ideal for winter, autumn, spring. Vitamin D3. About Vitamin D3. D 3. Vitamin D. Not For Uncontrolled Reception. Convenient for baby. Good firm, normal dosage. recommend. Vitamin D3

a very important vitamin for the body. Unfortunately, with the sun we do not get the full dose of vitamin D3. The daily dose of vitamin 400-600ME, and the maximum dose of 2500 ME, so these vitamins are average in dosage and chic especially in winter If you do not mind and liked the feedback Press YES

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.

Why add glycerin to vitamins D3? It also destroys the walls of blood vessels, does not allow liquid to be excreted, leads to edema, renders the kidneys unusable. Why does the manufacturer do this, do we cure another one? So it is.

I drank 3 months, for the prevention of 1000 IU, I continue further, I hope that it will be useful.

It is also believed that this vitamin helps to prevent cancer (especially “female”)

Great vitamin

I want ask about source of gelatin it’s beef or pork!?
What is the olive oil for? Why is it part of it
why is this product ranking #1 in niacin?
does witamin d must be taken with oil?
is this vegan?
Has anyone tried to taste the oil inside the capsules? Another brand of Vit D3 taste very rancid? How about this one?
Do these softgels have any smell? I opened the bottle yesterday and nothing was strange, but today I noticed a kind of fishy smell. The expiration date is far away. Is it still safe to take them?
Is this product halal? I mean the bovine And Is the gelatin not only the bovine !? Cause gelatin is mainly made with the skin of the pigs! Please reply fast as I already made my order and didn’t notice until now?!
Is this brand good?
Is this product free from gluten and fish?

The bottle I have is beef.
Vitamin D is a fat soluble vitamin, and latest studies show that monounsaturated fats (like those in olive oil) are associated with better Vitamin D absorbtion than powdered Vitamin D. The differences though are minuscule.
I think it’s just a digital mistake. D3 and B3(Niacin) has nothing to do with each other. Just a mistake. Regards.
No. The ingredients state that the capsule contains bovine gelatin.
Never tasted it. It is not meant for chewing, rather for swallowing. Almost all pills/medicines have bad/bitter taste when chewed instead of swallowed.
I’ve never experienced a smell with this product. I do take a lot of supplements at once, but would have noticed that.
It is not a problem! Thank you for attentiveness:)
Yes. Taking one per day raised my vitamin d levels on my bloodwork and the doctor.
Not manufactured with gluten or fish.
