Vitamin D3 is a fat-soluble vitamin crucial for numerous bodily functions, particularly in children. One of its primary roles is regulating calcium and phosphorus levels in the blood—a balance critical for overall health. Even a 1% imbalance can lead to significant health problems. While several forms exist, Vitamin D3 (cholecalciferol) and D2 (ergocalciferol) are the most vital for humans.
A deficiency can cause rickets (bone deformities), increase fracture risk, and lead to irritability, developmental delays (delayed walking), reduced appetite, delayed teething, and enamel defects. Furthermore, studies link chronic childhood Vitamin D deficiency to an increased risk of developing diabetes, obesity, autoimmune disorders, cancer, cardiovascular disease, psoriasis, atopic diseases, and inflammatory bowel disease later in life.
The body produces Vitamin D when exposed to sunlight. Dietary sources include fatty fish (mackerel, salmon, sardines, tuna – 250-300 IU/100g), egg yolks (20 IU per yolk), and mushrooms (100 IU/100g of fresh mushrooms). However, Vitamin D production is influenced by geographic location, season, time of day, cloud cover, and air pollution. In many regions, sufficient Vitamin D production from sunlight is only possible during summer months. Children need at least 30 minutes of direct sunlight per week without clothing, or 2 hours per week with only face and limbs exposed. People with darker skin produce less Vitamin D due to melanin's absorption of sunlight. Sunscreen with SPF 8 or higher reduces Vitamin D production by 95%.
Children typically obtain 150-250 IU of Vitamin D daily through diet. However, growing children require 5-10 times more. The Russian Pediatric Association recommends prophylactic Vitamin D supplementation for children of all ages to address Vitamin D deficiency, aligning with the national program implemented in 2018. RealCaps Vitamin D3 provides a convenient and effective way to ensure your child receives the necessary daily intake.
