Vitamin D and K provide a strong authorised benefit platform. Vitamin D contributes to normal immune function, normal muscle function, normal blood calcium levels and maintenance of normal bones and teeth. Vitamin K contributes to maintenance of normal bones and normal blood clotting.
The Formulae5 D3 + K2 formula
Vitamin D3 & K2 provides vitamin D3 4,000 IU (100 micrograms) and vitamin K2 MK-7 100 micrograms, with added magnesium, calcium and zinc. Vitamin D is not presented as reducing tiredness or raising energy levels.
Where turmeric fits
Turmeric combines turmeric 1,200 mg with ginger 200 mg, black pepper and vitamin D3 4,000 IU. Curcumin-containing preparations have shown promising joint-related results in human research, but outcomes vary significantly by formulation and should not be translated into disease-treatment claims.
Safety
Each product supplies 100 micrograms of vitamin D3, the adult tolerable upper intake level cited in UK guidance. Do not stack them or combine with other vitamin D supplements unless a qualified healthcare professional advises you to. Vitamin K and turmeric can also interact with some medicines.
