D needs K and U need D!


With summer on our heels, the days are getting longer and the sun is shining, which means we’re hopefully building up more of that Vitamin D goodness in our bodies. For those of us who spend any measurable amount of time outdoors, we may be under the impression our Vitamin D levels are more than sufficient. But are they? It’s well known that Vitamin D deficiency is more frequent in certain subgroups, including elderly, dark-skinned, or overweight individuals; nursing home residents; and people residing in areas of low UV exposure at ≥35°North (For reference, the San Francisco Bay Area sits at 37°North). And what about those of us who avoid sun exposure due to sensitivity, autoimmune conditions, or to decrease our risk of developing skin cancer?

Vitamin D has several important functions, the most vital of which are regulation of calcium and phosphorous absorption, and facilitating normal immune system function. This is because Vitamin D is a potent neuroregulatory steroidal hormone that influences nearly 3,000 of your 25,000 genes! Keeping our Vitamin D level at an optimum range (>50-70 ng/ml) is important for normal growth, development and maintenance of healthy bones and teeth, as well as improved resistance against certain diseases such as multiple sclerosis, heart disease, the flu, various types of cancer and even infertility. Most recently, new data from a birth cohort study[1] in Greece has linked maternal vitamin D deficiency in early pregnancy with an increased risk of behavioral issues and attention-deficit/hyperactivity disorder (ADHD)–like symptoms in preschool children.

How can we effectively raise our Vitamin D level to a healthy range, when sunlight exposure isn’t an option or isn’t enough? At Yinfinite Wellness, we abide by the most current research which shows taking a supplement consisting of Vitamin D3 in conjunction with Vitamin K2 is your best bet. Vitamin K2 is present naturally in high quantities in your gut, but is not absorbed from there and passes out in your stool. It is naturally occurring in foods like natto and fermented cheeses, but few of us get enough Vitamin K2 in our diets. It is Vitamin K2 that — when taken with Vitamin D3 — directs calcium to your skeleton, while preventing it from being deposited in your organs, joint spaces, and arteries (a significant percentage of arterial plaque consists of calcium deposits, hence the term “hardening of the arteries.”). In other words, taking Vitamin D3 by itself without the help of Vitamin K2 may actually be working against you!

At Yinfinite Wellness, we carry a high quality, bioavailable form of Vitamin D3 + Vitamin K2 that we can send home with you at your next visit! We’re happy to review your most recent lab work with you to determine appropriate dosing and insure your body is receiving the nutrients it needs to thrive.
