One important thing to consider is consulting your doctor before taking any food supplement in general and before taking probiotics in specific. If you are suffering from any specific health condition, whether recent or chronic, than only you doctor would be able to assess if the probiotic would actually be of any benefit to you or would it complicate anything for you. Therefore, unless your doctor is advising you to use a specific probiotic to treat a condition, you must try to stick to your daily dietary routine and fortify it by consuming your vitamins and minerals from natural sources such as greens and fruits.
It is known that no supplement including best probiotic supplement cannot offer the same health benefits which come with the use of natural fruits and vegetables, some of which are also enriched with probiotic properties such as asparagus, banana, berries and oatmeal to name a few.
Research indicates that not all probiotics are equal and effective for everyone. Similar to medications, these products may produce varying effects on different people therefore they should not be considered to be taken as regular multivitamins. We need to remember that a human body contains varying level of different bacteria which are in place in a specific balance and is unique for each person. While taking probiotic may solve a mild stomach condition for you, it may disrupt the balance of pre-existing good bacterium in your body which could cause a negative effect on your overall health.
Most supplements including probiotics are usually considered a quick fix to a problem. While it does work to provide short term relief to a condition, its prolonged usage should be carefully assessed and evaluated by a qualified health care professional. It has been noticed that some supplements do not work effectively or could cause harmful effects on the body if they are taken in conjunction with other medicines.
