Key takeaways
- Vitamin D supports bones and muscles.
- It helps manage inner-ear calcium.
- Low levels are common after 50.
- 600–800 IU daily is recommended.
- A blood test shows your level.
Vitamin D is best known for bones, but it also plays a role in how steady you feel on your feet.
Three ways vitamin D supports balance
Strong bones
Vitamin D helps absorb calcium, keeping bones strong.
Muscle function
Muscle cells have vitamin D receptors, and low levels are linked with weaker muscles and slower reactions.
The inner ear
The inner ear's otoconia are calcium-carbonate crystals; vitamin D helps regulate calcium metabolism, and researchers have studied vitamin D in people with positional vertigo.
How much vitamin D?
| Age | Recommended daily | Upper limit |
|---|---|---|
| 19–70 | 600 IU (15 mcg) | 4,000 IU |
| Over 70 | 800 IU (20 mcg) | 4,000 IU |
Getting enough
Sources include sensible sun exposure, oily fish, egg yolks and fortified foods. Many older adults benefit from supplementation, ideally guided by a blood test. VertiAid combines vitamin D3 with Aquamin® minerals, collagen and active vitamin B6 in a daily chewable designed for balance support.
