Not everyone needs K2 or magnesium with D3

I keep seeing many people recommending K2 and magnesium for everyone, so I thought I'd share my view.

K2 and magnesium can be helpful in some situations, but they are definitely not essential for everyone.

This post isn't about specific cases; it's against the blanket advice of taking magnesium and/or K2 together with D3.

If you're using magnesium glycinate for better sleep, or K2 for issues like tonsilloliths, that's a different story. (Side note: Theanine can also help with sleep.)

Also, if you're taking magnesium, K2 or any supplement without a prescription, be aware of the RDA and the TUL (Tolerable Upper Limit).

The TUL for supplemental magnesium is 350 mg for adults - which is below the RDA!

Many brands sell 400 mg of magnesium per dose, which is risky and has been linked to problems.

I see many people suggesting K2 and magnesium to everyone. They are helpful in some cases, but they are definitely not necessary.

This isn't about targeted use cases; it's a pushback against the blanket suggestion to take magnesium and/or K2 along with D3.

If you take magnesium glycinate for better sleep, or K2 for issues like tonsilloliths, that's a different scenario. (Side note: Theanine can also be considered for sleep.)

It's like those who pop Evion 400 mg like tic‑tacs - that's a very high dose.

I recall that same person made a video saying vitamin D won't be processed if you're low on magnesium, and now he's calling it influencer hype.

Hey, I have a couple of questions. First, I've read that it's practically impossible to know if you're magnesium deficient just by normal tests. You can look it up if you want.

Second, my understanding is that RDAs are the minimum amounts needed to avoid deficiency diseases. They don't necessarily correct a deficiency or give therapeutic benefits. To see a noticeable effect you'd likely need a much larger amount than the RDA. I'm basing this on what I've gathered from reputable YouTube doctors with proper degrees, but I'd love someone to confirm.

People should really understand what RDA truly means.

We don't allow reel posts, but I'll let this stay because the topic is important and not often discussed.

He is right that K2 doesn't have sufficient evidence currently. D3 and magnesium have been part of my supplement stack for years, but I'm still unsure about adding K2 permanently. He also missed calcium, which is part of the bones and joints stack, and I'm conflicted about that too.

If anyone is taking K2, my recommendation is to use it for a limited period - 3 to 6 months max. Usually that's enough to address general deficiencies.

He is wrong about two things:

1. You can't accurately test for magnesium deficiency. A serum test isn't enough. Some cellular tests exist, but their accuracy is unclear.

2. An average person is unlikely to get sufficient magnesium from diet alone.

3. Current clinical practice uses weekly D3 doses. I think patient compliance should be a priority, but anyone who cares about health should take daily doses, as daily intake absorbs better. We have enough anecdotal data to see daily doses work better for D3.

d3, k2, mg, zinc, copper

The first three are related, and the last two are related.

I think that's proven, and on that basis people advise taking d3 with these to keep the body balanced.

We Indians barely get k2, literally, so it's often recommended.

K2 helps prevent calcium from depositing in unwanted places, but taking k2 and mg in unbalanced amounts can cause noticeable issues.

High doses of d3 alone can lead to calcium buildup in the blood, which may affect the kidneys, so k2 is suggested.

That's the knowledge I have - can someone correct it?

Great explanation!

[Pooja]

I think the whole concern about magnesium stems from the idea that vitamin D supplementation depletes your magnesium reserves faster, and most people today barely meet the daily magnesium intake requirement.

K2 is aimed at improving vitamin D absorption into bones rather than into arteries.

He sounds like he's reading an AI script, to be frank.
