Red blood cell support, energy metabolism, iron absorption support
Adults with low dietary iron intake or those with busy, active lifestyles seeking daily energy-related nutritional support.
Take 1 capsule 1 to 3 times daily with meals; taking with food may improve tolerance and iron is typically better absorbed with a source of vitamin C.
Certified Gluten-Free; Non-GMO; Hypoallergenic
Iron is a core component of haemoglobin and enzymes involved in energy production, supporting oxygen transport and cellular metabolism.
Caution: High intakes may cause gastrointestinal discomfort or constipation; keep away from children due to risk of accidental overdose.
Vitamin C can reduce ferric to ferrous iron and form a soluble complex, which may enhance non-heme iron absorption in the gut.
Caution: May cause stomach upset in sensitive individuals; taking with food can improve tolerance.
Calcium contributes to cellular signalling and bone mineralisation, though this small amount is mainly present as part of the buffered vitamin C form.
Caution: At high doses calcium can compete with iron absorption, but the amount here is low.
Iron bis-glycinate provides a gentle, well-absorbed source of iron for red blood cell support, while vitamin C from calcium ascorbate may improve iron uptake by maintaining iron in a more absorbable form. The buffered vitamin C helps reduce acidity, offering a stomach-friendly profile alongside iron.
Label Warning: If you are pregnant or breastfeeding, have any health condition, or are taking any medication, consult a healthcare professional before use. Accidental overdose of iron-containing products may be fatal in children under 6; keep out of reach of children. In case of accidental overdose, seek medical help or contact a poison control centre immediately.
Who should be cautious: People taking thyroid medications, certain antibiotics, or levodopa may need to separate iron by at least 2 hours as iron may reduce absorption. Those with iron overload conditions should seek medical advice. People with sensitive stomachs may prefer taking with food to reduce discomfort. If combining with medications that may interact with iron, consult a healthcare provider first.
Storage: Store in a cool, dry place.
