Massive new vitamin D study just dropped — and it’s getting zero mainstream attention A 4-year trial with 25,000 adults across the US (led by 140 researchers) found: Vitamin D3 supplementation significantly preserved telomere length (only 1 year of aging in 4 years). This follows a 10-year Canadian study... show more

Massive study (25,000+ adults, 4 years, published 2025 in Am J Clin Nutr): Daily 2,000 IU vitamin D3 preserved telomere length — equivalent to slowing biological aging by ~3 years! Telomeres (DNA caps that shorten with age) shortened significantly less in the D3 group vs. placebo — hearts, cells, and overall aging markers looked younger. Marcel James highlights: This builds on prior research (e.g., Canadian 12,000-person study showing ~40% lower dementia risk with vitamin D supplementation over 10 years). Key: It's about preserving length (not reversing) — so start early (ideally before 40–45) to protect as long as possible. Never too late to start, but earlier maximizes benefit against age-related decline, heart issues, dementia risk, and more. Boosting vitamin D (sun, food, or supplement) one of the easiest longevity levers?

Supplementing with vitamin D could cut your risk of dementia by nearly half In a study of more than 12,000 older adults, those who supplemented with vitamin D were 40% less likely to develop dementia over the following decade And after just 5 years, 84% of vitamin D users remained dementia-free compared to only 68% of non-users This benefit even extended to people with mild cognitive impairment and the APOE4 gene—a major genetic risk factor for Alzheimer's disease

Vitamin D just got a serious upgrade. A new study found that taking 2,000 IU of vitamin D3 daily for four years significantly slowed telomere shortening — the biological countdown that accelerates aging and age-related diseases. Researchers saw clearer protection in adults 50+ compared to placebo. Omega-3s didn’t show the same effect. It’s not a miracle cure, but it adds real weight to vitamin D’s role in fighting inflammation and supporting healthier aging. Even short daily walks in daylight can help your body produce it naturally. What’s your take — are you already supplementing with vitamin D, or does this make you want to start?

Vitamin D supplementation was associated with a 40% lower risk of dementia over a decade. After five years, 84% of supplement users were dementia-free compared to just 68% of non-users in a study of over 12,000 people. Vitamin D reduced dementia risk by 33% in adults with mild cognitive impairment or APOE e4, a key genetic risk factor for neurodegenerative diseases. Vitamin D isn’t just a vitamin—it's a steroid hormone regulating over 2,000 genes critical for brain development, neuroplasticity, and inflammation control. Its roles include clearing amyloid beta plaques and tau buildup, boosting neuron survival via neurotrophic factors like BDNF, and enhancing brain connectivity, particularly when paired with exercise. It’s no surprise, then, that higher vitamin D levels are associated with better cognition, larger hippocampal volume, and lower Alzheimer’s risk. Multiple lines of evidence support this. More than 30 large studies have consistently linked low vitamin D levels to a 50–150% increased dementia risk. People genetically prone to low vitamin D—those with genetic variations affecting vitamin D production or metabolism—have a 54% higher dementia risk. Furthermore, supplementing with 800 IU/day of vitamin D improves memory and cognitive function in people with mild cognitive impairment and more serious forms of dementia. To learn more about optimizing vitamin D levels for cognitive health, including underlying brain-protective mechanisms and practical supplementation protocols, see the latest FoundMyFitness video.

Vitamin D deficiency is the most underrated factor for excessive hairfall and there is no surprise most of us will have Vitamin D deficiency because of our lifestyle. In March 2024, I took a blood test and no doubt, my Vitamin D was pathetically low. I took Vitamin D supplements (Precisely, 4 tablets) in a span of 4 months and my Vitamin D has increased significantly. Me being me, tried to do everything naturally possible from sun bathing in the morning to sun gazing. I came across a study article where it mentioned that traditionally made kumkum(turmeric + lime) will help with better Vitamin D absorption. But this little experiment of mine got me more curious to know why people wore kumkum in our culture and the science behind it. By wearing kumkum in the mid brow area, the power of intuition increased and thus increasing one's concentration. I don't have any evidence whether kum kum supported with Vitamin D absorption but I started to enjoy wearing Kumkum. I feel this little habit of mine is adding character to my personality. Why do you think people applied kumkum on their forehead. Is there a science behind this?

