Information about Shelcal 500 Tablet
It helps in keeping your bones strong and prevents osteoporosis. Calcium is used for building and maintaining healthy bones. Our body can get calcium from one of two sources namely food/diet or bones. When food fails to meet your body’s calcium requirements, it borrows it from your bones. If this happens over a period of time then it leads to bone loss. 
It contains calcium as well as Vitamin D3. Calcium is also essential for heart, muscle, and nerve functions and also aids in the clotting of blood. This mineral also helps to treat and manage osteoporosis and to prevent calcium deficiency in pregnant and breastfeeding women.  The primary function of Vitamin D3 in the body is to maintain healthy and strong bones. It does so by ensuring calcium absorption in the gut and by maintaining adequate levels of two minerals essential for bone health, calcium, and phosphorus.
Key ingredients:
Calcium: 500 mg
Vitamin D3 (cholecalciferol): 250 IU
Key benefits/uses of Shelcal 500 Tablet:
1. To treat calcium deficiency due to:
Inadequate dietary intake
Hypoparathyroidism (reduced production of parathyroid hormones which regulate the levels of calcium and phosphorous in the body)
Kidney failure
Pancreatitis (Inflammation of the pancreas)
Certain medicines such as corticosteroids, anticonvulsants, and rifampicin
Liver disease, causing low albumin levels which might affect calcium levels
2. To treat Vitamin D3 deficiency due to:
Decreased function of the kidneys
Inadequate absorption of Vitamin D3 by the digestive tract (due to conditions like Crohn’s disease, celiac disease, and cystic fibrosis)
3. To increase the levels of Vitamin D3 in the milk of breastfeeding women. Vitamin D3 requirements of breastfed infants cannot be met by human milk alone. Hence, mothers are advised for supplementation of Vitamin D3.

4. To increase Vitamin D3 levels in elderly people because due to age and a long time spent indoors, their skin fails to synthesize Vitamin D3 efficiently.
5. To improve levels of Vitamin D3 in people with fat malabsorption whose intestine fails to absorb fat from the diet, thereby reducing the absorption of Vitamin D3 which needs dietary fat to get used by the body.

Why Do You Need Calcium & Vitamin D Supplements?
Your body cannot produce calcium on its own, so you have to rely on diet and supplements to meet your calcium needs. A lack of calcium could lead to a condition called rickets in children and osteomalacia or osteoporosis in later life. The symptoms of calcium deficiency include: 
Weak nails that break easily
Dry and rough hair
Dry and scaly skin
Muscle cramps
Forgetfulness (in severe cases)
Confusion (in severe cases)
Feeling sad (in severe cases)
Hallucinations (seeing, hearing, smelling, or feeling things that don’t exist)
Vitamin D is a fat-soluble vitamin that is naturally present in very few foods but is available as a dietary supplement. Vitamin D supplements are available in two forms: Vitamin D2 (“ergocalciferol” or pre-vitamin D) and Vitamin D3 (“cholecalciferol”). While Vitamin D2 is produced in plants and fungi, Vitamin D3 is produced in animals, including humans. Vitamin D3 deficiency is said to be associated with: 
Difficulty in making decisions in old age
Increased chances of severe asthma in children
Increased risk of death from heart diseases and cancers
Increased risk of osteoporosis (weak and brittle bones)
Increased risk of osteomalacia (softening of the bones)
Increases risk of rickets (a condition in which the mineralization of the bone tissue does not occur properly which can lead to bone softening and occurrence of bone deformities)
