Frequently asked questions about Vitamin D3
Can I safely take 4,000 IU per day?
4000 UI es el nivel máximo tolerable establecido por la EFSA para adultos. Es una dosis adecuada para corregir déficits y para el mantenimiento en períodos de poca exposición solar.
When is the best time to take vitamin D3?
With the main meal of the day, as being fat-soluble it is better absorbed in the presence of fats.
How long does it take for vitamin D levels to rise?
With regular supplementation, levels usually normalise within 8-12 weeks. A follow-up blood test is recommended if there is a confirmed deficit.
Is it necessary to combine it with vitamin K2?
La K2 ayuda a dirigir el calcio hacia los huesos y evitar su depósito en las arterias. Si tomas dosis altas de D3 a largo plazo, combinarla con K2 MK-7 puede ser beneficioso. Consulta con tu médico.
