Why Should We Take Vitamin D ?
As today is World Statistic Day, find out why Vitamin D is so important for your health.
Did you know that Vitamin D supplementation lowers the risk of respiratory infections by 12–75%. (1) Research also suggests that in addition to a healthy diet and regular exercise, supplements and vitamins can reduce the risk of viral infections. Taking multivitamin benefits people of all ages, and reduces the risk of virus-related respiratory infections, whether they have a chronic illness or not.
Are people hit by COVID-19 more likely to lack Vitamin D?
We have been told again that the public need to take vitamin D supplements, especially during the winter months.
More recently, several studies have identified vitamin D deficiency as a risk factor for COVID-19.
Vitamin tablets have been used in a number of countries to help coronavirus patients but new research supports the claim that vitamin D and coronavirus are linked. The use of vitamin D has risen by 8% in the last 12 months, according to the results of Mintels recent usage survey, this makes it the fastest-growing vitamin in the supplements market (2).
Why is Vitamin D so important?
Vitamin D is vital for a huge number of functions in the body, from supporting your immune system to maintaining strong and healthy bones. Most of your body’s vitamin D comes from getting enough sunlight on your skin. For many people, this is a challenge, which is why new Government guidelines recommend a daily vitamin D3 supplement.
During the winter months when you can be feeling under the weather vitamin D has been shown to help support your immune system, which is essential in fighting off bugs.
Deficient in Vitamin D?
The UK has one of the highest levels of vitamin D deficiency across Europe, estimated to affect up to 1 in 4 of the population rising to 1 in 3 in winter. As well as in the elderly, vitamin D deficiency has been found to occur more frequently in those with obesity and diabetes (3). Studies have also identified that the BAME population, who were particularly affected by COVID-19, are a risk group for vitamin D deficiency (4).
What’s the latest evidence?
The latest study by Boston University found:
People with vitamin D deficiency have a 54% higher COVID-19 positivity rate. Patients over the age of 40 who had sufficient levels of vitamin D were more 51% less likely to die from the virus. (5)
Patients who had a daily dose of vitamin D were less likely to experience health complications. Due to the highly publicised research linking vitamin D with protection against COVID-19, we have noticed an increased demand in vitamin D3 supplements.
Are YOU getting enough Vitamin D?
Your body must have vitamin D to absorb calcium and promote bone growth. You also need vitamin D for other important factors, such as helping to fight against diseases, reducing depression and boosting weight loss.
How much Vitamin D should you take does depend on many factors, such as, age, race, season and sun exposure. Recommendations from The Institute of Medicine suggest that an average intake of 400-800 IU or 10-20 micrograms, is adequate for 97.5 of individuals (6).
How does Vitamin D help flight diseases?
Vitamin D has shown to boost our immune systems so that it stays balanced especially during the winter months when people are prone to colds and flu.
There are Vitamin D receptors and activating enzymes on the surface of all white blood cells. The role that vitamin D plays in keeping the immune system healthy is quite complex because the immune system must be perfectly balanced. If there is too much stimulation, autoimmune diseases can set in. If there is not enough immune system activity, frequent infections can occur.
How does Vitamin D reduce depression?
Depression is one of the leading causes of disability worldwide and a major contributor to suicide and coronary heart disease (7)
Vitamin D is important for brain function and for neurotransmitters like serotonin and dopamine, which play a role in mental health. A deficiency in vitamin D can upset the healthy balance of these brain chemicals, thereby increasing the risk of brain disorders like anxiety and depression.
Studies have shown a link between vitamin D deficiency and depression. Researchers behind a 2013 meta-analysis noticed that study participants with depression also had low vitamin D levels. The same analysis found that, statistically, people with low vitamin D were at a much greater risk of depression. (8)
How does Vitamin D boost weight loss?
Vitamin D plays a vital role in weight loss. If you’re not losing weight despite exercising regularly, getting plenty of sleep, and eating healthy foods, it’s possible you’re not getting enough vitamin D.
The hypothalamus, which helps regulate your hormones, tells your body whether it should store or release fat depending on your level of vitamin D. If you don’t have enough vitamin D, the hypothalamus tells your body to hold on to fat storage. If you’re getting plenty of vitamin D, the hypothalamus tells your cells to burn fat.
When you’re not getting enough sunshine, your body interprets this as the onset of winter. Just like animals that hibernate, humans have been programmed to hold on to their fat storage in anticipation of food shortage when there is less daylight. Lack of vitamin D tells the brain it’s time to start hoarding fat.
