There was a time when the pharmacist was also a craftsman. In the back room of the pharmacy, he selected raw materials, weighed them, combined them, and prepared customized remedies for each person. This was the galenic tradition: knowledge based on hands-on work, understanding of plants, and attention to the individual. If you've ever wondered what connects that world to what we now call nutraceuticals, you're in the right place.
The way we take care of our well-being has changed profoundly. It's no longer enough to rely on a generic solution: those who choose a supplement today want to know what it contains, where the ingredients come from, and what evidence the formulation is based on.
Nutraceuticals originate precisely from this, from the meeting between the ancient wisdom of plant extracts and the rigor of modern research. In a market increasingly crowded with products and promises, knowing how to distinguish a scientific approach from a fleeting trend becomes a valuable skill.
Below, we will explore together the true meaning of nutraceuticals, the difference between nutraceuticals and pharmaceuticals, the comparison between natural nutraceutical supplements and synthetic ones, and the concrete criteria for choosing them consciously.
Nutraceuticals: definition, origin of the term, and true meaning
If you've asked yourself "what are nutraceuticals", the answer starts with a word coined in 1989 by American physician and researcher Stephen DeFelice. DeFelice combined two terms - nutrition and pharmaceuticals - to describe a new discipline: the study of food-derived substances which, taken in concentrated form, can contribute to maintaining physiological well-being.
This is not about self-medication, nor an alternative version of phytotherapy. Nutraceuticals have a precise scope: they start from compounds present in foods - polyphenols, vitamins, proteolytic enzymes, minerals - and study them with scientific methods to understand how, at what dosage, and in what form they can support the normal functions of the body. The boundary with the pharmacological world, as we will see shortly, is clear and regulated.
In the Italian landscape, the food supplement sector has reached significant maturity. Italy is the leading European market by turnover in the supplement sector, and the public is increasingly oriented towards products with traceable ingredients, studied formulations, and scientific evidence supporting the declared benefits.
Nutraceuticals and functional nutrition: two concepts not to be confused
Often nutraceuticals and functional nutrition are used synonymously, but they indicate two different levels.
Functional nutrition deals with the health properties of foods as you consume them at the table: tomatoes rich in lycopene, oily fish with their omega-3 fatty acids, pomegranates with their anthocyanins. When you eat a whole pomegranate, you take in a set of bioactive compounds in the concentration that nature intended for that fruit.
Nutraceuticals go a step further: they isolate and concentrate bioactive compounds - polyphenols, punicalagins, ellagic acid - and make them available in targeted formats such as sachets, tablets, or capsules.
It's one thing to drink pomegranate juice; it's another to take a standardized extract like PunicaPLUS®, where the concentration of polyphenols has been standardized through a controlled extraction process. The matrix is the same, but the density of active compounds and the reproducibility of the dosage change substantially.
Nutraceuticals and pharmaceuticals: differences, boundaries, regulations, and purposes
The difference between nutraceuticals and pharmaceuticals deserves a clear answer. The two fields share an interest in human health but operate on distinct tracks in terms of purpose, regulatory framework, and type of evidence required.
Purpose
A drug is designed to treat, cure, or prevent a specific pathology.
A nutraceutical supplement has a different goal: to support the maintenance of physiological well-being. The B vitamins contained in a supplement like Improve Energia, for example, contribute to the reduction of tiredness and fatigue - a physiological, not therapeutic, action.
Regulatory framework
Drugs follow an authorization process managed by bodies such as AIFA and EMA, with large-scale clinical trials and a complex registration dossier.
Nutraceutical food supplements fall within the scope of food legislation: EC Regulation 1924/2006 governs nutrition and health claims, EU Regulation 432/2012 lists approved claims for functional ingredients, and at the Italian level, Legislative Decree 169/2004 defines their specific framework.
One point must be emphasized without ambiguity: a food supplement cannot in any way replace pharmacological therapy, nor a varied and balanced diet and a healthy lifestyle. Its role is complementary and fits within a conscious and guided approach to well-being.
Nutraceuticals in daily well-being
Nutraceuticals have become part of the habits of millions of people for several reasons. The first is demographic and cultural.
We live longer, and the focus has shifted from the mere absence of disease to quality of life in the long term. Healthy aging is no longer a slogan but a concrete goal that guides daily choices, from diet to physical activity, from targeted supplementation to stress management.
The second is scientific literacy.
Today's public does not accept vague promises. They want to read the ingredient list, understand what a supplement contains, and check if the company publishes scientific resources to support its formulations. Trust is built through transparency, not slogans.
The third is related to contemporary lifestyles.
Intense days, little time for balanced cooking, periods of prolonged stress, and decreases in energy and vitality: all this can lead to specific nutritional deficiencies that a daily diet, however careful, struggles to fill. This is where a well-formulated nutraceutical supplement can act as targeted support.
The role of food awareness
The deepest change concerns mindset. For some time, well-being was perceived as a reaction to an already present problem: I feel tired, I look for a remedy. Today, the approach has reversed, and nutraceuticals are a direct expression of this.
