Iron supplements come in different forms, and choosing the right one can make a significan difference in comfort, absorption and overall compliance.
Ferrous sulphate has been widely used for many years and is effective in treating iron
deficiency when recommended by a healthcare professional. However, it may cause
digestive side effects such as constipation, nausea or stomach discomfort in some
individuals, which can make it difficult for some people to continue long-term use.
Ferrous bisglycinate is an iron amino acid chelate in which iron is bound to the amino acid
glycine. This form is recognised for its high absorption potential and improved
gastrointestinal tolerance, making it a popular choice for those who experience sensitivity
with traditional iron supplements.
Comparison at a glance:
- Ferrous Sulphate: Widely used, effective, but may cause digestive discomfort in some individuals.
- Ferrous Bisglycinate: High absorption potential, generally gentler on the stomach, and suitable for long-term nutritional support when appropriate.
At Clean Health Formula, we prioritise advanced nutrient forms that are designed to support both effectiveness and digestive comfort, helping individuals maintain consistency with their supplementation routine.
Always use iron supplements under the guidance of a healthcare professional and based on laboratory assessment.
Takeaway: Ferrous bisglycinate offers an advanced option for individuals seeking an iron
supplement with excellent absorption potential and improved stomach comfort.
