Vitamin D Deficiency:
The Overlooked Driver of Fibroids in Black Women
What the Science Says.
July is Fibroids Awareness Month, a perfect time to spotlight one modifiable factor that could make a real difference for many Black women. Vitamin D levels.
Black women are two to three times more likely to develop uterine fibroids, often earlier and with more severe symptoms including heavy bleeding, pain, anaemia and debilitating fatigue.
While genetics and hormones play major roles, vitamin D deficiency is an important and overlooked contributor.
The Science Linking Low Vitamin D to Fibroids
Studies consistently show that women with sufficient vitamin D levels have significantly lower odds of fibroids, around 32% lower in some research. Higher levels are associated with slower fibroid growth, reduced incidence and greater chance of regression.
Vitamin D helps regulate cell growth, reduce inflammation and influence the hormonal pathways that fuel fibroids. Supplementation trials have shown it can slow or stop growth and, in some cases, reduce size, especially in deficient women.
Why This Disproportionately Affects Black Women
Darker skin (melanin) reduces vitamin D production from sunlight. This is compounded by lifestyle, diet, obesity and geography. In the UK, limited sunlight (especially in winter) makes deficiency more common among African and Caribbean women.
UK reviews specifically highlight vitamin D as a potential risk factor needing attention.
Many women may not realise they also have B12 deficiency because symptoms often overlap with fibroids and anaemia:
Extreme fatigue
Brain fog
Insomnia
Tingling in hands/feet
Mood changes
Shortness of breath.
On a personal level, hospital consultants advised my GP that I need B12 jabs (3x per week for 2 months, then weekly) due to severe deficiency linked to fibroid-related issues. This has dragged on for two years with only a handful of jabs delivered because of administrative barriers and transport refusals. There is no accountability.
If this is happening despite advocacy, how many women are silently struggling?
Heatwave Risks Are Making Everything Worse
During this current heatwave, many women with fibroids and deficiencies report intensified symptoms:
Crushing fatigue
Insomnia
Dizziness
Lack of motivation to even leave the house.
Heat increases fluid loss, worsens anaemia and puts extra strain on the body, turning manageable symptoms into debilitating ones.
Actionable Steps You Can Take
Get Tested, Request 25(OH)D (Vitamin D), B12, iron and full blood count.
Work with Your Doctor, Discuss supplementation and insist on proper support for any injections or treatments.
Practical Strategies, Safe sun exposure, nutrient-rich foods and hydration (especially in heat). In the UK, consider winter Vitamin D top-ups.
Advocate, Document delays and escalate if care is denied.
Important Caveat:
Vitamin D and B12 support are not cures. They are tools to use alongside proper medical care.
One modifiable factor during Fibroids Awareness Month, addressing deficiencies could reduce suffering, but only if healthcare systems provide consistent, accountable support.
This July, book those blood tests and speak openly with your GP. Share this post with women experiencing unexplained fatigue or heavy periods. If you are facing treatment barriers, document everything and reach out to patient advocacy services.
Follow advocates and do not suffer in silence, tag a friend who needs this. Let us demand better awareness and accountability.
