Nutrient Metabolism


Vitamin A

Vitamin A is essential for our vision, our immune system and healthy reproduction. Nutrigenomix provides information on whether you convert Vitamin A from your food effectively into the active form of Vitamin A needed by the body due to a variation of your BCMO1 gene.

Vitamin B12

Vitamin B12 is an essential nutrient needed for healthy brain and nervous system function. The effects of low levels of B12 can take a long time to present themselves and if left untreated, Vitamin B12 deficiency can lead to damage of the nervous system including the nerves around the brain and spinal cord, affecting muscle co-ordination and sensations.Symptoms of Vitamin B12 deficiency include:

  • Dizziness
  • Paleness
  • Shortness of breath
  • Fatigue
  • Anaemia
  • Hearing difficulties
  • Weight loss
  • An enlarged spleen and liver (hepatosplenomegaly)
  • Exaggerated reflexes
  • Mild depression and confusion
  • Hallucinations, personality and mood changes
  • Irritability
  • Damage to the optic nerve (nerve leading to the eye)

Nutrigenomix will tell you how effectively you extract and utilise Vitamin B12 from your diet, based on the FUT2 gene.

Vitamin C

If you have a variation of the GSTT1 gene, you will utilise Vitamin C more, or less, effectively compared to other people. Low levels of Vitamin C have been linked to an increased risk of heart disease, Type 2 Diabetes and cancer.

Vitamin D

If you have a variation of the CYP2R1 and GC genes, you will utilise Vitamin D more, or less, effectively.

Vitamin E

People who have a variant of the F5 gene, are at an increased risk of blood clots.


Depending on your variation of the MTHFR gene, you may not be utilising Folate efficiently from your diet. Low folate utilisation can increase your risk of heart disease.

Iron Levels

Variations in the genes TMPRSS6, TFR2 and TF can result in inefficient iron utilisation. Low iron levels are linked to fatigue, pale skin, weakness, shortness of breath and dizziness.

Iron Overload

Due to a variation in the HFE and SLC17A1 genes, some people can develop an increased load of iron, which in turn can lead to liver disease, arthritis and heart disease.


If you have a variation in the GC gene, you will utilise calcium from your diet more, or less, effectively than someone else.  Low calcium levels result in weak, brittle bones and an increased bone fracture risk.
