Designs for Health’s NEW VitaminD Synergy was brought to you by popular demand. Research is pointing tomore and more people suffering the consequences of vitamin D deficiencyincluding susceptibility to serious illnesses like MS (MultipleSclerosis).Manypeople are avoiding sun exposure due to fear of ozone layer problems,or because of skin cancer or concern of skin wrinkling. Twenty minutesof sun exposure daily to 6% exposed skin is necessary for maintainingour body’s own production of vitamin D. Some drugs bind fats, includingfat soluble Vitamin D and contribute to low vitamin D levels. Thesedrugs include Cholestyramine, a bile acid sequestering medication, andlaxatives. Intake of Olestra and soluble fiber can also potentiallyreduce vitamin D absorption from food. Statin drugs can causecholesterol levels to fall lower than ideal which may contribute tovitamin D deficiency. Patients with fat malabsorption, problems withbile production or production of lipase for digesting fats are alsosusceptible to low vitamin D levels. For these individuals consider LV-GB (liver-gallbladder support formula) and/or Digestzymes(digestive support formula containing Lipase enzyme). Patients withdark skin pigmentation or a dark tan may require up to four timeslonger sun exposure to absorb the same amount of UVB as light oruntanned skin, because melanin blocks UVB. African descent individualshave a much higher incidence of vitamin D deficiency, especially innorthern states. Obese individuals can have 50% lower plasma levels ofvit D than normal weight people, for the same supplementation levels orsun exposure. Women with low hormone levels are more susceptible tovitamin D deficiency. Estrogen or progesterone deficiency (amenorrhea,surgical or age-onset menopause) impairs the formation of the activeform of vit D. Aging skin has a reduced capacity of vitamin Dsynthesis. By age 75, vitamin D levels can be 25% lower than levels inyounger individuals.
