Main Highlights

OUR IRON COMPLEX TABLETS - Contain 18mg of iron, which is a crucial mineral that plays an essential role in the human body, including carrying oxygen to our organs and tissues. Our Iron supplements also include Vitamin B12 and Vitamin C, which work together to enhance the absorption and effectiveness of iron in the body. B12 supports the formation of red blood cells and helps maintain a healthy nervous system, while VC aids in the absorption of iron and promotes a healthy immune system.
OUR ADVANCED IRON COMPLEX - With vitamin B12 and VC is an effective and well-tolerated form of iron supplements that is used for iron deficiency anaemia and overall health. Our unique formula with vitamin B12 and VC helps improves iron absorption, and enhances the production of red blood cells. Iron supplements for men and women are generally similar, as both genders require iron for optimal health. However, women may need more iron than men due to menstruation and pregnancy.
REDUCTION OF TIREDNESS & FATIGUE - Iron is needed for the production of adenosine triphosphate (ATP), which is the body's primary source of energy. Without enough iron, the body cannot produce enough ATP, which can lead to feelings of fatigue and weakness. Iron also plays a role in the metabolism of neurotransmitters such as dopamine and serotonin (mood regulation). Low levels of iron can lead to a decrease in these neurotransmitters, which can contribute to feelings of fatigue and low mood.
SAFETY & QUALITY - To uphold the highest standards of safety and quality, our products undergo post-production testing for heavy metals and other unwanted compounds, ensuring full compliance with international regulations. Once testing is complete, products are bottled and packaged in BRC Grade AA certified facilities, guaranteeing that our rigorous quality standards are reliably maintained and delivered to you.
