Micronutrients that are free floating in your blood and exist outside the cells, determined in serum are called extracellular micronutrients.
These extracellular micronutrients are a static measure of what is in your blood at any given time. These are dependent on your short-term intake of supplements or diet and give a direct assessment of your baseline micronutrient levels.
Extracellular nutrient tests reflect a person’s diet over a relatively narrow time frame.
Intracellular micronutrients are the micronutrients absorbed by your circulating white blood cells and red blood cells.
Cellular micronutrient absorption is an important step in maintaining and promoting optimal functioning of all our cells.
It is important to understand that, even though you may be consuming an adequate or healthy diet or supplements, your cellular intake levels of those nutrients may not be sufficient and may still provide risks for deficiencies and the disorders associated with them.
Your genetics, aging, lifestyle, chronic illness, and medications all affect your cellular nutrient absorption. The intracellular portion of Vibrant’s and Spectracell's micronutrient test takes all the above factors into consideration to identify your cellular nutrient absorption status. This test can reveal a person’s functional nutritional status over a much longer time (4-6 months) than extracellular testing.
