You might also have asked yourself: “Is there a vitamin that calms you?” or “what supplements can ease anxiety?”.

With this in mind, here’s a curated line-up of slow Sunday essentials from iHerb to help you create your most relaxing weekend yet.

Which vitamins are good for relaxing?

Several nutrients are commonly associated with supporting relaxation and emotional balance:

• Magnesium contributes to normal psychological function and the reduction of tiredness and fatigue.

• L-theanine is often used in food supplements designed to promote relaxation without drowsiness.

• Ashwagandha is traditionally used in herbal practice, and research suggests it may help the body respond to everyday stress.

• Probiotics are increasingly studied for their connection to the gut-brain axis and mood.

While research is ongoing, these supplements may support a calm routine when combined with good sleep, balanced nutrition and stress-management habits.
