Product Information

Though both vitamin D2 and vitamin D3 can increase blood levels of vitamin D, some research suggests that vitamin D3 is more effective ( 7). Your vitamin D needs depend on a variety of factors. These include your age, skin color, current blood vitamin D levels, location, sun exposure, and more ( 17). For adults under the age of 70, the daily recommended amount of vitamins D is 600 IU, while older adults can get 800 IU. The safe upper limit is 4,000 IU per day, however, it has not been shown to cause toxicity. What measure is UG in vitamins? A vitamin D deficiency can only be discovered through blood tests that measure levels of storage vitamin D, known as 25(OH)D. Evolving recommendations for vitamin D illustrate the need to assess serum biomarkers from an optimal perspective. Evaluation of both optimal vitamin D levels and intake have been gaining attention.

Since everyone absorbs vitamin D differently, the 25(OH)D value may develop differently. This means that not ever person will achieve exactly the same 25(OH)D level in their blood even if they take the same dose of vitamin D. Some people have medical conditions that mean they may not be able to safely take as much. If in doubt, you should consult your doctor. If it’s a naturally-sourced vitamin E, you will see it called “d-alpha.” If you see “d-alpha” on the label, just multiply the IU by 0.67. For example: Here you'll find dosage recommendations for the intake of vitamin D in form of a dietary supplement, depending on the respective 25(OH)D value. The recommendations are based on the findings of Dr. John J. Cannell, a vitamin D expert and founder of the Vitamin D Council organization. This is because they have more melanin in their skin — a pigment that helps determine skin color. Melanin helps protect the skin from the sun’s UV rays ( 41).The conversion is really easy. Just divide the amount of mcg folic acid by 0.6 and you will see the amount of folate mcg DFE you have. For example:

It’s a good idea to take 100 to 4,000 IU of vitamins D and D2 a day. This applies to people of all ages, including pregnant and breastfeeding women. Children between the ages of 1 and 10 should not have more than 500 IU a day. Is 25 vitamin D enough? The Vitamin D Council considers these levels to be 'normal to high'. These vitamin D levels can be achieved by exposing the skin to adequate sunlight. As a result, it is assumed that these are natural, healthy levels. Your value is between 80 - 100 ng/ml Though more research is needed, it seems that consuming 1,000–4,000 IU (25–100 mcg) of vitamin D daily should be ideal for most people to reach healthy vitamin D blood levels ( 14). Deficient: levels less than 12 nanograms per milliliter (ng/mL), or 30 nanomoles per liter (nmol/L)
