For women, have a daily vitamin with high amounts of B vitamins (they need to be taken together for proper absorption) and iron. Iron is particularly important as it is bound to blood before circulating throughout the body. Given that women lose a significant amount of blood every month it is easy to see why low iron (anaemia) can lead to problems of tiredness and fatigue. Essential fatty acids are also important as they can reduce the symptoms of PMS significantly. Evening Primrose Oil, Vitamin E and Fish oils are all excellent. Turmeric and broccoli are also particularly important for women as they are anti carcinogenic and protect against breast cancer.
For men, it is important to maintain prostate health by increasing zinc intake. Saw palmetto has also been shown to be extremely useful for enlarged prostates. Maintain peak testosterone levels by cutting down on foods high in xenoestrogens (fake estrogens) such as steroid fed chickens. Again, B vitamins are needed for many of the processes within the body and are also useful for protection against stress.
