Vitamin D3 Gummies

Vitamin D3 is one of the fourteen vitamins and minerals in the Daily Greens+ gummy, part of the daily GUUDIES pouch. It is present at 20µg per serving, which is 200% of the nutrient reference value.

D3 rather than D2

Vitamin D comes in two forms. D2 is ergocalciferol, found in some fungi. D3 is cholecalciferol, the form your skin produces when exposed to sunlight and the form found in animal sources. We use D3.

Amounts are often written in either micrograms or international units. 20µg is the same as 800 IU, which is why you will see both figures used across the category.

Why the UK is a special case

Britain sits far enough north that between October and early March the sun does not get high enough in the sky for UVB to reach the ground in useful amounts. Skin cannot make vitamin D from sunlight during that window, whatever the weather does.

Because of that, the NHS advises that everyone in the UK consider taking a daily vitamin D supplement through autumn and winter, and that some groups consider it year round. It is unusual for official guidance to be that direct about a supplement, which is why vitamin D gets more attention than most.

Fat soluble, so take it with food

Vitamin D is fat soluble, along with A, E and K. That means it is absorbed better alongside dietary fat than on an empty stomach, which is why we suggest taking the whole pouch with or after a meal.

It also means it is stored in the body rather than passed out in urine, so there is an upper limit worth respecting. Stick to the stated dose and do not stack multiple vitamin D supplements without speaking to your GP.

Where else you find it

Oily fish, egg yolks, red meat and liver are the main dietary sources. Some foods are fortified, including many breakfast cereals and most plant milks. Very few foods contain it naturally in large amounts, which is the underlying reason supplementation comes up at all.

Which gummy carries it

Vitamin D3 sits in Daily Greens+, tropical flavour, alongside vitamins A, C, E, the B complex, vitamin K2, zinc, copper, iodine and chromium and the superfood greens blend.

Common questions

How much vitamin D is in GUUDIES?

20µg per daily serving, which is 200% of the nutrient reference value, or 800 IU.

Is it D3 or D2?

D3, cholecalciferol. That is the form your skin makes from sunlight.

Is the vitamin D3 vegan?

The Daily Greens+ gummy is vegan. Five of the six GUUDIES gummies are vegan; only Marine Collagen is not, since it contains collagen from fish.

Do I need vitamin D in summer?

The NHS advises considering a supplement between October and early March for everyone, and year round for some groups. Your own circumstances are worth discussing with your GP.

What is 20µg in IU?

800 IU. Both units are used across the supplement category, which is a common source of confusion.

Should I take it with food?

Yes. Vitamin D is fat soluble, so it is absorbed better alongside a meal.
