Much has been written about the Benefits of Vitamin D3. Therefore I will not go very deep here. I will say most adults living in the North or those who don't spend much time outside need to supplement. Certain medications will lower you D levels as well. Vit D is a HORMONE and not a vitamin. Therefore you want just the right levels in your body. Not too much and not too little. This is critical to understand so I always tell people to have your doctor test for your levels every year. Don't go by the lab range alone and feel you are ok. Most labs have a lower limit that is too low. Most progressively thinking doctors agree that you should be between 50-100 ng/ml on a standard 25-OH Vitamin D test. By maintaining this level you will be helped in many areas of your overall health. i.e. Immunity, bone health, cognition and much more. This is a good product in general and great when iHerb has it on special and you can get it for free or for a $1. Don't miss out when it is on special. I don't know why they call it EXTRA strength when it is only 1,000mg. That is a low to average dose for most adults. Take you vitamin D with some fat for better absorption. A recent study showed it is best absorbed with your largest meal of the day. I don't use this product typically. There is another brand in a liquid form which I feel is better absorbed and a better overall deal. If you go to my iHerb web page by clicking on my blue handle above you will see my recommended vitamin D as well as many other value added reviews. If you found this helpful kindly click on the "YES" button. Peace and good health!

This contains stearic acid, croscarmellose sodium, silicon dioxide, magnesium stearate. Who on earth would take that for their health? Calcium should not be obtained from Calcium Carbonate, which is chalk. This type of calcium can block arteries. So do not buy this look for a better product which contains D3, K2 & if possible Magnesium. This was free so i did not purchase it & will be binned.

There's magnesium stearate added to these tablets.Also,most brands have a NON GMO declaration on D vitamins but this one doesn't.I would recommend you to get D vitamins in gel caps since they don't have any fillers.Healthy Origins has NON GMO sign on their caps so I think I will try those next time.

If there's only one supplement you're taking for your health and your diet is decent, it should probably be Vitamin D. I highly recommend taking Vitamin D instead of a multivitamin most of the time. The standard supplement is Vitamin D3, otherwise known as cholecalciferol. Vitamin D3 tends to be better absorbed than other forms of Vitamin D. Vitamin D is an essential vitamin known as the sunlight vitamin, due to synthesis occurring in the skin from the sun's radiation. It has a multitude of benefits to the body including supporting bone structure, mood state, and is generally seen as healthy and anticancer. The RDA for vitamin D is currently set at 400-800IU/day, but this is likely too low for adults. The safe upper limit in the United States is currently defined as 2,000IU/day, and in Canada it's 4,000IU/day. However, research suggests that the true safe upper limit is 10,000IU/day. Supplemental vitamin D is implicated in wide-ranging benefits, such as increasing cognition, immune health, bone health, and well-being; reducing the risks of cancer, heart disease, diabetes, and multiple sclerosis; and increasing testosterone levels in deficient populations. This product by 21st Century Health Care offers a cost-effective supplement for the benefits mentioned above. Taking everything into account, I highly recommend this high quality product. I hope you'll find my review helpful to you. I am a strong advocate on scientific medical research and evidence-based information, and constantly want to differentiate between marketing hyperbole and real world effects.

This supplement contains magnesium stearate, stearic acid, croscarmellose sodium, and silicon dioxide. Magnesium stearate is a lubricant used to prevent capsules from sticking to each other or the equipment being used, which creates a biofilm in the body and blocks the body from absorbing the necessary nutrients. Stearic acid is most likely to be animal derived (since it's not specified that it's plant derived) and may be neurotoxic and carcinogenic. Croscarmellose sodium is a commonly used matrix to deliver drugs to the intestines. Known for its sponge-like ability, it can expand up to 20 times its original size by soaking up fluids in the body, but may create an intestinal blockage. This ingredient can also absorb moisture from the air, which could cause the drug to be released in the stomach instead of the intestines, so that you don't get the correct dose. It also pro motes the growth of harmful intestinal bacteria and can exacerbate the symptoms of Crohn’s disease, irritable bowel syndrome and celiac disease. Silicon dioxide can lower blood sugar and is dangerous for people suffering from diabetes, can lead to thiamin (vitamin B1) deficiency and dehydration and dangerously low pota ssium levels, if taken with diuretics. Definitely not a vitamin D supplement I would recommend.
