What it is
- B vitamins are water-soluble vitamins involved in energy metabolism and nerve function.[NIH Office of Dietary Supplements][NIH Office of Dietary Supplements]
- A 2019 meta-analysis linked B-vitamin supplements with lower stress ratings, with less clear effects on depressive symptoms and none found for anxiety.[PubMed]
Safety and interactions
- Taking more than 100 mg a day of vitamin B6 for long periods can cause nerve damage (the NIH upper limit is 100 mg a day for adults).[NIH Office of Dietary Supplements]
Supplements can interact with medicines. Talk to a doctor or pharmacist first, especially if you are pregnant, take prescription medicine, or have red-flag symptoms. See supplement safety and interactions.

4/5 Falling asleep“Do that first for a week before taking more than the DRI of P5P.”
4/5 Cost“That high dose may be good for someone with a genetic mutation that they can't absorb or utilize B12 normally.”
3/5 Stomach upsetMood“B vitamins only do something noticeable if you were actually low or you convert them poorly.”
4/5“I had crippling anxiety and I felt my best when I took Citicoline+ 16hr intermittent fasting everyday + creatine 10g + Omega 3/Fish oil 1000 + Circumasorb + Vitamin B12 + Vitamin D”
4/5 MoodSide effects“It was useful for actionable things too like MTHFR (need methylfolate/methyl B12), vitamin d receptor mutation (need higher doses), slow MAO-A (why MAO inhibitors were a dud for depression) and minor PKU definitely helped me optimize my…”
4/5 Cost“Yeah the P5p is supposed to help mag absorption or get into your cells from memory.”
1/5“Methylated B vitamins, gave me the worst panic attacks in my life”
2/5 Side effects“i tried both methylated and non-methylated b vitamins, as well as plethora of other multivitamins”
4/5“What helped me most was staying in the present, meditation/breathing work, avoiding caffeine completely, reading books, eating a clean diet and working on my microbiome, taking Vitamin D, iron with Vitamin C, B12, and magnesium glycinate…”
2/5 Stomach upsetSide effects“Blood work came back and I was very low on multiple vitamins, D, B12, omega, copper, and others.”
2/5 GrogginessSide effects“Co-factors include TMG (Glycine Betaine), B-vitamin complex, Methylcobalamin by itself, Mg and Zn.”
4/5 Mood“But when i take a multivitamin or b complex it helps with energy + mood.”
4/5 Calming effect“Yes im taking b6 , zinc , magnesium for about a week and i feel calmer and my sleep improved !”
2/5 Fast-acting“Slow COMT here and I've been working on my methylation for the last 6 months, have come a long way thankfully, and I still can't take methyl b12.”
4/5 Side effects“Low b12 I think caused heart palpitations and anxiety for me.”
4/5 Mood“I have been taking P5P form of B6 and can confirm I also tested on the low end of normal for glutamic acid which I think is like testing low for glutamate.”
4/5“B12 gave me weird energy at first then reduced anxiety once my levels normalized, but if you're taking the methyl- version it can increase anxiety for some through a different mechanism.”
2/5“Check your vitamin D3, B12 and iron, and increase those levels to above the border line.”
4/5“The only b complex that works for me is Jamieson Stressease.”
4/5“I figure out I was severely undermethylating and TMG, b vitamins and creatine have really helped me.”
1/5“I've been D3 and b12 deficient and both times I had terrible anxiety as my main symptom.”
2/5“My b12 was low (200 something) so I've been taking b12 supplements for a couple weeks, I don't think this is the root of my fatigue issue.”
4/5 Stomach upset“I'm low on b12 and vit d and can't digest magnesium but do take epson salt to help with magnesium.”
3/5“The same with B12 and methyl-B vitamins.”
4/5“Since I last posted I had my bloods checked and my B12 is very low - on researching there is a lot of corrilation to low b12 and bladder urgency as its affecting the nerves around the bladder and making them spasm - I've just started…”
4/5“I'm trying to take iron and b12 to get my levels up, as I hear this helps with hormonal stuff.”
4/5“I only found B complex helps me sleep, which then makes anxiety better.”
2/5“Also, by the way we are both b12 deficient which obviously sent me into a spiral and made me feel like this was something that would get worse until my blood returned back to normal.”
4/5“For me, **Inositol + Niacin B3 + p5p** is the perfect stack for Anxiolytic effects.”
2/5 Taste & form“I don't take B vitamins except through additions to other supps like a ZMA capsule I take nightly, because b complex gives me anxiety.”