High dose vitamin D supplementation might be doing more harm than good. Stephanie Seneff, MIT researcher: Vitamin D is a signalling molecule, not a nutrient to megadose. It mobilizes calcium — but doesn't control where calcium goes. High dose vitamin D drives calcium into the arteries, leaching it from bones. A 3-year study comparing 400 IU/day, 4,000 IU/day and 10,000 IU/day found the highest dose group had statistically significantly worse bone mineral density. A 2006 study found that calcitriol supplementation (the active form of vitamin D) in young adults with kidney disease increased artery calcification — because calcitriol is taken up directly by cells in the artery wall. Artery calcification is one of the strongest risk factors for cardiovascular disease. An Indian study compared vitamin D supplementation to 20 minutes of daily sunlight in 100 men with severe deficiency. Remarkably — the supplement group had a larger increase in serum vitamin D than the sunlight group. Yet opposite effects on cholesterol: Sunlight group — cholesterol dropped. Supplement group — cholesterol increased. Why? Sunlight and vitamin D supplements take completely different routes through your body. Vitamin D supplements are fat-soluble. The liver has to synthesize cholesterol and release LDL particles just to transport them through the blood. Sunlight stimulates cholesterol sulfate synthesis directly in the skin. The sulfate component makes the molecule water-soluble — transported freely in the blood without being packaged inside an LDL particle. Because cholesterol sulfate is both water-soluble and fat-soluble, it can transfer from skin cell membranes to HDL particles or red blood cells and deliver cholesterol directly to tissues that need it. No LDL carrier required. When you get vitamin D from a supplement instead of the sun, you don't get the simultaneous increase in cholesterol sulfate. The pill doesn't just fail to replicate sunlight. It uses a completely different biological pathway. Seneff: "Vitamin D wants to be subtle. Get out in the sun." "People answer: oh yeah I know, vitamin D is important." "No. Not vitamin D. The sun.” Vitamin D is a proxy for sunlight exposure. The proxy isn't the mechanism.

These are the supplements I give my aging parents: • A daily multivitamin • Vitamin D • High-DHA omega-3s • Ubiquinol (the reduced form of CoQ10) • Sulforaphane Why these? Large RCTs show improved cognition in older adults taking a standard multivitamin, with benefits equivalent to a brain that's 2-5 years younger. For vitamin D, more than 70% of older U.S. adults are insufficient, and aging skin produces far less vitamin D from sunlight (a 70-year-old makes roughly 4x less than their 20-year-old self). DHA is a key structural fat in the brain and supports cognitive function, especially important with aging and neurodegenerative risk, while CoQ10 supports mitochondrial energy production as levels drop with age. Finally, sulforaphane is a powerful activator of Nrf2, the body's master stress-response pathway, up-regulating glutathione and phase II detox enzymes.

We know the medical establishment lied to us about COVID. And according to esteemed physician Dr. Paul Marik, they are also lying to you about the sun. Here's a few things about Vitamin D that Big Pharma doesn't want you to know: #1 - "If you’re vitamin D deficient, it increases your risk of getting cancer.” “There’s a linear relationship between vitamin D deficiency and cancer. And the further you go away from the equator, the less UVB you get, the greater your risk of cancer. This has been well established!” drpaulmarik stressed. #2 - "Vitamin D is highly effective for the treatment of depression.” It’s also “very important for the immune system,” Dr. Marik added. “People don’t like vitamin D. They just don’t like it because if people took vitamin D, [they] would reduce the risk of cancer — would reduce the risk of many diseases." #3 - “If you avoid the sun, it increases your risk of dying [prematurely] by about 25%.” Dr. Marik recommended going into the sun for about 30 minutes a day. He advised not to use sunscreens because “it defeats the purpose.” “In fact, there’s some data that sunscreens increase your risk of melanoma — paradoxically.”

Your doctor says your vitamin D level of 22 is "normal" — but what if that cutoff was based on a statistical error? A peer-reviewed study found the IOM miscalculated the RDA by 15x: it should be ~8,800 IU/day, not 600. And vitamin D isn't even a vitamin — it's a steroid hormone that regulates 200+ genes. Here's what the science actually shows.
