10 Signs You Might Be Vitamin D Deficient & What To Do About It

As summer comes to an end, now is a good time to start thinking about getting your vitamin D levels tested. Most of the active vitamin D found in your body, comes from the sun, so vitamin D levels tend to peak now and slowly decline over winter. Getting tested allows you to get a baseline vitamin D level so that you know how much vitamin you need to supplement with.

Vitamin D is a rockstar vitamin (actually, it is really a hormone) and low levels of vitamin D can cause a wide variety of symptoms in your body, which can be easily prevented by ensuring that you are optimizing your vitamin D levels. In this article, you will learn the common symptoms associated with vitamin D deficiency, what can lead to low levels of vitamin D and what to do if you suspect that your levels are low.

10 SIGNS YOU MIGHT HAVE A VITAMIN D DEFICIENCY

1. Depression or anxiety (including mood changes or irritability)
2. Bone softening (low bone density), fractures
3. Feeling tired all the time/ decreased performance
4. Muscle cramps and weakness
5. Joint pain (especially back and knees)
6. Difficulty regulating your blood sugar levels/ post lunch energy crash
7. Low immunity
8. Slow wound healing
9. Low calcium levels in the blood
10. Unexplained weight gain

Symptoms like these are commonly overlooked because they don’t feel life threatening, and they’re often?dismissed as normal, everyday aches and pains, or signs that you are "getting older". But you don’t have to put up with these symptoms of ill health. Understanding why your vitamin D levels are so low and taking steps to correct low vitamin D levels can often improve these symptoms.

WHY ARE MY VITAMIN D LEVELS SO LOW?

• Sun cream. Your body makes vitamin D after contact with the sun’s UV rays but, as we’re a nation of sun cream fanatics (and this covers the skin, blocking the rays of sunlight from getting through), you might not be getting enough straight-up sun.
• Age. Among other things that go a bit wrong as you get older, your body is less good at turning the rays from the sun into vitamin D. Specifically, the kidneys are less good with age at turning it to the active form of calcitriol.?
• Kidney or liver disease of any kind also means vitamin D is not converted to the active form.?
• Tummy troubles. Problems with the digestive system (and I’m not talking about disease here – just an imbalance that may cause anything from a few manageable symptoms to more serious trouble ‘downstairs’) mean the digestive tract does not absorb the vitamin D as well.?
• Obesity (technically that’s a BMI or body mass index of 30+). The fat cells in your body absorb the vitamin D. So then it’s stored – unusable – in your fat cells.?
• Lack of sleep.? Just as you need sunlight to?make?vitamin D, you need sleep to actually?use?it.
• Stress. The presence of the stress hormone cortisol reduces the uptake of vitamin D by special vitamin D receptors. It literally sits there, in the body, without being able to be used. What a waste!
• Your complexion. The darker your skin tone, the less vitamin D you will make. This is due to the higher levels of melanin in your skin, which protects against UV light. But blocking the sun’s rays, also curbs the body’s ability to make the pre-cursor to active vitamin D.?
• Nightshift workers and anyone else who doesn’t spend much time in the sunlight, including children wearing sun cream all the time and babies. Quite simply, you need the sun on your skin.?

HOW DO I GET TESTED

If any of the above resonates with you, then you should definitely get tested. You might find your GP will do this for you. My experience is that they are usually amenable to this particular test.?

If your doctor won’t test, consider getting it checked out privately. In the big scheme of things (you know, like quality of life and your health), the test is not expensive but it could change your enjoyment of your life.?

The test is the 25-hydroxy vitamin D test (also known as the 25-OH vitamin D test or Calcidiol 25-hydroxycholecalciferol test). It’s the most accurate way to measure how much vitamin D is in your body.

Your doctor will want to know that there is a valid reason for having you tested. Go back through the list of symptoms and go in strong with this being the reason why you want to be tested.?

If you’re the kind of person who doesn’t want to ask, feels uncomfortable asking or is just curious to know their levels, you can get the test done privately for around ￡44. It’s a finger prick test, so you can do it easily at home, then get guidance on how much to supplement safely. If this is you, and you want to know more, send me a message and we’ll talk.?

If you do take a test and you’re very low, you’ll need an intense 4-6 weeks supplementation at a high dose and then re-testing to see the impact it’s had.? There is such a thing as too much vitamin D (known as vitamin D toxicity). You’d have to be going some way to get there, but it is possible, which is why it is essential you know your levels before you start guzzling any supplements.?

I know what you’re thinking. Here’s a few of those ‘yes, buts’ you have going on…

• I already take a vitamin D supplement.??
• I go out in the sun quite a bit
• Wouldn’t my doctor ask to test me if they thought it were a problem?
• I’m too busy to take time off to take a test.?

I hear you.

You might be thinking that you don’t have any major symptoms, or that you love the sun and spend as much time as possible out doors, and feel that the test would be a waste of time.

But the thing is…

Some of my clients, myself included, have been very surprised to find that their vitamin D levels come back, as low as 1/4 of what they should be, despite regular sun exposure.

So the moral of this story is, get tested.

HOW TO UP YOUR VITAMIN D

• Get yourself some sun. Recommended sunlight exposure is between 10 and 30 minutes a day with no sun cream.?
• If getting out in the sun is not an option, sit in front of a light box?that supplies 10,000 lux of full-spectrum light for 30 minutes every morning. This is an especially good option for winter months, for night shift workers.?
• Take a supplement.?You can take a generic 1,000 IU dose as an adult (but not children without consulting your GP) BUT, if you’ve no idea what your blood levels are, how to you know how much you should be taking?
• Eat naturally vitamin D-rich foods like oily fish (salmon, sardines, fresh tuna, trout, halibut, mackerel, et.), high quality cod liver oil, egg yolks and liver. Do not be fooled into thinking the fortified foods are the same or have similar benefits. Fortified foods (like cereals, margarine and some yoghurts) contain a synthetic version of the vitamin known as D2 (the natural form is D3). Research shows this is less effective at raising levels of vitamin D in the blood.
