Who Here Takes Vitamin D Supps?



Any suggestions for the best quality vitamin D supplements?

Also, something to look into, from some random research I did I found out that vitamin k (more specifically k2) is important when supplementing vitamin D otherwise you may be doing yourself harm.

Vitamin K Prevents Vitamin D from Promoting Heart Disease

Vitamin K engages in a delicate dance with vitamin D; whereas vitamin D provides improved bone development by helping you absorb calcium, there is new evidence that vitamin K2 directs the calcium to your skeleton, while preventing it from being deposited where you don't want it -- i.e., your organs, joint spaces, and arteries. A large part of arterial plaque consists of calcium deposits (atherosclerosis), hence the term "hardening of the arteries."
Vitamin K2 activates a protein hormone called osteocalcin, produced by osteoblasts, which is needed to bind calcium into the matrix of your bone. Osteocalcin also appears to help prevent calcium from depositing into your arteries. In other words, without the help of vitamin K2, the calcium that your vitamin D so effectively lets in might be working AGAINST you -- by building up your coronary arteries rather than your bones.
This is why if you take calcium and vitamin D but are deficient in vitamin K, you could be worse off than if you were not taking those supplements at all, as demonstrated by a recent meta-analysis linking calcium supplements to heart attacks.
This meta-analysis looked at studies involving people taking calcium in isolation, without complementary nutrients like magnesium, vitamin D and vitamin K, which help keep your body in balance. In the absence of those other important cofactors, calcium CAN have adverse effects, such as building up in coronary arteries and causing heart attacks, which is really what this analysis detected. So if you are going to take calcium, you need to be sure you have balanced it out with vitamin D and vitamin K.

This has kept me from supplementing D and calcium as of yet as I need to do more research on how to have sufficient vitamin k2 levels. I've added chicken livers to my diet as one source of vitamin k2, but am unsure quite how much I need. Anyone else up to speed on the subject?
 
Every day I take calcium, magnesium, vitamin d, a multi vitamin, and fish oil.

What I would recommend for everyone though is calcium. It's super hard to get enough calcium.
 
Lol, hermits.

Take a multi, go outside.

Going outside is not enough. There needs to be good amount of sunshine first and its difficult during the winter. And even with sunshine, you need to expose your body to it, rather than just face and hands. If I lived in a warm climate like the canary islands where its sunny all year round, I won't need to take the vitamin daily as I could just go into my garden with my shirt off for 15 minutes.

I take 5000UI per day (when I'm not out and its dull) of vitamin D3 during summer and 10000UI per day during winter. Been doing this for around 3 years. Its hard to overdose on D3 as your body only uses what it requires. Past few months I've changed the brand of the D3 I'm taking, so back to 5000UI per day.

Does it say what kind of vitamin d this applies to? There are different types. D3 is the one we should be taking.

Anyway, for the past 3 months I've been taking a sublingual tablet of 5000IU vitamin D3 combined with 50 mcg vitamin K2 daily:

Michael's Naturopathic, Vitamin D3 + K2, Natural Apricot Flavor, 5000 IU, 90 Sublingual Tablets - iHerb.com

I started taking it because I read that k2 is good for us in many ways including collecting calcium from the arteries and despositing where it should be, that is in the bones. Chew and let it dissolve under the tongue. This way the vitamins gets absorbed better as it does not need to pass through our stomach acid where some could get destroyed.

That brand is really good value as there are bottles of vitamin k2 alone that cost more than this combination.
 
I am taking 10000 IU of Vitamin D3 per day (soft gels). The brand is NOW Vitamin D-3.

Initially it was 5000 IU after I woke up every morning and 5000 IU before I slept every night. With this protocol, I was having hard time sleeping. I believe that human bodies are designed to take Vitamin D in the mornings.

Now, I take 5000 IU in the mornings and 5000 IU in the afternoon. I have no more sleeping problems. Positive things I notice is that I can lift more weights when I was in the gym and my sexual drive is very high. Whenever I combine Vitamin D-3 and zinc, my semen is less watery and more solid.
 
You shouldn't be taking multivitamins unless you are severely deficient in that vitamin. Even then you should be doing everything in your power to try to get that vitamin naturally. There have been a bunch of studies that show that taking vitamins in pill form generally do more harm than good.

I'm surprised a lot of the crazy health conspiracy theorists on this form get all riled up about toothpaste while taking a multivitamin every day.

The only nutritional supplement I'd ever consider taking is Omega 3, but I've replaced that by eating wild caught salmon every day. And incidentally, a serving of salmon also has plenty of vitamin D in it.
 

Hard to overdose != can't overdose. We can overdose on anything even water can kill us and it has happened to some retard before. From your link

Overdose has been observed at 1,925 µg/d (77,000 IU per day)

Who takes 77,000IU per day unless they are extremely deficient in the stuff. The problem with that quote as well is that it just says vitamin d overdose, and does not stipulate if its cholecalciferol overdose.

Take for example this statement on your link:

Excessive exposure to sunlight poses no risk in vitamin D toxicity through overproduction of vitamin D precursor, cholecalciferol, regulating vitamin D production.

Vitamin D3 is cholecalciferol. Though you can say that the difference is we are taking cholecalciferol orally and not producing it via sunlight.

From:

Cholecalciferol - Wikipedia, the free encyclopedia

The 4,000-IU cut-off was determined by the Institute of Medicine in 2010 after reviewing the then-current medical literature, finding that the dose for lowest observed adverse effect level is 40,000 IU daily for at least 12 weeks,http://en.wikipedia.org/wiki/Cholecalciferol#cite_note-pmid10232622-8

So you need to take 40000IU daily for 12 weeks for the lowest observed adverse level.

For certain cases, astronomical amounts have been used in single doses:

Also, there is a therapy for rickets utilizing a single dose, called stoss therapy in Europe, taking from 300,000 IU (7,500 µg) to 500,000 IU (12,500 µg = 12.5 mg), in a single dose, or in two to four divided doses.[11]

An advantage to taking Omega 3 supplements versus eating fish is you have much more control over the amount of mercury you're consuming. I eat fish nearly everyday and give few fucks about mercury but it's something to think about.
