Frequently asked questions
- What is sucrosomial iron?
- Sucrosomial iron is an iron-encapsulation technology (a sucrester-based matrix surrounding the iron) marketed for improved tolerability and reduced GI side effects versus standard ferrous sulphate. Developed by Italian pharmaceutical company PharmaNutra.
- How does this compare to Active Iron?
- Both target the gut-tolerability issue that standard ferrous sulphate often causes. Active Iron uses a whey-protein-matrix iron formulation; SiderAL Forte uses sucrosomial encapsulation. Both carry banned-substance certs (Active Iron = Informed Sport, SiderAL = NSF Certified for Sport).
- Where can I buy it?
- Amazon UK at £25 is the listed retailer.
- Is it Informed Sport tested?
- It carries NSF Certified for Sport — equivalent banned-substance cert. Each batch is screened against 280+ banned substances.
- Should I take iron with food?
- Iron is best absorbed on an empty stomach, but is also better tolerated with food. Sucrosomial iron is positioned as more flexible — check the on-pack guidance for the brand's recommendation.
