Buy Strivit D3 online: the sun, captured in a soft gel capsule

The sun. It provides life to the planet, but sometimes it’s hard to remember it exists when you’re in the middle of winter in countries like the UK. It does come with some advantages though; there’s nothing like a cosy night in when the temperature drops!

It can be hard on your vitamin D levels though. Even when the sun does shine, it’s unlikely to provide much help as it isn’t strong enough to provide the body with vitamin D.

And that’s where supplements and treatments like Strivit D3 come in. Taking one supplement capsule a day can keep your levels healthy, and stronger doses can help prevent serious conditions when deficiencies are severe.

Why is it called the sunshine pill?

We should get most of our vitamin D from the sun, for free! If you live in a country close to the equator, you will likely not require vitamin D supplements as the sun is strong enough all year round to provide what you need. The next best thing is to manufacture vitamin D in a capsule, such as Strivit D3, which is why it can be referred to as a sunshine pill.

What are the benefits of taking Strivit D3?

Health! But more specifically, it can help to keep your bones, muscles and teeth in good shape, as well as lift your mood and energy if you have a vitamin D deficiency. Vitamin D deficiency has been described as an ignored epidemic, so many people in the UK are struggling without knowing the reason why.[1] Strivit D3 is one of a number of products that can greatly improve your levels and your general health as a result.
