“To our knowledge, this is the first study comparing vitamin D3 and D2 [blood levels] from the summertime peak through to the wintertime,” researchers wrote in the British Journal of Nutrition.
Led by Victoria Logan, researchers studied 95 people, ages 18 to 50, in a randomized trial. Participants were divided into 3 equal groups: the first group received a placebo, and the second and third groups received 1,000 IU daily doses of vitamin D2 or D3 for 25 weeks starting at the end of summer.
Results showed that vitamin D3 levels decreased as a result of D2 supplementation, whereas D3 levels were maintained in the D3 supplementation group.
Other Research Studies
Several studies have reported that the D3 form of the vitamin is more potent than D2, with a study led by Robert Heaney, MD, from Creighton University in Nebraska reporting that D3 was 87% more potent than D2 (Journal of Clinical Endocrinology & Metabolism, doi: 10.1210/jc.2010-2230).
The first-ever systematic review and meta-analysis comparing the effectiveness of the vitamin D forms also recently concluded that D3 was better than D2 (American Journal of Clinical Nutrition, doi:10.3945/ajcn.111.031070).
The new study by the University of Otago in New Zealand found that 1,000 IU of vitamin D3 maintained 25(OH)D levels during the winter months, whereas 25(OH)D levels decreased with the same dose of vitamin D2.
What are the Health Benefits of Vitamin D?
Vitamin D is a vital nutrient your body requires to maintain good health. The benefits of vitamin D reach far beyond simply maintaining strong bones. Here are some of the major vitamin D3 benefits and why it’s important you get enough vitamin D from the sun, the foods you eat and from supplements:
- Vitamin D helps the intestines absorb nutrients, including calcium and phosphorus. This ensures strong bones and a strong immune system.
- Vitamin D helps to lower the risk of osteomalacia and rickets. Osteomalacia, which causes weakness of the muscular system and brittle bones, is most prevalent among adults with a vitamin D deficiency. Rickets is a skeletal deformity mostly seen in children with a vitamin D deficiency.
- Vitamin D provides calcium balance in the body that helps lower the risk of osteoporosis or arthritis.
- Vitamin D helps to regulate blood pressure, reduce stress and tension, relieve body aches and pains by reducing muscle spasms, reduce respiratory infections, helps in differentiation of the cells, aids in insulin secretion, helps fight depression, improves overall skin health by reducing wrinkles, makes skin soft, strong, and smooth, and improves cardiovascular strength by providing a protective lining for the blood vessels.
- Vitamin D is recommended in the treatment of several disorders, and it may help lower the risk of developing many serious health conditions.
Take a Supplement to Boost Vitamin D3 Benefits
Most researchers agree that many people are vitamin D deficient and need vitamin D supplements. According to the Vitamin D Council, Vitamin D deficiency is a global epidemic with an estimated one-half of the world population deficient in this vital nutrient.
To ensure you’re getting all the Vitamin D your body needs to maintain your good health, take a supplement, such as Healthy Choice Naturals Vitamin-D Complex. It provides 4000 IU of all natural Vitamin D3 per daily dose, which is a full 1000% of the recommended daily allowance. Plus, it also provides Vitamin D/K-2, Magnesium, Zinc, L-Taurine, Quercetin and Boron.
