What’s Included in this Package

Vitamin B12 and Folate Test

Vitamin B12 and folate support many cellular functions in the body. B12 supports nerve function, and folate (aka folic acid or vitamin B9) converts carbohydrates into energy and to form DNA. Both B12 and folate are essential to red blood cell production. A B12 deficiency or a folate deficiency may lead to fatigue, weakness or anemia. 

 

A vitamin B12 or folate deficiency may occur when the body either doesn’t get enough through dietary intake, or from poor absorption. Vitamin B12 is not produced by plants. Foods rich in vitamin B12 include meat, eggs, dairy products and other foods from animals. Foods rich in folate include broccoli, spinach, asparagus, lima beans, fruits and enriched grain products. Folate is critical during periods of rapid growth, such as during pregnancy and fetal development. However, some people simply can’t absorb either B12 or folate, no matter how much they eat.¹

 

Vitamin B12 and folate work closely, making red blood cells and helping iron work better in your body.

Vitamin B12

Measures the amount of vitamin B-12, a water-soluble vitamin that plays a vital role in the health of nerves and red blood cells.

Folate (Folic Acid)

The B vitamin that plays a vital role in making DNA, the genetic material in cells. Folic acid is a synthesized version of folate found in processed foods and supplements. A folate deficiency can lead to health complications, especially in pregnant women.

Vitamin D Test

Vitamin D is both a nutrient you eat as well as a hormone that's produced by your skin in response to sunlight exposure. It plays a significant role in bone health by helping regulate calcium and phosphorus, which are essential minerals that work together to build strong bones. Vitamin D also has a role in your nerve, muscle and immune systems, as well as your mental health. 

This vitamin D blood test evaluates 25-hydroxyvitamin D (25-D): the best measure of how much vitamin D is stored in your body. A prolonged deficiency in vitamin D has been shown to lead to fatigue, bone pain and even depression.  

While Vitamin D occurs naturally in very few foods, many are fortified with it, including dairy products and cereals. If vitamin D levels are low, vitamin supplementation may be helpful, especially when access to natural sunlight is limited. Vitamin D rich-foods include vitamin D fortified milk or plant-based alternatives, vitamin D fortified breakfast cereals and fatty fish (trout, salmon, tuna and mackerel and fish liver oils).
