FAQs
What is the difference between sap fermented with propolis and classic fermented sap?
Does propolis change the taste?
Can everyone consume propolis sap?
Yes, except for people allergic to bee products (honey, wax, pollen, propolis). In this case, it is better to opt for the propolis-free version. For pregnant women, breastfeeding mothers, or children, seek advice from a healthcare professional before the treatment.
What is the scientific evidence of its effectiveness?
Research conducted on propolis and lacto-fermentation shows their beneficial effects on the intestinal microbiota, immunity, and resistance to respiratory infections. Propolis contains flavonoids and phenolic acids with strong antioxidant and antimicrobial power. Our sap, analyzed by the Strasbourg Research Center, contains live lactic ferments and active polyphenols, guarantors of its natural effectiveness.
Can it be consumed at the same time as a course of dietary supplements?
Yes, absolutely. The fermented sap acts on the terrain — that is, the microbiota and the elimination organs — without interacting with the supplements. It even improves their assimilation thanks to its probiotic and remineralizing action.
Does it contain alcohol because of fermentation?
No. Lacto-fermentation produces no alcohol: it only generates lactic acid, beneficial for intestinal flora. The sap is therefore alcohol-free, with no added sugar, and suitable for all diets.
How to preserve the sap with propolis?
Before opening: at room temperature, away from light. After opening: in the refrigerator, well sealed, to be consumed within 3 to 4 weeks. A slight deposit or a fine fizz may appear — this is normal and a sign of active fermentation.
Is it normal for the taste or color to change over time?
Yes. It is a living product: fermentation continues slowly, sometimes causing a change in hue or a more tangy taste. These variations are natural and do not affect the quality or the benefits of the product.
How much should be drunk for a complete treatment?
A complete treatment corresponds to 2 bags of 1.5 L, that is 3 weeks at a rate of 15 cl each morning on an empty stomach. It can be renewed at each change of season or during periods of fatigue or immune decline.
Why choose LIVLAB sap rather than another brand?
Because it is artisanal, French, and traceable: - hand-harvested in the forests of the Vosges, - naturally fermented, without pasteurization, - produced in small batches, in collaboration with a pioneering fermentation artisan (Jérémie) and the Strasbourg Research Center. The majority of industrial saps are micro-filtered, pasteurized, or diluted with water: ours remains raw, alive, and whole.
