Vitamin D: Most of us need more

"Vitamin D10 is by far the best natural product that I have taken for my Vitamin D levels. I tried other brands at lower doses, but realized that even taking 5 or 6 per day was not getting my levels to optimal. D10 took three months to get me from 51 to 126 ng/mL. My energy is back, my mood is good, and I made it through the dreary NW winter with no signs of illness. Thanks Synergy for such a good product."

There is overwhelming evidence from several scientific studies that indicate many of us may be vitamin D deficient despite consuming a diet of fortified foods and taking routine multi-vitamin supplements. The primary reasons for the prevalence of vitamin D deficiency include a low Recommended Daily Allowance (RDA) and our modern indoor lifestyle. The current vitamin D RDA was set merely for the prevention of rickets and osteomalacia. Changes in lifestyle such as shifting to indoor work activities, wearing abundant clothing, using sunscreen and avoiding sun exposure have also contributed to low vitamin D levels..

In recent years, experts around the world have recognized the expansive role of vitamin D in medical science and have been working to clarify the reasons why higher amounts vitamin D3 are required.¹ Historically, it was thought that the role of vitamin D3 was limited to bone and mineral metabolism and therefore it was classified as a vitamin, small amounts of which would help prevent rickets and osteomalacia.

Today, scientific researchers are providing important evidence to support that optimal vitamin D levels are necessary for the normal functioning of several different physiological pathways in our body and sub-optimal levels of vitamin D have been implicated in several types of cancer, heart disease, hypertension, autoimmune diseases, obesity, diabetes, depression, chronic pain, osteoarthritis, osteoporosis and immunity.² Browse through our website and explore details about these disease states and their relationship to vitamin D levels. You will discover how an optimal vitamin D level can have a positive impact on your health and wellness.

Advancements in medical science have made it possible to measure the production of vitamin D and have identified that our bodies produce over 10,000 to 20,000 IU of vitamin D3 in 20 to 30 minutes of full body summer sun exposure.³ Scientists estimate that as much as 25,000 IU of vitamin D can be produced with full body exposure within an hour before our skin turns pink. However, our modern lifestyle keeps us indoors most of the time and when we are outdoors, full body clothing and sunscreens do not allow enough UVB rays to reach the skin and therefore sufficient amouns of vitamin D3 are not produced.⁴ There is evidence to support the concept that many people are not producing adequate vitamin D3 even in countries with abundant sunshine. Consider a recent study in Saudi Arabia; with probably the maximum annual sunshine in the world, 83% of participants - residents of Saudi Arabia were found to be vitamin D deficient.⁵ Similar evidence has been documented in the United States. A 2009 nationwide survey involving almost 6300 children between age 1 and 21 found 61% (representing 50.8 million US children and adolescents) of the subjects were vitamin D insufficient and 9% (representing 7.6 million children and adults) were vitamin D deficient.⁶

Various studies support that desirable vitamin D levels (25 OH-Vitamin D) should be higher than previously recommended. According to Robert Heaney, a prominent vitamin D researcher, the current RDA was set at 200-600 IU to prevent Rickets.⁷ A vitamin D level of > 12 ng/mL is sufficient to prevent rickets and osteomalacia; however, we need a minimum level of 30ng/ml for the optimal functioning of our body. In fact, many experts recommend maintaining levels between 50 and 80 ng/ml throughout the year.

Vitamin D experts also recommend that vitamin D medical supplementation should reproduce the natural pulsatile production of vitamin D3. The newer combined evidence approach also supports reclassifying vitamin D as a hormone.⁸ Similar evidence has been documented in the United States. The physicians at Synergy Therapeutics Rx have combined physiological and pharmaceutical expertise with extensive clinical experience to develop a unique vitamin D supplement; Vitamin D10. Vitamin D10 provides 10,000 IU of vitamin D3 and matches the natural pulsatile production of vitamin D3.
