Vitamin D Deficiency | Testing

Did you know that over 50% of Americans are deficient in Vitamin D, and deficiency is associated with depression, fatigue, weight gain and more? Medical evidence has shown that Vitamin D plays a crucial role in energy, strengthening bones, fighting depression, weight loss and boosting immunity. Vitamin D is mostly obtained from the sun and most of us are not exposed to enough sunlight daily. Once levels decrease you need high dose vitamin dosage prescribed by a physician to replace levels. Our medical office offers testing for vitamins and important nutrients as well as IV Vitamin D Replacement, Vitamin D Injections and daily supplements!
