Description

Double Strength Vitamin D3 offers a powerful dose of this essential vitamin in every tablet, providing 5000 IU.

Vitamin D, often referred to as the sunshine vitamin, is crucial for maintaining overall health. Your body naturally produces Vitamin D when your skin is exposed to sunlight. However, many factors can limit your sun exposure, making it challenging to produce enough Vitamin D, especially during the winter months or if you spend most of your time indoors.

Vitamin D plays a vital role in supporting the normal function of the immune system, and is also essential for the maintenance of normal bones and muscle function. Additionally, Vitamin D helps regulate the levels of calcium and phosphate in your body, which are crucial for healthy bones and teeth.

Given the difficulty in obtaining sufficient Vitamin D from sunlight alone, especially from October to March, the NHS recommends that everyone in the UK take a Vitamin D supplement during these months. Double Strength Vitamin D3 ensures you receive an adequate daily dose to keep your levels topped up and your body functioning optimally.

Choose Double Strength Vitamin D3 to maintain your health and wellbeing all year round. Suitable for vegetarians, this supplement provides a convenient way to ensure you meet your daily Vitamin D needs.

Key Features:

  • 2x more vitamin D3 than most similar supplements (5000iu compared to 2500iu.
  • Supports the normal function of the immune system
  • Contributes towards the maintenance of muscle and bone function
  • Rigorous testing and transparency ensures you know exactly what you are putting in your body.
  • Outstanding value: 180 tablets per bottle, providing up to 6 months supply.

Need to take a break from your subscription?

You can simply sign in to your account on our website, or click the link in any email sent you about your subscription, to view, change or cancel your subscription.

Subscriptions can be cancelled with a single click after your first refill.

PLEASE NOTE: cancelling your subscription is not available until after your first refill - meaning your 2nd shipment. 

This is done to ensure we can continue to offer discounts to all those who wish to subscribe. 

When a customer subscribes, we do not have to pay substantial marketing costs to Google or Facebook for each order. This allows us to pass these savings on to you. 

But, this falls apart if people place a subscription order to receive the free shipping and discount on their first order with us, and then immediately cancel their subscription. 

Therefore, to be able to continue offering significant cost savings to subscribe and save customers, we have sadly had to make it only possible to cancel a subscription any time after the customer has received their first refill (meaning the second shipment of the product they subscribed to).

Trusted VD

I have been taking Double Strength Vitamin D3 5000iu Tablets - 180 per bottle since 2020 following COVID, I take 10000iu daily and I have had no coughs, sore throats or chest infections. As a diabetic for over 36 years I have 2 full blood tests a year and the blood tests always come back with the normal level of Vitamin D3 needed to remain healthy in the UK during the winter climate. I buy in bulk as my immediate family are also taking Vitamin D3. IT WORKS!

Section Image

A Double Dose

Each tablet provides a double dose compared to regular Vitamin D3 supplements.

Absorbs Like a Sponge

Made with a granulated binding formula to ensure more of the essential nutrients are digested and absorbed.

Exceptional Value For Money

With a high strength dose in each tablet, every bottle of 180 tablets lasts up to 6 months.

Maximum Potency

Packing 5000iu of Vitamin D3 into every tablet ensures you get the dose you need when you're otherwise lacking.

Proudly made in the USA and the UK to the strictest of standards

A double dose of Vitamin D3

We began in 2005 with a mission to create health supplements that are potent and truly effective, making a noticeable difference in the lives of those who use them. Our Double Strength Vitamin D3 continues this proud tradition.

Each Double Strength Vitamin D3 tablet contains 5000 IU of Vitamin D3, providing twice the dose of regular vitamin D3 supplements, which usually offer only 2000-2500 IU per tablet.

This ensures that you receive the necessary dosage with just one tablet, making it a convenient and cost-effective choice.

As advertised
Finding other Vitamin D3 supplements that claim to provide 5000 IU is not so difficult, but finding on with that amount in a single tablet is much more challenging.

A quick glance at the back of the label often reveals that the stated strength is per serving, not per tablet, with the serving size necessitating up to 3 tablets or capsules to achieve the claimed dose.

Our Double Strength Vitamin D3 delivers the full 5000 IU in just one tablet, making it a more convenient and economical choice.

A better vitamin D3

We developed Double Strength Vitamin D3 with both strength and purity in mind.

In producing our Vitamin D3, we partnered with our manufacturers to implement a purification system using advanced and sustainable techniques that results in an very high quality Vitamin D3.

High purity and sustainable
A key method in our process is Supercritical Fluid Extraction (SFE), which utilizes recycled carbon dioxide (CO2) as a solvent. This environmentally friendly technique operates under high pressure and moderate temperature, allowing CO2 to act as both a gas and a liquid. In this state, CO2 effectively dissolves impurities and isolates the pure Vitamin D3. Once the extraction is complete, the CO2 is easily removed and recycled, resulting in minimal environmental impact and a highly pure product.

Get more from your vitamin D3
Because the SFE process operates at relatively low temperatures, the integrity and potency of our Vitamin D3 in preserved, meaning it remains stable and active for far longer, and is more readily absorbed by your body.

Value for money
Our mission is to make wellness accessible to everyone. That's why we offer Double Strength Vitamin D3 at an affordable price.

With 180 tablets per bottle, each bottle provides a six-month supply, delivering exceptional value.

Key ingredients

Vitamin D3 5000iu +

Vitamin D3, also known as cholecalciferol, is a fat-soluble vitamin that is crucial for the maintenance of overall health. It is one of the two major forms of vitamin D, the other being vitamin D2 (ergocalciferol).

Diet alone may not always provide sufficient amounts of Vitamin D3, as it is naturally present in only a few foods. While fortified foods can help, supplements ensure you meet your daily needs more consistently and conveniently.

Supplementing with Vitamin D3 is particularly important if you have limited exposure to sunlight, live in a region with long winters, or spend a lot of time indoors.
