The price of “health”: Herbalife ® and Juice Plus+ ® products under study

: The popularity of dietary supplements is increasingly on the rise: people are turning to them both for the purpose of weight loss and to maintain good health, so that in recent months and with the influence of the Covid-19 lockdown, dietary supplement companies have multiplied their profits, with Herbalife ®️ and Juice Plus+ ®️ among the biggest benefited, yet in both cases seems to be that the traders do not have the necessary knowledge on nutrition. The aim of this review is therefore to analyse the best-selling products of these companies in terms of their components and the available scientific evidence. The articles reviewed were obtained by a search through various databases, with specific selection criteria for each component and its supposed health benefits, giving preference to the most recent publications. Results show that some of these supplements’ ingredients do have scientific evidence supporting them (as is the case of coffee, green tea and , to a lesser extent, Aloe Vera), but others lack of significant evidence to attribute their claimed benefits (as is the case of substitute shakes, vitamin and omega supplements and glucomannan); moreover, adverse effects related to the consumption of these products have been reported and, in some cases, these had led to serious health consequences. In conclusion, it can be stated that the consumption of Herbalife ®️ and Juice Plus+ ®️ supplements do not provide benefits in terms of health, and effective measures and policies are needed to promote healthy lifestyles as the main important measure to adopt by the whole population.
