D3 5000 by Metagenics features 5‚000 IU of vitamin D3 (the most bioavailable form). This is a high dose vitamin that will quickly replenish vitamin D status in those with deficiencies. Metagenics has created this oil-solubilized vitamin D supplement‚ in easy-to-swallow soft gel capsules‚ for optimal absorption in the digestive tract.
Vitamin D Deficiency
The Recommended Daily Allowance (RDA) was set by the United States government to prevent certain diseases that can be caused by extreme vitamin D deficiency. Rickets and osteomalacia are now very rare‚ but had negative effects on the skeleton and weakened bones.
Much of the population has sub-optimal serum levels of vitamin D; however‚ some groups of people are at greater risk than others. The elderly‚ obese and those who limit unprotected sun exposure are all at risk for vitamin D deficiency‚ as are people with malabsorption syndromes like cystic fibrosis and inflammatory bowel diseases like Crohn’s.
Vitamin D3 vs. D2
There are two types of vitamin D that are important to humans: ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3). D2 is synthesized by plants‚ while D2 is the type that the human body synthesizes from sunlight. Metagenics chose to include vitamin D2 in its supplement because it’s the most easily absorbed and bioavailable source. Vitamin D3 is also more stable‚ so it is likely to remain effective for a longer period of time‚ even when it has been exposed to different temperatures and humidity levels. D3 has also been shown to be more effective at raising and maintaining serum levels of vitamin D‚ making it the better choice for those who are deficient.
Metagenics creates innovative supplements that help people overcome the symptoms of chronic diseases and maintain their health. Quality and research is paramount‚ and has been since the company was founded in 1983. All active ingredients in Metagenics products have been demonstrated effective by third-party scientists.
