Nutritional Supplements Can Recover Optimal Mental And Physical Capabilities

By Arlean Boyles


There is some controversy about the use of nutritional supplements, with some experts claiming that we should get enough nutrients from our diets. Yet more and more people are suffering from various complaints and just do not seem healthy. Supplementing your diet with certain essential nutrients might be the answer to low level health problems.

Every year the soil on which crops are grown become increasingly depleted of many trace elements. While fertilizers can ensure bumper crops, the nutritional quality of the food produced is much lower than previously. Another issue is that modern waste disposal systems do not recycle nutrients to the soil, and for many years the fertility of the soil has been decreasing.

Vitamin D is essential for bone strength and immune function, as well as a range of other functions. While it is produced by the action of sunlight on your skin, the sun must be higher than 50 degrees in the sky for this to happen. If you need to supplement with this vitamin, make sure that it is the Vitamin D3 variety, or use a sun bed with UVB light, as UVA rays will increase your cancer risk.

Any supplements that you decide to take should be bioavailable, otherwise you are simply wasting your money. They need to be in a natural form so that your body can recognize and utilize them. Synthetic nutrients are often ineffective, even though they may be identical chemically. In some cases these synthetics can be actually be toxic, so it is worth while making sure you get the correct form.

When taking supplements, be careful not to overdose. While the usual official RDA is actually sub-optimal in most cases, dosages which are too large can have serious side-effects. For example, overdosing with vitamin D can cause extremely painful sunburn symptoms, and even result in death. Doses will be clearly indicated and should not be exceeded.

Anti-aging is attracting a lot of attention at the moment. This has made concentrated forms pf resveratrol and Astaxanthin extremely popular because of their proven benefits. Resveratrol can be found in chocolate, and in smaller quantities in red grapes or blueberries, while Astaxanthin is obtained in certain shellfish and salmon, but it is difficult to consume enough of these foods to get the full effects.

The point is that there are foods that provide all these natural substances, but concentrations are usually low. Bigger doses than are available naturally can have marked therapeutic effects, as long as certain limits are not exceeded. By eating organic food and taking nutritional supplements containing the right nutrients, you can achieve amazing vitality.
