Vitamin D3 can be synthesized by humans in the skin upon exposure to ultraviolet-B (UVB) radiation from sunlight. But, due to the winter season, weather conditions, and sun block, the body’s ability to produce optimal vitamin D levels may be inhibited. These factors point to the value of taking a daily vitamin D supplement.
Benefits at a Glance:
- Supports healthy bone density
- Encourages healthy cell differentiation
- Promotes healthy immune function
- Shown to increase vitamin D blood levels with daily use
- Perfect for those whose multivitamin already contains vitamin D
Supports bones, cellular health, and immune function
Vitamin D has long provided significant support for healthy bone density.1-7 However, scientists have also validated the critical role that vitamin D plays in regulating healthy cell division and differentiation, and its profound effects on human immunity.8-14 These findings link a deficiency of vitamin D to a host of common age-related problems.
Getting enough vitamin D
The current RDA for vitamin D is only 600 IU which has resulted in startling evidence of a widespread deficiency for this vitamin. Most experts in the field now recommend an intake between 1,000–10,000 IU for adults to achieve a serum 25(OH)D level above those indicative of vitamin D deficient levels, at approximately 80 nmol/L or 32 ng/mL.
Life Extension suggests that healthy adults supplement each day with 5,000–8,000 IU of vitamin D with the objective of achieving an optimal 25-hydroxy vitamin D blood level between 50–80 ng/mL. A vitamin D blood test can help you determine the additional amount of vitamin D you may need to supplement with to achieve an optimal level.
Complements multivitamins with vitamin D
If your calcium supplement or multivitamin also contains vitamin D3, this softgel is an excellent way to complement that intake and reach an optimum blood level of D3 for whole-body health!
For decades, Americans have been told to avoid table salt. But when iodized table salt is reduced, people can unknowingly lower their iodine intake to suboptimal levels. Analyses from the National Health and Nutrition Examination Survey (NHANES) show that urinary iodine levels have plummeted since the 1970s.
The good news is that you can avoid iodized table salt without sacrificing the health benefits of iodine. Sea-Iodine is a low-cost proprietary formula that health-conscious individuals can take each day to support optimal iodine levels. Using natural ingredients harvested from a blend of organic marine algae, Sea-Iodine brings you the health of the sea while avoiding the dangers of excessive salt intake. The algae found in Sea-Iodine provide you with over 667% of the Recommended Daily Value of natural iodine.
Iodine is a health-promoting trace element essential for life. Its primary biological role lies in the production of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). T4 and T3 contain four and three atoms of iodine per molecule, respectively. The thyroid gland actively absorbs iodide from the blood to make and release these hormones into the blood.
Iodine happens to be found abundantly in sea vegetables and plants. In areas where no marine foods are eaten, people have lower iodine levels. For this reason, US commercial salt makers have long added iodine to deliver this key ingredient to your diet. However, we now know the concerns associated with eating too much table salt, which resurrects the dilemma of where to get healthy sources of iodine.
Ironically, health-conscious people are often the most likely to develop low iodine levels. One reason is that athletes and people engaged in heavy physical effort deplete their natural stores of this trace mineral through perspiration. Vegetarians also have a substantially greater likelihood of low levels of iodine than carnivorous people, since foods of plant origin are less rich in iodine than animal-derived foods. One study demonstrated iodine deficiency in 25% of vegetarians and an incredible 80% of vegans.
For those who would like the convenience and economy of taking vitamin D along with their Sea-Iodine all in one pill, Life Extension also offers Vitamin D3 with Sea-Iodine.
