Can Multivitamins Help With Stress? What the Science Says

A multivitamin can't remove the source of your stress, but it may help your body cope with it. Stress raises your need for certain nutrients, especially the B vitamins, vitamin C and magnesium, and research suggests that keeping those topped up supports mood and mental performance during demanding stretches.

Stress is a physical process as well as a mental one, and it uses up internal resources. This guide covers which nutrients are involved, what the evidence shows, and where a multivitamin fits.

How stress uses up nutrients

When your brain senses a threat, whether a work deadline or physical danger, it activates the hypothalamic-pituitary-adrenal (HPA) axis. That triggers the release of cortisol and adrenaline.

Making these hormones takes nutrients. The adrenal glands hold some of the highest concentrations of vitamin C in the body, and when cortisol rises, your need for vitamin C, vitamin B5 (pantothenic acid) and magnesium goes up. If they aren't replaced, your body may have a harder time switching the stress response off, which can leave you feeling tired but wired.

Stress also slows digestion, because your body puts "rest and digest" functions on hold. Even with a good diet, you may absorb fewer vitamins, so stress leads to depletion and depletion makes stress harder to handle.

B vitamins and your nervous system

The eight B vitamins help turn food into energy and are needed to make mood-regulating neurotransmitters such as serotonin, dopamine and GABA. Our article on B vitamins and the nervous system goes deeper.

Vitamin B6 is a cofactor for making serotonin, so without enough of it your body produces serotonin less efficiently. Vitamin B5 is sometimes called the "anti-stress" vitamin because of its role in adrenal function and hormone production.

B vitamins are water-soluble, so your body doesn't store much of them and you need them every day. Under pressure you use them faster, which is why many people notice a difference in mental clarity and energy from a supplement with a full B complex.

Magnesium

Magnesium is involved in more than 300 biochemical reactions and is best known for its role in relaxation and muscle function. In the brain, it acts as a gatekeeper for NMDA receptors, which handle excitatory signals. When magnesium is low, these receptors can become overactive, and you may feel restless and tense.

The link between magnesium and stress runs both ways. Low magnesium may make you more vulnerable to stress, and stress makes your body lose more magnesium in urine. Getting enough helps break that cycle.

Vitamin D and mood

Vitamin D acts more like a hormone than a typical vitamin. Its receptors are found throughout the brain, including areas involved in emotional regulation and depression, and research suggests it helps regulate the conversion of tryptophan to serotonin.

Deficiency is common. Forrest and Stuhldreher (Nutrition Research, 2011) found that about 41.6% of US adults are vitamin D deficient (below 20 ng/mL). Vitamin D receptors are also found on nearly all immune cells, and deficiency is associated with more infections and autoimmune conditions (Aranow et al., Journal of Investigative Medicine, 2011). Since chronic stress can suppress immunity, adequate vitamin D is useful on both fronts.

Vitamin B12

B12 maintains the myelin sheath that protects your nerves and helps make red blood cells. Running low can cause fatigue, brain fog and irritability, all of which make daily stress harder to handle.

Deficiency affects about 6% of adults under 60 and nearly 20% of those over 60, and vegans are at much higher risk, according to Allen and colleagues (American Journal of Clinical Nutrition, 2009). B12 comes mainly from animal foods, so if you eat a plant-based diet, rely on fortified foods or a supplement.

Stress and sleep

When cortisol stays high into the evening, it suppresses melatonin, the hormone that tells your body it's time to sleep, and poor sleep becomes another source of stress. Magnesium, vitamin B6 and vitamin D are all involved in making sleep-regulating hormones, so a shortfall can make it harder to wind down. See our article on stress, sleep and vitamins.

What about adaptogens?

Adaptogens are plant substances, such as ashwagandha and rhodiola, that are thought to help the body adapt to stress by balancing the HPA axis. They aren't vitamins, but some formulas combine the two. One way to think of it: vitamins supply the raw materials for the stress response, while adaptogens may act more like a thermostat. The evidence here is still developing.

Stress support for women

Shifts in estrogen and progesterone can affect how your body uses B vitamins and magnesium. In the luteal phase of the menstrual cycle (the second half), the need for vitamin B6 and magnesium often rises. Our women's multivitamin guide covers these needs in more detail.

Where Go Wise Multivitamin fits

Go Wise Multivitamin is a powder stick you pour onto your tongue, with no water needed and a natural berry flavor. Each stick has vitamins A, C, D3, E, B6 and B12, niacin, pantothenic acid, biotin, folic acid, zinc and chromium, plus elderberry extract and kelp as a natural source of iodine. It's vegan, gluten-free and has no artificial colors or flavors. It doesn't contain magnesium or thiamin. For those, see our magnesium glycinate and B-12 Complex. Every batch is third-party tested by Eurofins for heavy metals and microbial contamination, and it is made in a GMP-certified facility.

Pair it with the basics, such as regular movement, slow breathing and enough rest, and check with your healthcare provider first if you take prescription medication.

Frequently asked questions

Can multivitamins help with anxiety and stress?

Research suggests multivitamins may support your resilience to stress by replacing nutrients like B vitamins and magnesium, which are needed for neurotransmitter production and nervous system function. They are not a treatment for anxiety disorders, but evidence shows they can help keep mood and cognitive function steady during demanding periods.

How long does it take for supplements for stress to work?

It depends on your starting levels. Some people notice more energy and mental clarity within a few days of starting a B complex or magnesium. To correct a longer-standing deficiency, steady use over 4 to 8 weeks is usually recommended.

What is the best time to take vitamins for stress?

Most experts suggest the morning, with a meal. Food helps you absorb fat-soluble vitamins like D and E, and taking B vitamins early supports your energy through the day. If your supplement has a high dose of magnesium, some people find taking it in the evening helps them relax and sleep.

Can I take a multivitamin with my prescription medication?

Some vitamins and minerals interact with medications. For example, high doses of vitamin K can interfere with blood thinners, and magnesium can affect how well certain antibiotics are absorbed. Check with your doctor or another qualified healthcare professional before adding a supplement.

Why does stress make me crave certain foods?

Stress cravings are often your body looking for quick energy (sugar) or nutrients it's losing. A chocolate craving, for example, may be a sign your body is seeking magnesium. Getting a steady intake of vitamins and minerals may make these cravings less intense.
