NutraBio has been gradually refreshing and modernizing its extensive catalog over the last year or so, updating products one by one with a cleaner, modern visual identity and, in some cases, more meaningful changes beneath the label. The latest supplement stepping into that transition is Fe, previously sold as Iron Chelate, which has now been reintroduced as Iron Glycinate. Alongside the updated name and packaging, NutraBio has also increased the amount of iron you get.
The previous version of the supplement relied on chelated iron for 18mg of iron, while the refreshed Iron Glycinate specifically utilizes highly bioavailable, Ferrochel-branded ferrous bisglycinate chelate, providing 38% more iron at 25mg. That form is widely known for improved absorption and gentler digestion compared to traditional iron sources, helping support energy, endurance, oxygen transport, and focus. NutraBio’s revamped Iron Glycinate is now available directly through nutrabio.com at $13.99 for a bottle of 60 capsules, lasting you two months when used once a day.
