400 Years Old hair tested for Vit D

Recent Document about tests on a 400-year-old strand of hair, unlocks new thinking on Vitamin D and Scotland’s weak winter sun. It discusses the relationship between vitamin D levels and Scotland's weak winter sun.

New findings on the links between Scotland's low winter sun and falling Vitamin D levels have been made using a 400-year-old strand of hair. Researchers compared vitamin D levels in the hair of volunteers who have been living in the Aberdeen area for at least two-and-a-half years to the hair taken from the person buried in the 16th or 17th century.

Sunlight, Vitamin D, and Your Health

Vitamin D is a fat-soluble vitamin that plays a crucial role in numerous bodily functions. It is synthesized by the body when exposed to sunlight and is also found in certain foods and supplements. Vitamin D deficiency is a common problem, particularly in individuals with limited sun exposure, such as those living in regions with high latitudes or those who spend most of their time indoors.

The Importance of Vitamin D

Vitamin D is essential for calcium and phosphorus absorption, which are crucial for building and maintaining strong bones. It also plays a role in regulating the immune system, cell growth, and blood sugar levels. Adequate vitamin D levels are associated with a reduced risk of various health conditions, including osteoporosis, type 2 diabetes, certain types of cancer, and autoimmune diseases.

Sources of Vitamin D

The best natural source of vitamin D is sun exposure. The body produces vitamin D when exposed to sunlight, specifically ultraviolet B (UVB) radiation. The amount of time needed for sun exposure to produce adequate vitamin D varies depending on factors such aas age, skin color, time of day, season, and geographic location.

Dietary sources of vitamin D include fatty fish, such as salmon, tuna, and mackerel, egg yolks, fortified dairy products, and fortified cereals. However, relying solely on dietary sources may not be sufficient to meet vitamin D needs, especially for individuals with limited sun exposure.

Vitamin D Deficiency

Symptoms of vitamin D deficiency can include fatigue, muscle weakness, bone pain, and mood changes. In severe cases, deficiency can lead to rickets in children and osteoporosis in adults. However new studies indicate a much broader relation between health, chronic diseases, immune system and vit D.

Risk Factors for Vitamin D Deficiency

Several factors can increase the risk of vitamin D deficiency, including:

Limited sun exposure: People who live in regions with high latitudes or spend most of their time indoors have a higher risk of deficiency.

Darker skin: People with darker skin have more melanin, which blocks UVB radiation and reduces vitamin D production.

Aging: The ability of the skin to produce vitamin D decreases with age.

Obesity: Excess body fat can interfere with the absorption of vitamin D.

Certain medical conditions: Certain medical conditions, such as kidney disease and inflammatory bowel disease, can impair the body's ability to absorb or produce vitamin D.

Medications: Some medications, such as corticosteroids and anticonvulsants, can interact with vitamin D and increase the risk of deficiency.

Diagnosis and Treatment of Vitamin D Deficiency

Vitamin D deficiency is diagnosed through a simple blood test that measures the level of vitamin D in the blood. Treatment for vitamin D deficiency typically involves vitamin D supplementation. The recommended dosage of vitamin D will vary depending on the severity of the deficiency and individual factors.

Please note that blood test to determine levels of vit D in blood, are not conclusive because do not tell informations about how the body system utilise or convert vitamin D supplements.

Preventing Vitamin D Deficiency

There are several ways to prevent vitamin D deficiency:

Get regular sun exposure: Aim for 15-30 minutes of sun exposure on most days of the week, with your arms and legs uncovered. However, avoid excessive sun exposure, which can increase the risk of skin cancer.

Include vitamin D-rich foods in your diet: Consume fatty fish, egg yolks, fortified dairy products, and fortified cereals.

Consider taking a vitamin D supplement: If you are at risk of deficiency, your doctor may recommend a vitamin D supplement.

Dr. David Grimes studies and recommendations

If you want to understand more about Vit D, Dr. David Grimes, Consultant Physician, medical researcher and author, conducted original researchoonVitam8in D and how it is essential to life.

His studies show widespread vitamin D deficiency and its link to multiple diseases.

During the 1980s he began measuring vitamin D in ~5,000 patients to find that up to 85% of white patients and 95% of South Asian patients severely deficient.

Tuberculosis and link to low Vitamin D.

TB risk soared in the South Asian community 6–8 years after arriving in the UK, likely triggered by lack of sunlight (vitamin D).

Vitamin D supports T-cell function (cellular immunity), helping contain TB bacteria.

Historical Insights on Rickets and TB

Historical data from Glasgow, early 1900s, showed rickets (vitamin D deficiency) and TB clustered in poor, indoor workers. In contrast data from 1926 8n Bombay, showed rickets and TB to be more prevalent amongst
wealthier families that mostly stayed indoors, whereas poorer families working outdoors where less if not affected.

Broader Disease Links (Renal Disease, Diabetes, Heart Disease)

Low vitamin D could be the trigger to chronic diseases like chronic kidney disease, neurological diseases, chronic inflammation and autoimmune conditions, thyroid functions, could also be a reason for worse outcome in viral infections such as covid and recovery post major operations.

Cardiac disease (atherosclerosis, coronary artery disease) may involve chronic infection/inflammation, where vitamin D is crucial to immunity.

There could be a link between type 2 diabetes and low vitamin D, possibly due to effects on insulin resistance.

The general ufficial health recommendation on normal levels of vit D is not adequate, notes that individuals vary widely in how much vitamin D they need taking into account multiple factors such as weight, age, skin color, overal health, sunlight exposure, medications, etc.

Different types of Vit D supplements are Methabolised differently, it takes 2 weeks to build up with common vit D supplements, however Calcifidiol is the form that is activated and absorbed within 2 hours, it's action is faster than antibiotics including IV antibiotics that takes 4 to 8 hours to work, and should be included in treatment of infections including sepsis. This is based on Dr. David Grimes studies and experience in treating his patients.

It is important to check vitamin D levels prior to any operations to support a positive outcome, prevent complications and support recovery.

Common vit D supplements are mostly a form of vegetable oil and small amount of vit D that is in a raw form.

Dr. Anderson stated that prior to any vaccination, one should check vitamin D levels, any vaccination deplete reserve of vitamin D.

Anderson: Retired Consultant Physician and Clinical Endocrinologist and former Professor of Medicine and Endocrinology, University of Manchester, Manchester, UK, and The Chinese University of Hong Kong. He is the author and Dr. David Grimes is co-author of the book "Vitamin D Deficiency and Covid-19: Its Central Role in a World Pandemic.
