Vitamin D is the only vitamin that is not obtained from foods that are consumed. Instead, the D vitamin is actually obtained by sunlight on the skin.

There has been a lot of media coverage about the dangers of getting too much sun, but it is essential that the skin is exposed to sunlight to obtain the recommended daily allowance of the D vitamin. In reality, the amount of time that a person has to spend in the sun to receive a sufficient dose of the D vitamin is extremely small, about twenty minutes a day will be sufficient and not have any adverse effects from the amount of ultra-violet light received.

The most important function of vitamin D is to help control how much calcium is absorbed from food. The majority of the calcium is used to build strong teeth and bones, but it is also needed to send messages along the nerves and to help muscles, such as the heart muscles, to contract. It is the D vitamin that ensures that there is always sufficient calcium in the blood to perform these tasks.

Other functions that require the D vitamin relate to the immune system. It is believed that vitamin D is also a contributing factor in reducing the risk of contracting cancer and, in particular, colon cancer.

The variant of the D vitamin that is formed under the skin is known as vitamin D3, or cholecalciferol. This D vitamin is created when the ultraviolet in the sunlight reacts with a type of cholesterol that is found under the skin naturally. The D3 is converted into a more active form of the d vitamin in the liver and is then diverted to where it is needed the most. Some of the D vitamin remains in the liver and kidneys to help reabsorb the calcium from the blood. The rest of the D vitamin is dispersed to the bones to help them retain their calcium and the intestines to aid absorption of calcium from food.

Even though the majority of the D vitamin is formed through the exposure of the skin to sunlight there are some foods that do contain some of the vitamin naturally. This form of the D vitamin is known as vitamin D2, or ergocalciferol. This is used in the same way as the other D vitamins and is the type used to create the majority of D vitamin supplements.

Many people nowadays are turning to “organics” and “naturals” otherwise known as herbals. The rising popularity of herbal supplements has created a new fad, if not a new health lifestyle. But before you jump on the bandwagon, here are some things you need to know about this type dietary supplement.

What is the difference between a drug and a dietary supplement?

According to the definition set by food and drug administrations in different countries, drugs are chemicals that can prevent, prolong the life, treat other effects of a health condition, improve the quality of life, and/or cure ailments and diseases, or alter the function of any part or chemicals inside the body. These drugs have approved therapeutic claims. For example, paracetamol is a drug given to bring down the body temperature in fever. Ascorbic acid is indicated for the treatment of scurvy. Iron supplements are given to treat mild cases of anemia.

Herbal supplements are not classified as drugs but as dietary supplements. The main difference is that they do not have approved therapeutic claims unlike in the case of drugs. Moreover, dietary supplements could either contain vitamins, minerals, herbals, or amino acids, all aimed to add to or supplement the diet of an individual. They are not intended to be taken alone as a substitute to any food or medicine.

Most of the manufactured medicines we now have, once came from animals and plants. Through the years, chemists isolated the life-saving or life-curing components and separated them from the harmful ones. This lead to further drug research and drug development, which in turn lead to the production of a different variety of drugs for many ailments and conditions from synthetic sources.

But still we have semi-synthetic drugs, as well as drugs that more or less approximate more natural composition. Since herbal supplements are made from a mixture of crude herbs reduced into powder or gel form, and later packaged as tablets and capsules, there is a possibility that life-threatening or at least body chemistry-altering components are still present, thus the expression of concern from the medical community.

Is there a growing concern with the use of herbal supplements? YES

With the rising popularity of using and consuming anything herbal or organic, is the proliferation of fake herbal supplements that threaten to endanger lives. If that’s the case, then why are herbal supplements given drug administration approvals?

One way of ensuring the safety of the people is to have all candidate drugs, food, drinks, and dietary supplements registered with the proper authority. Otherwise, they would pose more risk with these things being sold in the black market for a hefty sum. We could ensure the quality and safety of herbal supplements if they get proper classification with the food and drug administration. Moreover, people may be able to file the proper complaints in the event a worsening of health condition is proven to be linked to the use of a particular herbal supplement.

Is using herbal supplements worth the risk?

Some say yes. It cannot be discounted that many who have tried herbal supplements experienced an improvement in their health—whether this is due to the herbals themselves or due to a placebo effect, as long as they do not worsen the condition of an individual, then using them is worth the risk. But of course, certain things must be considered before taking those herbal supplements:

Your doctor knows best.

First of all, clear your condition with your doctor. Ask him/her if taking a particular herbal supplement is safe given your health condition. People with heart, liver, or kidney trouble or malfunction, are usually not advised to take these, or at the minimum is to take these herbals in minimum amounts. All substances pass through the liver and kidney to be processed and filtered respectively.

Kava, which is used to relieve stress, has been pulled from the Canadian, Singaporean, and German markets because it contains substances that cause liver damage. Certain herbals such as Ephedra used for losing weight, contains chemicals with heart-inducing effects that can increase heart rate, which in turn can exhaust the heart. Ephedra caused heart attacks in several documented cases by the American Medical Association.

Follow the directions for use.

Never take more herbal supplements than what is directed by the doctor or as instructed on the bottle. Each individual reacts differently to the components of herbal supplements. While it is perfectly safe for one individual to take in a supplement of primrose oil capsules, another person may be allergic to it. So, do not take more than advised by your doctor or as instructed on the bottle.

Herbal supplements have no approved curative effect.

No matter how the product pamphlet or the label sounds (how it has been found to be helpful in certain health conditions), these herbal supplements are not therapeutic. So do not substitute these for the prescribed medications by your doctor for the treatment of certain diseases, or for the maintenance of blood pressure, lowering of blood sugar and cholesterol, and fight off infections.

In the end, you are the only one who can make the determination as to whether you choose supplements or not. By reading reports and studies, advice from medical professionals and using good judgment, you can weight the pros against the cons and make an informed decision. Here’s to better health.
