Nutritional supplement dosage -
When it comes to dietary supplements, these should also be a feast for the eyes. An attractive product leads both to good acceptance and compliance among consumers. Good compliance ensures not only regular intake of the supplements, but can even contribute towards the body being better able to absorb the nutrients these provide.
When it comes to pharmaceutical products, it has been proven that the bioavailability of the active ingredients is higher when the patient has a positive attitude towards their medical therapy.
In addition to the sensual components, the form of dosage also influences technical characteristics such as shelf life, as it can provide protection against light and air. There are many different forms of dosage, which we shall briefly present in this article as an overview.
Hard capsules are particularly well-suited for vitamins and minerals, as well as plant powders and powdered extracts. They consist of two prefabricated halves. 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. Putting thermal stress on the nutrients is another aspect which can be kept to a minimum or avoided entirely.
For example, many people prefer fish oil capsules whose surrounding capsule shell prevents the oil from coming into direct contact with the oral mucosa, or hard capsules which encase active substances with healthy bitter substances, thus lending them a form which can be easily ingested.
Sometimes, creating a formula for a tablet which is technically optimal requires a complex development process. However, tablets do allow for some variations which a capsule does not offer. Effervescent tablets or tablets with a breakline which allow for them to be broken into smaller pieces are just a few examples.
Coatings are another aspect which can be easily implemented among tablets, whether for optical and technical reasons, or to ensure the gastro-resistance of the tablet. 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.
nutrient or chemical that is ingested by a person or animal via the diet. levels UL for different population Community of humans, animals or plants from the same species. 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.
Member States may, for monitoring purposes, request notification of the placing on the market in their territory of a food supplement. Once the product is on the market, the competent authority of the Member State may monitor its use in that territory.
List of competent authorities of the EU Member States. vitamin C, calcium. Annex II of the same directive contains a list of substances that are authorised as source of the vitamins and minerals listed in Annex I e. sodium-L-ascorbate as a source of vitamin C, calcium lactate as a source of calcium.
The use of ingredients other than vitamins and minerals e. botanicals in the manufacture of food supplements may also be authorised under other specific legislations depending on the nature of the substance e.
novel foods , substances for the fortification of food , foods for specific groups. Substances not falling in the above categories may still be found in food supplements present on national markets subject to provisions in the specific national legislations.
In addition to the substances added for nutritional purposes, food supplements may also contain food additives, i. substances added to the products for technological reasons e. coating agents for tablets, sweeteners. There are at present no binding maximum and minimum levels for the ingredients of food supplements defined in the European Union.
Due to the complex nature of the issue and the divergent views expressed by the parties involved, this process is ongoing and no final conclusion has been reached. The activities of EFSA in establishing tolerable upper intake levels ULs of individual micronutrients for different population groups provide support to the European Commission in establishing maximum limits for vitamins and minerals in food supplements and fortified foods.
These include:. In addition, presentation and advertising must not attribute to food supplements the property of preventing, treating or curing a human disease, or refer to such properties. The European Commission, on its own initiative or on the basis of information provided by the Member States and following an assessment by EFSA, may take a decision to include a certain substance in a list of substances whose use in foods is prohibited, restricted or under scrutiny.
This may happen when the addition of a substance in food products increases its exposure Concentration or amount of a particular substance that is taken in by an individual, population or ecosystem in a specific frequency over a certain amount of time.
