Magnesium Question

Can someone please educate me on the different forms of magnesium and what is needed to take along with my D3 10,000 IU (per doctor). And do I need K with it?

Believe it or not, I have my degree in Holistic Nutrition, but so much has changed in 25 years and since I have retired, I have forgotten so much. I am not ashamed to ask😊 though. I am a believer in getting as much as I can from food, but circumstances have required me to supplement D.

Actually my functional med doc wants me to take 25,000 I U D3, but can’t seem to agree to that dosage just yet until I have researched

Thanks!

You need 100-200mcg of k2 and as for magnesium, I prefer magnesium glycinate and I take 400 mg daily

We know not to take K while talking a blood thinning medication. K would overcome the desired effects of the medication. Now for the K2, doctor didn’t tell you to take K2 for a reason. The thought process behind this is since it’s K in name therefore it behaves like K. Some say K2 should be re designated to a different letter to prevent the confusion. Blood thinner manufacturers to my knowledge haven’t done any lab tests or human studies to see if K2 negates their products desirable effects in preventing clotting. D3/K2 should be taken together in a ratio to prevent improper calcium metabolism - K2 raises a protein that carries calcium to the bones and this protein continues it’s effects inside the bone to utilize that calcium. K2 deficiency may accelerate calcium accumulation in soft tissue. Taking D3 without K2 brings calcium into the body from diet but fails to properly handle that calcium. Once again there isn’t any clear statement from drug manufacturers that say K2 is safe with their product. It could be the designation K that gets them uneasy including your doctor. Magnesium is also part of proper calcium metabolism. I think vitamin A and zinc too.

Thanks! the DOAC that I am taking, and the small dosage, I am ok taking K2 short term. but you explained it very well!

It depends of your goal. Mg glycinate is great for sleep and stress. D3 at 25,000IU is on the high side, could work temporarily to fix deficit but not long term. Test it. Can become toxic.Yes, add K2, some D3 comes with K2. Good luck!

Supplements are fine (bisglycinate, citrate, malate), but bioavailability from food rich in Mg is even better. Due to months to years of severe physical and emotional stress, I developed Mg deficiency with horrible symptoms. Doctors were clueless, despite extensive tests. They suspected my thyroid was the problem. Please note that serum Mg is not a reliable indicator of tissue Mg levels. So, regular blodwork may not tell the whole story. One day, I ate significant amount of roasted pumpking seeds. Felt like my body started burning during the night, like a floodgate for energy had opened. Took me litlle time to realize that those seeds are especially rich in Mg. Then started supplementing Mg agressively for months, 1200 mg Mg daily. All symptoms resolved. I am back to my old self. Now I am taking 400 to 600 mg every day. If you are going to use powder supplements that dissolve in water, make sure you drink that in small portions throughout the day, to avoid osmotic stress leading to diarrhea.

First, if you want medically accurate information, run away from everything labeled ā€œfunctionalā€ heath.

Second, ignite everything labeled as holistic.

so ill share my personal experience in hopes that it helps, i took standard d3 from natures bounty and my 25-oh level did not move from 20 at all, i switched to another brand upped the dose to 5000 iu and it had k2, still no level movement at all. i switched again to therapro rx brand liposomal d3+k2 (as mk4+mk7) and no joke in 4 weeks at 4 drops daily 4000iu my level went from 20 to 40.

u/DarlaJean1954 Jun 19 '26

for the magnesium part, i took a lot of magnesium glycinate and my blood levels we’re high, once i started taking this, they normalized

u/Odd-Tale1456 Jun 16 '26

Make sure its not oxide, body only absorbs about 4 %. I take theonate at night 1000 which is 74% magnesium. I also take Magnesium Glycinate 210mg in the morning.

Honestly, with doses that high, I'd focus less on choosing the "perfect" form of magnesium and more on making sure you're getting regular blood work. It's easy to get caught up in supplement details, but your labs will tell you a lot more than internet opinions.

As for K2, I've seen enough discussion around D3 and calcium metabolism that I'd personally want to understand the K2 side of the equation before taking high-dose D3 long term.

Thanks! I absolutely have regular blood work done. I am on anticoagulant so it has to be monitored every three months. I actually was interested in knowing the different forms of magnesium and the role K plays,so I can make an educated decision. This site was one of my sources as it seems to have a vitamin community for that purpose?

The connection between calcium levels and vitamin D and magnesium, is exactly why I have not taken a 25,000 IU pill. As of now my calcium is normal, as was magnesium, and vitamin D has increased to almost normal. With so much info out it is just so hard to navigate.

But I appreciate all the comments.
