Psoriasis is a chronic autoimmune disorder that results in the rapid buildup of skin cells, forming thick, red, scaly patches that can be itchy and painful. Affecting over 7.5 million Americans, it is associated with significant healthcare costs, with estimates reaching $112 billion annually in 2013.
In this condition, T cells—a type of white blood cell—mistakenly attack healthy skin cells. This immune overreaction triggers a rapid skin cell turnover, causing new cells to move to the surface of the skin at an accelerated rate. The result? Dead cells accumulate, forming those characteristic scaly patches that can crack and bleed.
People with psoriasis are also at a higher risk of developing other serious conditions like heart disease, type 2 diabetes, high blood pressure, and eye problems. Mental health issues such as depression, low self-esteem, and social isolation are also common.
The Missing Vitamin: Why Vitamin D Matters
One often-overlooked factor in managing psoriasis is vitamin D. This crucial nutrient acts as an immune system modulator, helping to prevent autoimmune diseases like psoriasis. It plays a significant role in skin health by regulating the growth of skin cells (keratinocytes) and modulating the immune response of T cells. Vitamin D inhibits the activation of cytotoxic T cells and helps to control skin cell growth.
Although traditional treatments for psoriasis are often expensive and come with risks, optimizing vitamin D levels through proper sun exposure is a natural and effective way to manage the condition. According to Dr. Michael Holick, a dermatologist and expert in vitamin D research, exposure to sunlight’s UV rays helps by reducing the overactive T cells in the skin, slowing down cell turnover, and alleviating inflammation.
Psoriasis and Parkinson’s: An Unexpected Link
Research also suggests a connection between psoriasis and an increased risk of Parkinson’s disease. A study found that lower levels of vitamin D, whether from diet or lack of sun exposure, are linked to a higher risk of developing Parkinson’s. This finding highlights the broader implications of vitamin D deficiency beyond skin health.
Vitamin D’s Broader Impact on Health
Increased vitamin D levels have also been linked to improved survival rates in individuals with advanced colorectal cancer. A study by Joan Lappe and Robert Heaney in 2007 demonstrated that higher vitamin D levels led to a 77% reduction in cancer risk among menopausal women.

Research shows that vitamin D may also help lower the risk of multiple sclerosis, reduce the chances of developing heart disease, and even aid in preventing the flu. Furthermore, studies have found that vitamin D plays a vital role in regulating mood and combating depression, particularly in individuals who are overweight.
The Power of Vitamin D in Disease Prevention
Vitamin D interacts with DNA through specific receptors, influencing numerous genes related to disease prevention. According to Dr. Mercola, this vitamin plays a crucial role in preventing diseases such as cancer, type 2 diabetes, and Alzheimer’s. Optimizing vitamin D levels can reduce the risk of various cancers, including pancreatic, lung, ovarian, and skin cancers, by enhancing the body’s ability to destroy mutated cells and slow down cancer cell growth.
In addition to its cancer-fighting properties, vitamin D has been found to reduce the risk of chronic inflammation, age-related blindness (macular degeneration), and even tuberculosis, pneumonia, colds, and flu.
Optimizing Your Vitamin D Levels
To support overall health, vitamin D levels should range between 50-70 ng/ml. For individuals battling chronic conditions like psoriasis, heart disease, or cancer, levels should ideally fall between 70-100 ng/ml. Unfortunately, vitamin D deficiency is prevalent worldwide, particularly in men aged 31-60 and women aged 16-30.
The best way to naturally boost vitamin D is through sensible UVB sun exposure. If this isn’t possible, vitamin D3 supplements are a great alternative. When taking supplements, be sure to choose vitamin D3, not the synthetic D2 form. Additionally, combine it with vitamin K2 and magnesium to maximize its benefits. Vitamin D is fat-soluble, so taking it with healthy fats enhances absorption.
The Importance of Vitamin K2 and Magnesium
Vitamin K2 helps direct calcium to the right places in the body, preventing artery calcification. According to Dr. Kate Rheaume-Bleue, vitamin D and K2 work together to strengthen bones and support heart health by ensuring calcium is properly utilized.
Magnesium is equally important, as it converts vitamin D into its active form and helps the body use it effectively. Foods rich in magnesium include sea vegetables like kelp, dulse, and nori. If you opt for supplements, consider magnesium citrate or threonate.

Finally, remember that vitamin D interacts with other nutrients like vitamin A, zinc, and boron, so it’s essential to maintain a well-balanced diet.
