28:1.

These data demonstrates for the first time that mixed tocopherols exert a protective effect on NF kB activation in smokers.

The study showed great benefits that a targeted supplementation of individualised micronutrients based on laboratory data leads to better levels of vitamin B12, folic acid and D3 in the blood compared to standardised supplementation.

Taking individually adapted micronutrient supplements as part of a supportive therapy led to an intended improvement of specific laboratory values that represent the antioxidative states and systemic inflammation.

• The guar gum we use is of a controlled, certified and highly purified quality.

• Its water-binding property is 8 to 10 times greater than that of wheat bran.

• Guar is a pure fibre, difficult to digest – if at all – and water-soluble.

• Guar binds unwanted cholesterol, bile acid and harmful substances in the small intestine and eliminates them from the body through the large intestine and stool.
