D-Balance 40000

Indications

Vitamin D3 insufficiency may arise in individuals with limited exposure to sunlight or those with deficient dietary intake. This crucial vitamin is indispensable for optimal calcium and phosphate absorption, vital for maintaining robust bones and teeth, and warding off conditions like rickets, osteomalacia, and osteoporosis. During pregnancy and breastfeeding, adequate Vitamin D3 levels are essential for preventing pre-eclampsia and supporting the healthy development of the infant. Furthermore, Vitamin D3 plays a pivotal role in enhancing immune function.

Pharmacology

Calcitriol, the active form of Vitamin D3, exerts its effects by binding to Vitamin D receptors (VDRs) distributed widely across various body tissues. Being fat-soluble, Vitamin D3 boasts a half-life of approximately 50 days. Following absorption in the small intestine, it binds to specific alpha-globulins and is transported to the liver for metabolism into 25-hydroxy Vitamin D3 (Calcidiol). Subsequent hydroxylation in the kidney yields 1,25-dihydroxy Vitamin D3 (Calcitriol), responsible for enhancing calcium absorption. Any unmetabolized Vitamin D3 is stored in adipose tissue and muscles before eventual elimination via feces and urine.

Interaction

Numerous medications can induce Vitamin D3 deficiencies by interfering with its absorption and metabolism. These include but are not limited to Magnesium-containing Antacids, Digoxin, Thiazide Diuretics, Cholestyramine, Phenytoin, Phenobarbital, Orlistat, Corticosteroids, and Mineral Oil. Corticosteroids, for instance, can elevate the body’s requirement for Vitamin D3.

Side Effects

Rare symptoms may include anorexia, lassitude, gastrointestinal disturbances, weight changes, polyuria, headache, and electrolyte imbalances.

Pregnancy & Lactation

Studies suggest safe use of up to 4000 IU during pregnancy, although individual requirements may vary. Nursing mothers should consider both their own dosage and the potential impact on breastfed infants.

Precautions & Warnings

Close monitoring of plasma calcium levels is recommended, especially in patients with renal impairment or those receiving high doses of Vitamin D3. Consultation with a healthcare professional is advised for individuals with specific medical conditions or those taking medications that may interact with Vitamin D3.
