They Knew THIS About Vitamin D — And Millions Are Still Getting Sick

Vitamin D deficiency is widespread due to outdated recommendations and insulin resistance, impacting immunity, metabolism, and overall health.

Key Takeaways

  • Vitamin D deficiency is common and often undetected by standard lab tests.
  • Current vitamin D intake recommendations are too low for optimal health, especially in older adults and those with insulin resistance.
  • Vitamin D plays a systemic role beyond bone health, affecting immunity, metabolism, and inflammation.
  • Proper activation of vitamin D depends on cofactors like magnesium and vitamin K2.
  • Vitamin D toxicity is rare; the bigger concern is widespread insufficiency due to lifestyle and metabolic factors.

What the video covers

  • Current vitamin D recommendations (600 IU) are based on outdated population averages and do not account for individual variability or genetics.
  • Many people can have normal lab results yet remain vitamin D deficient at a cellular level, affecting immune function, inflammation, and insulin resistance.
  • Vitamin D acts as a steroid hormone with receptors in nearly every cell, influencing muscle synthesis, immune regulation, and neurotransmitter production.
  • Aging, indoor lifestyles, sunscreen use, and skin changes reduce natural vitamin D synthesis, making the standard dose insufficient for many, especially older adults.
  • Insulin resistance is a leading cause of vitamin D deficiency, with vitamin D directly impacting insulin secretion and glucose metabolism.
  • Vitamin D activation requires magnesium and vitamin K2; deficiencies in these cofactors impair vitamin D function even if blood levels appear normal.
  • Vitamin D toxicity is rare and usually requires extremely high doses over long periods; insufficiency is a far more common and serious issue.
  • Sun exposure for 5-10 minutes midday can produce about 600 IU of vitamin D, but ancestral human exposure was likely much higher.
  • Supplementation with vitamin D3 combined with K2 and magnesium is recommended for effective correction and optimization.
  • Large institutions are slow to update vitamin D guidelines despite emerging evidence showing current recommendations are inadequate.

Answers

Questions about this video

Can you have normal vitamin D lab results but still be deficient?

Yes, because vitamin D activation occurs inside tissues and cells, normal blood levels may not reflect true functional sufficiency.

Why are current vitamin D recommendations considered too low?

They are based on outdated population averages and do not account for individual differences, genetics, or the higher needs of aging adults.

What role does insulin resistance play in vitamin D deficiency?

Insulin resistance is a major cause of vitamin D deficiency, as vitamin D receptors on pancreatic beta cells influence insulin secretion and glucose metabolism.

