Who Needs Vitamin D3 1000iu?

UK Government advice is that everyone should consider taking 10mcg (400iu) of vitamin D daily for healthy bones and muscles. This is particularly important during the winter months.

NHS Inform states that certain groups are at increased risk of vitamin D deficiency and should take a daily 10mcg (400iu) vitamin D supplement all year. These groups include:

  • All pregnant and breastfeeding women.
  • Infants and children under 5 years old (unless consuming over 500ml of infant formula daily).
  • Individuals with low or no sun exposure, such as:
    • Those who cover their skin for cultural reasons.
    • People who are housebound or stay indoors for long periods.
    • Residents of care homes.
  • People from minority ethnic groups with dark skin (e.g., African, African-Caribbean, South Asian origin), as they require more sun exposure to produce the same amount of vitamin D.

To understand the health implications of low vitamin D3 levels, read our comprehensive Vitamin D Guide.

Our product range includes a full spectrum of vitamin D supplements, from low-dose vitamin D to high-strength vitamin D. We also feature synergistic vitamin D and K supplements. Review our comprehensive vitamin D offerings.

Did you know?

Once a patch of skin produces vitamin D that area stops producing for the rest of the day? For those who do not tend to have their skin exposed to the sun frequently in the summer months, vitamin D supplements can be a fantastic addition to help make up for this limited vitamin D production.
