You hear a lot about the benefits of ginkgo biloba and green tea supplements. Ginkgo increases the amount of oxygen in the brain. Green tea sees to improve alertness, although there is no certain explanation for that effect. Neither of these supplements has undesired side effects, as long as the manufacturer does not add caffeine to the mix. That's what you typically see in products designed as weight loss aids.
There is evidence to indicate that green tea reduces the risk of certain types of cancer, enough evidence that it is considered a valid health claim. A reduced risk of prostate and breast cancer is considered a verifiable claim, as there is more evidence for those two types. But, some studies have shown a reduction in stomach and throat cancer, as well. A reduced risk of heart disease is another well known benefit.
It just makes sense to do as much as we can to reduce our risks of heart disease and cancer. They are our two biggest killers. But, is taking ginkgo biloba and green tea, enough?
Recent studies indicate that vitamin D and calcium reduce the risk of cancer, too. There is a great deal of evidence to indicate that resveratrol, an antioxidant found in red grape skins, reduces the risk of heart disease, by prolonging the life of heart cells. Unlike other cells of the body, heart cells do not regenerate when they are damaged.
One of the factors that contribute to heart disease is unhealthy cholesterol levels. It has been noted that low levels of HDL or good cholesterol and high levels of LDL or the bad type is a risky combination. When things are in balance, HDL carries LDL away from the heart and returns it to the liver for reprocessing. If things are not in balance, LDL cholesterol builds up on the interior walls of the arteries, making the heart work harder and increasing the risk of blood clots.
Ginkgo biloba and green tea can help reduce unhealthy cholesterol levels, but so many many other nutrients. There is no single nutrient that is more important than any other. They all work together.
There are monetary considerations, as well. Single ingredient supplements do not provide the best value for your money. Multi-nutritional supplements that contain a variety of extracts provide the best value and you do not have to worry about unwanted interactions, if the supplements are well designed.
Most of the multi-vitamins on the market contain synthetic vitamin E and other additives that are not good for your health. Some of the ginkgo biloba and green tea supplements on the market are not standardized. You do not know how much of a good thing you are getting. You do not know about the bad effects that contaminants and chemicals could have on your health. The only way to be sure is to buy an all-natural supplement.
The manufacturer should check each raw ingredient like ginkgo biloba and green tea for contaminants. If they guarantee purity and potency, then you have likely found a good product.
