Product description

Physiological functions, notes on high or insufficient intake and relevant interactions — presented separately from the specific product assessment.
Vitamin D3
Vitamin D is a fat-soluble vitamin and also a precursor of hormonally active metabolites. For the assessment of supplements, product dose, dosing interval, total intake, 25-OH-vitamin-D status and safety limits are considered separately.
Functions
EU-authorised functions include, among other things: vitamin D contributes to normal absorption and utilisation of calcium and phosphorus, normal blood calcium levels, the maintenance of normal bones and teeth, normal muscle function and normal functioning of the immune system. Vitamin D also has a role in the process of cell division.
Possible signs of insufficient intake
Inadequate vitamin D status cannot be reliably identified from individual nonspecific symptoms. For individual assessment, 25-OH-vitamin-D status together with exposure, diet and supplemental intake is more informative than symptoms alone.
Points to consider at high intake
A markedly excessive vitamin D intake over a prolonged period can lead to hypercalcaemia and hypercalciuria and thereby place a burden on the kidneys and other organ systems. Upper Intake Levels are safety limits for long-term intake and are not optimal target values.
Special considerations
Particular caution is required, among other situations, with diseases or therapies that affect calcium metabolism or kidney function. High doses should not be derived solely from general target values.
Interactions / caution
Vitamin D can interact with certain medicines; relevant examples include drugs that affect calcium or vitamin D metabolism. With prolonged higher-dose use, individual medication should be taken into account.
Vitamin K2
Vitamin K2 belongs to the vitamin K family and includes various menaquinones such as MK-4 and MK-7. MK-7 is commonly used in food supplements. K1 and K2 should not be treated as generally equivalent, even though the authorised vitamin K functions apply to vitamin K as a whole.
Functions
EU-authorised functions: Vitamin K contributes to normal blood clotting and to the maintenance of normal bones.
Possible signs of insufficient intake
Insufficient vitamin K status can impair vitamin-K-dependent blood clotting. An individual assessment should not be based solely on nonspecific symptoms.
Points to consider at high intake
No numerical US UL has been established for vitamin K because of insufficient data and the comparatively low observed toxicity. This does not mean that unlimited dosing is safe, particularly in the presence of relevant medication.
Special considerations
Particular attention is required in people taking vitamin-K-antagonist anticoagulants. In this context, independently changing vitamin K intake is not advisable.
Interactions / caution
Vitamin K can interact clinically significantly with vitamin K antagonists such as warfarin, phenprocoumon and similar anticoagulants. During such therapy, vitamin K intake should only be changed in consultation with the treating medical team.
Scientific assessment
Studies, meta-analyses and randomized controlled trials on the active ingredient – explained clearly and linked to sources.
