The best way to improve health is to be regular in your diet and try and eat maximum fresh things that mean no processed or junk or stored food stuff. In case you find that some deficiency has occurred due to some illness and which cannot be compensated with regular diet then in consultation with your physician you can some diet supplement.
The dietary supplement basically is any product which carries vitamins, minerals, enzymes, herbal medicine or a hormone which is primarily taken to augment the normal regular diet. The diet supplements come in the form of capsules, tablets, liquids and powder. They do make an effect on the health but as far as their safety or the level up to which they are potent remains questionable.
Preference should always be given to the normal regular diet but if need be then the priority should be medicinal herbs which are centuries old proven diet supplements. They are extracted from different herbs or plants and are used as preventive measures to a number of diseases and to improve the health too.
Herbal supplements has been being practiced since centuries and are used by the sick people or the old ones who face problem while having normal diet. Some commonly used herbs are saw palmetto, ginkgo and garlic etc. The medicinal herbs mostly originate from china and in some cases they use herbal teas also for cure and improvement of health related issues.
A number of supplements carry enzymes or hormones which are less produced by the body in case of sickness and the old age. People are of the opinion that such supplements are helpful in slow down the aging , or the Anti Aging effects ; or increasing the vitality but they are wrong as excessive use of such supplements may turn out to be harmful than to be beneficial. There is yet to be invented a supplement which can reverse the aging.
Amongst the women such diet supplements are advised especially during the prenatal or post natal phases. That is the time when most of the women does not feel like eating normal or the consumption within increases because of the fetus needs and consumption. During prenatal phase the nausea and heaviness restricts most of the women from taking normal regular diet and this tends causing weakness thus to compensate the weakness one does need some good food supplement.
Yet another kind of people who use such supplements are the ones who compete in any physical event like athletics, weight lifting, swimming etc. they use them to improve the physical strength, to increase exercise performance and to gain vitality with longevity to continue performing well. Mostly the food supplements used to improve health carry enzymes, hormones, proteins, fats, carbohydrates, glucose etc to make up the deficiency of these items in the body.
Nevertheless, healthly dietary habit is always best to follow. And before taking any supplements, it is always advised to seek the advise from your physician in case you have any doubts, as some unsuitable consumption may cause harm more than the benefit. Your physician knows better as to what does your body lack and how can that be compensated.
