Doctor's Best - Vitamin D3 1000 IU - 180 Softgels
Doctor’s Best Vitamin D3 supports 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 enhances cellular function. It is made of D3‚ the naturally occurring form of vitamin D. Research shows that supplemental vitamin D3 (cholecalciferol) is significantly more efficient at converting to active vitamin D in the body than vitamin D2 (ergocalciferol). This makes vitamin D3 the preferred supplemental form of this nutrient. Vitamin D deficiency is prevalent with more than 75% of Americans deficient in this nutrient. People who live in the northern half of the United States are at a greater risk of being Vitamin D deficient due to a lack of sunlight.

You can have too much Vitamin D in your bloodstream! Over 50 -60 ng/mL can actually cause trouble (ask your doctor to be sure.)Two people I know were recently found to have levels of over 100 ng/mL in the past couple of days, and told not to take any Vitamin D supplement for 30 days.This supplement contains 125% of the RDA. That's the amount in my calcium supplement. My Vitamin D level is on the high end of normal.

Taking vitamin D3 soft gels have made an improvement in my vitamin D levels as measured by my doctor via blood work. I’ve had an ongoing problem with low vitamin D3 for decades and was taking another 5000IU gel was keeping me in the middle of the range on my blood tests.These are doing the exact same for me. The gels in this brand look virtually identical to the ones I took before. These D3 soft gels are keeping me at the middle of the range for Vitamin D3 blood level. With these I get about twice the number of gels for about the same price as my previous brand.

I appreciate the value of getting twice as many for the same price, but best of all they work well for me and I'm very pleased and giving them 5 stars. Like if you find this helpful.

There are so many health benefits associated with Vitamin D. It's very important to get adequate amounts. Easy to swallow and great value. I bought this because there is NO Soy OIL in it. I take one 1000 iu soft gel at breakfast and another one at dinner. I noticed within the week that I had more stamina and I am more cheerful. I'm not surprised since D3 works in hundreds of enzyme systems in the body.

Great value for money. Vitamin D3 is so important in this time where we use a lot of SPF and can't absorb enough Vitamin D from sun exposure or through restricted diets. My hair was falling out in handfuls and after taking Vitamin D everyday for a couple weeks my hair stopped falling out and has regained its thickness over time (I'm female). It has also helped massively with psoriasis- I apply it topically in some natural body oil or lotion (alternating some days between Vitamin d and vitamin c).
Doctor’s Best is a great company, and this is just the right amount of vitamin D3 if you generally have good levels but might occasionally (or seasonally) need a little boost. Affordable high quality d3 with no unnecessary additives and super easy to take because they are so little. Contain just a bit of oil to aid in absorption. Highly recommend!
I chose Doctor's Best Vitamin D because it was among the few (if not only) brands that used extra virgin olive oil instead of soy. The pill is small and easy to swallow, and I derive a certain amount of worry-free confidence because it uses virgin olive oil in place of something more questionable. I like the 1000 IU size because I can take one in the morning and another after dinner and not worry about taking too much, which became a problem with supplements with higher dosages. I also believe that 180 soft gels for $4.74 is a good deal for a product of this quality.
Prophylactic dose of vitamin D or children's. The level of vitamin D can not be raised, of course, because you need to drink at least 2000 IU, but it can support. The brand is good, my daughter drinks two capsules after breakfast. Be sure, with butter or healthy fats should be. Capsules are small, it is convenient to drink. Like if my review helped.
