  • Supporting Maternal Cognitive Function: Vitamin B12 contributes to the normal functioning of the nervous system, supporting concentration and memory during a period of increased demands and sleep deprivation.

Scientific Formula & Ingredients

Ferrochel®

Liposomal Ferrochel® (Iron)

The Key Difference: We use Ferrochel®, a chelated form of iron (ferrous bisglycinate) where the mineral is bound to amino acids. Unlike standard iron salts (sulfates), this organic form inherently has a higher absorption rate and does not irritate the gastrointestinal mucosa.

Liposomal Protection: In our formula, Ferrochel® receives dual protection. The chelated form protects the iron molecule, and the liposome protects the chelate structure itself. This ensures the iron passes through the harsh environment of the stomach unchanged and arrives at the intestine for maximum absorption.

Quali-C®

Liposomal Quali-C® (Vitamin C)

The Key Difference: Quali-C® is the benchmark for purity and quality in Vitamin C (ascorbic acid), produced in Europe. Using this standard guarantees the absence of impurities and the highest stability of the source ingredient.

Liposomal Protection: Vitamin C is an unstable molecule that degrades easily. We place Quali-C® in liposomes to shield it from oxidation in the digestive tract. The liposomal shell allows for the delivery of Vitamin C directly to the cells, providing significantly higher bioavailability compared to conventional tablets or powders.

MecobalActive®

Liposomal MecobalActive® (Vitamin B12)

The Key Difference: Instead of common cyanocobalamin, we use MecobalActive®—pure methylcobalamin. This is the biologically active form of B12, which requires no additional conversion by the body. The body receives the nutrient in a ready-to-use state.

Liposomal Protection: Liposomal encapsulation ensures that this ready-to-use form of B12 is protected throughout its journey in the GI tract and is efficiently transported into the bloodstream, bypassing potential absorption issues in the stomach.

Quatrefolic®

Liposomal Quatrefolic® (Folate)

The Key Difference: Quatrefolic® is a 4th-generation folate that solves the absorption problem of conventional folic acid. It is a ready, active folate (5-MTHF) that does not require conversion by the MTHFR enzyme, which is critical for individuals with common genetic variations of this enzyme.

Liposomal Protection: Our liposomal technology provides gentle and maximally effective delivery of this advanced folate form through the intestinal wall. This ensures that the most innovative folate on the market is fully absorbed.

RTRPRQ™ Multi-Phase Liposomal Delivery Platform

Nutrient-Specific Encapsulation

We understand that every nutrient is unique. Our platform uses a sophisticated process where the size, composition, and electrical charge of each liposome are precisely tailored to the specific ingredient it carries. A liposome for iron is engineered differently than one for Vitamin C. This customized approach ensures that each nutrient is perfectly protected and primed for its journey.

Targeted Gastrointestinal Release

RTRPRQ™ is a multi-phase system. We engineer our liposomes with specific release triggers, allowing them to bypass the harsh environment of the stomach and release their payload at the optimal site for absorption within the small intestine. This precision targeting prevents nutrient degradation and ensures it is delivered where the body can most effectively utilize it.

Superior Bioavailability and Tolerability

The result of this intelligent design is significantly enhanced bioavailability. By protecting the nutrients and releasing them in the right place, our platform ensures that more of the active ingredient reaches the bloodstream compared to conventional supplements. This efficient delivery also means the formula is exceptionally gentle on the system, eliminating the gastric discomfort often associated with high-potency ingredients.

Exceptional Stability

The integrity of our nutrients—from the moment of manufacture to the moment of absorption—is paramount. The RTRPRQ™ platform provides a robust shield, protecting the active ingredients from degradation by oxygen, moisture, and temperature. This exceptional stability guarantees that the product remains potent and effective throughout its entire shelf-life
Spentus® Perinatal Intelligent Capsule

Precision Opening Point

Our intelligent capsule is made from pH-sensitive plant-based polymers. It is designed to remain fully intact in the acidic environment of the stomach, protecting the sensitive liposomes from degradation. The capsule opens only upon reaching the more alkaline environment of the small intestine—the ideal location for the release and subsequent absorption of the nutrients.

Dual Protection System

We employ a two-level approach to protecting the active ingredients. First Level: The intelligent capsule itself, which serves as a durable outer shield, protecting all contents from moisture, oxygen, and stomach acid. Second Level: The liposomes inside the capsule, which individually protect each nutrient molecule. This "protection for the protectors" system ensures unprecedented preservation and stability of the formula.

Custom Design

Every detail of the capsule—from its size, optimized for easy swallowing, to the choice of materials, which are fully compatible with our unique liposomal formula—has been designed specifically for Spentus® Perinatal. This is not a standard, off-the-shelf capsule, but a specially engineered component that is an integral part of our technology.

Pharmaceutical-Grade Labeling

For your safety and confidence, each capsule is clearly marked with non-toxic, pharmaceutical-grade ink. This professional labeling, similar to that used on prescription medications, allows for easy product identification, confirms its authenticity, and serves as a visual testament to our adherence to the highest manufacturing standards (GMP).
Spentus® Perinatal Pharmaceutical-Grade Packaging

  • Absolute Barrier Protection

    We use multi-layered, pharmaceutical-grade composite materials that create a virtually impenetrable barrier to the three main enemies of nutrient stability: moisture, oxygen, and UV light. This protection ensures that the sensitive liposomal complexes and active ingredients within the capsules maintain their original potency and are not subject to oxidation.

