Product features.
A good fit for Comparing an explicitly declared iron form and tablet amount when iron supplementation has been judged appropriate.
- Names ferrous bisglycinate Core Chelate as the iron source, allowing comparison with other iron forms.
- The manufacturer separates 14mg per tablet from its 28mg two-tablet serving, making the amount easier to check.
Iron is not a general energy supplement for everyone. The two-tablet serving exceeds the NHS amount normally advised without professional guidance.
Check the exact version, pack size and seller terms before buying.
The details that matter.
- Photographed pack
- 180 vegan tablets
- Iron source
- Ferrous bisglycinate Core Chelate
- Iron per tablet
- 14mg
- Manufacturer serving table
- 2 tablets provide 28mg iron; 90 servings
- Retailer directions
- 1 or 2 tablets with food; suitability and amount require individual review
- The NHS says 17mg or less supplemental iron daily is unlikely to cause harm, with higher amounts taken on GP advice. Review the 28mg serving before use.
- Keep iron supplements away from children: very high doses can be fatal. The word gentle does not remove overdose or digestive risks.
- Persistent tiredness needs its cause assessed. Compare your iron plan with a clinician rather than using a retailer energy claim as a diagnosis.
Cycling & duration.
Ingredient timeframes describe the cited preparation; they do not establish a cycle for every finished formula.
Iron bisglycinate
- On/off pattern
- Iron use follows an assessed need and response, not routine on/off weeks.
- Duration & evidence
- There is no standard OTC bisglycinate course. NHS guidance for prescribed ferrous sulfate describes several months of anaemia treatment, often continuing 3 to 6 months after improvement; that is not an instruction for this different product.
- When to review
- Agree whether iron is needed, the elemental amount and any blood-test follow-up with a clinician before starting or extending a course.
- This product declares 14mg per tablet and 28mg per two-tablet serving. A short cycle does not justify taking a higher amount without an indication.
- Do not interrupt prescribed anaemia treatment according to a supplement calendar, or use fatigue alone to diagnose iron deficiency.