Supplementing where needed, before a deficiency becomes a perceived discomfort, is an act of daily attention to one's well-being.
Just observe the profile of the informed consumer: they read labels, compare ingredients between different products, and look for the difference between a generic "vitamin complex" and a formulation with standardized extracts and specific dosages.
It's not enough to know that a supplement contains magnesium: they want to understand in what form - citrate, oxide, bisglycinate - and why one form is preferable to another. The wellness guide that each person builds for themselves also comes from these conscious, daily, and informed choices.
Natural vs. synthetic supplements: what's the difference?
Let's address the doubt that many people carry when browsing shelves and online catalogs. Natural nutraceutical supplements and synthetic supplements: what is the real difference? And above all, is one "better" than the other?
The distinction is not about moral judgment between "good" and "bad," but between two formulation approaches, each with its strengths and limitations.
To navigate correctly, it is important to make a preliminary distinction. A totally natural supplement is a product whose composition consists entirely of ingredients from the plant, animal, or mineral world, without synthetic components. It is different, however, to speak of ingredients of natural origin: in this case, it refers to the individual components of the formula that derive from nature, within a supplement that may still include other technical elements (such as excipients, flavorings, or anti-caking agents) necessary for the stability and usability of the finished product.
Given this premise, supplements with ingredients of natural origin start from plant or food matrices (fruits, plants, roots) and extract their bioactive compounds with the aim of preserving the phytochemical profile of the raw material. A pineapple extract, for example, does not only contain isolated bromelain: it carries a set of enzymes, flavonoids, and organic compounds that work synergistically in the plant.
The formulations of our Flomel line, for example, follow this logic, combining bromelain and hesperidin from Mediterranean citrus fruits with dehydrated pineapple juice.
Synthetic supplements, on the other hand, reproduce the molecular structure of a single nutrient in the laboratory. A synthetic vitamin C is chemically identical to the one you find in an orange (the molecule is the same).
The advantage lies in absolute standardization and lower production costs.
Modern nutraceuticals tend to value natural origin not for ideological reasons, but because a well-formulated plant extract retains a biochemical complexity that an isolated molecule cannot replicate.
And here a concept worth exploring comes into play: the phytocomplex.
Phytocomplex and synergistic effect: the added value of plant extract
When you take a quality plant extract, you are not taking a single isolated active ingredient, but a phytocomplex: a coordinated set of compounds - polyphenols, flavonoids, organic acids, tannins - which in the original plant perform interconnected functions and which, once extracted, continue to enhance each other.
Take the case of pomegranate extract.
The pomegranate fruit is not "rich in antioxidants" in a generic sense: it contains a specific family of compounds (punicalagin A and B, ellagic acid and its derivatives) that act on different but complementary biochemical pathways. Punicalagin has a recognized antioxidant action; ellagic acid and its derivatives complete the antioxidant profile of the extract; polyphenolic derivatives complete the picture with a synergistic action that none of the individual molecules, taken alone, could match.
The PunicaPLUS® extract - used in the formulations Improve Energia, Improve Magnesio, and Improve Idratazione - contains numerous identified bioactive compounds and is derived from the whole fruit of the Mediterranean pomegranate.
It is a concrete example of how the phytocomplex is preserved and standardized through advanced extraction technologies, maintaining a compound profile that in nature works like an orchestra, not a soloist.
When synthesis is necessary and when nature has more to say
It would be incorrect to state that a natural supplement is always preferable to a synthetic one, or vice versa. When the goal is to remedy a documented deficiency of a single vitamin, what matters is the molecule taken and its dosage, regardless of the source. Vitamin C, for example, can be obtained either synthetically or from plant extracts rich in the nutrient - such as acerola or rosehip - and the biological effect on the body's needs is comparable.
In other cases, however, a standardized natural extract has a richer and more articulated functional profile.
If your goal is not to correct a single deficiency but to support a complex physiological function, such as energy metabolism, drainage of bodily fluids, or immune system function, a well-formulated phytocomplex acts on multiple fronts simultaneously.
And then there is a third way, which is probably the most interesting: integrated formulation.
Many modern nutraceutical supplements combine natural extracts and selected nutrients in the same formula, thus combining the complexity of the phytocomplex with the precision of vitamin dosage.
Improve Energia, for example, combines PunicaPLUS® pomegranate extract with B vitamins and vitamin C, each with a specific role in contributing to the reduction of tiredness and fatigue. This is not a random sum: it is a reasoned formulation design, in which each component has a defined function.
How to recognize a quality nutraceutical supplement: 7 practical criteria
So far we have talked about concepts and principles. But when you are in front of a shelf - physical or digital - how do you evaluate the quality of a supplement before buying it?
Here are seven concrete criteria you can check independently by reading the label and product sheet:
- Transparency of the ingredient list. The list must be complete, legible, and in descending order. Each ingredient must be indicated with its specific name (e.g., "bromelain 2500 GDU/g from Ananas comosus (L.) Merr., stems"), not with vague terms such as "enzyme blend". The indication of the botanical source, the part of the plant used, and the enzymatic activity is a legal requirement.
