Vitamin D
I recently had a sinus infection that just wouldn’t go away. I rarely get sick, although I am historically prone to sinus problems. Although this one wasn’t very painful, it just wouldn’t quit. I happened across an article by one of my favorite bloggers (link below) that discussed Vitamin D and its importance in killing viral infections like influenza. I’d been largely treating my sinus infection as either bacteria or fungal with 10 different remedies, with no luck, and I suspected it must be a viral infection. Also, my kids had all had a brief bout of the flu right when my sinus problems started, so that was suspicious. The study I found mentioned something called the “vitamin D hammer,” and I had to learn more. Within 24 hours of trying it, I was significantly better for the first time in a month, and within a few days I wasn’t sick anymore. It was magical.
The “vitamin D hammer” is a one-time dose of 50,000 IU in one day (or 10,000 IU 3 times a day for 2 or 3 days), for adults with viral infections who haven’t been previously supplementing with sufficient amounts of vitamin D before they acquired the infection. As the FDA only recommends 400 IU of vitamin D daily for adults, this is a much larger dose than I’d ever heard of taking. Many people recognize that the FDA recommendation is wholy inadequate, and daily doses of 1,000-5,000 are common. According to the research, it takes almost 9,000 IU per day for 97.5% of adults to reach serum vitamin D levels of 50 nmol/L or more. Some vitamin D scientific researchers advise taking doses high enough to reach serum vitamin D levels of closer to 100 nmol/L, especially while fighting a viral infection like influenza. Up to 75% of Americans are deficient in vitamin D, which is actually a hormone usually produced by the skin’s exposure to sunlight.
According to the researchers from Canada who discovered the “vitamin D hammer”, “The results are dramatic, with complete resolution of symptoms in 48 to 72 hours. One-time doses of vitamin D at this level have been used safely and have never been shown to be toxic. We urgently need a study of this intervention. The cost of vitamin D is about a penny for 1,000 IU, so this treatment costs less than a dollar.”
Another group of researchers interested in the “remarkable seasonality” of influenza noted that the sunshine causes “robust seasonal vitamin D production in the skin; vitamin D deficiency is common in the winter, and activated vitamin D, a steroid hormone, has profound effects on human immunity. [Vitamin D] acts as an immune system modulator, preventing excessive expression of inflammatory cytokines and increasing the ‘oxidative burst’ potential of macrophages” (white blood cells found at sites of infection). His research found that not only did a study involving volunteers injected with influenza have more fever and illness in the winter, but that children with vitamin D deficiencies had higher rates of viral respiratory infections.
I was not only amazed by vitamin D’s ability to stop influenza in its tracks, but in my resulting research I found scientific links between high vitamin D levels and the prevention of many other illnesses and conditions, including autoimmune diseases; type 1 diabetes (which many researchers believe to be an autoimmune disease); insulin resistance including prediabetes and type 2 diabetes (also associated with obesity); neuromuscular issues including muscle weakness, a reduction in falls of elderly patients (one study found a 20% reduction and another found a 72% reduction in falls), idiopathic low back pain, and fibromyalgia; multiple sclerosis and rheumatoid arthritis (40% reductions in the risks of developing either with supplementation of vitamin D); as well as a possible protective effective in cardiovascular disease by lowering systolic blood pressure and heart rate; and cancer (by inducing cell death in some kinds of cancer cells, including breast, colon, ovarian, and prostate cancers).
Obviously, I had largely underestimated the importance of vitamin D supplementation. It is found in animal based foods like eggs, salmon and other seafood including cod liver oil, beef liver, and cheese; but since the researchers are showing that we need 9,000 IU/day, food sources are not enough. I now buy 5,000 IU gel caps, and recommend taking enough that your levels are close to 100 nmol/L, when tested by your doctor, especially in the winter months.
