Vitamin D And Your Heart Health: Boosting Your Levels

Melanie Thomassian Health Pro
  • Over the last few weeks we've been looking at the importance of vitamin D to our health, and how you can work out if you are deficient.


    If you missed these articles, I urge you to check them out. You can find them here and here.


    Today, I'd like to focus on increasing your vitamin D levels. So, here are 3 natural ways to boost your vitamin D levels...


    1. Sunshine

    Despite much talk about skin cancer these days, the sun is your optimal source of natural vitamin D. Short periods outside each day (season permitting), with as much bare skin as is acceptable, will help to boost your vitamin D levels.

    It is, however, important that you avoid sunburn. Research suggests that as long as you avoid getting burned, regular sun exposure actually decreases the risk of skin cancer (except in those with skin type one). 


    The amount of time you will need to spend in the sun is dependant on so many factors, such as where you live, the time of day, your skin tone, etc. But generally speaking, the time needed to make sufficient vitamin D in your body, is typically shorter and less, than the amount of time it takes for your skin to redden and burn.


    2. Foods

    Food sources of vitamin D are quite limited, but some of these include oily fish, liver, meat, eggs, fortified margarine, and fortified breakfast cereals.


    3. Supplements

    If you live in a northernly climate, it can be difficult, at certain times of the year, to maintain optimal vitamin D levels. This is where supplements can be helpful. 


    The problem with supplements, however, is their potential to cause toxicity. The way to avoid this, is to make sure you have a regular blood test taken, which measures your 25(OH)D. That is the only way to be sure you are not at risk of toxicity.


    I have discussed the test for vitamin D in brief here, and in more detail in this article.


    When purchasing vitamin D supplements, you must make sure you are buying the oil-based preparation, rather than a "dry" pill. 


    You also need to check that you are taking a supplement containing D3, rather than D2. Read the label to find out.


    Vitamin D in Summary

    There are a number of steps you need to follow to optimize your vitamin D levels, and therefore improve your health as a result. These are:

    • During the months from April through to September try to spend some time outdoors at least every other day.
    • If you cannot get sun exposure year round, consider taking an oil-based vitamin D3 supplement — just remember that to avoid toxicity, it is important to have your blood levels tested every 6 months.
    • Your aim is to reach a vitamin D (25(OH)D) blood level of 50–80 ng/ml (125–200 nmol/L).

    Please note: it is always a good idea to discuss any supplements you are thinking of taking with your doctor first, before you begin taking new pills.


    Over the last few weeks, I've been strongly emphasizing the importance of vitamin D, however, it is important to remember that vitamin D should not be relied upon as a sole strategy to prevent or treat heart disease — it is a powerful addition to a broader program of treatment.
