Vitamin D is fat-soluble, so you must intake it with a source of fat. 

Take 1 capsule per day with a meal. 

After 2 to 3 months of taking vitamin D with a main meal, blood levels of vitamin D have been proven to increase by 50%. It is also a good idea to take vitamin D in the first half of the day, as it can affect melatonin production and consequently affect the quality of sleep.

Caution!

The high dose of 4000 IU is not intended for prolonged use. Take when dealing with vitamin D deficiency or under the supervision of your physician.

Obzirom da sam tek počela nemam baš neki pametan komentar.....

Pozdrav Branka,

hvala ti što si podijelila prvi dojam. Kako si tek počela koristiti proizvod, možda je još malo prerano za konačnu ocjenu. Nadamo se da ćeš nam se javiti ponovno nakon duljeg korištenja i, ako se tvoj dojam promijeni, ažurirati i svoju ocjenu.

Ho iniziato a prendere la vitamina D su consiglio

Ho iniziato a prendere la vitamina D su consiglio dell' ortopedico in quanto ho problemi di artrosi ad un ginocchio. Devo dire che da quando lo prendo le condizioni si sono stabilizzate e riesco ad andare in bici senza problemi di dolore.

Ciao!

Grazie mille per aver condiviso la tua esperienza! Siamo davvero felici di sapere che la nostra vitamina D ti sta aiutando e che riesci a pedalare senza problemi di dolore. Ti auguriamo di continuare a ottenere ottimi risultati e ti ringraziamo per la fiducia che hai riposto in noi.
