Heavy forehead schvitzing that doesn’t seem to match the situation you’re in (think, simply sitting at your work desk) is a big indication your levels aren’t up to scratch.

3. You hurt all-over
It’s often subtle, but many sufferers experience chronic inflammation and aching in their joints – a condition that’s also known as osteomalacia.
4. You’re feeling down-in-the-dumps
Symptoms of depression and vitamin D deficiency often go hand in hand - this is coz the mineral works in the same areas of the brain and impacts the same hormones (like serotonin) as those that affect our mood.
5. Your immune system is shot
Low levels of vitamin D can lead to a sluggish immune system, which means no matter what it is – cold, viruses, flu - you’ll catch it if it’s going around.
