Do calcium tablets of vitamin D3 contain hormones?

Vitamin D3 is a hormone in its own right.

Vitamin D is also considered a steroid hormone. The main active ingredient in calcium tablets is CA.

The importance of calcium in ensuring strong bones, teeth and preventing osteoporosis. Once calcium is insufficient, it will easily cause tooth decay, osteoporosis and osteomalacia, and young children are prone to stunting, low back pain and knee pain.

The most important members of the vitamin D family are VD2 (ergocalciferol) and VD3 (cholecalciferol). Vitamin D is a derivative of different provitamin D after ultraviolet irradiation. Plants do not contain vitamin D, but provitamin D is present in both animals and plants.

Vitamin D is a fat-soluble vitamin with five compounds, and vitamin D2 and vitamin D3 are more closely related to health. They have the following three properties: they are found in some natural foods; The human body stores 7-dehydrocholesterol produced from cholesterol under the skin, which can be converted into vitamin D3 when exposed to ultraviolet light.

Proper sunbathing is sufficient to meet the body's need for vitamin D.

No, but it can promote calcium absorption, so it is usually taken together! Some calcium tablets contain vitamin D!

At present, calcium tablets on the market are basically supplemented with vitamin D at the same time to promote absorption.

The role and function of vitamin D3 and ***, we will include vitamin D when we take vitamins, and vitamin D3 is one of the vitamin D family. Many people may not know much about vitamin D3, if you want to know the role and function of vitamin D3, let's take a look.

Pharmacological efficacy and action

It is a fat-soluble vitamin, promotes calcemia, inhibits its excretion, promotes the absorption and storage of calcium and phosphorus in the intestine, improves the content of blood calcium and blood phosphorus, cooperates with parathyroid hormone and calcitonin, regulates the normal concentration of calcium and phosphorus in plasma, enhances the reabsorption of calcium and phosphorus ions in the renal tubules, makes calcium settle in the new bone formation site, promotes the normal calcification of bones, and promotes the calcification of bone matrix. This product is catalyzed by the 25-hydroxylase system to generate calcifediol (25-OHD) in cellular microsomes, and catalyzed by the 1-hydroxylase system of renal proximal convoluted tubular cells to generate biologically active calcitriol [1-25(OH)2D3. It is mainly used for the prevention and treatment of vitamin D deficiency caused by various reasons, including rickets, osteomalacia, infantile tetany, hypoparathyroidism, etc.

This product is absorbed in the small intestine, which is more rapid and complete than vitamin D2 absorption, and bile assists its intestinal absorption; Metabolism and activation first pass through the liver, followed by the kidney, and generate the most active calcitriol, which is partially degraded in the kidney.

It is mainly excreted by bile and feces, and a small amount is excreted in urine or can be secreted from breast milk. T1 2 is 19 48h.

Precautions, *** and hazards

1. Patients with hypercalcemia, hypervitaminosis D, hyperphosphatemia and renal rickets are prohibited. Patients with coronary heart disease, arteriosclerosis, cardiac insufficiency and hypercalcemia and hypercholesterolemia should be used with caution, and patients with hyperphosphatemia and renal insufficiency, infants and pregnant women should use with caution.

2. Long-term use of large doses or short-term overdose can cause toxic reactions, and chronic poisoning caused by high calcemia can cause dizziness, vomiting, constipation or diarrhea, abdominal pain, muscle weakness, bone pain, etc., and can lead to systemic vascular calcification, renal bone deposition, soft tissue calcification, hypertension and even kidney failure, and the growth and development of children should be stopped.

3. Blood calcium and blood phosphorus concentrations should be monitored during medication.

4. The combination of calcitonin and vitamin D3 can offset the efficacy of the former on hypercalcemia.

5. Magnesium-containing antacids are used together with vitamin D23, especially in patients with chronic renal failure, which can cause hypermagnesemia.

6. Calcium should be taken before and during medication.

7. The combination of digitalis drugs and this product is prone to arrhythmia.

8. For the rest, please refer to vitamin D2.

9. 1mg of this product = 40,000u.

It is best not to eat both at the same time, it is best to take a multivitamin about 30 minutes after breakfast, and take calcium tablets before going to bed at night, so as to help absorption. The best time to take calcium is every day before bedtime. In a three-day-a-day diet, the human body can consume 300 mg to 400 mg or more of calcium from food, and when the body excretes calcium from the urine through the calcium regulation mechanism, the blood can be replenished from food at any time to maintain blood calcium levels.

At night, the body no longer eats, and urine is formed as usual, and a part of the calcium in the blood continues to enter the urine, so in order to maintain a normal blood calcium level, the body has to use the calcium store, which is the calcium in the bones. Calcium supplementation before going to bed can provide a calcium source for this calcium regulation at night, blocking the use of bone calcium in the body, and calcium also has a sedative effect, which can help sleep. You really don't have to be worthy of everyone, but you have to be worthy of yourself.

You don't have to be afraid to fail anyone, but don't let yourself down.

Vitamin D3 can promote intestinal absorption of calcium and phosphorus, promote their deposition in bones, facilitate bone growth, and maintain the balance of blood calcium and phosphorus.

Analysis:

Vitamin D3 can be converted into calcium.

Guidance: There is no need to take calcium tablets when taking vitamin D3 to avoid waste.

Vitamin D3 promotes calcium absorption, and there is no maintenance when taken at the same time, but if the body is not deficient, it is harmful to take it at the same time.

Excessive intake of calcium may interfere with the absorption and utilization of other trace elements in the human body, and may also lead to an increased risk of kidney stone disease. Eat normally and do not need calcium supplementation.

The human body stores 7-dehydrocholesterol produced from cholesterol under the skin, which can be converted into vitamin D3 when exposed to ultraviolet light. Proper sunbathing is sufficient to meet the body's need for vitamin D.

Expose 30 cm of hands and feet every day and bask in the sun for 30 minutes to effectively prevent vitamin D deficiency.

Vitamin D overdose: Some scholars believe that long-term intake of 25 g of vitamin D per day can cause toxicity, which may include some people who are more sensitive to vitamin D, but long-term intake of 125 g of vitamin D per day can certainly cause toxicity. Symptoms of poisoning are abnormal thirst, eye irritation, itching, anorexia, drowsiness, vomiting, diarrhea, frequent urination, and abnormal precipitation of calcium in the walls of blood vessels, liver, lungs, kidneys, stomach, joint pain and diffuse bone demineralization.

The tolerable maximum intake of vitamin D in China is 20 g.

Therefore, it is not recommended to take it orally or injectably, and the safest thing is to bask in the sun.
