THORNE Iron Bisglycinate Capsules

The Iron Supplement Formulated for People Who Can't Tolerate Iron

If you've tried iron supplements before and dealt with constipation, nausea, or stomach cramping, you're not imagining it — it's one of the most common reasons people stop taking iron altogether, even when they genuinely need it. Thorne Iron Bisglycinate was specifically formulated to solve this problem: a chelated iron form designed for meaningfully better absorption without the gastrointestinal side effects typically associated with standard iron supplements.

Why Bisglycinate Specifically

Iron bisglycinate is bound to glycine, an amino acid that helps the mineral pass through the intestinal wall more efficiently and gently than standard, non-chelated iron forms (like iron sulfate, commonly used in cheaper supplements). This chelation process is a key reason bisglycinate is associated with higher absorption at a lower dose, and significantly reduced digestive side effects — which is exactly why this product is dosed at 25mg rather than the 65mg found in standard non-chelated iron supplements.

In simple terms: a smaller, gentler dose of well-absorbed iron can be more effective — and more tolerable — than a much larger dose of a poorly-tolerated form.

Why the Lower 25mg Dose Isn't a Downside

It's natural to see 25mg and assume it's "less iron" compared to a 65mg product. In reality, because bisglycinate is absorbed so efficiently, a smaller amount delivers meaningful support without overwhelming your digestive system — this is a deliberate formulation choice, not a lesser one.

What This Supports

• Energy Production — iron is essential for oxygen transport via red blood cells, directly supporting normal energy levels
• Healthy Blood — supports normal red blood cell formation and function
• Gentle, Consistent Use — formulated specifically to minimize the constipation and stomach discomfort common with standard iron supplements
• Cognitive Function — proper oxygen delivery supports normal mental clarity and concentration

Ingredient Breakdown

(Refer to your specific bottle for current serving size, as Thorne periodically updates formulations based on current research.)

Suggested Use

Take 1 capsule daily, with or without food. Unlike standard iron supplements that are often recommended on an empty stomach for absorption (but frequently cause stomach upset as a result), bisglycinate's gentler formulation generally allows more flexibility in timing.

Iron needs vary significantly by individual. If you suspect a significant deficiency, blood work through a doctor is the most reliable way to confirm before starting supplementation.

Comparing All Three Iron Options

If you've struggled with stomach discomfort from iron supplements before, this chelated formula is generally the more comfortable, sustainable option — even at a lower stated dose.
