Vitamin Status in Patients with Phenylketonuria: A Systematic Review and Meta-Analysis

24 studies compared 770 people with early-treated PKU and 2387 healthy controls.
Both points are doses of a standardised saffron extract (affron) in adults with low mood. A 4-week RCT in 128 adults (PMID 28735826) gave 22 or 28 mg a day: mood improved at 28 mg (POMS total mood disturbance versus placebo, d = -1.10) with no effect at 22 mg. A 12-week RCT in 202 adults with subclinical depressive symptoms (PMID 40414301) confirmed a smaller benefit at 28 mg (DASS-21 depression, d = 0.39). Doses above 28 mg were not compared with lower ones in these trials, so no optimal dose or safety ceiling is plotted. The cited depression meta-analyses pool trials without comparing doses.

Vitamin B12 has a higher evidence score (7.5/10 vs 7.5/10) and wins in 1 of 3 categories.
For support mood, Saffron has a higher relevance score (90 vs 55).
No documented interaction was found in the data searched. This does not establish that this exact combination is safe.
Saffron, EPA omega-3, SAMe have real adjunct evidence — but these aren’t a substitute for care, and some interact dangerously.
