Run down, stressed and overworked? Need more energy? Herbal "adaptogens" help the body to adapt to stress, increase mental alertness, improve work output and the quality of work produced under stressful circumstances.

Potency packed formulations to increase energy, concentration, enhance performance and boost the immune system.  Get the most out of life while also increasing your general health and the ability to perform under stress.

Stress often arises at the most difficult and busy times in life. Ginseng is a traditional herbal remedy that is widely used to help reduce the effects of fatigue, assist in enhancing stamina and endurance and maintain peak effort during times of high physical demand. When you are physically and emotionally stressed, ginseng helps to improve the body's stress-coping mechanisms, largely through its effects on the adrenal glands.

A new study tested the effect of regularly taking green tea extract (GTE) and found that over 10 weeks, endurance exercise performance was boosted up to 24% with 0.5% GTE supplementation, and 8% with 0.2% by-weight addition to food.

Reporting in the online edition of the American Journal of Physiology-Regulatory, Integrative and Comparative Physiology researchers at the Biological Sciences Laboratories of Kao Corp., Tochigi, Japan, said the 8-24% increase in swimming time-to-exhaustion was "accompanied by lower respiratory quotients and higher rates of fat oxidation."

The results "indicate that GTE is beneficial for improving endurance capacity.

Explaining the effects of the adaptogens is difficult, since they will influence each individual differently. If you are mentally exhausted or physically fatigued the adaptogens will help you feel more energetic, vitalized, and full of zest for life - but yet, they are not normal stimulants.

Should you however be stressed-out, or emotionally tired, and not coping with life the adaptogens will help you relax and make life easier to cope with, yet they are not tranquillizers and will not have a drug-like effect on the body.

The antioxidants contained in the adaptogens help the body fight free radicals which are released during the oxidation process of metabolism in the body, which can cause a variety of problems such as cell degeneration, cancer, ageing.

Products with multi ginsengs , greentea , and B vitamins are great for energy, stamina and stress.
