Gentle Iron (Iron Bisglycinate) ...

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

Best For

Vegetarians and vegans with insufficient dietary iron intake Women with heavy periods or ongoing menstrual iron loss Pregnant or postpartum women needing a gut-friendly iron source People who have previously experienced GI side effects from standard iron supplements Those with IBS, SIBO, Hashimoto's, or other conditions requiring a highly tolerable iron form Maintenance supplementation after recovering from diagnosed iron deficiency

Pregnancy 30 Tablets + 30 Capsules

Pros

✓High user satisfaction: 100% 5-star ratings with specific praise for energy improvement and comprehensive formula
✓Iodine inclusion recognized by reviewers as important for pregnancy; also contains folic acid as L-methylfolate (bioavailable form)
✓Dual-delivery system (tablets + capsules) allows staggered nutrient absorption and may improve tolerability
✓Active Iron's proprietary technology designed to minimize GI upset common with iron supplementation

Cons

✗No third-party testing certification (NSF, USP, etc.) limits independent verification of label claims
✗Not vegan, limiting options for plant-based diet preferences
✗Limited review volume (only 3 reviews) provides insufficient data to assess prevalence of side effects or long-term tolerability
✗Price point as 'bargain' mentioned by one reviewer suggests may be premium-positioned vs. standard prenatals; value depends on individual budget

Best For

Pregnant women in second/third trimester requiring iron supplementation Women with history of iron deficiency or anemia during pregnancy Those seeking comprehensive micronutrient support in one product Women sensitive to standard iron supplements (Active Iron targets this)

What does the data say about Gentle Iron (Iron Bisg... vs Pregnancy 30 Tablets +...?

Solgar's Gentle Iron uses iron bisglycinate — a chelated form well-known for being easy on the stomach — at 20mg per capsule. Active Iron's Pregnancy pack takes a different approach entirely: a dual-delivery system pairing tablets with capsules, combining iron with folic acid (as bioavailable L-methylfolate), iodine, and other micronutrients in a single pregnancy-focused formula. Solgar scores higher on ingredient quality (90 versus 80), reflecting that bisglycinate is among the most studied and tolerated iron forms available.

If you're not pregnant and simply need a gentle, well-tolerated iron supplement — particularly if you've had GI trouble with other forms — Solgar at £18.84 makes sense. Blood test evidence from users shows real ferritin and haemoglobin gains, though the 20mg dose may require multiple capsules daily for anyone severely deficient, pushing costs up. Active Iron's Pregnancy product at £22.99 is clearly built for a specific purpose: it covers iodine and methylfolate alongside iron, which matters in pregnancy, and the 100% five-star rating suggests good tolerability.

Neither product carries third-party certification, so both require a degree of trust in the brand. Vegans should note Active Iron's Pregnancy formula is not suitable for plant-based diets, whereas Solgar's capsules are vegetarian-friendly.

Gentle Iron (Iron Bisglycinate) 20mg Vegetable 180 Capsules Winner 82.0/100
