Low back pain is the modern plague. We blame desks, mattresses and workouts, but we rarely look at our micronutrient status. Vitamin D isn't just about bones-it's about muscles, nerves and inflammation. When your D is low, your muscles weaken and pain signals amplify. 🦴☀️
In a systematic review of 29 observational studies, people with low back pain were far more likely to have vitamin D deficiency. The association was strongest in women and in adults under sixty. Severe deficiency doubled the odds of having back pain. Yet vitamin D levels didn't predict how bad the pain felt.
Here's the uncomfortable nuance: correlation isn't causation. Chronic pain can make you sedentary and keep you indoors, lowering your vitamin D. Poor health habits that contribute to pain also reduce sun exposure. The relationship is tangled.
Still, vitamin D matters. It modulates inflammation, maintains muscle strength and supports nerve conduction. Testing and correcting a deficiency is a low-risk move for anyone with stubborn back pain. But don't romanticize it as a cure. Pair it with movement, strength training, good sleep and addressing the structural and inflammatory causes of your pain.
Most people wait for pain to confirm what they already knew. Don't be one of them. See the meta-analysis and take responsibility for the inputs you control.
