Pro D3 ®

Vitamin D is one of the essential minerals and vitamins that keep our bodies functioning, but it isn’t always easy to get all we need from the sun during the darkest months of the year. That’s where Pro D3 comes in.

The sunshine vitamin through the post: subscribe to buy Pro D3 online

So why is Pro D3, and other vitamin D products, called the sunshine pill? Well, we get most of our vitamin D from the sun, or at least we should. In Britain, and other areas further away from the equator, this isn’t always easy during the winter months. This is particularly a problem for people with darker skin, which does not process vitamin D from the sun as efficiently as those with lighter skin.

Supplements are the perfect solution, and Pro D3 offers various strengths to provide protection against severe deficiencies that can lead to serious conditions like osteoporosis. Prescription strengths are available, and our UK registered clinicians can provide these after you have filled in a simple online questionnaire.

Subscription packages from EveAdam mean you need never worry about running out of “sunshine” again, with monthly deliveries available. For those that want to buy in bulk, you can also get it delivered every one, two, three, six or nine months.

Sounds great - but what are Pro D3 supplements and treatments?

Pro D3 is a form of vitamin D that the body finds easiest to process. It’s well tolerated and highly effective at preventing severe deficiencies from occurring. It’s available in capsule or liquid form and has a wide range of strengths to suit each need.

Can’t I just buy Pro D3 over the counter?

Yes, you can, but that does mean remembering to buy it when needed. Most people find the maintenance dosages are easier to maintain when you have it delivered, but they’re available to buy over the counter at your local pharmacy.

For some vitamin D products, you will need a prescription. That’s not because clinicians don’t trust you, but because high levels of vitamin D can cause serious health problems, they aren’t always suitable for everyone. These dosages are only prescribed when you have a severe vitamin D deficiency, treating related conditions, such as osteoporosis.

Thankfully, in the case of Pro D3, none need a prescription.

What is Pro D3 used for?

As mentioned above, Pro D3 helps prevent osteoporosis. So what is osteoporosis and what causes it?

Put simply, severely low levels of calcium, partly caused by low levels of vitamin D (alongside low calcium intake, weight, age and some health conditions). This can result in bone deformities and weak or brittle bones. Obviously it’s better to avoid this from occurring in the first place, so be sure to keep your vitamin D levels up when the nights close in over winter.
