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 .

Used this for years! Great product!

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.

I was prescribed this exact brand and dosage in the hospital. I found it cheaper on Amazon. Apparently it works because my blood work labs no longer show low levels

Delivery quick. Taste good. Easy to swallow.

My naturalopathic practitioner recommended this brand. She also suggested I take one tablet the first and 15th of each month. I do that and my D3 levels are never low.
