Vitamin D is essential for healthy bones, as you may well know, but its benefits go beyond bone health.
Because our bodies can create it when exposed to sunlight, vitamin D is sometimes referred to as the "sunshine vitamin." It is essential for preserving general health. Its main job is to make it easier for calcium to be absorbed, which is necessary for bone formation and repair.
However, vitamin D's advantages extend beyond bone health. In addition, it might help control blood pressure, boost immunity, assist in controlling weight, and more. The following list of ten main advantages of vitamin D includes suggestions for how to include it in your regular diet:
1. Strengthens Bones
Vitamin D works alongside calcium to build and fortify bones, thus preventing conditions like osteoporosis, characterized by weak and brittle bones.
2. Supports the Immune System
Research suggests that vitamin D supplementation can enhance immunity, particularly in individuals deficient in this vitamin. Studies have shown a reduced risk of acute respiratory infections with regular vitamin D intake, especially in regions with limited sunlight exposure during winter.
3. Supports Muscle Strength
In addition to its role in bone health, vitamin D also plays a role in strengthening muscles. It aids in the development and growth of muscle fibers, contributing to better balance and reduced risk of falls by supporting bone health.
4. Benefits Oral Health
While research on the relationship between vitamin D and oral health is limited, some evidence suggests that vitamin D’s ability to enhance calcium absorption may help lower the risk of cavities, tooth decay, and gum disease.
5. Potential Diabetes Prevention
Although studies are ongoing, there is some indication that vitamin D supplementation may contribute to the prevention of both type 1 and type 2 diabetes.
One study observed improved insulin sensitivity after six months of vitamin D supplementation among individuals with diabetes or at high risk for the disease.
6. Alleviates Irritable Bowel Syndrome (IBS) Symptoms
Vitamin D might be beneficial for individuals with IBS, as deficiencies in this vitamin are common among them. Some research suggests that vitamin D supplementation could lead to milder IBS symptoms, possibly due to its anti-inflammatory properties.
However, the relationship between vitamin D intake and symptom improvement in IBS is complex and not fully understood.
7. Supports Mental Health
Just as sunlight can lift your spirits, so can vitamin D. Research suggests a connection between depression and vitamin D deficiency, though further studies are needed to fully understand this relationship—whether low vitamin D levels contribute to depression or vice versa.
Nevertheless, experts recommend screening for vitamin D deficiency in individuals with depression, as addressing this deficiency may help improve outcomes.
8. Reduces Multiple Sclerosis Risk
Adequate vitamin D intake may lower the risk of developing multiple sclerosis (MS), an autoimmune disorder affecting the central nervous system. Lower levels of vitamin D have been associated with increased MS risk, while higher intake may reduce disease activity and relapse rates.
9. Reduces Pregnancy Complications
Maintaining sufficient vitamin D levels during pregnancy is important, as deficiency has been linked to various complications such as gestational diabetes, preeclampsia, and pre-term birth.
10. Prevents Rickets in Children
Vitamin D plays a crucial role in children’s bone health, with deficiency increasing the risk of rickets—a condition characterized by softening of bones, especially in children under two years old.
It’s recommended that infants receive 400 international units (IU) of vitamin D daily until they reach 12 months, followed by 600 IU thereafter.
Recommended Vitamin D Intake
- – Adults aged 19 to 70: 15 micrograms (mcg) or 600 IU
- – Pregnant and lactating individuals: 15mcg or 600 IU
- – Adults aged 70 and above: 20mcg or 800 IU
Vitamin D Deficiency
About 25% of Americans have insufficient vitamin D levels, which can result from various factors including inadequate dietary intake and conditions affecting absorption. Deficiency may lead to bone density loss, pain, rickets, and weakened bones or muscles.