Speaker A
You followed the recommendation. You took your 600 international units of vitamin D, and your labs came back normal. And guess what? You could still be deficient. Still inflamed, still insulin resistant, still getting sick.
00:15
Speaker A
And they knew this. The number was wrong, and it barely changed. Years ago, official recommendations were based on population averages, not individuals, not variability, not genetics. They assumed that most people respond to the same vitamin D. That's like grading
00:33
Speaker A
every student on the class average and assuming everyone passed when in reality half the class could be failing. Later on, independent researchers reanalyzed the exact same data set that was used to set the recommended daily allowance. And what they found was crazy. The gap
00:52
Speaker A
wasn't small. It wasn't minor. It wasn't just close enough. The number required to ensure adequacy for nearly everyone was dramatically higher than 600 international units. And yet the recommendation barely moved. Now I want you to pause for a second. If this was a
01:09
Speaker A
small math mistake, it would have been corrected quickly. But it wasn't. And that's where things get uncomfortable.
01:15
Speaker A
You see, vitamin D deficiency doesn't feel dramatic. It's silent. It's cellular. Internal. You don't feel it until the consequences show up as symptoms. Here are the following most common symptoms: slower recovery, mood shifts, weaker immunity, muscle loss, and blood sugar instability. And here is
01:34
Speaker A
what's wild. You could have normal labs and still be vitamin D deficient because activation happens inside tissues, inside immune cells, inside muscle cells, and inside the brain. So when someone says your numbers are fine, the real question is fine for what?
01:52
Speaker A
Preventing rickets or for optimizing human biology? That's a big difference. So, let's connect this to real life.
01:58
Speaker A
After 45, muscle mass declines, insulin resilience drops, inflammation rises, and insulin sensitivity weakens. Also, cognition becomes more vulnerable. See, vitamin D is not just a vitamin. It's a very important steroid hormone, and it plays key roles in T-cell activation.
02:19
Speaker A
Yeah, that's your immune system. Cytokine balance. It's buffering inflammation, muscle protein synthesis, which is the key for insulin sensitivity, insulin repair sensitivity, and neurotransmitter production. This isn't fringe. As a matter of fact, vitamin D receptors exist in nearly every cell inside of
02:39
Speaker A
your body, not just bones. So, when levels are insufficient, it's not a bone problem. It's a systemic regulation problem. That's why vitamin D deficiency has been associated with increased respiratory infections, mood disorders, even things like metabolic syndrome, autoimmune activity, and increased
02:59
Speaker A
cancer risk. Not because vitamin D is magical, but because it's foundational. And look, it's not about being unhealthy. You could be thin, active, eating organic, lifting weights, even tracking macros and calories, and still be insufficient. Why? Well, because we
03:15
Speaker A
live indoors, we avoid the sun midday. We wear SPF sunscreen constantly, and we sit behind glass which blocks UVB. And guess what? Aging skin synthesizes less vitamin D. By age 60, skin produces about 25% of what it did at 20. And that
03:36
Speaker A
is huge. So the 600 international recommendation for a 25-year-old indoor office worker is the same recommendation for a 62-year-old with lower skin conversion capacity. Make it make sense.
03:49
Speaker A
It doesn't make any biological sense. But here's the craziest fact about vitamin D that nobody talks about.
03:56
Speaker A
Chances are you've never heard this before. The number one cause of vitamin D deficiency is insulin resistance.
04:04
Speaker A
Studies show that 93% of Americans are insulin resistant. There was a published analysis looking at the relationship between low vitamin D levels and insulin resistance. Not theory, actual clinical data. And here's what they found. First, vitamin D receptors exist directly on
04:23
Speaker A
the pancreas, specifically on the beta cells. That's where you produce insulin. So vitamin D isn't just floating around for bone health. It's interacting directly with the machinery that controls your blood sugar. The researchers found that when vitamin D
04:36
Speaker A
levels are low, markers of insulin resistance go up. Fasting glucose tends to be higher, and your risk for metabolic diseases and the metabolic syndrome increases. In other words, low vitamin D isn't just about weak bones. It's associated with impaired blood sugar
