Background: Within the last years, excessive utilization of food supplements for prevention and prophylaxis in different chronic diseases is observed. In order to extend the control on the arrangement of the market, utilization, and safety of food supplements, the European Commission took genuine regulatory steps to harmonize the criteria for FS and to guarantee that they are not giving deceiving information. However, excessive use, uncontrolled patients consumption, exposure to higher than recommended intakes, and even interaction with specific medicines can cause toxicity risks and pose serious health concerns. The aim of this study is to examine the tendency of pharmacists to correctly recommend food supplements to chronically ill patients in order to extend the pharmaceutical care and prevent side effects.
Materials and methods: The used method is an anonymous survey that was conducted by using the direct questionnaire method among master pharmacists and assistant pharmacists working in community pharmacies in Bulgaria.
Results: The results show that the majority of the pharmacists are willing to recommend food supplements and that they could participate in the monitoring of chronically ill patients with food supplements intake. On the other side, the survey shows that most of the patients are seeking for food supplements and do ask for advice.
Conclusion: In conclusion, pharmacists as the most accessible health care professionals can provide more detailed information concerning food supplements in order to avoid negative effects on the safety of chronically ill patients, especially with additional training in the field.
pharmacists, food supplements, interactions, knowledge, risk
Food supplements (FS) placed on the market in a European Union (EU) Member State must comply with all relevant aspects of EU Food Law, ISO certification, and any specific national legislation of EU Member States with regard to their composition, manufacture, and control (
In the recent years an excessive use of food supplements as prevention and prophylaxis in different chronic diseases is observed. In order to increase the control on the placement on the market, utilization, and safety of food supplements, the European Commission took serious regulatory steps to harmonize the criteria for FS and to ensure that they are not provided with misleading information. A harmonized list of vitamins and minerals that may be added for nutritional purposed in FS and their doses was introduced with Directive 2002/46/EC and Directive 2006/37/EC/. Regulation (EC) No 1924/2006 established the rules for clear, accurate, and scientific evidence-based health claims of FS (EC 2006).
However, excessive use, uncontrolled consumption, or exposure to higher than recommended intakes and even interaction with specific medicines can cause toxicity risk and pose serious health concerns (
Аs the most accessible health care professionals, pharmacists routinely encounter patients seeking advice on various food supplements in their daily practice (
Studies also show that pharmacists would like to receive more detailed information on the quality of food supplements, interactions with medicines, and adverse effects related to their intake. Pharmacists also need more training and knowledge related to food supplements, especially regarding more specific pharmaceutical information, but a national policy in this area needs to be developed not only on a national but on a regional level, as well (
This prompted our interest to examine the pharmacists‘ attitudes working in community pharmacies in Bulgaria to dispensing and controlling food supplements to chronically ill patients.
A national anonymous survey was conducted using the direct questionnaire method among master pharmacists and assistant pharmacists working in community pharmacies in Bulgaria to assess their attitudes towards the dispensing and monitoring of food supplements in patients with chronic diseases. The questionnaire was prepared by the PhD student under the supervision and review of Maria Dimitrova. Pharmacists from 13 major cities were surveyed between June 2020 and June 2021. The point was to collect different answers from different parts of the country in order to analyze the behavior of the pharmacists in the community pharmacies in Bulgaria. In the beginning, the questionnaire was directly provided by the PhD candidate to the working pharmacists (in the pharmacies) and later on when the COVID-19 pandemic was seriously on-going the questionnaire was provided online via google forms. The asked pharmacists and assistant pharmacists were selected from chain pharmacies and small pharmacies in order to have a full overview. The questionnaire consisted of 8closed-ended and 2 opened-ended questions and aimed to collect data on the demographic characteristics of pharmacists (age, sex, location of workplace), as well as their attitudes regarding the role they might have and the knowledge they need to advise patients on food supplements, the risks associated with their use and the reporting of adverse effects by patients.
Data was proceeded through descriptive statistics on XLSTAT and Chi-Square test and cross tables for correlation.
The duration of the survey is 12 months (from June 2020 to June 2021). The survey included 151 pharmacists (135 Master pharmacists and 16 Assistant pharmacists) from 13 regional cities in the country (Sofia, Plovdiv, Pazardzhik, Blagoevgrad, Yambol, Haskovo, Veliko Tarnovo, Ruse, Stara Zagora, Pleven, Kyustendil, Varna and Burgas).
The demographic data of the surveyed healthcare professionals are summarized in the following table:
128 of 151 (84%) of the pharmacists surveyed were willing to recommend food supplements. 113 (88%) of these were master pharmacists. 81% of men and 86% of women respectively recommend the use of food supplements. The majority of the pharmacists (89%) respond that pharmacists could participate in the supervision chronically ill patients and food supplements intake - Table

Input data | Value (n/%) |
---|---|
As a Master Pharmacist/Assistant Pharmacist, would you recommend the usage of food supplements? | |
Yes | 128 (84%) |
No | 23 (16%) |
Do you inform patients about possible side effects of taking food supplements, especially in combination with medicines? | |

