2. Vitamin D
Vitamin D is a fat-soluble nutrient that helps your body absorb calcium, magnesium, and other minerals. Your skin makes vitamin D3 through exposure to ultraviolet light, while vitamin D2 comes from food. Both forms are transported to the liver to be metabolized into 25-hydroxy vitamin D, the key marker of vitamin D status. Vitamin D3 supports bone formation, immune balance, and mood, with Vitamin D3 being the most effective supplement.
3. Vitamin D Deficiency
Vitamin D deficiency is a global concern, as nearly every cell in our body needs Vitamin D for proper functioning. Low Vitamin D levels raise the risk of serious conditions, including osteoporosis, heart disease, diabetes, depression, autoimmune disorders, infections, certain cancers, and overall higher mortality.

FAQs
1. Vitamin D Test
How does the Vitamin D test work?
The test measures 25-hydroxy vitamin D levels, the body’s main storage form, to determine overall vitamin D status. A level below 30 ng/mL in case of a positive result indicates Vitamin D deficiency. In such cases, vitamin D supplements may be advised based on clinical evaluation.
When should the test be used?
The 25-hydroxy vitamin D test helps diagnose and monitor rickets, osteomalacia, postmenopausal osteoporosis, and renal bone issues. Low Vitamin D levels are also linked to cancer, cardiovascular and autoimmune disorders, diabetes, and depression. It can be used at any time to assess whether you need a Vitamin D supplement or not.
How to interpret the test if the line colors differ?
Line intensity variations are normal. To interpret the result correctly, compare the T-line colour with the “Vitamin D Color Card” included in the kit. This reference helps determine whether the vitamin D level falls within sufficient, insufficient, or deficient ranges.
If I read the result after 20 minutes, is it reliable?
No. The result must be read exactly at the 10-minute mark after adding the buffer. Interpretation after 20 minutes is considered unreliable because the test reaction may continue to change, potentially giving misleading or invalid results.
If I read the result after 20 minutes, will the result be reliable?
No. The result should be read at 10 minutes after adding the buffer. The result is unreliable after 20 minutes.
2. Vitamin D Drops
What does AOR Vitamin D3 1000 IU do?
These vegan liquid drops provide 1,000 IU of vitamin D3 per serving to support calcium and phosphorus absorption. D3 is rapidly converted to its active form, helping maintain strong bones and a well-regulated immune system. Non-GMO and free of common allergens.
How does vitamin D3 work in the body?
Vitamin D3 increases intestinal absorption of calcium and phosphorus. After ingestion, it’s converted in the liver and kidneys to its active hormone form, which supports bone mineralization and helps modulate immune responses for balanced, everyday wellness.
Do I need testing or medical advice before use?
If you are deficient or unsure of your status, consider a 25-hydroxyvitamin D blood test. Many adults benefit from supplementation, but needs vary. Talk with your healthcare provider, especially if you have medical conditions, take medications, or are pregnant.
How should I store the drops?
Store the unopened bottle in a dry place between 36–86 °F (2–30 °C). Do not freeze. Keep the cap tightly closed and avoid moisture. As with all supplements, keep out of reach of children, and use by the expiry date printed on the package for best potency.
