Rhodiola Rosea

Useful for: Mild depression (again) and mental fatigue, although more studies need to be done. Research is mixed on whether it can also help with anxiety.

What’s the dose? Research has found that 340mg once or twice a day for at least six weeks may boost your mood and help you feel more emotionally stable. Take note: Look for a product that contains active ingredients in the concentrations that have been studied; that’s one with 3% rosavins and at least 1% salidrosides.
