8 Best Vitamins For Stress & Anxiety: Benefits, Dosage & More

Vitamin B7

Vitamin B7, also known as biotin, has been linked to lower levels of anxiety, stress and depression in adults (3). B7 is involved in the regulation of cortisol, which is also known as the stress hormone (5). B7 can also impact blood sugar levels, and low levels are linked with poor blood sugar control including raised fasting blood glucose levels (6).

If you eat a balanced diet with plenty of variety, you may get all the biotin you need. However, it is recommended that supplements are used and intake should not exceed 0.9mg per day (2).

Vitamin B9

More commonly known as folate (folic acid), research suggests that low levels of B9 is linked with higher rates of both depression and anxiety (7). Low levels of B9 are also more likely to increase the likelihood of mood disorders being treatment-resistant (8). B9 plays a role in a variety of brain activities, including neurotransmitter formation. It can also be broken down and used as short-term energy source.  

 Natural sources of folate include most dark and leafy greens, broccoli, chickpeas, and kidney beans.

It is recommended that adults have 200 micrograms of folate per day (2). However, if you are pregnant or trying to get pregnant then it is recommended to supplement with 400 micrograms per day (9).

Vitamin B12

Vitamin B12 is well known for its role in the maintenance of energy levels and immune system function. However, low levels of vitamin B12, also known as cobalamin, can lead to poorer brain health function. B12 is required for the formation and functioning of dopamine and serotonin and a deficiency in either of these hormones can be associated with low mood and increased levels of anxiety. B12 can be used to help combat these mood changes by supporting production of dopamine and serotonin (6).

B12 is found almost exclusively in animal products, including meat, fish and dairy products.

The recommended intake of vitamin B12 for adults is 1.5 micrograms per day (2). It is suggested that all vegans and vegetarians supplement daily with B12.  

Vitamin C 

Vitamin C is a potent antioxidant, which helps to reduce the damage from free radicals – toxins that cause inflammation within the body. Vitamin C has been shown to support the immune system by reducing the inflammation caused by free radicals and other stressors. Vitamin C has also been shown to reduce the side effects of stress, such as raised blood pressure and increased levels of anxiety (10)

Natural sources of vitamin C include citrus fruits, berries, and cruciferous vegetables such as broccoli and brussel sprouts. 

The recommended intake of vitamin C for adults is 40mg per day (11).

Vitamin D

Low levels of vitamin D are associated with poorer immune function and decreased energy levels. However, low levels of vitamin D are also associated with higher levels of depression and anxiety (12). Whilst the mechanisms behind this are not understood completely, it is suggested that vitamin D has anti-inflammatory properties. These properties may have a neuroprotective effect, leading to improved mental health and wellbeing (13).

Sun exposure is the main source of vitamin D – it is absorbed through the skin and processed in the kidneys and liver. However, due to low levels of sunlight it is recommended that everyone in the UK supplements with vitamin D from September to April.

The recommended amount of vitamin D for both adults and children is 10 micrograms per day, equivalent to 400 IU (14).

Vitamin E

Vitamin E is a powerful antioxidant that is often used in skincare to help prevent against damage from UV exposure. However, it has also been used as an adjunct therapy in patients with anxiety and/or depression, with some promising results (15). The benefits of antioxidants have already been touched on in this article; the anti-inflammatory properties of antioxidant fatty acids is the main mechanism behind improving mood.  

 Vitamin E is an essential fatty acid, and can be found in olive oil, vegetable oil, nuts, and seeds.

It is recommended that men need 4mg per day, whilst women need 3mg per day (16).
