FAQs
What is the difference between fermented birch sap and fresh birch sap?
Does fermentation destroy nutrients?
Does fermented sap still contain alcohol?
No. Lactic fermentation is not alcoholic fermentation. It produces lactic acid — the same as that present in our intestines — but no trace of ethanol. It is a living drink, but without alcohol and without added sugar.
What is the difference between the classic version and the one with propolis?
What scientific evidence of its effectiveness?
Studies on lacto-fermentation show that it promotes the balance of the intestinal microbiota and the production of active probiotics (Lactobacillus, Leuconostoc). These microorganisms directly support immunity, digestion, and liver detoxification. Our sap, analyzed by the Strasbourg Research Center, has demonstrated a stable content of live lactic ferments, a guarantee of a real physiological benefit.
Can it be consumed all year round?
Yes. Traditionally consumed in spring, our fermented version can be used throughout the year, especially during seasonal changes, or after periods of fatigue, stress, or unbalanced diet.
Can everyone drink it?
Yes, except in case of specific medical contraindication (severe kidney failure, strict potassium-free diet). It is suitable for most adults and adolescents. In case of doubt, seek advice from a healthcare professional, especially for pregnant or breastfeeding women.
Why a slightly tangy or sparkling taste?
It is a sign that the sap is alive and active. The bubbles come from natural fermentation and gases produced by lactic ferments. No added gas or preservative — it is an indicator of vitality, not a defect.
How much should one drink?
A 3-week treatment, taking 15 cl per day on an empty stomach, is ideal to feel the effects. Two 1.5 L bags make up a complete treatment. The treatment can be repeated two to three times a year, depending on the body's needs.
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.
