This is a measure that can be useful in case of a nuclear accident.

In addition to these many virtues, sea moss is also very useful for regulating mood. Because it is rich in potassium, this seaweed acts on the nervous system. Studies have proven the effectiveness of potassium in the treatment of mental disorders such as depression, anxiety, or mood swings.

Thus, the consumption of drinks and products containing potassium is a good way to fight against this type of mental pathology. It is therefore highly recommended to take sea moss in these cases.
