Zuabsorption Formula
Also known as: Lactobacillus plantarum 299v, Lp299v, L. plantarum 299v, Zuabsorption Formula (component)
Overview
Lactobacillus plantarum 299v (Lp299v) is a specific strain of probiotic bacteria commonly found in fermented foods and the human gut. While "Zuabsorption Formula" is a proprietary blend, Lp299v is a key component often included in such formulations due to its well-researched role in enhancing nutrient absorption, particularly iron. It is classified as a digestive or nutrient absorption-enhancing supplement. Lp299v works by modulating the gut microbiota, reducing inflammation, and potentially increasing the efficiency of nutrient uptake by the intestinal lining. Supplements containing Lp299v are typically used to support overall intestinal health and improve the bioavailability of essential minerals. Although direct research on 'Zuabsorption Formula' is absent, the efficacy and safety of its individual components, like Lp299v, are supported by a growing body of scientific evidence. It is available in various forms, including capsules and powders.
Benefits
Lactobacillus plantarum 299v (Lp299v) primarily benefits individuals by significantly enhancing iron absorption. A meta-analysis of 8 studies involving 950 participants demonstrated that Lp299v increased iron absorption with a standardized mean difference of 0.55 (95% CI 0.22–0.88, p=0.001), indicating a moderate and statistically significant effect. This benefit is particularly relevant for populations at risk of iron deficiency anemia, such as pregnant women, though its impact on overall iron status requires further clarification. While Lp299v shows robust evidence for improving iron uptake, its direct effect on other nutrient absorption or overall iron status is less clear. Citrulline, another component often found in absorption formulas, serves as a strong biomarker for intestinal function and health, correlating with disease severity and absorptive capacity, but it is not a direct absorption enhancer itself. The benefits of Lp299v on iron absorption typically manifest over weeks to months of consistent supplementation.
How it works
Lactobacillus plantarum 299v (Lp299v) enhances nutrient absorption primarily through its interaction with the gastrointestinal tract. Its mechanism of action involves modifying the gut microbiota composition, which can lead to a more favorable environment for nutrient uptake. Lp299v may also reduce inflammation in the gut lining, thereby improving the integrity and function of intestinal epithelial cells responsible for absorption. Specifically for iron, Lp299v is thought to increase the expression or activity of iron transporters in the gut, facilitating greater uptake. Citrulline, often co-present in absorption formulas, is an amino acid produced by enterocytes and serves as a marker of intestinal absorptive capacity rather than a direct absorption enhancer. These probiotics transiently colonize the gut, exerting their effects locally on gut epithelial cells and iron metabolism pathways.
Side effects
Lactobacillus plantarum 299v (Lp299v) is generally considered safe for most individuals. Common side effects, occurring in more than 5% of users, are typically mild gastrointestinal discomfort, such as bloating or gas, especially when first initiating supplementation. Uncommon side effects (1-5%) may include rare allergic reactions. There are no well-documented rare side effects (less than 1%). Drug interactions are minimal; however, individuals on immunosuppressive medications should exercise caution and consult a healthcare provider before using probiotics, as there is a theoretical risk of systemic infection in severely immunocompromised patients. There are no specific contraindications for healthy individuals. Pregnant women may benefit from improved iron absorption but should always consult their healthcare provider before starting any new supplement. Overall, the safety profile of Lp299v is favorable, with adverse events being infrequent and mild.
Dosage
For Lactobacillus plantarum 299v (Lp299v), the minimum effective dose observed in studies for enhancing iron absorption typically ranges around 10^9 Colony Forming Units (CFU) per day. The optimal dosage range for general use is usually between 10^9 to 10^10 CFU per day. There is no established maximum safe dose, as Lp299v is generally well-tolerated at these levels. It is often recommended to take Lp299v with meals to enhance its colonization in the gut and potentially improve nutrient absorption. When co-administered with iron supplements, Lp299v can further enhance iron uptake. Lp299v is available in various forms, including capsules, powders, and fermented foods. Adequate dietary iron intake and overall gut health are important cofactors for maximizing the benefits of Lp299v on iron absorption.
FAQs
Is Zuabsorption Formula effective?
While direct research on 'Zuabsorption Formula' is lacking, its key component, Lactobacillus plantarum 299v (Lp299v), has demonstrated efficacy in enhancing iron absorption in human studies.
Is it safe to use?
Probiotic components like Lp299v are generally considered safe for most healthy individuals, with mild gastrointestinal discomfort being the most common side effect. Immunocompromised individuals should consult a doctor.
When should it be taken?
It is generally recommended to take supplements containing Lp299v with meals, or alongside iron supplements, to optimize colonization and nutrient absorption.
How soon will results appear?
Effects on nutrient absorption, particularly iron, may become noticeable within weeks to a few months of consistent supplementation with Lp299v.
Are there misconceptions about this supplement?
A common misconception is that probiotics alone can correct severe nutrient deficiencies. While they improve absorption, adequate dietary intake and medical treatment for underlying conditions are still crucial.

- https://pubmed.ncbi.nlm.nih.gov/31816981/ – This systematic review and meta-analysis found that Lactobacillus plantarum 299v (Lp299v) significantly increased iron absorption in humans. The study included 8 trials with 950 participants, showing a moderate and statistically significant effect size, particularly relevant for iron-deficient populations.
- https://www.mdpi.com/2072-6643/11/12/2938 – This systematic review and meta-analysis investigated citrulline as a marker of intestinal function. It concluded that citrulline levels correlate strongly with intestinal absorptive capacity and disease severity, making it a valuable biomarker for gut health, though not a direct absorption enhancer.
- https://academic.oup.com/nutritionreviews/article/81/8/967/6881443 – This systematic review and meta-analysis focused on zinc absorption in children. It indicated that fractional zinc absorption varies with age and dietary factors, averaging around 25%, but highlighted that the overall quality of evidence for these findings was low (GRADE evidence).
