Examples Nutritiinal product problems HbAc test foreign objects in the packaging or other apparent quality defects.

For most claims made on product labels, the law does not require evidence that the claim is accurate or truthful.

In fact, the FDA's first opportunity to weigh in comes only after a product is marketed, when it can take action against products that are adulterated, misbranded, or likely to produce injury or illness. Since nearly all supplements are used without medical supervision or monitoring, most of the estimated 50, adverse reactions that occur in the United States each year go unreported.

If a supplement's label or ads won't give you reliable information, how can you find out if a supplement can help — or, for that matter, hurt? Although it's a slow process, careful, objective medical studies provide the guidance that counts.

In most cases, scientific investigations of supplements start with simple observational studies, in which researchers compare the health status of folks who take a particular supplement with the health of people who don't take the supplement. It's an important effort, but the results don't always hold up.

So the next step is to conduct randomized clinical trials, in which volunteers are assigned by lot to take either the supplement or an identical-looking placebo "dummy pill" while researchers track their health.

In the best studies, neither the volunteers nor the researchers know who is getting the real thing until the code is broken at the end of the trial. Everyone wants to know if supplements can help. It's a good question. Here's where we stand today — but you should keep an eye out for new results, since recommendations will change as scientific studies trickle in.

Unfortunately, in most cases, the studies have failed to confirm our hopes, though there are exceptions. Many people take supplements in the belief that they will preserve health or ward off illness; many others use supplements in an attempt to treat specific conditions that have already developed.

We'll have a look at popular supplements in both categories, starting with preventive supplements used principally by healthy people. Vitamin D. To get vitamin D the old-fashioned way, by producing it in the skin, we need lots of sunshine. But as work has shifted from the farm to the office and as we've learned to use sunscreens to reduce the risk of skin cancer and wrinkles, many people lack sufficient amounts of the "sunshine vitamin.

Vitamin D is needed to absorb calcium from the intestines; that's why vitamin D is so important for healthy bones. Current guidelines call for IU international units a day below age 71 and IU a day thereafter. But many experts recommend to 1, IU a day for most adults; daily doses up to 4, IU are considered safe, but more can be toxic.

It's very hard to get the vitamin D you need from your diet; oily fish and fortified dairy products are the only important sources.

So supplements do make good sense for most adults. The form known as vitamin D 3 is usually recommended, but D 2 is also effective; for best results, take your vitamin D along with a meal that has some fat.

If you want to be sure you need this supplement, ask for a blood test; levels of at least 30 nanograms per milliliter are considered best. Vitamin E, vitamin A, beta carotene, and vitamin C were the favorites of the s and early '90s. In May , the EFSA Panel on Food Additives and Nutrient Sources Added to Food ANS adopted guidance on the evaluation of sources of nutrients and bioavailability A term to describe how much of a substance gets into the blood through a variety of routes, including the diet.

It may refer to vitamins, additives, pesticides or medicines. of nutrient from the sources. In December , EFSA published the Summary report on Dietary Reference Values for nutrients.

Earlier in , EFSA published the Overview on Tolerable Upper Intake Levels as derived by the Scientific Committee on Food SCF and the EFSA Panel on Dietetic Products, Nutrition and Allergies NDA. EFSA carries out the safety assessments of six substances used as ingredients in food supplements, for which safety concerns were raised either by the EC or Member States, namely: Ephedra species , Yohimbe Pausinystalia yohimbe K.

The mandate of the EFSA NDA Panel is broadened to include the assessment of nutrient sources and requests for safety assessment under Art. The EFSA NDA Panel publishes an opinion laying down the general principles for establishing Dietary Reference Values DRV Dietary reference values DRVs are the complete set of reference values for nutrient intake comprising Population Reference Intakes PRI , Average Requirements AR , Adequate Intakes AI , Lower Threshold Intakes LTI and Reference Intakes RI.

DRVs are typically used as a basis for reference values in food labelling and for establishing food-based dietary guidelines. and started the review of DRVs for macro and micronutrients established by the Scientific Committee on Food in EFSA and the Scientific Committee on Food SCF compile all opinions identifying possible adverse health effects of individual micronutrients at intakes in excess of dietary requirements and, where possible, establish tolerable upper intake The amount of a substance e.

