Two astragalus or cat's claw (or combination) tablets each morning with breakfast. Continue for six to twelve months.

Coenzyme Ql 0 - a high dose of 100-200 mg needs to be taken daily for at least six to twelve months. It is the only natural substance that has been found through testing to revive the body after chronic fatigue. I now encourage men who have long working hours, travel commitments and stress to take this enzyme daily to prevent exhaustion and to give them more vitality and energy.

An anti-oxidant tablet, two per day.

One multivitamin B tablet with B12 and folate twice a day.

One Siberian ginseng tablet twice a day (optional), to help the body cope with stress.

Schisandra (Schisandra chinensis)

This herb is vital for enhancing the wellbeing of men. In the Chinese medical system, schisandra is regarded as one of the great anti-oxidant herbs with an amazing ability to detoxify the liver and relieve mental fatigue. As a herbalist, I always include this herb with St Mary's thistle for men who have a high workload and who overload their systems with unhealthy food and alcohol. Check with your herbalist for the most suitable dosage.
