If you've noticed yourself displaying some of the tell-tale signs of stress (we're looking at you, stress eating), then you might be hurriedly Googling the best stress supplements to help boost your calm.

Know this - we live in pretty stressful times and feeling frazzled is normal from time to time. That said, if you feel overwhelmed or like it's impacting your every day, it might be time to seek change.

While you could download a stress app or invest in an essential oil for stress, stress supplements promise to help you deal with stress from the inside out.

According to qualified nutritionist Lily Soutter, stress is a natural response which can be triggered by psychological issues, such as anxiety, or physiological causes, like a lack of sleep. "That said, our body can’t distinguish between the two causes of stress and responds in the same way by pumping out the stress hormone, cortisol."

So how do you know when stress has become too much? Good question. "If stress is chronic it can eventually lead to burnout, and while it’s not always possible to remove the source of stress, there are several ways we can manage stress more effectively," she explains.

That's where stress supplements come in, designed to help the biochemical processes in your brain which affect your mood. While they won't eradicate stress altogether, one 2013 study found that stress supplements reduced levels of perceived stress, boosting your everyday mood.

Not sure about the difference between stress vs anxiety? Our guide will help, as will our expert-led explainers on how to manage stress, how to reduce stress, and how to avoid burnout. For supplements to boost your zen - keep scrolling. 

What do stress supplements do?

While the verdict is still out on whether supplements can actually prevent stress in and of themselves, one thing research has proven time and time again is that general health will lower your likelihood of burnout.

Think about it: if you're experiencing a particularly stressful time at work, you're likely to be better equipped to handle the situation if you've slept well, eaten nutrient-dense food that makes you feel good, and taken some supplements that support both your body and mind.

As Soutter points out, the most effective ways of managing stress are often lifestyle techniques. "Think mindfulness, regular exercise, a healthy diet and even looking at supplements can enable us to have a healthier response to stress," she explains.

Nutri Advanced

Best magnesium supplement

Specifications

Number of tablets: 120 tablets

Recommended by: Qualified nutritionist Jenna Hope.

Good for: "Magnesium plays a vital role in over 600 processes in the body," explains Hope. "The stress response utilises a significant amount of magnesium which, in turn, can contribute to magnesium depletion, which is why supplementation can be beneficial."

She goes on to add that magnesium helps to support muscle and nerve relaxation and can help with reducing the effects of both stress and anxiety. Do note, though: "some magnesium supplements can contribute to changes in bowel movements, so always seek professional advice."

3. B-Complex

Bio Care

Best B vitamin

Specifications

Number of tablets: 30 tablets

Recommended by: Qualified nutritionist Jenna Hope and qualified nutritionist and naturopath Lauren Windas.

Good for: "B Vitamins play a vital role in energy production, which can often be zapped when we’re under intense periods of stress," explains Hope. 

Not only that, but when we're stressed, we tend to lose vital water-soluble B vitamins which we need daily to support vital processes such as manufacturing cellular energy and supporting the nervous system. "These vitamins contain methylated forms of B vitamins which are better absorbed and used by the body," shares Windas. This is particularly beneficial for those who have genetic variations in an enzyme called MTHFR, which means that they are unable to properly convert folic acid (the synthetic form of folate often found in B vitamin supplements), into the active form (methylfolate) which the body can actively use."

Bottom line: ensuring that you’re consuming adequate amounts of B Vitamins on a daily basis is vital for supporting energy and the stress response, concludes Hope.

4. Omega-3

Best Omega 3 supplement

Specifications

Number of capsules: 60 capsules

Recommended by: Qualified nutritionist Jenna Hope.

Good for: Did you know? "High levels of stress over a prolonged period of time can increase oxidative stress and inflammation in the body," shares Hope. 

That's where omega 3 comes in, which plays an important role in helping to reduce inflammation. That said, it can be difficult to get adequate amounts from the diet, particularly for those who don’t eat fish. "It’s important to be consuming plant sources such as flaxseeds, walnuts and seaweed, although a good quality supplement, like this one from Bodykind, can also play a role in supporting requirements during high levels of stress."

What are the best supplements for stress?

The three qualified experts we spoke to rate magnesium, ashwaganda, and B Vitamins for stress relief.

That said, as nutritionist Jenna Hope points out, supplements can interact with medications and if they’re consumed in excess can be dangerous, so do seek advice before starting supplementation. 

"It’s always important to seek professional personalised advice from your GP or healthcare professional," she shares.
