Vitamin D contributes to the maintenance of normal bones, teeth, muscle function and immune function. Vitamin D contributes to normal absorption/utilisation of calcium and phosphorus.
The classic vitamin D deficiency disease is rickets. Yet as fear of sun-exposure has grown and lifestyles have become more sedentary, exposure to the sun has dropped dramatically and vitamin D deficiency and the incidence of rickets has surged. The skin cannot create vitamin D if covered in sunscreen or clothing, it is thought that a sun cream with SPF15 will reduce the skin’s ability to synthesize vitamin D by more than 95%.
Furthermore, many older people and those with dark skin or those who tend to wear more modest clothing are amongst the population groups that are most likely to suffer sub-optimal vitamin D levels.
Dietary sources include fortified foods, eggs and fatty fish. Most commonly-available Vitamin D3 supplements are derived from the lanolin in sheep’s wool.
This supplement from Viridian Nutrition provides vegan Vitamin D3 naturally-derived from lichen.
Potential applications: Osteoporosis, osteomalacia (bone softening), muscle weakness/wasting, cellular support, heart disease, stroke, hypertension, autoimmune diseases, depression, chronic pain, osteoarthritis, psoriasis, and periodontal disease. Hyperparathyroidism due to low levels of vitamin D. Vitamin D malabsorption is common in Crohn’s Disease and can lead to a deficiency of the vitamin.
Known contraindications: People with hyperparathyroidism should not take vitamin D without consulting a physician.
Interactions: Vitamin D should be used with caution in patients taking digoxin, because hypercalcemia (which may result with excess vitamin D use) may precipitate abnormal heart rhythms.
Concurrent administration of thiazide diuretics and vitamin D to hypoparathyroid patients may cause hypercalcemia, which may be transient or may require discontinuation of vitamin D. Stimulant laxatives can reduce dietary vitamin D absorption. Use of corticosteroids can cause osteoporosis and calcium depletion with long-term administration. This calcium depletion creates a greater need for both supplemental calcium and vitamin D (which is necessary for calcium absorption).
Pregnancy and lactation: Recommendations for vitamin D in pregnancy, at the time of writing, are set at 10ug (400iu) daily. Doses higher than 10ug should be via consultation with a GP.
Useful links: Osteoporosis: Calcium, magnesium and boron powder, organic flax seed oil, Synbiotic Daily (improves calcium metabolism).