Between and , EFSA carried out a comprehensive assessment of substances that are permitted to be used as sources of vitamins and minerals in food supplements in the EU.

The assessment included both the evaluation of the safety of a nutrient source at the intake levels suggested by the applicant, and the bioavailability of the nutrient from the source i. the effectiveness with which the mineral or vitamin is released into the body.

Companies wishing to market a nutrient source not included in the permitted list have to submit an application to the European Commission.

Moreover, EFSA has performed a comprehensive evaluation of the possible adverse health effects of individual micronutrients at intakes exceeding the dietary requirements and, where possible, established tolerable upper intake levels ULs for different population groups.

ULs represent the highest level of chronic daily intake of a nutrient that is not likely to pose a risk of adverse health effects to humans. Throughout this work EFSA provides support to the European Commission in establishing maximum limits for vitamins and minerals in food supplements and fortified foods.

Under the circumstances described in Art. Responsibility for the safety of these products lies with the food business operator placing the product on the market.

EFSA provides scientific opinions to support the evaluations carried out by the European Commission. The directive lays down the rules applicable only to the use of vitamins and minerals in the manufacture of food supplements.

The use of substances other than vitamins or minerals in the manufacture of food supplements may be governed by national rules or may be subject to other specific EU legislation.

Finally, as with all the other food products, food supplements may contain additives e. sweeteners, colours, coating agents. Because food supplements are considered as food, it is the responsibility of the manufacturer, importer, supplier or distributor to ensure that a food supplement placed on the market is safe.

Before buying or taking a dietary supplement, talk with a health care professional—such as your doctor, nurse, registered dietician, or pharmacist—about the benefits and risks. Many supplements contain ingredients that can have strong effects in the body.

Fine grooves ensure that the body and cap are tightly sealed, meaning that the capsule cannot fall apart into its two halves and the powder cannot escape through the seam.

Capsule shells exist in various sizes. These are internationally standardised. When it comes to dietary supplements, sizes 1, 0, through to 00 are most commonly used. Depending on the density of the powder, hard capsules can generally contain between and mg of material.

Hard capsules can be made from various basic materials. The most important of these are gelatine, and HPMC hydroxypropyl methylcellulose as a vegetarian alternative. Even organic products can be developed with hard capsules as, according to Annex VIII of Regulation EC No.

This is something which is guaranteed in, for example, nature caps®. Soft capsules are particularly well-suited for oils, emulsions or other similar materials up to a paste-like consistency. Unlike the two halves of a hard capsule, these capsules are not prefabricated. The material which is to be placed inside the capsule is then enclosed in two equally-shaped capsule shells which are tightly sealed with a seam.

These capsules have a small extension which can be manually twisted off. This means that the material inside the capsule can be emptied and consumed through the thus created opening — without also having to consume the capsule. A wide range of sizes is also available, whereby filling quantities of around mg tend to represent the upper limit of what a person can reasonably be expected to swallow.

Soft capsules can be made from gelatine or come from a vegetarian source, e. on the basis of carrageenans. Carrageenans are a group of long-chained carbohydrates polysaccharides which can be found in the cells of various species of red algae.

The shells of both hard and soft capsules can be kept transparent for an appealing look, can be made opaque using titanium oxide, or can be dyed a variety of colours. An opaque capsule shell offers the contents additional protection from light. Generally, non-chewable capsules considerably undercut the disintegration time of 30 minutes prescribed by the European Pharmacopoeia.

Gelatine capsules contain a certain percentage of moisture. This can lead to undesirable interactions with very hygroscopic ingredients, such as magnesium oxide or tannins. Hygroscopic powder deprives gelatine capsules of their necessary residual moisture. This makes the capsule shell brittle and fragile.

This is something to be inherently kept in mind when developing the formula for a capsule. The biggest advantages of capsules is that they can be filled without any or with relatively little pressure.

Medications are regulated by the FDA. Before a prescription or over-the-counter drug can be sold in the United States, the manufacturer must submit data supporting its safety and efficacy, and after the medication is approved, the FDA continues to monitor adverse reactions. Even with all these safeguards, problems still occur, prompting the FDA to withdraw many medications and to require strong warning labels on others.
