Vitamin D supplementation is officially recommended by the NHS for everyone during autumn and winter. However, you should also considering taking a supplement all year round if you staying indoors for extended periods of time, have dark skin, are pregnant or breastfeeding, or suffer from low mood or seasonal affective disorder (SAD).

Vitamin D is a nutrient that your body makes when you’re exposed to the sun. Most people find it impossible to get enough from diet alone as only 10% of your Vitamin D intake can be obtained from foods like meat, oily fish, dairy & eggs.

90% of our vitamin D is obtained from consistent access to sunlight. So if you aren't getting consistently getting enough, a supplement can help.

Yes. This product has been formulated to work well with our other products that don't contain a large amount of vitamin D. Lots of customers choose to pair this with Puro Multivitamin to support optimal daily well-being as it has a lower dose of vitamin D.

The Vitamin D3 in this formula is sourced from lanolin and so only suitable for vegetarians but not vegans. However this product contains vitamin K2.

The D3 in our Puro Vitamin D3 formula is sourced from lichen algae which is a plant-based source making the product suitable for vegans. However it does not contain any vitamin K2.

When you significantly increase your vitamin D intake, it can cause a rapid increase in calcium levels.

Vitamin K helps your body absorb this calcium to ensure it goes to the right places (i.e. your bones and muscles) and isn't deposited into undesirable places like arteries or soft tissue which can cause serious health complications.

Puro Vitamin D3 + K2 is our high-strength clean formula made in the UK with no hidden additives or any nasty fillers.
