Product Information

From supporting strong and healthy bones to maintaining your immune system, vitamin D is very important for a huge number of functions in the body. When the darker nights arrive, it becomes all the more important as we usually make our vitamin D using sunshine. 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. From about late March/early April to the end of September, the majority of people should be able to make all the vitamin D they need from sunlight on their skin. What’s a DFE you might ask? It’s a “dietary folate equivalent.” This is a unit of measure that’s been developed to better equate the biological effects of the folate found in food compared to the synthetic sources of folate such as folic acid and methylfolate. Synthetic sources are more potent at increasing the folate levels in your body compared to food sources. So the amount of DFE provided by these sources is higher. You may choose not to take a vitamin D supplement during these months. People at risk of vitamin D deficiency

To ensure optimal blood levels in most people, a daily intake of 1,000 to 4,000 IU of vitamins D and D2 should be sufficient. Additionally, your bones become more fragile with age. Maintaining adequate blood levels of vitamin D can help preserve bone mass with age and may protect against fractures ( 8, 38). People with darker skin Added colistimethate sodium (conversion to colistin base or vice versa). This conversion required in the case of inhalation administration of colistimethate sodium. The conversion works either in the direction of [IU of colistimethate sodium in mg/g of colistin base) or in the direction of [mg/g of colistin base in IU of colistimethate sodium]. Endogenous production of vitamin D is stimulated when a cholesterol compound in the skin is exposed to UVB light, with subsequent hydroxylation and activation at the liver and kidney level. From 10000 to 25000 IU of vitamin D can be produced endogenously when exposed to one erythemal dose of UV radiation (leaves a slight pinkness in the skin 24 hours following exposure). Endogenous vitamin D remains in the blood longer than ingested vitamin D.[xvi] Added translations and language selection for Farsi (32%), Italian (29%), Spanish (14%). Thank you guys, who made these translations!Children aged 1 to 10 years should not have more than 50 micrograms (2,000 IU) a day. Infants under 12 months should not have more than 25 micrograms (1,000 IU) a day. When exposed to sunlight, our bodies will naturally make vitamin D3. This process happens when ultraviolet B (UVB) radiation from the sun triggers the 7-dehydrocholesteol to produce D3. Research suggests that everyone over the age of one years should have a daily intake of at least 10µg of Vitamin D per day to protect bone and muscle health. Government advice is that everyone should consider taking a daily vitamin D supplement, especially during the autumn and winter. v] Maghbooli, Zhila et al. “Vitamin D sufficiency, a serum 25-hydroxyvitamin D at least 30 ng/mL reduced risk for adverse clinical outcomes in patients with COVID-19 infection.” PloS one vol. 15,9 e0239799. 25 Sep. 2020, doi:10.1371/journal.pone.0239799

New FDA guidelines require that vitamin D be reported in µg. Manufacturers may also list the IU amount in parentheses following the amount in µg. At this vitamin D level, the body can perfectly regulate calcium absorption via the adequate formation of parathyroid hormone. Breastfeeding mothers can sufficiently pass on vitamin D to their baby through breast milk. Keep in mind that it’s important not to consume more than 4,000 IU of vitamin D without a doctor’s permission, as it exceeds the safe upper limits of intake and is not linked to additional health benefits ( 14). summaryOn the other hand, IU measures something less obviously tangible, such as a product's biological activity or potency. You should not exceed the recommended dose of 1 supplement per day. This level of intake is designed to meet the needs of your body. It’s not a good idea to take more at the moment. Is 12.5 ug vitamin D enough? This value indicates severe vitamin D deficiency and represents significant risk to health. This low vitamin D level means that calcium cannot be sufficiently absorbed into the blood, which may lead to osteomalacia. This may also affect muscle strength and motor coordination. Since vitamin D is potentially toxic, the state-approved limit is 50 mcg (2.000 IU). However, this is a conservative limit and is likely 5 times too low. The most common form of vitamin E is the “dl-alpha tocopherol” form. If you see this form, you just multiply the IU by 0.45. For example:
