Vitamin K2 Won't Save You From Vitamin D Mistakes in Sleep Apnea

Vitamin K2 is often treated like a safety net for vitamin D.

But K2 cannot fix the wrong dose, poor absorption, bad timing, missing nutrients, or the deeper problems created by sleep apnea.

In this episode, I break down the biggest vitamin D mistakes people with sleep apnea make, including:

• Why taking K2 does not make excessive vitamin D automatically safe
• Whether taking vitamin D at night could interfere with sleep
• The overlooked role of magnesium
• Why blindly adding zinc can create a different problem
• Why your meal, dose, medications, and health status matter
• Why low vitamin D may sometimes be a consequence of sleep apnea, not the original cause

Correcting a deficiency can be useful. But raising a blood test number is not the same as fixing the airway, breathing patterns, oxygen delivery, or the factors disrupting your sleep.

Yeah, well, if the damn sun would ever come back, maybe I could get some. Half of the summer has been nothing but clouds and humidity.

I understand what you are saying about monitoring the PTH hormone blood test to see if vitamin D3 is working correctly because when I took 4000 IU vitamin D3, the calcium level was too high and the PTH hormone blood level was too high also. I was diagnosed with hyperparathyroidism and was told by a specialist that I needed to have surgery to take out the parathyroids that weren't working correctly to regulate the PTH hormone and the calcium level. Long story short, I went to another specialist who understood supplements better and she said to take 1000 IU vitamin D3 and only 200-250 mg. of calcium from supplements and the rest of the 950 mg of calcium from foods and the blood levels of D3 level, calcium, and PTH hormone went back to normal. No need for parathyroid surgery. With a lowering of the Vitamin D3 supplement from 400O IU to 1000 IU daily and getting most of the calcium from foods, it regulated the PTH hormone level and the calcium level. The doctor advised to take 1000 IU from April through October and 2000 IU from November through March when the sun's rays aren't as strong to help us in vitamin D3 production. This has helped me to regulate my vitamin D3 level year round along with getting morning sunshine outside and keep the PTH and calcium levels in the normal range. As always, please speak to your doctor about your health issues and decide with your doctor what you should do. Everyone's health is different and requires a personal medical approach.

Merci Dylan pour ce sujet c'est vraiment vaste par contre c'est un peu étonnant qu'il faut se supplémenter de 8 mg de zinc et 1 mg de cuivre et c'est vraiment étonnant pour éviter les calcification des artères et oui malheureusement et qui se dit de courir très vite pour les magasins à pied mais je n'ai pas ressenti cette fameuse ivresse du couvreur malheureusement mais il faut sûrement avoir une intensité extrême pour l'obtenir

The selenium content of Brazil nuts depends heavily on where the trees grew. The amount of selenium in the soil varies enormously between regions, so one Brazil nut might contain several micrograms of selenium, while another from a different area can contain many times more. Since you usually don’t know the exact origin and soil conditions, you also don’t know how much selenium you are actually getting.

This makes Brazil nuts a poor choice for precise selenium supplementation. You can easily get too little — or occasionally far more than intended — especially if you eat several nuts every day.

There is also the issue of natural radioactivity. Brazil nuts naturally accumulate radium from the soil because their roots absorb minerals very efficiently. As a result, they can contain higher levels of naturally occurring radioactive elements compared with many other foods. This does not mean they are dangerous in normal amounts, but eating large quantities every day for long periods is unnecessary exposure.
