I have waited until I had my Vitamin D level re-tested as I wanted to comment on the efficacy of the product as well as the excellent service from iHerb. When I started taking these softgels, my level was 18 ng/ml and after taking one a day for 6 weeks, it is now 72 ng/ml - so I can safely say that they have worked for me! It is great to be able to buy 10,000IU capsules as they aren't available in the UK, and the price is excellent. If you are ordering from the UK and are in a hurry to receive your order, it is better to pay the extra for DHL shipping, as the ordinary post took 10 days, even though iHerb shipped the order the day I placed it.

As human beings, our lifestyles have changed from that of barely-clothed, nearly naked hunter-gatherers spending most of our daylight time outdoors, to fully clothed, smothered in sunscreen, and spending very little time outdoors. This effectively stops our skin from assimilating Vit D from sunlight, which is our primary source of this pro-hormone. No wonder we have so many health epidemics and pandemics, particularly the degenerative diseases and cancers. The immune stimulating effects of D3 - and it MUST be the "3" form, which is cholecalciferol, from animal sources, and not ergocalciferol, which is D2, and from plant sources - are monumental. Be wary of studies that claim vit D supplementation has no effect on bone density or other issues - check that they have used a decent amount (a lot of studies only use 400 or 800IU, and of courser that won't show any beneficial effect because it isn't enough), and that the form was D3 and not D2. Check out potential toxicity issues for yourself. Some people who say they tried vit D and got bone spurs and other calcium deposition problems as a result experienced that because they did not observe some simple facts: Vit D needs Vit K to direct the calcium into the bones - without that process happening, the calcium will OF COURSE get dumped willy-nilly by the body. You can think of Vit K like a mini-bus, picking up the workers and driving then to the job-site. Unless K is there to pick the calcium up, the calcium just wanders around until it lands somewhere and stays there. This is also why some people get kidney stones on high dose D. Other bone factors have to be considered too - estrogen and progesterone are critical to bone health - they produce osteoclasts, which clear away old bone cells, and osteoblasts, which build new bone. You cannot build new bone until the dead stuff has been cleared away, in the same way that you couldn't build a safe new building directly on top of a derelict building with wonky foundations. Other minerals are also important. The calcium:magnesium ratio is especially crucial to get right, and this is going to vary from person to person, with some health conditions benefitting from way more magnesium than calcium. An easy way to check that you are taking enough magnesium is to observe the standard natural medicine protocol of observing any sudden change in stool texture. When you have taken as much mag as your body can use that day, you experience what I can "torpedo poos", which is to say that they pop out quite fast, and are very smooth (not the ideal stool as it indicates food has passed through too fast for optimal absorbtion, but a good way to check you mag requirement). Silica is very important too, because part of bone health is flexibility of the tissue. According to some studies and claims, only 10% of bone structure is actually calcium, the rest is collagen, which is the same springy stuff that gives our skin (and blood vessels and other connective tissues like cartilage, tendon, etc etc) its elasticity. Silica, it is claimed, is as important as Vit K in directing calcium away from soft tissues and into bone. The idea is that the bones are where the body is designed to store calcium so that it can be pulled out of the bones and into the blood as needed - blood levels are kept within very very narrow margins, and any deviation from these margins disrupts health in a major way. So, according to something I read on Eidon's website, only 10% of bone is made of calcium, but bone is the storage depot for calcium. And calcium needs silica as well as Vit D3, Vit K (the MK7 lasts twice as long in the body than the ordinary K2), phosphorous (very plentiful in diet and prob no need to supplement), magnesium, estrogen (definitely in women, I haven't checked to see about men, but presumably they also have the same mechanism of action for osteoblasts and osteoclasts, and contrary to popular belief, men DO produce estrogen, just like women produce testosterone, we each just produce the others major sex hormone in smaller amounts than the opposite sex does), progesterone...........I know some people without osteoporosis and otherwise healthy (I have osteoporosis, breast cancer, fibromyalgia, low adrenal and thyroid function, and other issues) have successfully added high dose D 10k IU/day along with K2, and haven't needed to address other more extensive bone health issues, but please be aware of all these different factors before leaping in without thinking about adding silica and the others. Oh, before I forget, another thing to investigate is Vitamin A, currently a bit out of favour, but think about it - in cod liver oil, which occurs naturally, and indeed used to be prescribed by the government for pregnant women in the UK, and was also prescribed by the government here in war time when we spent a lot of time underground to escape the bombs, levels of Vit A are HIGHER than Vit D. Maybe once D levels have been brought up to optimal status, at which point you can determine your ongoing maintainance dose (which will be lower than you repletion dose), Vit A then needs to be adjusted according to this principle. M Aziz's book is a brilliant source of info, and contains a huge amount of medical references that you can go and check for yourself. It is his personal account of helping himself and his family with high dose D3. He has been taking 10K-12500 IU a day for the past 6-8 years, with nothing but beneficial effects. His bone density has increased. He takes no supplemental calcium or magnesium or progesterone or estrogen, nor silica, just MK7 K2. Also, it is obviously vital to get our GP onside and to have your D levels checked before and during supplementation. Just use you own knowledge of what the test SHOULD say in order for you to be optimal, rather than what the reference ranges on the tests say - they differ wildly from lab to lab, hospital to hospital, so draw your own conclusions. Hope this helps - read M Aziz's book it's a really exciting eye-opener. Currently an e book from the biggest online bookseller.

