Ferrous Bisglycinate
Iron
Oxygen & Energy
What it does
Iron is the mineral that lets your blood carry oxygen to every cell, so when it runs low, the first sign is usually fatigue, breathlessness, or feeling cold. It's one of the most common deficiencies in menstruating women. We use the bisglycinate form, which delivers the energy benefits of iron without the constipation that classic iron pills are known for.
The science
A gentle, non-constipating form of iron vital for the production of hemoglobin, enabling efficient oxygen transport from the lungs to systemic tissue.
Most relevant for
Menstruating women, plant-based eaters, and unexplained tiredness. Only supplement iron if you're low; test first.
