How to manage a vitamin D level of 28.2 ng/mL?

From the Guidelines

To manage a vitamin D level of 28.2 ng/mL, you should take a vitamin D supplement of 1,000-2,000 IU daily to reach the optimal range of 30-50 ng/mL. According to the most recent and highest quality study 1, for faster improvement, you could start with a higher dose of 2,000-4,000 IU daily for 8-12 weeks, then reduce to a maintenance dose of 1,000-2,000 IU daily.

Key Considerations

• Choose vitamin D3 (cholecalciferol) supplements as they're more effective than vitamin D2 1.
• Take supplements with a meal containing some fat to improve absorption.
• Additionally, increase your sun exposure (15-30 minutes several times weekly) and consume vitamin D-rich foods like fatty fish, egg yolks, and fortified dairy products.
• Retest your vitamin D levels after 3-4 months to ensure improvement.

Importance of Vitamin D

Vitamin D is crucial for calcium absorption, bone health, immune function, and mood regulation, and insufficient levels can lead to various health issues including bone weakening and increased susceptibility to infections.

Dosage and Administration

The recommended daily allowance for vitamin D in individuals over 60 years is 800 IU, and for younger adults 400 IU 1. However, for individuals with vitamin D insufficiency, a higher dose may be necessary, as recommended by 1.

Monitoring and Maintenance

It is essential to monitor vitamin D levels regularly and adjust the supplementation regimen as needed to maintain optimal levels. According to 1, once-daily administration of 200 to 1,000 IU can help maintain vitamin D homeostasis after repletion has been accomplished.

From the FDA Drug Label

Vitamin D3 50,000 IU is essential for absorption of calcium and necessary for healthy bones and a healthy immune system. DIRECTIONS: Take 0ne (1) capsule each week, or as directed by your physician. The patient's vitamin D level is 28.2 ng/mL, which is considered insufficient.

• The recommended treatment is to take one capsule of Vitamin D3 (50,000 IU) per week, or as directed by a physician.
• It is essential to take the capsule with food and store it in a cool, dry place, protected from light 2.

From the Research

Managing Vitamin D Levels

To manage a vitamin D level of 28.2 ng/mL, consider the following steps:

• The current vitamin D level is considered insufficient, as it falls below the desirable range of at least 30 ng/mL 3, 4.
• Increasing vitamin D intake through supplements or diet may help raise serum concentrations to the desirable range.
• The recommended daily intake of vitamin D varies, but studies suggest that 700-1000 IU per day may be necessary for optimal musculoskeletal health 5, 4.

Supplementation and Diet

Consider the following:

• Vitamin D supplementation should be at least 700-1000 IU per day to cover the needs for both fall and fracture prevention 4.
• Taking vitamin D with the largest meal of the day may improve absorption and increase serum levels of 25-hydroxyvitamin D by about 50% 6.
• Dietary sources of vitamin D, such as fatty fish, egg yolks, and fortified dairy products, may also contribute to increased vitamin D levels.

Monitoring and Maintenance

• Regular monitoring of vitamin D levels is necessary to ensure that supplementation is effective and to adjust dosages as needed.
• Maintenance dosages of cholecalciferol (vitamin D3) at 800-1000 IU per day may be necessary to maintain desirable vitamin D levels 3.
