Unlocking the secrets of Vitamin D is one area of health research that continues to uncover new surprises. From childhood through adulthood, having a healthy level of this powerful vitamin in our systems has huge implications for living healthier and better lives. Recent findings show us that it doesn't just absorb calcium from food - its receptors can be linked throughout every tissue within our bodies! Who knows what else we'll find as research progresses?

The importance of vitamin D in our health cannot be overstated. Not only is it integral to maintaining strong bones, but research now indicates that immune cells have receptors for the nutrient! This discovery implies that having adequate vitamin D levels can help activate these essential components of immunity and support overall cardiovascular system health.

Recent studies have made it clear that, despite the benefits of direct sunlight exposure on skin to provide vitamin D, many people are unable obtain sufficient levels without taking additional measures. For those whose body struggles with this conversion or needs more than what can be naturally produced, a high-quality supplement is an effective and healthful solution for maintaining optimal well-being.

To ensure your body is properly metabolizing vitamin D, opt for the more bioavailable form - D3. Make sure that whatever source you choose offers at least 5,000 IU of this vital nutrient from a natural resource and not something synthetic or artificial. Beware products with unfavorable additives like magnesium stearate which may be potentially harmful to consume!

  • Question:
    I do not see an expiration date on the bottle. If stored properly, how long after bottle is opened does it expire?
    Michelle on 10/04/2017 Answer:
    • Hi Michelle, thank you for your question. The product does have a manufacture date rather than an expiration date. The manufacture date the product currently has is 04/17/2017. The expiration date is 3 years after the manufacturing date so the expiration date will be 04/17/2020. Hope this helps! Have a happy and healthy day!
