Product Overview

I recently tried Thorne Research Iron Bisglycinate 25 mg Optimal Absorption and I am impressed with this product. I have tried a lot of iron supplements in the past, but this one is unique in its ability to provide optimal absorption. It comes in a capsule form, which makes it very easy to swallow and digest.

The main benefit of this product is that it provides 25 mg of elemental iron per capsule in a non constipating, well absorbed form as iron bisglycinate. This means that it can be easily absorbed into your body, giving you the energy you need to get through the day without feeling fatigued or run down. Additionally, this product helps fight fatigue and other signs of an iron deficiency which can manifest as weakness, shortness of breath, dizziness, tinnitus, drowsiness, irritability, infrequent menstruation and loss of libido.

This product is also certified for sport and supports high performance nutrition programs. It is NSF Certified for Sport and Thorne has partnered with 11 U.S. Olympic Teams to provide quality supplements to help athletes reach their goals. Furthermore, Thorne has collaborated with Mayo Clinic on wellness research and content so you know that you are getting a trusted and reliable product when you purchase from Thorne Research Iron Bisglycinate 25 mg Optimal Absorption.

In terms of tech specs, the product dimensions are 2.09 x 2.09 x 3.72 inches 0.32 Ounces so it doesn t take up too much space when storing it at home or on the go if needed.

Overall, Thorne Research Iron Bisglycinate 25 mg Optimal Absorption is an excellent choice for those looking for an iron supplement with optimal absorption capabilities. Not only does it provide essential minerals for blood building but it also helps fight fatigue and other symptoms associated with iron deficiency while still being certified for sport use by 11 U.S Olympic Teams and NSF Certified for Sport programs making it a reliable choice when considering purchasing an iron supplement.