Approximately 1/5 of the professionals surveyed did not express an opinion on the benefit of including a pharmacist in the monitoring process. This may be due to the fact that they do not realize what their role actually is as an active part in the relationship with patients. Another point of view may be the insufficient awareness of the benefits of the proposed food supplements and the possible adverse interactions that may occur in chronically ill patients using both OTC products and medicines from different groups.
The smallest percentage of respondents reported that they would not recommend food supplements to patients and would not participate in counseling. These professionals believe that nutritional supplements are used as a means to increase turnover and have no real therapeutic effect.
Most of the master pharmacists and assistant pharmacists were of the opinion that their role in the monitoring process could be significant and refers to:
It is clear from the survey that the majority of professionals who expressed an opinion are competent and able to counsel patients and prescribe supplements.
For the inclusion of a pharmacist as an active part in chronic disease management, the data show that 84% of men would support it, with a higher percentage for women at 90%. By testing for a correlation between gender and agreement to include a pharmacist with Chi-squared test, the existence of a possible correlation was rejected. Indicated in the figure below.

All the results calculated with Chi-squared test could not generalize conclusions due to the small group of testing, but are sufficient to express a tendency of the analyzed amount of pharmacist. Тhe age of pharmacists did not influence the awareness of adverse events and the provided information to the patients. It is striking that the oldest pharmacists and assistant pharmacists are less likely to provide information to their patients about adverse events, but this statement cannot be supported by a statistical test of dependence due to the small number of pharmacists in this age group available in the data.
The attitudes towards recommending food supplements showed the largest difference between the youngest age group (18–24 years) and the oldest pharmacists (over 65 years), 90% and 75% would recommend FS respectively. With other words, 90% of the youngest age and 75% of the oldest pharmacists would recommend the usage of FS. The difference cannot be generalized due to the small number of pharmacists in the latter age group.
The oldest of the pharmacists surveyed categorically refused to participate in chronic disease management, which can be related to the fact that currently the pharmaceutical care in Bulgaria is not paid On the other hand, pharmacists in the second age group (25–44 years) were the most willing to supervise the intake of food supplements.
Patients would prefer to be consulted by their pharmacist forFS in 93% of cases. While those who do not want to be consulted by their pharmacist are 84%. Pharmacists inform the patients for adverse events in 46% of those who inquired about OTC and/or food supplements and 32% of those who did not inquire, respectively. In both cases, the difference in the percentages could not be confirmed by a statistical test for dependence on the variables.
In recent years an excessive use of food supplements for prevention, prophylaxis, and treatment of different chronic diseases is observed. In order to increase the control on the placement on the market, utilization, and safety of food supplements, the European Commission took serious regulatory steps to harmonize the criteria for food supplements and to ensure that they are not provided with misleading information. A harmonized list of vitamins and minerals that may be added for nutritional purposes in food supplements and their doses was introduced with Directive 2002/46/EC and Directive 2006/37/EC/. Regulation (EC) No 1924/2006 established the rules for clear, accurate, and scientific evidence-based health claims of food supplements (
Recent analyses of the Bulgarian pharmaceutical market show an increasing trend in the number of food supplements available on the pharmaceutical market in Bulgaria which almost reach the market of the over-the-counter medicines (
Our results are in line with other published articles. Pharmacists need more training and knowledge related to food supplements, as well as patients which are unable to distinguish OTC medication and food supplements. A national policy in this area needs to be developed on national and regional level. (
In 2021 Bukic et al. performed a cross-sectional study in Croatia to explore the community pharmacists` perception and knowledge on dietary supplements. The results showed that they needed further education about the practice of evidence-based pharmacy, especially on safety.
Similar studies have been performed in multiple countries worldwide – Australia, Ethiopia, Germany, Malaysia, New Zealand, Saudi Arabia, United Arab Emirates, and the USA, focusing on the need to identify different barriers to pharmacists to adapt their professional responsibilities in terms of supporting the appropriate and safe use of food supplements. Most of the researchers find a substantial gap between public awareness of the safe and effective use of food supplements and the role of the pharmacists as trusted consulters. They also call for more detailed implementation of the professional competencies of pharmacists as accessible health care professionals but also find the need to encourage further specialization on the effective and safe use of food supplements (
Rigorous monitoring and risk assessment of food supplements-drug interactions in patients with chronic diseases is needed, as well as prior implementation of additional education and training and pharmaceutical care in the community pharmacies. The pharmacists, as the most accessible health care professionals, are willing to participate and be implemented in the pharmaceutical care related to the food supplements intake. In combination with different medications, food supplements can cause many side effects, which can be prevented with a carefully provided consultation.
It would also be advisable to introduce a tightened mechanism of registration and regulation of food supplements in Bulgaria in order to minimize drug interactions and adverse events in their future use.
