Gentle Iron (Iron Bisglycinate) 20mg Vegetable 180 Capsules vs Gentle Iron 20mg 90 Vegi Capsules

Pros

• ✓Iron bisglycinate form is exceptionally gentle — virtually no constipation or GI irritation across the large majority of reviewers
• ✓Multiple users confirm measurable ferritin and haemoglobin improvements via blood tests
• ✓Widely reported improvements in energy levels, reduced fatigue, and better hair condition
• ✓Certified vegan, Kosher Parve, Halal, Non-GMO, gluten-free, and dairy-free — suitable for restricted diets

Cons

• ✗20mg dose is conservative and may be insufficient for severe iron deficiency without taking 2–4 capsules daily, which increases cost significantly
• ✗Not third-party tested for purity or label accuracy
• ✗Requires avoiding calcium-rich foods or supplements near dosing time and ideally co-administration with vitamin C — some find this inconvenient
• ✗Isolated reports of digestive upset, suggesting individual tolerance still varies
