too weak @1000IU
1000 IU is a joke.
you need 10,000 IU minimum a day of Vitamin D, it actually makes a real difference. If, you go supplements makes sure you have a combination supplement with 10,000 IU D3, K2, and magnesium!! with out magnesium you will not be able to process D3 very well. So make sure you have enough magnesium with your D3 as well.
Got a source for this? A lazy chatgpt search disagrees on this so would be good to know the correct source of your information to compare. Cheers
ChatGPT isn't always correct its like how people google gives correct results every time. Where in reality its who ever pays the most to google gets the best search positions.
if you really want to do your own research start with an internet search of "vitamin d3 10 000iu benefits" and go from there. its a very deep rabbit hole. Also exposes alot of the BS you get from big phama.
@kungfuman: Yeah I was just asking for your sources to add to my researching. Everyone is different and best to take drs advice.
@Tommohalby: actually no not all doctors give good advice infact of them give bad advice because they don't keep up with the latest research. so never think what you get from a doctor is always correct.
@Tommohalby: medical negligence Australia look that up and you will see the cases it happens more often than you think.
@m0tyrider: Are you saying just believe what they says on an online forum? Yes he or she may be correct but I am just after a source. Can't blame someone for asking that can you…. Do you have some sources to offer?
@kungfuman: Mate, you are choking on the schlong of big pharma.
If we listen to you, now we can't just take D3, we now need to not just also take K2, but ALSO take magnesium.
How much money are you forking over to these companies, yet you're like… haha you losers only accepting 1000 IU (while we can take more than one tablet) and saying that we're being manipulated.
@NatoTomato: D3, K2 and magnesium are all pretty cheap. Like under $100 a year for the 3? Probably less. Big pharma must be loving this. And yes, if you're taking any supplements, those three are absolutely the ones I'd list. Plus NAC.
There were recent studies recommending dosages closer to 10000 IU at the least have no negative outcomes when taking such doses with K2, along with claims you can find benefit at and above 10000. Particularly if you don't get a great deal of sunlight.
@NatoTomato: you don't need to spend money on supplements to begin with if you know what foods and how much sun you need to get all those Vitamins, also it isn't expensive to get a combination supplement that has all 3 Vitamins in one capsule, supplements should always be a secondarily thing when you cant' get access to the right foods and a decent amount of sun.
@kungfuman: I'm not agreeing or disagreeing with you but wanting to know where you got this info from.
Without sourcing what your saying you're coming across a little Cray Cray now. :)
You've said to just Google to find what you're talking about but also saying people are misinformed by just googling it…. Contradictory information.
@kunkfu
I'm not saying you are wrong…
- ChatGPT isn't always correct

- not all doctors give good advice
- ever think what you get from a doctor is always correct.
… but man, there's just too many conspiracies here for me.
googles revenue model has been the same since they were created the more many you give google the better your business will stick out in searchs that how marketing companies operate.
3 year expiry, so a good one to stock up on!
I am searching for the expiry. Where did you find 3 years? Thanks
I bought this one a week ago and decided I should stock up more if it was long expiry. The one I bought expires 05/2028.
Sick! That's awesome then. Thanks!
Never see the sun. You can just use this as an alternative
not really if you have 20 to 30 min of direct sun you will get about 10,000 to 20,000 IUs of active Vitamin D, so 1000 IU in a supplement will not give you any benefit. I mix between 10,000 IU supplements and direct sun light all the time. I almost never sick I have alot of energy all the time, and I am never Vitamin D deficient. I recommend people get a Vitamin D blood test done every month and you will see how deficient you really are if you only take 1000 IU of Vitamin D. Even my doctor is up with the latest research on Vitamin D and know 10,000 IU is the minimum and my blood tests reflect my levels well into the green or higher. As I said you will only know this when you try it.
You would want to stop taking vitamin D a few days prior before a blood test. It can give high readings because it gets stored in your blood for a few days, so stop taking it for a bit then get a blood test for a true representation of the level.
Not as straight forward as that. I commute bike ride like 8 - 10 hours a week.Doc said critically low vitamin D. Plus having any pigmentation doesnt help. I think last year, Strava says I was active 420 hours, almost all in daylight.
For someone who generally at least attempts a 20min walk daily during lunch (excluding any indoor gym blah blah) would I see any tangible benefit from this?
I recognise the target audience is probably those who have sensitivies to sun, not able to get around as easy etc, but I guess is there a benefit for those who generally would have enough sun exposure?
YES… also no need to expose your neck, face and ears to skin cancer
The sun is good for you
Best thing is get a blood test from your doc and see your levels. If sufficient, no need to waste your $… goes for any other supplement.
Recently had a blood test and was low on vitamin D. Also learnt that if you have a darker skin tone its harder for the body to absorb vitamin D from the sun.
Get tested as sun does bugger all for many. Then decide what your target level is and figure out how much (if any) you should take. My target is 120nmol/l and I take around 6 times as much as these tablets daily and still around the 90mark. I'm also out in the sun for abt 2hrs a day. So YMMV.
On a sidenote this isn't cheap. You get much cheaper on iherb.Thanks for telling us about iherb, these prices really are good after looking. Is there a catch? Is this US based company this significantly cheaper for any reason? Only reason I can think of is online distribution - no brick and mortar shop cost.
Swisse is a name-brand with a reputation. Though I'm sure most of the supplements on iherb are 3rd party tested, these companies do not exist in Australia and if something happens to you, they will deny responsibility.
