Taking care of you... and your baby

Reduce the risk of premature births

While not all premature babies experience complications, being born too early can mean immediate and long-term health problems, including breathing, heart and cognitive problems, immune suppression, cerebral palsy and ADHD to name a few.

We can help. How?

Research shows that 50% of premature births – over 3,500 – could be prevented simply by ensuring pregnant mothers have enough vitamin D

Reduce the risk of preterm births

There were 15 million preterm births worldwide and more than 1 million infant deaths from preterm birth complications in 2010. New research shows maternal vitamin D levels greater than 40 ng/mL or 100 nmol/L were associated with substantial reduction in preterm birth risk in a large, diverse population of women.

Vitamin D is metabolized by the body from the UV rays of sunshine. We get almost none from food.

The challenge is that we live in Canada. For six to eight months, our bodies get no UV rays at all, in part because we are bundled up from head to toe, and in part because the angle of the sun doesn’t deliver those UV rays. Even in the summer, most people block UV rays with sunscreen – a sensible precaution, but it also prevents vitamin D metabolism.

More: larger people need more vitamin D because it is fat-soluble; older people don’t efficiently make vitamin D from the sun; and people with dark skin screen out the UV rays more effectively. Fortunately, vitamin D is very inexpensive, so taking a few tablets a day is a good idea.

We encourage women to look at the research. Your baby’s health is important.

A series of new double blind, randomized control trials (RCTs) – the gold standard in research – show that vitamin D can have a dramatic impact on pregnant moms.

When pregnant moms reach optimal vitamin D levels (which is a blood level above 100 nmol/L) the result is the decrease in premature births.

Doses required by pregnant mothers vary from case to case, but they are well within the safe levels outlined by Health Canada (4,000 IU per day). In the U.S., hospitals give up to 5,000 IU per day to help pregnant women reach 100 nmol/L.

Dr. Roger Newman, an OBGYN and Vice Chair of Women’s Health Research at the Medical University of South Carolina, is the lead of a Field Trial in South Carolina. So far in his trial, premature births have been reduced by 56%.

Scientists and doctors may call for more studies. And, if we were talking about a prescription drug, waiting could be a sensible option. But this is vitamin D. You get more vitamin D by sitting in the summer sun for 30 minutes than the dose suggested by the RCT.


Research shows that adequate doses of vitamin D reduce not only premature births but positively impact other complications of pregnancy as well. Studies also show that an optimal level of vitamin D in the mother means your baby is born with vitamin D in the blood; and that you can continue passing along vitamin D through breastfeeding.

There are no negative health implications from reaching optimal vitamin D levels.

Please check it out for yourself. We want you to be satisfied. And then please drop by and talk to us. Vitamin D isn’t a miracle drug. In fact, it isn’t a drug at all. It has no side effects or toxicity at these doses. And we measure your blood levels to make sure you are always in the ideal range.

You could avert one of the serious complications of pregnancy. It is worth looking into.

Is vitamin D the new miracle drug?

First of all, vitamin D isn't a drug. It is a vitamin, and one that most people through history have metabolized from sun exposure.
