Why you need Vitamin D
Did you know Vitamin D works like a hormone in the body?
Four of the most important functions that need Vitamin D:
- Hormone balance
- Immune function
- Brain health
- Mood regulation
If you feel sluggish, low in motivation and low immunity, you could be deficient.
The body needs Vitamin D to create natural serotonin, so if you suffer from SAD, or seasonal affective disorder, you are almost certainly deficient in Vitamin D.
Vitamin D also supports healthy ageing and reduces the risk of diabetes and cardiovascular disease.
Causes of Vitamin D deficiency
1. Insufficient sun exposure
We need full sunlight on bare skin for at least twenty minutes to absorb Vitamin D naturally.
Hats, sunscreen and sunglasses mean we rarely get enough sunshine exposure in the summer months to build up a good store.
Even if we do, it doesn’t last through winter.
This is why in the UK we are all at risk of deficiency, especially between October and March.
2. Insufficient Vitamin D in the diet
Modest levels are available in:
- Oily fish
- Egg yolks
It’s impossible to take in enough Vitamin D through a normal diet.
This is why I recommend Vitamin D supplements to everyone.
What to look for in a supplement
- Vitamin D3 rather than D2
- Combined with K2 as this increases its efficacy
- *400iu daily or 10mg is the minimum dose
- Spray, capsule or powder can all be effective
- If you have symptoms consider having your levels tested
*Public Health England recommends this as the daily dose, though this won’t correct a severe deficiency.
Homeopathy can support the underlying causes of low immunity and winter depression through a holistic approach. [Related post]
But I always recommend Vitamin D supplements alongside.
