Is It Better To Take Vitamin D Every Day Or Weekly?

If there was a prize for the best multitasking vitamin - Vitamin D would win hands down. After all, it acts as both a hormone and a vitamin which is pretty impressive. But how much should you really be taking? And is it best to take it every day or just once a week? Read on to find out.

Key Takeaways

  • Vitamin D is a fat soluble vitamin found in oily fish and egg yolks.
  • Most people don’t get enough of this essential vitamin, especially during the winter months.
  • Supplementing a daily dose of Vitamin D may be safer and more effective than a weekly mega dose.

What Is Vitamin D And Why Is It Important?

Not only does Vitamin D promote the absorption of calcium, magnesium and phosphorus via the intestine, but it also supports your immune health, reduces inflammation and helps you with weight loss. (Source)(Source)

Many of us don’t get enough Vitamin D, which can affect the health of our bones and teeth.

It can also put us at higher risk of chronic diseases such as MS, raise our risk of depression, and make it more likely we’ll get worse bouts of flu and COVID-19 in the winter. (Source)(Source)

Your body has multiple Vitamin D receptors all over the body – which illustrates just how important a role it plays in your health.

Sources Of Vitamin D

Where Can You Get It From?

The best source of Vitamin D is from the sun itself. After all, it’s not called the sunshine vitamin for no reason.

This means we need to be getting between 10-30 minutes of unprotected sun exposure daily if we can.

This timing varies based on the color of your skin. If you are very fair-skinned then more than ten minutes of direct sunshine could lead to burning which damages the DNA and can lead to cancer.

But for people with darker skin, more time is needed for sufficient absorption.

And either way, midday is your best chance at getting good sun exposure as it’s when the sun shines more intensely then.

Aside from the sun, you can also obtain Vitamin D from different types of food too. For example, Vitamin D3 is present in animal-based products such as oily fish and egg yolks.

But if you follow a plant-based diet fear not – you can also get Vitamin D2 from foods such as UV-treated mushrooms and fortified orange juice/cereal.

Vitamin D Dupplementation

In an ideal world, we’d get all the Vitamin D we need from sunshine and diet alone.

But unfortunately, it’s not an ideal world. And in northern Europe (including the UK) we simply don’t get enough sunshine during the winter months.

This is why Vitamin D is the only vitamin that the UK government recommends we supplement from October – March. (Source)

Because the evidence suggests, this could make a big impact on our health.

It’s definitely still worth aiming to get a daily lunchtime stroll, and eating plenty of oily fish and fortified foods because these have their own health benefits anyway.

But when it comes to Vitamin D, it’s really not something you want to become deficient in. So some preventative supplementation is well worth it.

Is It Better To Take Vitamin D Every Day Or Weekly?

The ideal daily amount is around 600-800 iu per day – which equates to about 15-3 mcg. 

Some studies have looked at whether taking one individual supplement dose of around 1.25 mg once a week could work just as well as a daily amount.

But evidence shows that a weekly dosage doesn’t seem to help unless you take quite a lot. And there are risks attached to this.

This is because Vitamin D is fat-soluble, so it can potentially store excess amounts in the body. It’s not like water-soluble Vitamin C which gets excreted via your urine if you take too much.

And Vitamin D toxicity is not something you want to get as it can cause issues such as hypercalcemia, which has a range of unpleasant symptoms.

Luckily you would need to take an awful lot to create those effects – but still, most experts state it’s best to take a daily maintenance dose of Vitamin D instead of a weekly mega dose.

So if you’re wondering about Vitamin D, once a week vs daily – little and often appears to be the way forward.

And normally, remembering to take different supplements daily can be a nuisance. It’s hard to remember, and you can end up just wasting your money.

Which is why, as a nutritionist, I would recommend you make life easy for yourself. Because with all good things – consistency is key.

At least if you want to see results, that is.

So, why not choose a multipurpose supplement such as Supergreen Tonik and address multiple health concerns simultaneously?

Here you can get a daily dose of Vitamin D, plus much much more.

And if you are trying to eschew animal products, then fear not because Supergreen Tonik has kindly provided you with Vitamin D in its plant-based D2 variety too.

Many people might choose to just take a multivitamin with Vitamin D in it, but there is actually a wide range of advantages to taking a greens powder with vitamins instead.

For a start, you’ll get more antioxidants and unique green-based benefits from additions such as chlorella and spirulina.

And if you choose wisely, you might get some added extras too.

For example, Supergreen Tonik offers an adaptogenic bonus blend rich in mind-calming, focus enhancing and cognition-boosting aids such as ashwagandha and l-theanine.

On top of this, you can also find their immune-boosting blend with garlic and olive leaf extract, which pairs nicely with Vitamin D to offer you much-needed immune support during the winter and beyond…
