My doctor recommended this vitamin D for me, very affordable price and it lasts for long

We don't understand why so many people (Medical Doctors included) continue to allege Vitamin D3 is toxic. Though D3 is not toxic, D2 [D(ERGO)] can be toxic (or is synthesized with dyes that can be toxic). This form of vitamin D3 is water-miscible; respectively, the body only absorbs and distributes what it needs; any excess is discharged. Though D2 can be harmful to kidneys; D3 promotes healthy kidney function. The benefits of vitamin D3 (and its lack of toxicity) has been well researched and reported with thousands of articles; not the least of which is the whitepaper written by: Dr. J. Joseph Prendergast, MD; titled: "Vitamin D3 Spray Whitepaper". The article is well written in layman's terms.Knowledgeable Health care practitioners wisely recommend that when supplementing a diet with D3 and K2 you should never take calcium supplements; just eat a normal healthy diet. In fact, for those that may experience pain in their extremities after taking large doses of D3, the culprit is not likely the D3; rather, they are most likely suplimenting calcium (which should never be done) it is actually hard not to get sufficient calcium if you have enough D3 and K2 (MK7).The body will produce 10,000 to 40,000 IU of D3 in 20 min of direct sun exposure (no more than that is recommended without sunscreen) after 20 min. the body reaches equilibrium; or, runs out of available cholesterol (which the body uses to naturally produce D3). The body can naturally produce 30,000 to 60,000 IU of D3 daily if two to three 10–20 min. periods (maximum of 20 min./period of exposure) sun exposure are evenly spread out across the day. If the body will naturally produce that much D3 in a day, how can it be harmful to take that much of a natural supplement of D3?I learned about D3 because my MD prescribed daily doses of 50,000 IU of D3 (I take 1-Bio-Tech D3-50 50,000 IU), 700 mcg of K2 (I take 7-NOW Foods Vitamin K-2,100mcg)(K2 is a necessary D3 companion vitamin for proper assimilation of D3) and 20,000 IU of Vitamin A (I take 2-Solgar Vitamin A 10,000 IU)to fight a melanoma that developed on my ear lobe. That treatment is going quite well. Canada reported running a test with some of their school's children wherein they gave students a massive dose of 500,000 IU D3 at the beginning of the school year for each year for five years (the reported results were incredible).Again, all too often medical doctors treat D1, D2 and D3 as if they were the same thing, having the same effect. They are not the same and they do not have the same effect. D and D2 can be toxic; however, it makes no sense that D3 could possibly be. Just as there is a distinctive difference between vitamin D [ERGO] and vitamin D3, there is a significant difference between vitamin K1 and vitamin K2; K1 (usually synthetic) can interfere with high blood pressure medication treatments K2 does not (we only use the natural form MK-7 "menaquinone"; for example: NOW Foods Vitamin K-2,100mcg, 100 Vcaps).The bottom line: people need to remember that medical doctors rarely get more that an introductory class in health in their normal training (if that); respectively, they are not generally trained in basic nutrition and/or health. Respectively, they are not generally the best source for learning about such matters. However, it is important to learn first, all you can about any nutritional claims from any source; especially if the source is promoting their own product. First, learn about the product, nutrient or supplement before taking anything; and, whenever possible use natural sources. In this case the best source for vitamin D3 is the sun. However, today it is -9°F outside; so, I am going to get my daily dose of 50,000 IU Vitamin D3 and 700 mcg Vitamin K2 from supplements.

This D3 was recommended by a physician for increased immunity. It’s easy to swallow. We have taken it for over 5 years and haven’t been sick since we’ve taken it .

My doctor is no longer carrying this item in her office and is having patients order on line. Easy to order and the item came quickly and with care from the delivery driver. This product is great, you take once a week and is a great value financially.

My Vit D levels were super low a couple years ago (who knew!). I was shocked when my doctor told me and I did a lot of reading and learned how important it is to keep Vit D levels normal. My doctor started me on "Stoss" therapy, which is one dose of 50,000 iu Vit D per week for 12 to 16 weeks. Vit D3 is really what one should take and NOT the prescription Vit D2 formula. So I ordered this product immediately and did not take the prescription Vit D my doctor wrote. Sometimes doctors do not know all they should! Anyway, blood retested after 16 weeks and my levels were normal, probably for the first time in years.I then read about a maintenance dosage of 1 pill (50,000 iu) every TWO weeks once normal levels have been achieved from the Stoss regimen, and that's exactly what I'm doing. My Vit D levels are maintained in the normal range, so I will keep this dosage going forever, unless something in my bloodwork changes. It's very important to get your Vit D levels tested at least a couple times a year. I get a battery of blood tests done every 4 months since I have other health issues to manage.This every other week dosage of 1 50K iu pill regimen works for me and is convenient. I have a reminder set in smartphone calender so I get pinged when the day arrives to take a dose. I take the pill with a meal, as recommended. No side effects whatsoever. Easy peasy. Oh and the size of the pill is really small. I thought I'd have to take a horsepill size capsule, but it's tiny, considering the amount of Vit D3 you're taking. Win!

Blood tests showed me low on Vitamin D. The doctor said even in sunny Florida most people come up low on D. I like this because it's only taken once a week. The main consequence of vitamin D toxicity is a buildup of calcium in your blood (hypercalcemia), which can cause poor appetite, nausea and vomiting. Weakness, frequent urination and kidney problems also may occur. I like the once a week dosage so I don't get too much. I never feel anything from vitamins. I'm low on Magnesium too and found a powder to mix in water, but don't feel any difference with that either. I'll see what the blood tests show next time. This is a good product from my research at a reasonable price.

What I had been looking for since insurance would not pay for it. Could not fine in store for right quantity dosage. Order and receive from you in 2 days. Thanks
