GlobalBurden of impaired vitality in the general population and potential nutritional solution
The National Health and Wellness Survey (NHWS) database (April–July 2018) was analysed to better understand the profile of healthy Europeans with impaired vitality level and its impact on their QoL [4]. A total of 24,295 adults in good health, aged between 18 and 64 years, were assigned to one of the four vitality groups based on statistical distribution of their vitality score (12-Item Short Form Survey [SF-12] questionnaire): <40: lowest vitality (n = 4,173), 40 to <50 (n = 9,327), 50 to <60 (n = 9,059) and ≥60: highest vitality (n =1,736) [4].
Low vitality level had a high impact on QoL deterioration and was associated with a high economic burden in the general population. The lowest vitality group (<40) was related to an increased odds ratio (OR; 95% confidence interval [CI]) of reporting any problem regarding anxiety/depression (10.3; 8.7–12.3), pain/discomfort (5.6; 4.8–6.5) and usual activities (5.3; 4.2–6.6) evaluated by the EuroQoL 5-Dimension 5-Level (EQ-5D-5L) questionnaire compared to the highest vitality group (>60) (Fig. 1). Also, the low vitality group was related to an increased OR for impairment of presenteeism and activity compared to the highest vitality group (>60).

With an OR of 2.6 (95% CI: 2.3–2.9), patient activation measurement (PAM) level 1 (lack of knowledge and confidence for managing their own health) was the characteristic most associated with vitality impairment. This suggests that for this population, higher engagement in self-care might considerably reduce the daily life burden of low vitality, and opens new roads for innovative health strategies, including accessible solutions, helping to modify people’s behaviour.
Open-label study on Panax ginseng G115®
Interestingly, previous open-label studies have shown the benefits of vitamins, minerals and natural ingredients on mental and physical well-being [5, 6]. The root of Panax ginseng C.A. Meyer (Asian ginseng) has been used for centuries in traditional Asian medicines for a wide variety of ailments, including fatigue. A specific extract, G115®, standardized to 4% of ginsenosides, has notably shown its efficacy in several clinical studies [7–12]. In individuals (n = 103) experiencing fatigue and/or lack of vitality for at least two weeks, a 3-month supplementation with Panax ginseng G115®, vitamins, minerals and natural ingredients improved mental and physical fatigue, starting from two weeks of intake and throughout the study period, as compared to baseline [5]. Comparisons between baseline and 90-day Multidimensional Fatigue Inventory (MFI) were performed using a mixed model for repeated measurements with time points (baseline, D1, D15, D30, D60, D90) as categorical and subject as a random effect. The levels of reduced activity and motivation improved starting from week 2 (reduced activity: –2.29 units; 95% CI: –3.18 to –1.40; p < 0.0001; reduced motivation: –2.82 units; 95% CI: –3.58 to –2.05; p < 0.0001) compared to baseline (mean ± SD, 14.1 ± 4.16; 13.5 ± 3.36, respectively) (Fig. 2).
