Vitamin D 3 and D 2 are both effective for vitamin D repletion, depending on the dosing regimen however, D 3 is more potent.Īcute respiratory infections (cold, flu, chest infections): In an individual patient data meta-analysis evaluating potential of vitamin D 3 supplementation to reduce risk of acute respiratory infections in individuals 0 to 95 years of age, age-appropriate daily or weekly vitamin D 3 supplementation without additional bolus doses was suggested to protect against acute respiratory infections, particularly in those with low baseline 25-hydroxyvitamin D (25D) levels (less than 25 nmol/L).Įlderly: A study conducted to establish the vitamin D requirements in adults 64 years of age and older during the winter determined a recommended dose between 7.9 and 42.8 mcg daily to maintain a serum 25(OH)D level of 25 ng/mL an evidence-based review recommends 800 to 1,000 units/day of vitamin D to reduce the risk of falls in older populations. Vitamin D 3 20 mcg is equivalent to 800 units. Use of higher doses has also been suggested to reduce the risk of falls in older populations.

Data also support use in women with polycystic ovary syndrome (PCOS). Vitamin D supplementation is used for treatment of vitamin D−deficient states in adults and children that can occur due to insufficient dietary sources, insufficient sunshine, increased age, and weight loss surgery.
