- There is a direct association between skin aging and vitamin D 25(OH)D levels.
- A study in the March 2010 Journal of Clinical Endocrinology and Metabolism showed a link between vitamin D levels and the accumulation of fat in muscle tissue, which is important for muscle strength.
- The New England Journal of Medicine states that 50% of critically ill patients in intensive care units (ICUs) are deficient in vitamin D.
- 1 of every 7 teenagers in the U.S. is deficient in vitamin D. Overweight teens are 2x as likely to be deficient as teenagers of healthy weight. Girls had twice the risk of boys.
- Low vitamin D levels reduce muscle power and force in adolescent girls.
- Vitamin D deficiency is a serious problem among the elderly in the U.S Americans aged 50 and older are at increased risk of developing vitamin D insufficiency. As people age, their skin cannot synthesize vitamin D as efficiently and the kidneys are less able to convert vitamin D to its active hormone form.
- Older women who skimp on vitamin D rich foods (fatty fish) are more likely to develop breast cancer, according to Frank Garland, Ph.D. of the Department of Community and Family Medicine at UCSD.
- Higher serum 25-OH Vitamin D levels are associated with LONGER WBC telomere length and lower C-reactive protein levels in women. The exact mechanism of action is unknown, but it is thought that vitamin D's ability to attenuate the pro-inflammatory response helps prevent telomere attrition. Longer telomere length may delay the onset of age-related chronic disease.
- Vitamin D helps to increase testosterone levels according to a study published in the journal Clinical Endocrinology.
- People with the lowest blood levels of vitamin D have more colds and cases of the flu.
- Vitamin D levels are inversely associated with depression in women aged 50 and older
- Immune system regulator - the higher your vitamin D level, the lower your risk of contracting colds, flu, and other respiratory tract infections. We often think of vitamin C for colds, however low vitamin D levels are associated with decreased immune function and an increase in mortality.
- Reduce your risk of Cancer. Vitamin D can reduce 78% of all cancers! It was found to significantly decrease PSA levels in 20% of men diagnosed with prostate cancer.
- Vitamin D is important for the absorption and metabolism of calcium and phosphorous, which is required for healthy bones and prevention of osteoporosis. Vitamin D is a synergist to calcium and magnesium.
- Optimal vitamin D levels reduce your risk of developing rheumatoid arthritis, Multiple sclerosis and cancer. Deficiency is particularly common in those with inflammatory and autoimmune disorders.
- Research from the Medical College of Georgia revealed that vitamin D is linked to maintaining a healthy body weight and helps prevent obesity.
- Vitamin D helps the body control calcium levels. When the body is deficient in either vitamin D or calcium, there is an increase in the enzyme, fatty acid synthase, which converts calories into fat. Lack of vitamin D causes more calories to be stored as body fat, particularly in the abdominal region.
- Vitamin D plays a key role in brain function later in life.
- Being of African-American decent; people with dark skin
- Cloud cover or living farther away from the equator
- Digestive dysfunction that limits absorption – some people’s digestive tract cannot absorb vitamin D due to medical problems such as Celiac disease, cystic fibrosis and Crohn’s disease.
- Inadequate sunlight exposure and sunscreen use. Your body makes vitamin D when your skin is exposed (without sunscreen) to sunlight. Our ability to absorb vitamin D from the sunlight diminishes as we age.
- Insufficient intake from foods and/or supplements. This especially applies to those following a strict vegetarian diet because vitamin D is highest in egg yolks, beef liver, wild fish and Bio D Mulsion Forte.
- Medications: prednisone, cholesterol-lowering drugs, seizure meds. Several drugs increase the risk for and severity of vitamin D insufficiency including:
- Allopurinol (gout) – Results in lowered levels of vitamin D.
- Anticonvulsants – Increased risk for vitamin D deficiency with resulting increased risk for osteoporosis.
- Cimetidine – Reduces the conjugation of vitamin D.
- Oral corticosteroids – Reduced calcium absorption and inhibited vitamin D formation in the liver.
- Heparin – Interferes with vitamin D function and increases the risk for osteoporosis and osteomalacia.
- Avoid Mineral oil – Interferes with vitamin D absorption.
- Older adults – As people age their kidneys are less able to convert vitamin D to its active form.
