Biosan for Supporting the Gut Flora

Our Heilnatura Pro-Biosan is a highly effective dietary supplement in convenient capsule form, specifically designed to support gut health. The combination of carefully selected lactobacilli, additional probiotic bacteria, and valuable micronutrients helps stabilize the intestinal flora and supports the body’s energy and metabolic processes. Complemented by psyllium husk powder and black cumin extract, Biosan can help reduce inflammation, strengthen the immune system, and sustainably promote intestinal function.

Effects of Biosan

Our Pro-Biosan Complex supports gut health on an individual level by addressing the specific needs of your digestive system. A balanced gut flora and proper digestion are essential for vitality, energy, and overall well-being. Products like Pro-Biosan combine lactic acid–producing bacterial cultures with dietary fibers such as psyllium husks and black cumin extract to support the gut on multiple levels—from bacterial balance to natural intestinal movement. Below are some of the benefits of the ingredients:

Regulation of Digestion

Psyllium husks are swelling dietary fibers that bind water and increase stool volume, gently stimulating natural bowel activity. This can be helpful for both constipation and irregular bowel movements. They also have a prebiotic effect, serving as food for beneficial gut bacteria and promoting a healthy microbial environment. The black cumin extract further supports digestion, soothes mucous membranes, and can help relieve bloating or cramps.

Support of the Gut Flora

The quantity of bacteria included and the carefully selected lactic acid–producing cultures contribute to stabilizing the gut flora through their specific properties.

Contribution to Energy Production and Nutrient Absorption

A healthy gut improves nutrient absorption. Since certain probiotic strains produce digestive enzymes, they facilitate the breakdown of food components. This can help reduce tiredness and fatigue, as the body is able to convert nutrients into energy more efficiently.

Protective Support During Stressors Such as Antibiotics

During or after antibiotic therapy, the gut flora can become imbalanced. Probiotics support the recolonization of the gut with beneficial bacteria, while psyllium husks provide a mild, balancing effect on digestion. Black cumin extract additionally helps soothe the gastrointestinal tract.

Support of the Immune System

A large part of the immune system is located in the gut. Probiotics can help improve the balance of intestinal bacteria and thereby strengthen immune function.

Overall, the combination of probiotic strains and prebiotic fibers creates a favorable environment for bacterial diversity and stable digestive function. This synergy enhances the positive effects on gut health and energy balance.

Biosan

Auf Grund einer aktuellen Erkrankung muss ich leider oft Antibiotika nehmen und es waren mehrmalige Krankenhausaufenthalte nötig. Ich hatte in der Vergangenheit oft Probleme mit meiner Verdauung und konnte nur durch regelmäßige und spezielle Essgewohnheiten das ausgleichen. Seit ich Biosan nehme, habe ich diesbezüglich keine Beschwerden mehr. Die Belastung durch das Antibiotikum und die Unterbrechung meiner speziellen Essgewohnheiten durch die Krankenhausaufenhalte, haben mich durch die Unterstützung von Biosan alles gut "verdauen" lassen. Ich werde auf jeden Fall Biosan weiterhin einnehmen.

Zu empfehlen

Sehr gut verträglich trotz Histaminintoleranz, wirkt auf meinen Darm ausgleichend und beruhigend. Ich werde das Produkt wieder kaufen. Nicht so gut ist, dass in der Produktbeschreibung hier im Shop nicht die enthaltenen Bakterienstämme aufgeführt sind. Sonst wäre es perfekt. Auf der Packung stehen sie dann aber drauf.

Bewertung von Jasminka M.

Ich habe es für meine ältere Tochter gekauft, weil sie immer schlimmere Entzündungen um den Mund herum bekam. Die Ärzte wollten ihr innerlich 6 Wochen Antibiotika verschreiben. Ich entschied mich dagegen und begann mit Biosan. Nach 2 Wochen wurden die Entzündungen weniger und jetzt nach 4 Wochen hat sie keine Entzündungen mehr, nur noch die Flecken aber auch diese werden weniger. Meine Tochter ist so glücklich, ausserdem nahm sie seit Beginn 4 kg ab. Ein positiver Nebeneffekt. Sie hatte einfach kein Hunger und es war ihr zu Beginn oft flau im Magen. Ich halte das für ein gutes Zeichen, denn es zeigt mir, dass sie entgiftet. Wir werden das Produkt weiterhin einnehmen, so ca 6 Monate. Bin gespannt was sich sinst noch zum positiven verändert. Meine jüngeren Tochter hat nun auch mit Niosan begonnen, da sie auch Hautunreinheiten plagen. Abgesehen davin, haben beide schon Antibiotika eingenommen, so daß ich mir erhoffe, die Darm flora mit den guten Bakterien wieder anzusiedeln. Ich kann das Produkt sehr empfehlen.

