Today is the shortest day!
We are heading towards more daylight in the weeks and months to come which is always a positive feeling but we still need to think about supplementing with vitamin D3 due to the reduced sunlight.
This is 1 of only 3 supplements I recommend to clients, everything else can be obtained from your diet.
A pro hormone, vitamin D is created when our skin is given direct exposure to sunlight (midday sun is best as UV rays are strongest).
We can get small amounts from foods like eggs, salmon and some mushrooms as well as fortified foods but it’s unlikely to be enough.
Even in the summer months it can be tricky to get enough in the north east, so taking a higher dose from September to March is beneficial.
You can have your vitamin D levels checked with a blood test but some signs of deficiency are fatigue, joint and bone pain, muscle weakness or cramps and low mood.
Vitamin D is also crucial for calcium absorbtion.
Doses vary. You can go as high as 4000iu but this is the upper level so please do not go higher than this.
Blood tests will help determine dose required but it’s generally safe for adults to use 1000iu daily. Check with your GP /pharmacist especially if using other medication and supplements.
Another interesting fact for you… the darker your skin the less vitamin d you make from sunlight.