- Information on the standardization of extracts. Standardization represents an important and reliable parameter, ensuring that the supplement contains a constant and defined amount of bioactive compounds in all batches. Reading the standardization data in the nutritional content table or in the ingredient list offers the consumer useful additional information to understand the level of product standardization.
- Communication of the production chain. Supply chain traceability is an obligation under European law, which requires all food business operators to be able to reconstruct the path of a raw material from the field to the finished product. The added value, from the consumer's point of view, lies in companies that choose to make this production chain transparent to the outside world, explaining the origin of raw materials, processing methods, and partners involved in the process.
- Consistency between label and communication. Compliance with EFSA-authorized claims is a mandatory requirement for any supplement on the European market: it is therefore not a distinguishing feature. However, the careful consumer can look beyond the label, observing whether the company's collateral communication (website, social media, information materials) also remains consistent with the scope of approved claims.
- Suitability of the formulation for one's needs. Every supplement contains, in addition to functional ingredients, certain excipients necessary for the stability, processing, and usability of the product. Their quantity and type depend largely on the pharmaceutical form chosen: a tablet, for example, requires technical components for compression and disintegration that a powder sachet does not. Rather than evaluating the number of excipients (an operation that would require specific technical skills), the consumer can verify that the formulation is compatible with their dietary needs: absence of gluten, lactose, specific allergens, suitability for vegan or vegetarian diets.
-
Clarity of instructions for use. Dosage, frequency, time of day to take the supplement: everything must be clearly indicated. The label must also include standard warnings, including the recommendation not to exceed the recommended daily dose and to keep the product out of the reach of children under 3 years of age. It goes without saying that supplements do not
replace a varied and balanced diet.
- Availability of scientific evidence. A company that invests in scientific research and development and is committed to formulating its products based on scientifically supported ingredients demonstrates a focus on quality that goes beyond marketing.
Standardized extracts, bioavailability, and production standards: the key terms to know
When comparing supplements, you will encounter technical terms that may seem difficult but, once understood, become the best tools to navigate the market.
Standardized extract means that the plant extract has been analyzed and its concentration of active compounds has been precisely determined. For this information to have real value, the standardization must always be accompanied by the specific percentage: reading "pomegranate extract standardized to 40% in punicalagins" is very different from finding only the wording "standardized in punicalagins", which alone quantifies nothing. It is the numerical data that makes the information actually usable, distinguishing a standardized extract from a generic "pomegranate powder", where the variability between batches can be significant.
Bioavailability is the parameter that describes how much of a compound, once ingested, is absorbed by the body and made available to perform its action. Two supplements may contain the same amount of magnesium on paper, but the actual amount absorbed can vary significantly.
Production standards. All food business operators are legally required to apply the HACCP (Hazard Analysis and Critical Control Points) system, the mandatory European protocol for hygienic-sanitary production safety. Some companies choose to go beyond this requirement, voluntarily adopting more stringent production standards - such as GMP (Good Manufacturing Practices), originally developed for the pharmaceutical sector - which provide for even more rigorous quality control, hygiene, and traceability protocols at every stage of the process, from the receipt of raw materials to packaging.
Extraction technologies and innovative formulation: what "natural" means today
There is a misconception worth clarifying once and for all: "natural" does not mean rudimentary. A supplement can have a completely natural origin and at the same time be the result of sophisticated extraction technology. Indeed, technology makes the difference between a handmade product and a reliable nutraceutical supplement.
Modern extraction techniques - concentration, purification, standardization - transform a plant raw material into a standardized extract with a defined and reproducible profile of bioactive compounds.
Take the case of PunicaPLUS®: the pomegranate is harvested, the whole fruit is processed, and through a controlled extraction process, a dry extract with numerous identified bioactive compounds is obtained.
Frequently Asked Questions (FAQ)
Below are the answers to the most common questions.
What is nutraceuticals?
Nutraceuticals is the discipline that studies and applies substances of food origin - such as polyphenols, vitamins, minerals, and enzymes - which, taken in concentrated form and at specific dosages, can contribute to maintaining physiological well-being. The term was coined in 1989 by Stephen DeFelice and arises from the fusion of "nutrition" and "pharmaceuticals".
What is the difference between a nutraceutical supplement and a drug?
The distinction is based on purpose: a drug is intended to prevent or cure a pathology; a nutraceutical supplement supports the maintenance of physiological well-being. The two areas follow different regulations and have complementary, not overlapping, roles. A food supplement cannot in any way replace pharmacological therapy.
Can food supplements replace medicines?
No. Food supplements should not be understood as substitutes for pharmacological therapy, nor for a varied and balanced diet and a healthy lifestyle. Their role is complementary and supportive. It is always recommended to consult your doctor or specialist before starting any supplementation, particularly in the presence of specific conditions or ongoing therapies.
When should I consult a doctor before taking a supplement?
It is always advisable to consult your doctor or specialist before starting supplementation, especially during pregnancy, breastfeeding, ongoing pharmacological therapies, diagnosed pathologies, or if the product is intended for children. For children under two years of age, any product that does not have specific indications for pediatric use should only be used after consulting the pediatrician.
