VITAMIN D

• Vitamin D can fight disease
In addition to its main benefits, research suggests that vitamin D may also play a role in:
Reduce the risk of multiple sclerosis (MS). A 2018 review of population-based studies found that low vitamin D levels are linked to an increased risk of MS (Sintzel et al., 2018)
Decrease the risk of heart disease. Low levels of vitamin D have been linked to an increased risk of heart diseases such as hypertension, heart failure and stroke.
But it’s unclear whether vitamin D deficiency contributes to heart disease or is just a sign of poor health when you have a chronic condition (Saponaro et al., 2019)
Reduce the likelihood of serious illnesses. Although studies are mixed, vitamin D may make serious flu and COVID-19 infections less likely. A recent study found that low vitamin D levels contribute to acute respiratory distress syndrome (Chen et al., 2021; Grant et al., 2020).
Immune health support. People who lack adequate levels of vitamin D may have an increased risk of infections and autoimmune diseases, such as rheumatoid arthritis, type 1 diabetes, and inflammatory bowel disease (Martens et al ., 2020)

• Vitamin D may regulate mood and reduce depression
Research has shown that vitamin D may play an important role in regulating mood and reducing the risk of depression. A study in 7,534 people found that people experiencing negative emotions and receiving vitamin D supplements saw improvements in their symptoms. Vitamin D supplementation may help people with depression who also have vitamin D deficiency (Cheng et al., 2020)
Another study identified low vitamin D levels as a risk factor for more severe fibromyalgia symptoms, anxiety, and depression (D’Souza et al., 2020)
• It may promote weight loss
People with high body weight are more likely to have low vitamin D levels (Lotfi-Dizaji et al., 2019)
In one study, obese people who took vitamin D supplements in addition to their diet lost more weight and fat than members of the placebo group who ate only their diet. (Lotfi-Dizaji et al., 2019)
In an older study, people taking daily calcium and vitamin D supplements lost more weight than subjects taking a placebo supplement. The researchers suggest that the calcium and vitamin D supplement may have had an appetite suppressing effect (Major et al., 2008).
Current research does not support the claim that vitamin D causes weight loss, but there does appear to be a relationship between vitamin D and weight.