Are you asking why we get gouged in Aus on certain items? :)
you will not see a benefit from 1000 IU of d3 supplements, you would be getting much more Vitamin D from the sun in your walks than the pitiful 1000IU you get in these supplements, which is nothing. save your money.
D without k2 is waste
Why? My doctor said its find to take as is… doesn't require other vitamins to absorb it… He did say that your body absorbs Vitamin D very slowly so wont be boosting your levels for at least a month+ Beats eating sardines and other foods high in V#D
It works much more efficiently with K2, otherwise your body can build up too much. Your Dr is wrong.
I read it same but not sure if it is true. Any doctor here?
See Dr Berg vitamin D on YouTube for one explanation.
He is a Chiropractor! Don't take medical advice from a Chiropractor.
K2 transports calcium to where it is needed (bones).
There is pretty good evidence that it helps with bone health. There is some decent evidence that it reduces calcification in arteries, but studies are ongoing.
We don't really know what is the ideal intake of K2 and it can be hard to get it from your diet. K2 supplementation may be worth it, even if you don't need Vitamin D supplements. D without k2 isn't a waste, but I would personally go with a supplement with K2.
Not a DR.
VERY BROAD AND UNTRUE statement.
Nothing works as good as ostelin
Based on what? Isn’t it exactly the same form of Vit D?
thats what i thought :)
Based on life experience of trying majority vitamin D brand
seems both similar products contain 25 micro-grams of cholecalciferol 🤔
Cholecalciferol is a dietary supplement that is used to treat vitamin D deficiency
Ostelin works nothing as good as ostelin
Yeah so far I've seen ostelin works the best.
It's what my doc recommended years ago too.
I brought a buncha Swisse supplements and they're all expired now, didn't get much use of them haha…
I mentioned it to a friend and they said this brand is trash so idk.
Not saying it is but I'm kinda not sure just based off that one friend now
I feel like 18 year old girl is not the core demographic of this site. I'd be surprised if they represented more than 20% of their population proportion.
Actually I had a severely bad vitamin d deficiency back during the covid lockdown years, I could barely walk after returning to school!
If you wanna live a long life miss 18 year old dont risk going out into the Australian sun too much. Its no joke!
Bad joke is bad.
Don't we allll
Does 1000IUs actually have any effect? Don't you need like 5000- 10000IUs daily?
My doctor said your body isnt very good at absorbing and storing Vitamin D fast.. it can take months of taking 1000IU's per day to get a higher reading in your blood test.
Taking 1, 2 or 5 tablets per day is wasting money as you are still absorbing it really slowly.
Lots of older people end up getting vitamin D injections similar to Vitamin B12 injections.. it boosts your level quicker.Been on 5-10k per day for the past 12-18mths with K2/mq7, per general advice to boost immune system following a year plus of continually being infected at the seemingly the slightest cough from anyone nearby and having a run of shingles and other signs my immune system was suboptimal.. About to recheck via blood tests.
Need to source from USA, iherb etc to get decent price on these I find.
please update when you get blood test results :)
do you also have any iherb reccs? I'm cautious as to which brands to pick given the foreign nature. I have been looking at this one
I've used both California Gold and Now.
Pay close attention to advertised expiry and ensure it will last out for your daily dose.I buy my K2/MK7 from Chem warehouse, but might try the combined Now capsule next time.
One thing to note, if you don't eat beef then California gold state their capsules are made oth fish gelatin.
I've heard a doc say ya should take 1000IU to maintain what level you're at and like 2000IU daily if you're trying to improve your intake.
Or the occasional 3000IU here and there works too
1 tablet a day will still improve your level. But it will take months to show up in blood tests.
Your body stores vitamin D very slowly. Takng heaps of tablets at the same time is only offering a small gain and a waste of money also
If you take too much supplemental or prescription vitamin D, it can lead to vitamin D toxicity.
Dont follow advice online. Read and follow the instruction on the packaging and talk to your doctor if you need more then whats being offered
Sorry, i should clarify that my doctor said that haha.
It's worked for me.
But yeah my last blood test around a year ago still showed I have a deficiency. I very much doubt I'm taking too much.
Daily D.
Need VD everyday. Nice price.
I usually get the Wagner brand 1000iu 500pcs for $15.59 from Chemist Warehouse. My body converts Vitamin D really well, all I need is 2000IU/day to have levels of 150 nmol/L. I used to take 4000IU/day during winter, but levels were getting up into the 185 nmol/L range, so dropped back to 2000IU/day
Good info here
“Vitamin D” Research
What and how the world is beginning to
learn about the importance of “Vitamin D”1000IUs works for me, health related improvements are always case by case basis, 1000-2000 IUs keeps me around 80-100 with blood test, yet some people need 5-10k IUs + Vit K boosters and that works for them phenomenally.
Literally a YMMV and no one is the same, blood tests and bi-annual/annual checkups is the way to go, the variance is huge with Vit D levels and everyone should act based on their own blood tests and not the experience of others. Many people may be severely deficient in Vit D and never know it if they do not do a blood test to check, I was one of those people and caught it whilst I was still young before the issues with low levels of Vit D showed up. I had to take 5-10k IUs to boost my Vit D levels to the recommended levels before tapering down to 1000IUs. So in a sense Ive benefited from both high IU intakes and low intakes.
Blood test > everything anyone else recommends then act on the results -> recalibrate Vit D intake based on subsequent blood test results.
Good price.
