Solgar Gentle Iron 25 mg is a reasonable option if you need supplemental iron and that amount fits your clinician's plan. Its main drawback is that iron bisglycinate can still cause constipation or nausea, despite the "gentle" name.

**Keep iron out of children's reach.** Accidental iron overdose can fatally poison children under 6. If a child accidentally swallows iron, call Poison Control or seek medical help immediately.

## Label details for this exact bottle

This review covers the US 25 mg, 90-capsule version, not the UK 20 mg version or the US 180-capsule bottle. Check both the strength and capsule count when buying.

| Label detail | Reviewed US product |
| --- | --- |
| Serving size | 1 vegetable capsule |
| Iron per serving | 25 mg of elemental iron |
| Iron form | Iron bisglycinate |
| Daily Value | 139% |
| Bottle size | 90 capsules |
| UPC | 033984012493 |

The listed iron amount is elemental iron, not the total weight of the bisglycinate compound. The Daily Value is a labeling reference, not an individualized recommendation. This bottle provides 90 one-capsule label servings, not a prescribed 90-day treatment course.

## How to interpret the "gentle" claim

The bisglycinate form alone does not establish that this exact finished product is better tolerated or more effective than other iron supplements. If a previous iron supplement upset your stomach, discuss that experience with your clinician rather than assuming this product will solve the problem.

For the formulation choice, see our [comparison of iron bisglycinate and ferrous sulfate](https://supplementexplained.com/compare/iron-bisglycinate-vs-ferrous-sulfate/). If nausea or constipation is your main concern, the [iron side effects guide](https://supplementexplained.com/safety/iron-side-effects/) addresses those questions.

## Do you need it, and how should you compare value?

Fatigue alone is not a diagnosis of iron deficiency. Ask a clinician about testing to confirm whether you need iron and investigate the cause of any deficiency or anemia. This is not a supplement to add casually "just in case."

For a fair price comparison, compare products at the same elemental iron amount, not by the weight of their iron compounds. Another form may cost less, but your clinical plan and tolerability come before price. Matching milligrams alone is not enough to decide whether to switch formulations.

Check current availability and price for this exact strength and bottle size before buying. If it is unavailable, ask a pharmacist about an alternative that fits your plan.

## When to check with a clinician or pharmacist

If you have known or suspected iron overload, do not start this product without medical guidance.

Iron can interact with levothyroxine, levodopa, and other medicines. Ask a pharmacist to review your medications and supplements and explain any necessary timing precautions.

Check whether your multivitamin or another supplement already supplies iron before adding a separate capsule. If you are choosing a women's multivitamin, our [comparison of versions with and without iron](https://supplementexplained.com/compare/womens-multivitamin-with-vs-without-iron/) addresses that decision.

For use during pregnancy or for a child, get clinician guidance on the product and amount rather than treating the label serving size as an individualized dose.

Our editorial assessment

## Supplement Explained Score

**64**/100

Solgar Gentle Iron 25 mg, 90 Vegetable Capsules

Five equally weighted criteria. This is an editorial assessment, not customer stars, a clinical ranking or a measure of medical effectiveness.

**Label clarity **5/5****

The matched US 90-capsule panel identifies 25 mg elemental iron as bisglycinate in one capsule, separate from the UK 20 mg and larger US packs.

**Research relevance **3/5****

Iron has a defined role when iron need is established. The supplied evidence does not prove that this finished product is universally better absorbed or free of digestive effects.

**Safety and cautions **3/5****

Iron need, overload risks, medicine interactions and potentially fatal accidental child overdose materially limit unsupervised suitability.

**Testing and quality checks **2/5****

The manufacturer label and exact merchant identity are available, but an independently matched finished-product certification or test record was not verified.

**Value for money **3/5****

One-capsule portions and the 90-count pack are straightforward. Current availability and delivered price must be checked; no cost advantage or treatment duration is inferred.

Based on published information, not personal use or laboratory testing by us. Missing testing documentation is not evidence of contamination. Where label versions remain unresolved, the points reflect that limitation rather than assuming a complete current formula.
