Ingredient

Iron for energy and healthy blood, delivered by live probiotics.

An essential mineral that carries oxygen in your blood, fights tiredness, and supports daily energy.

What it is

Iron is an essential mineral your body needs to make red blood cells and carry oxygen to every organ. In Velobiotics products, gentle forms of iron (like ferrous bisglycinate) are combined with vitamin C and friendly bacteria. This gentle combination helps your body absorb iron easily without causing stomach pain or constipation.

Also known as: Ferrous Fumarate, Ferrous Bisglycinate, Gentle Iron

Key benefits

  • Helps red blood cells carry oxygen around your body so you feel energetic and alert.
  • Stores oxygen in your muscles so you can stay active and recover after exercise.
  • Drives cellular energy production so your body can combat tiredness and fatigue.
  • Supports healthy immune cells and sharp mental focus so you stay well.

Amplified by probiotics

Plant and supplement iron can be hard for your stomach to absorb and may cause constipation. Friendly probiotic bacteria produce natural acids that make iron easier to dissolve and absorb into your bloodstream. Probiotics also break down plant compounds that trap iron, while calming gut inflammation so your stomach stays comfortable during iron intake.

Typical dose

14–45 mg/day (elemental iron)

The evidence

Evidence: strong

Clinical studies show that taking gentle iron alongside probiotic bacteria boosts iron absorption and raises blood iron levels faster. Trials confirm that this combination significantly reduces common iron side effects like stomach cramps and constipation.

Safety & who should check first

Iron is safe at recommended daily amounts. High doses may cause dark stools, mild nausea, or constipation. Keep all iron supplements strictly out of reach of children, and consult a doctor or pharmacist if you have an iron-storage disorder.
