Micronutrient Deficiencies

Sometimes eating healthy, exercising and taking a multivitamin isn’t enough to support optimal health.

If you are doing those things but still feel fatigued, stressed, or otherwise out of balance, testing for micronutrient deficiencies should be considered. Micronutrient deficiency refers to having a low amount of the vitamins and minerals your body requires for daily biological processes.

Approximately 40 micronutrients are required in the human diet. Inadequate intake of micronutrients is known as an important contributor to increased rates of illness. (1,3)

In developing countries, micronutrient deficiencies are widespread, and cause very serious symptoms and even death. In the U.S., deficiencies can be less obvious and can cause silent issues that accumulate over time, such as DNA damage.

In fact, micronutrient deficiencies can damage DNA in the same way that radiation does. Micronutrient deficiencies have been associated with cardiovascular disease, certain types of cancer, weight gain and obesity, cognitive issues, and lowered immunity. (3)

Common Micronutrient Deficiencies

  • magnesium
  • zinc
  • vitamin B12
  • vitamin D
  • selenium
  • vitamin A
  • calcium
  • folate

Am I at Risk Of Having A Micronutrient Deficiency?

Those particularly at high risk of micronutrient deficiencies are:

  • patients on a low calorie diet
  • smokers
  • patients following a vegetarian or vegan diet
  • those who eat few fruits and vegetables
  • patients who have undergone gastric or bariatric surgeries, and those recovering from illnesses.

However, anyone can be affected by micronutrient deficiencies. (2)

Micronutrient Testing

Micronutrient testing provides information on how well the body utilizes vitamins, minerals, amino acids, fatty acids, and antioxidants. The micronutrient test that we use at Spark Health functionally measures how nutrients are used inside the cells, specifically lymphocytes.

The lymphocytes are placed in various nutrient conditioned media, and are observed for growth. Since the life span of a lymphocyte is approximately four to six months, this micronutrient test provides an average of nutrient status over a longer period of time.

This is very different from simply testing blood levels, which are constantly changing. Furthermore, the micronutrient panel we run does not require any fasting or specific preparation. Patients do not need to stop taking their medications or supplements, and can even receive IV nutrient therapy without it affecting their results.

IV Nutrient Therapy

Based on this micronutrient test, we are able to make personalized recommendations.

We can make a customized IV bag based on what your micronutrient test says you are deficient in. We can deliver concentrated levels vitamins, minerals, anti-oxidants and amino acids directly into the bloodstream through an IV.

With certain nutrients, IV therapy provides up to 10 times the absorption of oral supplementation. By administering the nutrients directly into the bloodstream, our cells are able to effectively metabolize the nutrients they require for optimal function and healing.
