Now Foods, Vitamin D-3 High Potency, 2,000 IU, 240 Softgels Product Review

High dosage. Good product. Daily dosage to maintain 25OH. Everyone needs. Optimal dosage. Great Vitamin. It works great! The number of capsules is less. I don’t feel like catching a cold. Great vitamins.

The famous vitamin D3 – tens of thousands of articles have already been written about it, how it is useful and how much it is needed. The main factors you need to know about it: we cannot get vitamin D3 from food, the only way to saturate our body with this vitamin is to be in the sun. Unfortunately, today, due to our meager lifestyle in nature, and living in the northern latitudes of our planet, people do not physically receive the right amount of vitamin D3. Not only do we have half a year, it is gloomy and not sunny in the cold season, but also in the summer, good weather has recently become scarce. And in addition, people simply have no time to be in the sun, even in the summer, because of today’s high pace of life. Personally, I think that vitamin D3 should be taken from around the beginning of November to the end of February. Many will say “what are you, we don’t have enough of it in the summer and we need to drink it in the summer”, you can’t take one vitamin all year round so that different paid scientists do not say there in order to increase sales of supplements. The body itself must also produce this vitamin, after all, the body produces vitamin D3 in any case in the summer, but its greatest need is in the period that I wrote about above. What is most important to know about the benefits of vitamin D3 – regulating the balance of calcium, phosphorus and magnesium; regulates hormones; spreads elements throughout the body; promotes cells to divide properly; promotes the correct exchange of processes; supports vision. This is only an insignificant part of everything that this vitamin is needed for, the spectrum of benefits of vitamin D3 is huge. As for the dosage, the dosage should be adequate. I myself have witnessed how a person, due to a high dosage of vitamin D3, developed sand in his urine, the so-called oxalates, that is, organic salts. This is serious. A person may not know for weeks about his metabolic disorder until his urine turns red. I will share with you only my personal opinion on the correct dosage of vitamin D3, based on adequate statistics from scientists from different countries. Children under 12 years of age cannot even come close to this. For children from 12 to 18 years, the dosage should not exceed 400 IU / day. For adults, for prevention, the dosage should not exceed 1000 IU / day. For therapeutic purposes, everything is individual and everything is strictly according to the doctor’s recommendations.

I ordered 15 years for my son. He was given myopathy, but not hereditary, what caused the damage to muscle tissue is unknown. I think the Epstein-Barr virus is the culprit.

NOW has chosen a reasonable price-quality ratio. She stopped at a dosage of 2,000. They drank 2 times a day (morning and afternoon) after eating 1 capsule, that is, the daily norm is 4,000. The new analysis has not yet been retaken, but at the time of taking the drug there were slight improvements, the child was a bit more cheerful. Perhaps this is also due to the intake of L-carnitine 500 (3 p 1 cap. ) And Q10 – 30 mg all from NOW, and maybe their combined effect. At the moment, the child is sick more, the drug ended more than 1.5 months ago. This time I ordered NOW D3 at a dose of 5,000 + NOW multivitamins. I advise you to take D3 with food containing fats, it is better absorbed (for example, eggs, milk, cottage cheese, salad, seasoned with any vegetable oil, etc. ) And most importantly, you need to take it in the morning or at lunch. According to recent reports, D3 belongs to hormones and to some extent interferes with the normal production of Melatonin (the hormone responsible for sleep). So I do not recommend taking it in the evening, especially for people suffering from insomnia. If you find my review helpful, please give a like. Thanks.

Masthead family first aid kit! The GMP standard and one of the most popular manufacturers always guarantee the high quality of their dietary supplements.2000 ME is a low dosage, but I always have capsules with such contents – on trips to the south, I and my loved ones do not stop taking vitamin D, because we use protective creams, and the synthesis of this vitamin is known to occur only if the skin is exposed to the sun rays. I also add capsules with such a dosage to the usual 5000 IU during periods of completely sunless days, if due to employment I do not go to fresh air at all – all this affects the level of serum 25OH in the blood. But I try to control this indicator so as not to go over the dosage – otherwise the vitamin will become toxic.

I did an analysis for vitamin D, I drank first at 10,000, and now on an ongoing basis at 2,000. I drink in the morning, after a sandwich with butter or cottage cheese. Keep open packaging in the refrigerator and not more than 3 months.
