Nutrition and Supplements Vitamins and minerals Doctor's Best Vitamin D3 5000 Iu Softgels 360 What is Doctor & Best Vitamin D3? Doctor & Best Vitamin D3 is compatible with healthy bone density and structure, as it is required for optimal calcium absorption. More than that, this nutrient enhances and regulates immune function, supports optimal cardiovascular function and improves cellular function. It is made from D3, the natural form of vitamin D. Research shows that supplemental vitamin D3 (cholecalciferol) is significantly more efficient in converting to active vitamin D in the body than vitamin D2 (ergocalciferol). This makes vitamin D3 the preferred complementary form of this nutrient. Vitamin D deficiency is prevalent with more than 75% of Americans deficient in this nutrient. People living in the northern half of the United States are at increased risk of being deficient in vitamin D due to lack of sunlight. How does it work? Vitamin D from dietary intake or sun exposure requires two activation steps in the body. The first activation occurs in the liver, while the second activation occurs in the kidneys, allowing regulation of calcium metabolism. Vitamin D receptors are present throughout the body, in tissues such as skin, cartilage, heart, prostate, bones and intestines, so the second step of activation also takes place in local tissues.

Great quality, small and easy to swallow gel capsules with zero taste. Essential immune booster and I take it with Calcium for bone health. I notice my skin and nails improve, I have more energy and am more alert. Recommended by my Rheumatologist thrive iHerb and I have been taking them for many years. I don't absorb Vitamin D and end up deficient. I can't be sure, but I haven't had a cold or flu since taking high strength 5000iu Vitamin D3 dosage and my blood levels are perfect whilst taking them. Only one suggestion, a moisture absorption packet in the capsules, as they do stick together and need a good bash to separate them.

After complete thyroidectomy my Calcium and Vitamin D levels dropped drastically so endocrinologist suggested I should take some Vit D supplement to help raise the level of Ca. I've changed several supplements with no help until I tried Dr. Best's. It helped me increase the level of vit. D very fast (from 30 to 95 in a few weeks, now I keep it around 150). I highly recommend it! The pills are easy to swallow. It supports an immune system, if you take 5000IU daily, this container can lasts almost 2 years (I am recommended by my doctor to take 10.000IU daily, so it is my one-year supply). Always advice with your physician before you take some supplements.

Vitamin D plays a number of important roles in our body, the main one being its role in calcium metabolism and bone formation. This vitamin ensures, for example, that our intestine absorbs a greater amount of calcium and that our kidneys increase the reabsorption of this mineral, thus providing stronger bones. Unlike other known vitamins, vitamin D is not primarily acquired through food. The main source of this nutrient is its synthesis in the skin, which depends on ultraviolet B radiation. This radiation reaches our skin and transforms 7-dehydrocholesterol (cutaneous precursor of vitamin D) into pre-vitamin D3 and later into vitamin D3. It enters the bloodstream and travels to the liver and kidney, where it undergoes changes that make it active. When we talk about ...

It enters the bloodstream and travels to the liver and kidney, where it undergoes changes that make it active. When we talk about food, vitamin D sources are limited. It can be found in fatty fish, eggs and dairy products. It is worth noting that the diet is responsible for only 20% of our needs for this vitamin. Since a large part of its production is dependent on solar radiation, it became known as the “sunshine vitamin”. I am taking this supplement along with calcium & magnesium and K2. Because according to studies, these supplements together potentiate each other. If you think my review helped you click yes!
i am in my late 50ish and suffers from both mental and physical health. I work indoor most of the time in sunny Singapore (my little red-dot country and barely make contact with the FREE sunshine vitamin unless I am out to grab my meals (mostly ultra-processed & processed foods). After I put myself on the daily dose 600 I (tablet form) as recommended based on my age group it did not work after several weeks of use. I went on to read up extensively on the this hormone vitamin D benefits on our bone andblood health benefits. Upon reviewing the various brands, I opt to settle for NOW brand for it's dosage of 5000 IU in gel capsules form of D3 upon reading up on the possible causes of vitamin D deficiency.

Have been taking these Soft-gels since at least 2017, to good effect:I get very-little sunshine, practically no exposure at all,...Yet, with using this product - my Vitamin D count is ideal - bang in the middle of the normal-range - every time I get my VIT. D (DH-25) Blood-test results (every ~ 6 months), so Obviously this supplement works.No side-effects whatsoever. only caveat - As it contains nearly an entire year's supply - better to store it in the fridge - to prevent the Gelatin-soft-gels from partially-melting / leaking / becoming stickyAll in all - Highly recommended !
I bought these, and I must admit I feel the difference. However, I did a lot of research and found out that you need Vitamin D literally for everything. It is the most important vitamin besides potassium in your body. If you are low on Vitamin d, everything else in your body will suffer.This brand is really good, instead of using sunflower oil, they use olive oil. Very good brand, would recommend, the price-capsule ratio is very good.By the way, Vitamin d helps with vein health, blood flow, bone strenghtening, improving vision, reducing inflammation in your stomach and everywhere else. Basically, it is for everything!
My blood work said I was deficeint in Vitamin D. Since I started supplementing four weeks ago I am now sleeping and the hot flashes have been cut in half.Vit. D(3) is not a vitamin but a hormone. There are 4 ways to get vitamin (hormone) d3:#1 sun, #2 veggies, #3 fish oils like salmon, codliver, sardines #4 made from lanolin, which includes sprays, liquids, lotions, pills and mouse poison.One must be very careful taking d3 as it stays in the liver for 3 months, causes the blood to thin, and allows the calcium to get into the blood stream causing clogged arteries, calcium to deposit anywhere it wishes. Look it up.Vitamin D3 (cholecalciferol) has a few health benefits, including helping the body absorb calcium. Foods such as fish, beef liver, eggs, and cheese ...