As a nurse we didn't learn much about vitamin d in school and I have never had a doctor check it. So after seeing patient after patient with no vit d I checked mine and the level was 11. I live in the south, wear no sunscreen, and I'm outside daily and I had no vit d. After this product my level was 80, I no longer felt tired or yawned in the afternoon, and I FELT AMAZING. I took a rx dose which was 50,000 units 3 times a week for 3 weeks then once weekly for 3 weeks. I then had enough to take one daily for months all for less money than the rx d2 would have cost. I recently ordered my 2nd bottle and the package was stolen. I didn't even have to speak with iherb they sent me a new package within a week, but I could already feel the fatigue coming back. So you definitely feel it. It also helps prevent cancer, heart disease,osteoperosis...which I had osteopenia few years ago(i am in my 20's) this years check was normal and thats the only thing I have changed.

Everyone should be taking this everyday. Forget what the current RDA is. Vitamin D (actual not a vitamin as the body makes it) is absolutely essential in literally thousands of processes in the human body. In this day of suncream and skin cancer, you just can't get enough from the sun. This 10,000 IU is called Clinical Strength, but don't let that fool you. This is about the basic needed to keep you healthy. Besides D is stored in the liver and useable later... and is non-toxic. Trust me... you may be getting enough D to keep you from getting rickets, but unless you are taking 5-15,000 IU per day you are not getting the full benefit of this wonderous proto-hormone.

I was waiting to respond to see how my D levels tested. I had been at 16, a year later at 20 on 2K IU daily supplement and feeling horrible. I have been taking this since then and my last test two weeks ago I am at 60.
Muito bom - very good.

Best Value Product On The Market

Easily the only Vitamin D worth buying! Small, easy-to-swallow capsules, in a compact tub, arrived very soon after ordering (well done iHerb!). The lowest cost per IU of Vitamin D I have found anywhere. Why anyone would buy a lower dose (unless you have small children) is beyond me. Your skin can make 10000 IUs in <20 mins in the summer! Vitamin D causes production of antimicrobial peptides; good article on them here: www.hardydiagnostics.com/articles/Antimicrobial-Peptides.pdf

I've always had difficulty absorbing Vitamin D, and I have to take 7,000 IU weekly to get it to stabilize at regular levels. In Brazil, a pack with 4 pills with 7,000 IU costs around USD 8,90 (same formula - Cholecalciferol). I bought this product for USD 21 with shipping. After paying import taxes it summed up to USD 33,60. That is, I bought 360 pills for the price of 15. A deal can't get better than that! Some brazilians complain that they didn't receive the product, however customs through USPS is extremely slow. I've waited 25 days just to get customs clearance, and that's considered fast.
