70% of Americans are deficient in Vitamin D. Adults of all ages who have darker skin (increased skin melanin) or who always wear sun protection or limit their outdoor activities, such as homebound elderly persons, are also prone to Vitamin D deficits.
There are many signs and symptoms within the body that could indicate a vitamin D deficiency including osteoporosis, osteopenia, breast or colon cancer, heart disease, inflammation, autoimmune conditions (multiple sclerosis, rheumatoid arthritis, Hashimoto’s, lupus, etc.), lowered immune function, depression and insulin resistance.
Sometimes a Vitamin D deficiency is only marked by feeling a bit tired or sluggish, feeling down or in low spirits regularly, or just getting sick often. It’s important to note that while these symptoms might indicate vitamin or nutrient deficiencies, there may also be other health conditions or issues at play. This Vitamin D Test requires serum, drawn at a local Quest lab. It can be used to determine if vitamin D levels are adequate or deficient.
