Calcitriol is the vitamin D precursor produced in the dermal capillaries that aid calcium absorption. Approximately 10 -15 minutes twice a week is necessary for vitamin D synthesis.

The precursor produced in the dermal capillary is 7-dehydrocholesterol, which is converted to vitamin D3 (cholecalciferol) in the skin upon exposure to ultraviolet B light. Vitamin D3 plays a crucial role in aiding calcium absorption in the intestine, which is essential for maintaining bone health and overall mineral balance in the body.

What controls the amount of calcium in the blood?
Parathyroid hormone (PTH) and calcitonin are key regulators of calcium levels in the blood. PTH increases calcium levels by stimulating the release of calcium from bones and promoting its absorption from the intestines and kidneys. In contrast, calcitonin decreases blood calcium levels by inhibiting calcium release from bones.
What gland increases blood calcium level stimulates calcium re-absorption and activates vitamin D?
The parathyroid gland is responsible for increasing blood calcium levels by stimulating calcium re-absorption in the kidneys and activating vitamin D, which helps in calcium absorption in the intestines.
Which mineral's absorption is affected by an excessive use of antacids?
Calcium absorption can be affected by excessive use of antacids, as antacids can reduce the acidity in the stomach needed for calcium absorption. This can lead to lower levels of calcium being absorbed by the body.
What is the site of calcium absorption?
Calcium is primarily absorbed in the small intestine, specifically in the duodenum and the jejunum. Absorption occurs through a combination of passive diffusion and active transport mechanisms. Factors such as vitamin D, pH levels, and the presence of other nutrients can influence calcium absorption.
Does parathyroid gland secretes calcitonin?
No, the parathyroid gland secretes parathyroid hormone (PTH), not calcitonin. PTH helps regulate calcium levels in the blood by stimulating the release of calcium from bones and increasing calcium absorption in the intestines and kidneys. Calcitonin is produced by the thyroid gland and helps regulate calcium levels by decreasing calcium release from bones.
What substance is produced in the skin that aids in calcium absorption in the body?
Ergosterol production stimulated by UV rays forms Vitamin D to make healthy bones. Bone needs and stores calcium phosphate in order for the bones to ossify. Vitamin D3 (aka cholecalciferol) is made in the skin from 7-dehydrocholesterol.
Which ingredient found in coffee and cola can decrease calcium absorption?
Caffeine: Caffeine has a small effect on calcium absorption. It can temporarily increase calcium excretion and may modestly decrease calcium absorption, an effect easily offset by increasing calcium consumption in the diet.
What enhances calcium absorption in GI tract?
Vitamin D is essential for enhancing calcium absorption in the GI tract. It helps regulate calcium levels in the body and promotes the absorption of calcium from the intestines into the bloodstream. Additionally, factors like adequate stomach acid levels and a diet rich in calcium-containing foods can also support calcium absorption.
The absorption of calcium increases during pregnancy because?
both high levels of the active form of vitamin D enhance calcium absorption and high levels of estrogen enhance calcium absorption are true
What is calcium as aminoate complex?
Calcium aminoate complex is a form of calcium supplement where calcium is chelated to amino acids for better absorption in the body. Chelation helps to protect the calcium from interacting with other compounds in the digestive system, allowing for increased effectiveness and bioavailability of calcium. This form of calcium supplement is often used to support bone health and overall calcium levels in the body.
What controls the amount of calcium in the blood?
Parathyroid hormone (PTH) and calcitonin are key regulators of calcium levels in the blood. PTH increases calcium levels by stimulating the release of calcium from bones and promoting its absorption from the intestines and kidneys. In contrast, calcitonin decreases blood calcium levels by inhibiting calcium release from bones.
Oxalates can inhibit the absorption of what?
calcium
Why does Calcium absorption decline in the elderly?
Calcium absorption can decline in the elderly due to reduced production of stomach acid, which is necessary for calcium absorption in the intestines. Additionally, age-related changes in the intestinal lining can affect calcium absorption. Lastly, decreased physical activity in the elderly can also contribute to lower calcium absorption.
Which mineral's absorption is affected by an excessive use of antacids?
Calcium absorption can be affected by excessive use of antacids, as antacids can reduce the acidity in the stomach needed for calcium absorption. This can lead to lower levels of calcium being absorbed by the body.
Does melanin help in calcium absorption?
No, melanin protects the skin from ultraviolet radiation. Vitamin D is synthesized in the skin and help with calcium absorption.
In what Vitamin d is important in the absorption and metabolism of?
Calcium
What facilitates absorption of calcium and phosphorus?
Vitamin D plays a crucial role in facilitating the absorption of calcium and phosphorus in the intestines. It enhances the production of proteins that are necessary for transporting these minerals into the bloodstream, where they can then be utilized by the body for various functions. Additionally, factors like adequate stomach acid levels and a healthy gut lining also support the absorption of calcium and phosphorus.