Nach einer Woche deutliche Besserung

Ich hatte grosse Probleme mit flüssigem und blutigem Stuhl. Dazu kommen juckende Hämorrhoiden. Nach einer Woche Pro-Biosan und Heidelbeerektrakt gingen die Symptome weg. Auch der Bauch rumorte nicht mehr. Dazu gehört aber auch eine Reduzierung des Alkoholkonsums.

Milk thistle extract capsules

Content: 90 Capsules (€0.27* / 1 Capsules)

From €24.00* (previously €27.90*)
Our premium milk-thistle capsules contain a standardized extract from the seeds of milk thistle (Silybum marianum), a time-honored member of the Asteraceae family. With its purple thistle-like blossoms and white-marbled leaves, the plant has been prized for centuries and is now considered the world’s most researched liver herb. Each capsule delivers a consistent 80 % silymarin content for reliable potency. The seeds naturally supply silymarin, a complex of bioactive flavonoids (silybin, silychristin, silydianin) with strong antioxidant properties. Milk-thistle liver formulas have been valued for hundreds of years and are now the focus of intensive research. Effect Heilnatura milk-thistle capsules provide carefully extracted silymarin. Discover what this remarkable plant extract can do: May support treatment of liver conditions such as cirrhosis by acting as an adjunct. Could help lower cholesterol levels. The silymarin extract reaches peak plasma levels 1.5 hours after ingestion. Studies show significant improvements in key liver markers: ALT and AST can drop markedly. May reduce fat accumulation in the liver (hepatic steatosis). Helps stabilize liver-cell membranes and may shield them from harmful substances. Silymarin can boost protein synthesis and activate DNA-repair pathways, promoting healthy cell regeneration and the removal of toxins. Dosage Suggested use Take two milk-thistle capsules daily. Ideally at the same times each day, e.g., morning and evening. For best results, do not skip doses and keep your routine consistent. Food supplement Do not exceed the recommended daily intake. Supplements are no substitute for a balanced, varied diet. Keep out of reach of children. Storage Store below room temperature. Refrigerate after opening.

Tip
Lactose tolerance

From €30.00*
Heilnatura Lactose toleranceContains lactase which is an enzyme responsible for the digestion of milk sugar (lactose). Some people have a deficiency of this enzyme, which can lead to lactose intolerance. Taking lactase supplements can offer various benefits in such cases. The combination of lactase, lactobacteria powder with guar gum and fibrulose can provide several benefits for digestion and gut health: Lactase: Digestion of lactose: Lactase is an enzyme that supports the breakdown of milk sugar (lactose). Taking lactase supplements enables people with lactose intolerance to digest dairy products better and reduce digestive problems. Lactobacteria powder: Promotion of the intestinal flora: Lactobacteria are probiotic bacteria that can support intestinal health. They help maintain a balanced gut flora and can improve immune function. Digestive support: Lactobacteria can help to promote digestion by improving the absorption of nutrients and stimulating the production of short-chain fatty acids. Guar gum: Source of fibre: Guar gum is rich in fibre, which can promote intestinal health. Fibre supports healthy digestion by regulating bowel movements and promoting the formation of benign bacteria in the gut. Blood sugar control: Fibre can help to stabilise blood sugar levels, which can be particularly beneficial for people with diabetes. Fibrulose: Prebiotic effect: Fibrulose is a prebiotic fibre that serves as food for probiotic bacteria in the intestine. By promoting the growth of these bacteria, fibrulose contributes to the maintenance of healthy intestinal flora. The combined intake of these components can have synergistic effects and support various aspects of digestion and gut health. Consumption recommendation:  Take 2 capsules daily before meals with plenty of liquid.Contents:  60 Capsules Ingredients per capsule:  Ingredients                              Share (2capsules)Lactase                                    100mgLactobacteria powder             200mgGuar gum                                 500mgFibrulose                                  100mg
