Product Overview

Iron is an essential mineral that plays a critical role in oxygen transport, energy production, and overall vitality. However, many iron supplements cause unpleasant side effects like constipation, nausea, and stomach upset. THORNE Iron Bisglycinate offers a superior solution with its unique bisglycinate form—iron bound to the amino acid glycine—which enhances absorption while being gentle on the digestive system. Each capsule provides 25 mg of elemental iron, making it a potent yet well-tolerated option for maintaining healthy iron levels.

Key Features and Benefits

  • Enhanced Absorption: Iron bisglycinate is chelated to glycine, allowing for efficient uptake without competing with other minerals. This form is less likely to cause gastrointestinal side effects compared to ferrous sulfate.
  • NSF Certified for Sport: Third-party tested to ensure it is free from banned substances, making it a trusted choice for athletes and active individuals.
  • Gentle on the Stomach: Designed to minimize common iron-related issues like constipation, bloating, and nausea, so you can supplement without discomfort.
  • Gluten-Free and Hypoallergenic: Free from gluten, dairy, soy, and other common allergens, suitable for sensitive individuals.
  • 60 Servings per Bottle: A two-month supply at one capsule per day, offering convenience and value.

How to Use

Take one capsule daily with or without food, or as recommended by your healthcare professional. For optimal absorption, avoid consuming iron with calcium-rich foods, coffee, or tea. If you are taking other supplements or medications, consult your healthcare provider to ensure proper timing and dosing.

Who It Is For

THORNE Iron Bisglycinate is ideal for individuals with increased iron needs, including those with iron deficiency, athletes, vegetarians, vegans, and women with heavy menstrual cycles. It is also suitable for anyone seeking a high-quality, well-absorbed iron supplement without digestive distress. Because it is NSF Certified for Sport, competitive athletes can use it with confidence.

Why Choose This Product

Not all iron supplements are created equal. THORNE is a trusted brand among healthcare professionals and consumers alike, known for its commitment to quality and purity. The bisglycinate form is backed by research for superior absorption and tolerability. Additionally, NSF certification provides an extra layer of assurance, especially for those subject to drug testing. With THORNE Iron Bisglycinate, you get an effective, gentle, and safe iron supplement that supports your energy and overall health.
