A Closer Look at THORNE Iron Bisglycinate

I've taken this iron supplement for a few months now, and it's been a game-changer for my energy levels. Unlike other iron pills I've tried, it doesn't sit heavy on my stomach or cause constipation-probably as it's in the bisglycinate form, which my body absorbs smoothly. The 25 mg dose feels just right for maintaining my iron levels without overloading me, and I appreciate it being gluten-free and NSF Certified for Sport, so I can use it confidently even with my active lifestyle. No more worrying about side effects or questioning whether it's effective.
The packaging is clean and informative, with clear warnings about pregnancy consultation and keeping it away from children, which I respect.I've noticed less fatigue and improved focus, especially after workouts, which aligns with the claims about blood support and resisting fatigue. It's easy to swallow, and I like that it doesn't include common fillers like lactose or magnesium stearate. The only downside is that it's a single capsule per dose, which can be inconvenient if you're used to multi-vitamin tablets.
