MAGISNAT MEETING – July 4th, 2022

"Comments from a Food Science Expert on the New Dietary Supplement Garlive Recovery"

The topic was the quality of the hydroxytyrosol-based dietary supplement developed by MAGISNAT, Garlive Recovery.

We first discussed the WHO publications:





Q. Can micronutrient (vitamin and mineral) supplements prevent COVID-19 in healthy individuals or cure it in those with COVID-19 disease?

A. No. There is currently no guidance on micronutrient supplementation for the prevention of COVID-19 in healthy individuals or for the treatment of COVID-19. Micronutrients are critical for a well-functioning immune system and play a vital role in promoting health and nutritional well-being. Wherever possible, micronutrient intakes should come from a nutritionally balanced and diverse diet, including from fruits, vegetables and animal source foods.

Q. Are vitamin D supplements needed if individuals are not exposed to sunlight due to lockdowns?

A. Vitamin D can be made in the skin by exposure to sunlight or obtained through the diet from natural sources (e.g. fatty fishes such as salmon, tuna and mackerel, fish liver oils, beef liver, cheese and egg yolks), or from vitamin D-fortified foods or vitamin D-containing supplements.

In situations where individuals’ vitamin D status is already marginal or where foods rich in vitamin D (including vitamin D-fortified foods) are not consumed, and exposure to sunlight is limited, a vitamin D supplement in doses of the recommended nutrient intakes (200-600 IU, depending on age) or according to national guidelines may be considered.

We also asked Professor Tommaso Beccari (Department of Pharmaceutical Sciences, Food Science and Nutrition Section, University of Perugia, Italy) for his opinion on the product’s qualities and characteristics: he composed a press note answering that question, which has been disseminated in newspapers and blogs (links are listed below).

This work is to be considered important, because it seems that a very small number of people in the U.S. take olive polyphenols directly from foods (such as: fermented olives, olive paste, extra virgin olive oil, or olive polyphenol concentrates in the form of supplements).

*“None of the reported studies or the patent can be used to claim the properties of dietary supplements. Dietary supplements do not possess any therapeutic or preventive properties.”



The main focus of this meeting was to verify how many scientific papers hypothesize the important role played in particular by olive tree polyphenols in dietary supplementation.

  1. “Hydroxytyrosol: A natural compound with promising pharmacological activities”**
  2. “Impact of phenolic-rich olive leaf extract on blood pressure, plasma lipids and inflammatory markers: a randomized controlled trial”
  3. “Antioxidant activity of Hydroxytyrosol and Vitamin E reduces systemic inflammation in children with paediatric NAFLD”
  4. “Effect of Long-Term Hydroxytyrosol Administration on Body Weight, Fat Mass and Urine Metabolomics: A Randomized Double-Blind Prospective Human Study
  5. “Antioxidant Effects of a Hydroxytyrosol-Based Pharmaceutical Formulation on Body Composition, Metabolic State, and Gene Expression: A Randomized Double-Blinded, Placebo-Controlled Crossover Trial
  6. Secoiridoids delivered as olive leaf extract induce acute improvements in human vascular function and reduction of an inflammatory cytokine: a randomised, double-blind, placebo-controlled, cross-over trial”
  7. “The Effect of Olive Leaf Extract on Upper Respiratory Illness in High School Athletes: A Randomised Control Trial”
  8. “Olive Leaf Extracts Act as Modulators of the Human Immune Response
  9. Evidence that Vitamin D Supplementation Could Reduce Risk of Influenza and COVID-19 Infections and Deaths”
  10. “Western Dietary Pattern Antioxidant Intakes and Oxidative Stress: Importance During the SARS-CoV-2/COVID-19 Pandemic
  11. Link between Viral Infections, Immune System, Inflammation and Diet

*“None of the reported studies or the patent can be used to claim the properties of dietary supplements. Dietary supplements do not possess any therapeutic or preventive properties.”
