Frequently asked questions

Why is vitamin D important for health?
Vitamin D is essential for many vital body functions, including immune, bone, and muscle health. It is a fat-soluble vitamin that can be obtained from food and supplements and is also produced by the skin when exposed to sunlight. According to the World Health Organization (WHO), nearly a billion people worldwide are deficient in vitamin D. Vitamin D regulates calcium and phosphorus absorption, which are important for strong bones and teeth, supports cardiovascular health, cell division, the immune system, and helps regulate mood.

How is liposomal vitamin D different from regular vitamin D?
Liposomal vitamin D is a special supplement form that uses liposomes—small phospholipid bubbles—to improve vitamin D absorption. These liposomes act as a protective carrier, helping vitamin D to be absorbed more effectively and reach the body’s cells. Regular vitamin D supplements, like tablets or capsules, may not absorb as efficiently as they lack this protective mechanism.

What is the difference between vitamins D2 and D3?
Vitamin D consists of fat-soluble compounds that support various body functions, such as bones, immunity, and mineral balance. D2 (ergocalciferol) and D3 (cholecalciferol) are the two main forms.

• Vitamin D2 comes from plant sources, such as mushrooms treated with UV light.
• Vitamin D3 is mainly of animal origin, found in fatty fish, and is produced in the skin upon sun exposure.Can vitamin D levels fluctuate with the seasons?
  Yes, vitamin D levels can vary seasonally due to changes in sunlight intensity. In summer, vitamin D production in the skin is higher, while in winter, when sunlight is weaker, levels can drop, especially in regions farther from the equator.

How does the body produce vitamin D?
Vitamin D is naturally produced in the skin through exposure to the sun’s UVB rays. However, the body has a limit on how much vitamin D it can produce from sunlight—excessive sun exposure doesn’t increase vitamin D production but may increase the risk of skin cancer.

What is bioavailability, and why is it important?
Bioavailability refers to how effectively the body absorbs and uses a vitamin or nutrient. Nutrients with higher bioavailability absorb better and are more usable by the body, while nutrients with low bioavailability may require larger doses to achieve the same effect.

How does liposomal technology improve vitamin D absorption?
Liposomal technology enhances vitamin D absorption by encasing it in a fat-based shell called a liposome. This protects the vitamin from early breakdown during digestion and helps deliver it to cells.

For which medical conditions might liposomal vitamin D be beneficial?
Liposomal vitamin D is often used to support conditions associated with vitamin D deficiency, such as osteoporosis, immune system strengthening, muscle health, and mood disorders.

How should vitamin D be stored?
Liposomal vitamin D should be kept in a cool, dry place, below 25°C, protected from direct sunlight and heat.

When should you test your vitamin D levels?
It’s important to consult your doctor if you’re concerned about your vitamin D levels. Your doctor may suggest testing in the following situations:

• You’re taking vitamin D supplements and want to monitor your progress (usually after 3 months).
• You’ve been diagnosed with conditions like osteoporosis or osteomalacia.
• You have an absorption disorder, such as celiac disease.
• You spend extended periods indoors, limiting sun exposure.
• You’re taking medications known to reduce vitamin D absorption (e.g., anti-seizure drugs).
• You have symptoms potentially related to vitamin D deficiency, and your doctor wants additional diagnostics.