04:53
Speaker A
regulation. Now, here's where it gets even more interesting. Vitamin D appears to influence insulin sensitivity through multiple pathways. Number one, it regulates inflammation. Number two, it influences calcium signaling inside the beta cells, which directly affects insulin release. And number three, it
05:13
Speaker A
impacts gene expression involved in glucose metabolism. That means vitamin D isn't a one-pathway effect. It's systemic. And if you're over 45, when insulin resistance becomes more common and your vitamin D is barely scraping the minimal threshold, this could be a
05:32
Speaker A
metabolic blind spot. Now, I'm not saying vitamin D cures diabetes and insulin resistance. But I am saying this: vitamin D influences insulin secretion, inflammation, and metabolic signaling. So why should we aim for the lowest possible acceptable level? That
05:49
Speaker A
is the real question. So here's what's uncomfortable. When the reanalysis happened, concerns were raised, experts debated this. And yet, the number barely changed. You see, large institutions make changes very slowly. Corrections take years, sometimes decades. History has shown us that guideline corrections
06:08
Speaker A
often lag behind emerging evidence. It happened with cholesterol. It happened with dietary fat. It happened with hormone replacement therapy. And here we are again. The system isn't designed for rapid correction. It's designed for consensus stability, but your immune
06:24
Speaker A
system doesn't wait. Your mitochondria don't wait. So, let me ask you something very simple. How much sun exposure do you think produces 600 international units of vitamin D in summer conditions? That's roughly 5 to 10 minutes of midday sun on the arms and
06:43
Speaker A
legs for most people. That's it. 5 to 10 minutes. Do you think that matches the history of human exposure patterns?
06:50
Speaker A
Look, our ancestors weren't getting 600 international units. They were getting thousands daily through sun exposure.
06:58
Speaker A
Now, us modern humans are indoors. We're covered. We're inflamed. We're insulin resistant. And we're stress loaded. And then you're told 600 international units is enough. This mismatch alone should make you pause and reflect and think about it. You see,
07:13
Speaker A
vitamin D from the sun and even from supplements is inactive. It must go through two conversion steps. Number one, the liver turns it into 25 vitamin D. Then number two, kidneys and tissues activate calcitriol. And here's what's really fascinating. Magnesium is
07:31
Speaker A
required for these steps. Without magnesium, vitamin D doesn't activate efficiently. And it's not just magnesium. Vitamin K2 helps regulate calcium placement. Without K2, calcium can accumulate improperly. So if someone takes small doses of vitamin D, has low magnesium, has low vitamin K2 levels,
07:54
Speaker A
chronic inflammation, insulin resistance, they may not even activate the vitamin D even if their blood levels look okay. You see, it's not just the dose, it's the activation. Now, let's talk about something that I get asked a lot. Vitamin D toxicity. Is it possible?
08:10
Speaker A
Yeah, it might be possible. Is it common? No. I mean, it's very rare. Toxicity usually requires extreme high intake of vitamin D over extended periods of time, often well above 40,000 international units daily for months without supervision. So, the real issue
08:30
Speaker A
isn't toxicity, it's widespread insufficiency, especially if you live in northern latitudes, have darker skin tone, you're an older adult, or you're overweight and obese. See, vitamin D gets sequestered in fat tissue. And the deficiency in vitamin D directly impacts
08:48
Speaker A
your immune regulation far more commonly than toxicity affects calcium balance.
09:05
Speaker A
if you understand how critical vitamin D is for your immune system, muscle strength, brain health, and metabolic stability, then this next step is simple. You can't always rely on sunshine. You can't control winter, and most adults are deficient without even
09:20
Speaker A
knowing it. That's why I use and I partnered with Myioscience vitamin D, not for mega dosing, but for intelligent correction. I love this product because it includes vitamin D3, the vitamin K2, and the magnesium support all in one
09:36
Speaker A
product. And that's important because just taking vitamin D without K2 can misdirect calcium. And vitamin D without the magnesium doesn't even activate properly. This is about precision, not hype. So, if you're serious about protecting your long-term health, this

