Livlab

No. The page claims it helps eliminate toxins from the liver and kidneys, but there is no evidence that any beverage improves organ detoxification in a healthy person — the liver and kidneys perform that function continuously on their own, and no clinical study is cited on the page. What is plausible is more modest: birch sap supplies potassium, magnesium, manganese and other minerals, and a live lacto-ferment may contribute to gut microbial diversity. Treat it as a mineral-rich seasonal drink rather than a cleanse.

Livlab states this itself, to its credit: anyone with severe kidney insufficiency or on a strict potassium-restricted diet should avoid it, because birch sap is naturally potassium-rich and impaired kidneys cannot clear excess potassium. Beyond the page's own warning, if you take potassium-sparing diuretics, ACE inhibitors or angiotensin-receptor blockers, discuss a 21-day daily course with your doctor first for the same reason.

This is not addressed on the page and it should be. Birch sap can carry birch pollen proteins, and birch-pollen allergy is one of the most common in northern Europe, with oral allergy syndrome cross-reactions to apple, carrot, celery and hazelnut. If you are allergic to birch pollen, ask your doctor or allergist before trying this product, and do not start with a full 15 cl dose.

The FAQ advises pregnant and breastfeeding women to consult a health professional, which is the right answer — it is an unpasteurised live product, and unpasteurised foods are generally approached with caution in pregnancy. The page describes it as suitable for most adults and adolescents but says nothing specific about young children, so ask before giving it to a child.

15 cl every morning on an empty stomach. A full course is two 1.5 L pouches over 21 days, which the FAQ says can be repeated two to three times a year. At €34.90 per pouch that is roughly €70 per 21-day course, or about €3.50 per daily dose — worth knowing before you order a single pouch expecting it to be enough.

The ingredients are described as organic and bottling takes place in a certified organic Alsatian workshop, but no AB or Ecocert logo, certifying body or certificate number is published. If certified organic status matters to you, request the certificate through the help centre before ordering.

The page does not say, which is a notable gap for an unpasteurised live product. Unpasteurised ferments normally need refrigeration and are consumed within a defined window after opening. Ask Livlab for the opened-pouch shelf life and storage temperature, and refrigerate it after opening as a default.

Express delivery is stated at 1–2 business days, but the free-shipping threshold appears on the page as an unfilled template placeholder, so the cost is only visible at checkout. No returns policy or guarantee is stated on the product page — only a link to the general terms of sale. Given this is a perishable, unpasteurised food product, returns may well be restricted, so check the terms before ordering.

Birch sap flows for a short window in early spring as the trees break dormancy, and this product is tied to that annual harvest in the Hautes Vosges. Seasonal availability is a point in its favour — it is consistent with genuine fresh sap rather than a year-round industrial concentrate.

Yes. Every Livlab code listed on smartstorereview is tested before publication and rechecked regularly. Because a full course needs two pouches, check whether a code applies to multi-pouch orders or bundles, and whether it brings you above the free-shipping threshold once that figure displays correctly at checkout.
