What do the states mean?+
- Solid: well studied, and it works.
- Half-there: the science is still forming.
- A ghost: almost no real studies.
- Hollow: well studied, and it does not work.
- A cord: the pair itself has been tested together.
- Air: nobody has ever tested this pair.

What you’re seeing
- Vitamin B12 renders half-there: for energy and fatigue, the science is still forming.
- Turmeric renders solid: for joints, it is well studied and it works.
- Nothing is drawn between them, because nothing has been run. The empty space is the review.
You can tell before you read a word.
Vitamin D + vitamin K2 is what the other answer looks like. Someone ran the study, so a cord is drawn between them. That is the whole difference.
Fair questions
Is it safe to take vitamin B12 and turmeric together?+
No trial has tested the combination, so there is no evidence either way. Nobody has found a problem, and nobody has looked.
Why does this page say nobody has tested it?+
Because we ran the search and read the results. The date above is the day we ran it. We do not claim a pair is untested without a logged search behind it.
Will this page change?+
Yes, if a trial publishes. We re-run these searches and the page changes from air to a cord the day the evidence does.

The search we ran+
On 26 August 2026 we asked PubMed for trials, reviews and meta-analyses naming both vitamin B12 and turmeric. It returned 2 candidates. We read every one and none gave the two together. This page carries a date because the answer can change: if a trial publishes, the air becomes a cord.

Pairs that have been tested+
- Vitamin B12 has been tested with folate.
- Turmeric has been tested with zinc, probiotics, CoQ10, iron, green tea extract, black pepper.
These are the combinations someone has actually run a study on. Every other pairing here is air.
Worth knowing+
- Vitamin B12: Searching 21 health outcomes returned no trial of vitamin B12 on its own for any of them. This is not the same as a supplement nobody has studied. Vitamin B12 is a nutrient your body needs, and there is research on it. What that research is about is correcting a measured deficiency, and multi-vitamin formulations where B12 is one ingredient among many. None of it tells you whether taking extra helps someone who already gets enough.
