    Hi OP, is it better to sit under the sun rather than having this tablet?


    If we subscribe and then cancel, can we still get "subscribe and save" deals later for the same product or other products?


    Cheers OP :)

        Gentle sun exposure can be good for people deficient in vitamin D.

        Most people in Australia with vitamin D deficiencies live in nursing homes or have dark skin. The former is often treated with supplements. The latter will not likely get skin cancer from moderate sun exposure.

    This only has 1000IU per tablet. $14.82, one a day will last you 13 months. Or you can buy the 5000IU per capsule version elsewhere, iherb has this one with 360 capsules for $17.56 with "Flat AU$5.86 shipping or Free for orders over AU$58.55", so that's $23.42. That will last you one a day for 12 months, but you get five times as much vitamin D, and 5000 IU of D3 seems to be the typical dose in America. If you are deficient in vitamin D then what are the chances that just 1000 IU will be enough, why not go for the mega 5000 IU dose. I see they have 10000 IU doses too.

      If you are deficient in vitamin D then what are the chances that just 1000 IU will be enough, why not go for the mega 5000 IU dose.

      Because that's called overdosing.

      "…the recommended daily adequate intake (AI) of vitamin D in Australia is 5 micrograms (200 IU) for children, adolescents and adults aged 19–50 years, 10 micrograms (400 IU) for adults aged 51–70 years, and 15 micrograms (600 IU) for adults over 70 years of age."


      My patients deficient in vitamin D come back to normal levels on 1000 units. Why then should they take 5000 units daily?

      Americans do a lot of things. They also die much earlier than us on average

        1000ui won't do anything. 5000ui a day minimum if you have a deficiency.

          Vit D has a 14 day half life meaning you don't have to take it daily either.

          I have 10000ui and I take them once every 7-12 days, no exact science. My levels are perfect.


            @Click_It: Yes thank you. My doctor has asked me to take 2 x 1000 IU tabs per day. As a true ozbargainer I have worked out that since the 5000 IU tabs cost only slightly more than 1000 IU I would be better of financially to buy the 5000 IU and take it every second day. Since they are D3 they have a longer half life.


              @Yola: For about $17 (maybe less) you can get 10,000 UI 360 gel tabs, take 1 ever 5 days to exactly meet your doctors recommendations and that's 72/year or 5 years supply. Though I personally wouldn't want a bottle lasting 5 years so I pay a little more for bottles of about 60. The 360 would be great if sharing with others though.

              This deal here will get you to 200 days and you're empty. There's no comparison.

              iHerb works best buying bulk to avoid shipping costs though so it may work, it may not. But 400 of these isn't a bargain IMO.

        Not if the person has tested as deficient. From the news article you posted -

        “In Australia, guidelines recommend vitamin D3supplementation at 25–50 micrograms (1000–2000 IU) per day for people with mild vitamin D deficiency.4

        For moderate to severe deficiency, vitamin D3supplementation is recommended at 75–125 micrograms (3000–5000 IU) per day for 6–12 weeks, or 1250 micrograms (50,000 IU) once a month for 3–6 months.4”

          How many OzBargainers do you think have moderate to severe vitamin D deficiency? That's really a conversation they should be having with their doctor rather than taking too much vitamin D on the advice of an anonymous internet person.


            @jazoom: It's easily tested by a doctor so you are absolutely right. Start there!

            Vitamin D levels respond very well to supplementation and/or sun for most people. I get good amounts of sun in the warmer months so I mostly take them through the colder months. If low you'll know, immune system takes a hit and you'll catch colds a lot easier. Asthma symptoms can be worse too. Great stuff Vitamin D. Does lots of things for the body.


        why shouldn't they take 5000 units daily if its just a few dollars more. Is there some kind of link between vitamin d3 and death?


          That's a great question and I don't have a solid answer for you. I prefer to practice conservative medicine. Even if we don't know currently of effects from taking more vitamin D than necessary that doesn't mean we won't ever find some.

          If a lower dose fixes the problem, I go with that. I practice this way with almost all medications. I think most doctors do.


          Death? No I don't think so. But it's your kidney that processes all this stuff so you run the risk of toxicity.

          Interestingly enough, the very thing that makes Vitamin D amazing (see my post above about half life and taking up to 10,000 IU) is also what makes it dangerous. That gradual build up also means it can take a long time to get the levels back down again.

          Because Vitamin D helps you absorb Calcium more efficiently, you can end up with calcium toxicity, does passing calcium stones sound fun? Now I could be wrong but I think at super high levels it will also begin to leech calcium from your bones too. It also messes with Vitamin K2 at extreme levels which is important to the body.

          If you ignore all these symptoms final destination is kidney failure. But death? You should survive.
