Optimize your vitality with Fer Forte

Fer Forte is a dietary supplement designed to meet the iron needs of individuals with specific diets or requirements, such as pregnant women, vegetarians, or vegans. This product utilizes a bioavailable iron salt, iron bisglycinate, known for its excellent absorption and superior digestive tolerance.[1] Enriched with vitamins B6 and B9 in their bioactive forms, Fer Forte offers an effective synergy to support overall health.

Fer Forte is formulated to provide an optimized source of iron, an essential element for the proper functioning of many biological processes. Iron is vital as it promotes the formation of hemoglobin, the protein in red blood cells that transports oxygen from the lungs to all parts of the body.[2] This transport function is important not only for maintaining our energy levels and vitality but also for supporting the proper functioning of the immune system.

The body requires iron for several essential functions. It may not produce enough healthy red blood cells, and without an adequate amount of iron, this can lead to chronic fatigue, weakness, and a weakened immune system.

Maximize iron absorption with Fer Forte

  • One of the main advantages of Fer Forte is the use of iron bisglycinate, a form of chelated iron that offers superior bioavailability. This technical specificity means that the iron is bound to two glycine amino acid molecules, facilitating its absorption in the intestines. This configuration prevents the iron from reacting with other compounds in the stomach, which can often lead to gastrointestinal problems such as irritations and constipation, commonly observed with other forms of iron such as ferrous sulfate.[4] Thus, Fer Forte ensures a more effective absorption of iron by the body, maximizing the health benefits without the digestive discomfort associated with other supplements.
  • The chelated structure of iron bisglycinate also promotes better cellular absorption. By being more directly available for absorption, iron can be more efficiently utilized by cells for critical biological processes such as hemoglobin formation. This increased efficiency helps prevent iron deficiencies and reduce fatigue while supporting a healthy metabolism.
  • In our commitment to providing pure and natural products, Fer Forte incorporates natural excipients such as rice starch and capsules made of pullulan. Rice starch serves as a natural and inert filler, increasing the stability of the capsule without interfering with the effectiveness of iron bisglycinate. Pullulan, used for the capsules, is a natural polysaccharide obtained through fermentation. This choice of excipients not only ensures the purity of our formula but also contributes to the biodegradability and environmental safety of the product

Strengthen your health with iron bisglycinate and Quatrefolic®

Fer Forte is enriched with Quatrefolic®, an advanced and patented form of vitamin B9 (folates). This version of vitamin B9 is structured for direct assimilation by the body without requiring conversion by the enzyme MTHFR. Indeed, as genetic variations of this enzyme affect over 40% of the world's population, it can hinder the conversion of folic acid into a usable form by the body.[3] Thus, Quatrefolic® ensures efficacy regardless of the user's genetic profile.

  • Immune system reinforcement: Iron, vitamin B6, and Quatrefolic® play a role in supporting the body's defense mechanisms. A good reserve of these micronutrients is essential for maintaining proper immune system function.
  • Reduction of fatigue: Fatigue is often a sign of deficiency in iron and B vitamins. Fer Forte addresses this issue by providing micronutrients that contribute to reducing fatigue and regenerating bodily energy.
  • Support of nerve function: Vitamin B6, in particular, is essential for the normal functioning of the nervous system. It helps regulate mood and preserve neural health.
  • Formation of red blood cells and hemoglobin: Adequate intake of iron and folate is essential for the formation of red blood cells and hemoglobin, thus allowing for better oxygenation of the entire body.

FAQ: Everything you need to know about Fer Forte

Why choose Fer Forte over other iron supplements?

Fer Forte stands out for its use of iron bisglycinate, a highly bioavailable and well-tolerated form of chelated iron, minimizing common gastrointestinal side effects with non-chelated forms. Our formula includes the coenzymes of vitamins B6 and B9 (Quatrefolic®), optimizing the absorption and effectiveness of iron while providing additional health benefits such as immune support and fatigue reduction.

What are the benefits of the patented ingredient Quatrefolic® in Fer Forte?

Quatrefolic® is an advanced form of folate (vitamin B9) that does not require conversion by the enzyme MTHFR to be used by the body, ensuring immediate availability even for those with genetic mutations affecting this enzyme. This allows for better management of folate levels, which are essential for hemoglobin formation and normal nervous system function.

Is Fer Forte suitable for special diets?

Yes, Fer Forte is ideal for people following vegetarian or vegan diets, as it helps to fill the nutritional gap in iron intake. Additionally, the capsules are made from pullulan, a plant-based source, which is suitable for those avoiding animal products.

How does Fer Forte help reduce fatigue?

Fatigue is often linked to an iron deficiency, as iron is essential for the formation of hemoglobin, which transports oxygen in the blood. By providing highly absorbable iron bisglycinate, Fer Forte helps improve oxygen levels in the blood, revitalizing the body and reducing the sensation of fatigue. However, it is essential to emphasize the importance of diagnosing an iron deficiency before starting any iron-containing supplement. Fatigue can be caused by many factors, and self-supplementation without prior diagnosis can be not only ineffective but also potentially risky. Iron overload can lead to adverse effects.

Are there specific recommendations for taking Fer Forte?

Fer Forte should be taken according to the directions, one capsule per day with a glass of water during a meal. It is specifically recommended for adults, and pregnant women should consult a healthcare professional before using it to ensure it meets their specific iron needs during pregnancy.

Fer Forte: Your solution for better iron health

With its sophisticated formulation and the use of high-quality ingredients such as iron bisglycinate and Quatrefolic®, Fer Forte is the perfect solution for those looking to optimize their iron intake effectively and safely. Ideal for a properly functioning immune system, reducing fatigue, and improving overall health, Fer Forte represents a wise choice to maintain your well-being.
