Why Take Vitamin D?

Dr Marks Vitamin D3 4000IU pairs a high-strength dose of D3 with Vitamin K2 — vitamin D and vitamin K both contribute to the maintenance of normal bones.

Why add K2?

Vitamin D contributes to the normal absorption and utilisation of calcium, and vitamin K contributes to the maintenance of normal bones. We include 100µg of vitamin K2 as menaquinone-7 (MK-7) in every capsule.

Why Dr Marks?

Ours is dosed at a high-strength 100µg (4000IU) of vitamin D3, at the top end of what UK guidance considers safe for daily adult use, paired with 100µg of vitamin K2 (MK-7). It's formulated by GPs to the dose they'd actually recommend.

Directions

Take one capsule daily with food. Suitable for adults. Consult your GP if pregnant, breastfeeding, on anticoagulant medication, or taking other medication.

Vitamin D needs little introduction — it's one of the most commonly recommended supplements, especially over autumn and winter.

Our capsules provide 100µg (4000IU) of Vitamin D3 (cholecalciferol) per daily dose, together with 100µg of Vitamin K2 as MK-7 (menaquinone-7).

Directions: Take one capsule daily, with food for best absorption (Vitamin D is fat-soluble).

Format: Vegetable capsule (HPMC) — suitable for vegetarians.

Storage: Store below 25°C in a cool, dry place, out of direct sunlight. Keep out of reach of children.

Please speak to your GP before use if you are on anticoagulant medication, have a condition affecting calcium levels such as hyperparathyroidism or sarcoidosis, or are pregnant or breastfeeding.

Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. Do not exceed the stated dose.