11:26
Speaker A
when possible. Midday sun is between 11:00 a.m. and around 2 p.m. No sunscreen initially, and make sure your arms and legs are exposed. I would also recommend you take off any sunglasses.
11:38
Speaker A
Here's the cool thing. When you eliminate rancid fats like seed oils and vegetable oils and fish oil, it's really difficult to get sunburned. Second step is the intelligent supplementation. Use a high quality vitamin D3 with the K2 like the myioscience one. Then test your
11:53
Speaker A
levels every 90 days if you can and aim for optimal levels, optimization, not bare minimum survival. Step three is the co-actor support. It's the magnesium hydration. That's it. No overhaul, no detox, no extreme protocol, just correction. Now, there are some foods
12:11
Speaker A
that are rich in vitamin D that I would recommend. That's going to be eggs with the yolk, mushrooms, and wild caught salmon. Look, if you're over 45 and you've been doing everything right, you deserve to know this, not to panic, but
12:24
Speaker A
to understand, because silent deficiencies don't announce themselves, they accumulate. So, here's my request. This has opened your eyes. Send this lesson to one person, someone you care about, especially someone who says, "My labs are normal." And drop the word
12:40
Speaker A
sunlight in the comment section down below. This made you rethink the 600 international units myth. Because the more people understand this, the fewer people will be blindsided by something completely preventable. And if you want to go deeper, watch my next video on
12:56
Speaker A
vitamin D toxicity myths so you can optimize safely. You don't have a bad immune system. You may just have an underup supported one and that's fixable. Now, let's get to the questions you submitted on this topic. Isn't 600
13:09
Speaker A
to 800 international units the official recommendation? Why would they recommend something so low, so little? Because the RDA, the recommended daily allowance, is designed to prevent severe deficiencies like ricketetts, not to optimize immune, metabolic, or cognitive performance. You
13:27
Speaker A
see, preventing disease is very different than optimizing your biology. Ben, isn't 20 nanogs per milliliter considered sufficient in terms of your vitamin D blood levels? It It's so crazy to see that report from your labs that show your vitamin D reference ranges is
13:45
Speaker A
between 20 and 95 or 20 and 80. If your vitamin D levels are 20, heck, if it's 35, you're vitamin D deficient. Even though your doctor will not flag it cuz you're in the reference range, you want your vitamin D levels to be above 60. I
14:01
Speaker A
constantly check mine and I'm always above 60. Does vitamin D really affect immunity? 100%. See, vitamin D receptors are present on your immune cells. It plays a regulatory role in immune signaling and inflammatory balance. It's not just a immune booster, it's an
14:19
Speaker A
immune modulator. Can obesity affect vitamin D levels? Yes, I addressed this a little bit earlier. Let me give some more clarification. See, vitamin D is a fat soluble vitamin and it could become sequestered in your fat tissue, atapost
14:33
Speaker A
tissue. That means individuals with a higher body fat percentage may require even more intake of vitamin D to achieve the same circulating levels. What about magnesium and K2? Are they really necessary or can I just take the vitamin
14:47
Speaker A
D? I don't recommend just taking the vitamin D without K2 and without additional magnesium support. It could create something called a functional deficiency. And again, it's about the activation. You want to activate the vitamin D, not just take it and you're
15:01
Speaker A
literally peeing away your money, flushing your money down the toilet. See, magnesium is required for the vitamin D activation. K2 helps regulate the calcium placement. So, the myioscience vitamin D, I would recommend you take two to three capsules every day
15:16
Speaker A
with food and watch how it changes your levels and watch how it changes how you feel. Now, before I get to the next question, let me give you a free resource here. Now, this is going to help lower inflammation, insulin, so
15:26
Speaker A
vitamin D works more efficiently. And it's very important because if your belly fat hasn't moved in months, even though you've been doing everything right, it's not your fault. You've been lied to. The real problem is visceral fat, insulin resistance, metabolic
15:39
Speaker A
dysfunction, and no one's shown you how to fix it until now. This free 7-day guide flips your fat burning switch on with zero calorie counting, zero guesswork, and meals so simple it feels like cheating. This is your body's reset

Speaker A
button. If you're sick of starting over, click the third link in the description box below or scan the QR code on the screen and take back control. This isn't just the diet. It's the last one you'll ever need. Next question. Is sun
16:07
Speaker A
exposure dangerous, though? Yeah, you don't want to get sunburned, but sun exposure is not dangerous. Sun exposure is critical, and you could actually build up a tolerance to sun exposure.
16:18
Speaker A
So, start with 5 to 10 minutes a day and work your way up to 15 minutes, 20 minutes. Heck, I could be outside for three hours in the hot Miami sun, which I typically do when I play basketball on
16:29
Speaker A
Sundays, and I don't get burnt. You know why? Because I don't eat rancid seed oils and vegetable oils and I don't take fish oil supplementation. When you get that junk out of your body, it's very difficult to get burned. So, the sun is
16:41
Speaker A
critical, but don't get sunburned. Now, you know the facts, you know the truth. Follow the protocol. When you know better, you could do better. And share this with somebody you know. Go get your vitamin D and magnesium. We'll put the