  • Individual Dose Protection

    Each intelligent capsule is placed in an individual, hermetically sealed cavity of a blister pack. Unlike a conventional bottle, which exposes all contents to air every time it's opened, our packaging protects each dose from environmental contact until the moment of use. This provides maximum hygiene, stability, and convenience, especially when traveling.

  • Compliance with Pharmaceutical Standards

    All packaging materials used for Spentus® Perinatal comply with the strict cGMP (current Good Manufacturing Practices) standards applied to the packaging of prescription pharmaceutical drugs. This means the materials are certified as non-toxic, do not react with the contents, and do not leach any foreign substances, guaranteeing the absolute purity and safety of the product.

  • Uncompromising Quality Over Cost-Cutting

    We have deliberately chosen advanced and more expensive packaging solutions, rejecting standard and cheaper alternatives like plastic bottles. Our philosophy is that cutting costs on packaging means compromising on the efficacy and safety of the final product. Your trust and health are our top priority, and we make no compromises in any aspect

Spentus® Perinatal Dosing Protocol

  • Flexible and Clinically-Driven Approach

    We understand that every woman's needs are unique and change over time. Our protocol is not a rigid "one-dose-for-all" instruction. It offers flexible, clinically-driven recommendations that can be adapted by your healthcare provider depending on the stage (planning, trimester of pregnancy, postpartum) and your individual lab results and needs.

  • Evidence-Based and Aligned with Global Standards

    The recommended dosages are based on the most current scientific data and align with the guidelines of leading global health organizations (including WHO, ACOG, EFSA) in the field of perinatal nutrition. This ensures that you receive nutrients in effective and safe amounts that are recognized at an international medical standard.

    This protocol was developed exclusively for Spentus® Perinatal by a team of experts in obstetrics and nutrition. It accounts for the uniquely high bioavailability of our liposomal ingredients, which distinguishes it from standard recommendations for conventional supplements. This is a tailored regimen created specifically for our high-tech formula.

  • Maximum Efficacy with Minimal Dosing

    Thanks to the superior absorption provided by our liposomal platform, our protocol allows for achieving the necessary therapeutic effect with smaller and gentler dosages. Our approach is "smart efficacy," not "brute force." This ensures better tolerability, reduces the burden on the body, and serves as proof of our formula's highest efficiency.
Frequently Asked Questions (FAQ)

  • What is the key advantage of Spentus® Perinatal compared to traditional iron supplements?

    The key advantage of Spentus® Perinatal is our unprecedented 4-level iron protection system, designed to ensure maximum absorption without side effects. It is the first system in the world where iron is so comprehensively protected all the way to its point of absorption.

    Here is how it works:

    Level 1: Chelation. We start with Ferrochel® iron, where the mineral is already initially protected by being strongly bound to amino acids. This in itself prevents direct contact of the iron with the stomach lining.

    Level 2: Liposomal Encapsulation. Next, we place this chelated iron into a liposome—a microscopic protective sphere that serves as the ideal "transport container" for the nutrient.

    Level 3: The Intelligent Capsule. All the liposomes are packed into our pH-sensitive capsule. It is engineered to pass through the stomach intact and dissolve only in the small intestine—the optimal location for absorption.

    Level 4: The Pharmaceutical Blister. Finally, each capsule is hermetically sealed in an individual blister cavity, which protects it from oxygen and moisture right up to the moment of use, guaranteeing full potency.

    In addition to this unique protection system, Spentus® Perinatal includes three essential synergistic nutrients in their most active forms—Vitamin C (Quali-C®), Folate (Quatrefolic®), and Vitamin B12 (MecobalActive®)—for complete support of the healthy red blood cell formation process.

  • Does Spentus® Perinatal cause GI side effects like other iron supplements?

    Spentus® Perinatal was specifically engineered for maximum tolerability. We use chelated Ferrochel® iron, which does not make direct contact with the stomach lining. Combined with our liposomal protection, this design helps to minimize the risk of side effects like nausea, constipation, or gastric discomfort often associated with conventional iron salts.

  • I have an MTHFR gene mutation. Is this product suitable for me?

    Yes, this product was designed with this in mind. Spentus® Perinatal contains folate in the form of Quatrefolic® (5-MTHF). This is the finished, biologically active form of folate that does not require conversion by the MTHFR enzyme. Therefore, your body can use it immediately, regardless of any genetic variations.

  • How and when is it best to take the capsules?

    You can take Spentus® Perinatal at any time that is convenient for you. Our liposomal technology ensures the effective absorption of nutrients independent of food intake, so you are not tied to breakfast, lunch, or dinner.

    However, for best results, we recommend taking the capsule at the same time each day (for example, every morning). This helps to maintain a stable concentration of nutrients in the bloodstream, ensuring a steady supply to your body throughout the day.

  • How long should I take Spentus® Perinatal?

    Spentus® Perinatal is designed to provide nutritional support throughout all four stages: planning, pregnancy, delivery, and postpartum.

    The need for key nutrients like iron, folate, vitamin B12, and vitamin C remains high throughout this entire period to support maternal health, fetal development, and postpartum recovery.

  • Can I take Spentus® Perinatal simultaneously with other supplements?

    Spentus® Perinatal contains 50 mg of highly bioavailable Ferrochel® iron in each capsule. To avoid the risk of overdose, it is crucial not to take it simultaneously with other iron-containing supplements. Always sum the dosages of key nutrients from all products you are taking.
