Vitamin D - the "sunshine vitamin"
Vitamin D is a critical nutrient and hormone essential for several bodily functions. While its primary role is bone health, emerging research continues to explore its impact on the immune system, mood, and chronic disease prevention.
And here is the best bit - Vitamin D treatments are available here at City Way.
Core Health Benefits
Bone and Dental Health: Vitamin D is vital for absorbing calcium and phosphorus from the diet. Without it, only 10–15% of dietary calcium is absorbed, leading to thin, brittle, or misshapen bones. It prevents rickets in children and osteomalacia or osteoporosis in adults.
Muscle Function: It supports muscle strength and development. Adequate levels are linked to better balance and a reduced risk of falls, particularly in older adults.
Immune System Support: Vitamin D helps the immune system fight off bacteria and viruses. It reduces inflammation and may lower the risk of autoimmune diseases like rheumatoid arthritis, lupus, and multiple sclerosis.
Mental Health and Energy: Low levels are strongly associated with fatigue and low mood, including seasonal affective disorder (SAD) and depression. Some studies suggest supplementation can improve energy levels and mood in those who are deficient.
Emerging Research and Potential Benefits
Disease Prevention: Higher vitamin D levels are associated with a reduced risk of certain cancers (especially colorectal), heart disease, and type 2 diabetes. A 2026 report suggests it may even slow biological aging by protecting telomeres.
Skin Health: It supports skin cell growth, repair, and metabolism. It is used topically or orally to treat conditions like psoriasis and may reduce the severity of eczema.
Cognitive Health: Research shows a link between low vitamin D and cognitive decline, including an increased risk of Alzheimer’s and dementia.
