The Importance of Tracking Vitamin D Changes with Season

As the seasons change it is important to keep in mind our resulting lifestyle changes and how they affect our health. One of the most obvious changes is the amount of sun exposure we receive on a daily basis. Whether it is due to the change in the sun’s angle and the number of hours the sun is up, the increase or decrease in clothing we wear when outside, or the weather that keeps us from going outside, changes in these daily habits will have an effect on our vitamin D levels. For those of us in the Northern Hemisphere, that will most likely mean lower vitamin D and a higher chance of being deficient by the end of winter (NOW).

An analysis of almost 4,000 GrassrootsHealth participants who tested their vitamin D levels and reported that they did not take vitamin D supplements showed that vitamin D levels peaked in the month of August and declined to their lowest levels during the winter months of January through March.

Many of our participants tend to rely more on sun exposure for their source of vitamin D during the late spring and summer months and will therefore decrease supplementation during that time. However, this can be tricky if a few key points are not considered…

• the health benefits of sunshine
• what happens in our bodies when exposed to sunshine
• how and when to make vitamin D from sun exposure and how this is different from taking a supplement

Measuring your levels of specific nutrients, such as vitamin D, omega-3s and magnesium, and other markers of health can offer insights on steps to take to help improve overall physical and mental health.

Research shows that the following nutrients are especially important to overall health:

VITAMIN D

• Vitamin D is needed by virtually every cell in the body, and is essential for hundreds of processes each and every day. It acts as a protector and regulator of all cell types, tissues, and organs, it is able to enhance the functioning of each system of the body to help keep us healthy.
• Approximately 90% of the general US population has a vitamin D level below the scientists’ recommended 40-60 ng/ml (100-150 nmol/L)

OMEGA-3s

• A lower Omega-3 Index is associated with increased risk for heart disease, loss of cognitive function, cellular aging, depression, dry eye disease, and death from all causes
• The recommended Omega-3 Index is 8% or higher – yet 85% of GrassrootsHealth participants were below this level

BALANCED OMEGA-6s & OMEGA-3s

• The AA:EPA ratio and Omega-6:3 ratio are measures of pro/anti-inflammatory fatty acids; knowing these ratios can help you take more specific steps towards achieving lower levels of inflammation through diet and supplements

ESSENTIAL & TOXIC ELEMENTS

• Magnesium deficiency is a contributor to health problems such as musculoskeletal pain, atrial fibrillation, stroke, heart failure, preeclampsia, bone health, mental, emotional & behavioral disorders, diabetes, and even vitamin D deficiency
• Measure additional elements such as Selenium, Zinc, Copper, Zinc:Copper Ratio and toxic elements Cadmium and Mercury

DIRECTLY MEASURE INFLAMMATION LEVELS WITH hsCRP

• Elevated CRP levels have been linked to metabolic syndrome, future heart attacks, stoke, peripheral arterial disease, and the development of diabetes

MEASURE YOUR METABOLIC HEALTH WITH HbA1c

• HbA1c is a measure of how healthy average blood sugar levels have been in the recent few months, and is a better representation of blood sugar health than a single glucose measurement
• Higher levels of HbA1c are associated with higher levels of inflammation, a higher risk of metabolic syndrome, diabetes, and cardiovascular disease

THYROID STIMULATING HORMONE (TSH)

• Measure your TSH levels as an indicator of thyroid health
