Ferrous Sulfate: Why It’s Not Always the Best Iron Option

If you’ve been told to take ferrous sulfate for low iron, you may already know how it goes:

“Take this for your anemia.”
Cue the nausea, constipation, and stomach cramps.

Sound familiar?

At Ask Dr Olz, we see many patients—especially women—struggling with low iron levels and side effects from ferrous sulfate. And we’re here to tell you: you have a better option.

Let’s explore why ferrous sulfate isn’t always the best fit—and how Hemagenics® offers a gentler, more effective solution.

What Is Ferrous Sulfate?

Ferrous sulfate is a commonly prescribed form of iron used to treat iron-deficiency anemia. While it does increase iron levels, it’s poorly absorbed and often harsh on the digestive system.

Common complaints with ferrous sulfate:

• Constipation or bloating
• Nausea or reflux
• Stomach cramps
• Low compliance due to discomfort
• Incomplete absorption

The result? Many people stop taking it—and their iron levels stay low.

Key Ingredients in Hemagenics®:

• Ferrous Bisglycinate (24mg): A gentle, well-tolerated form of iron bound to glycine for enhanced absorption and reduced digestive upset
• Glycine (100mg): An amino acid that supports gut comfort and iron transport
• Folate + B6 + B12: Essential for red blood cell synthesis and methylation
• Copper: A necessary cofactor for iron metabolism
• Thiamin (Vitamin B1): Supports energy and nervous system health

Together, these nutrients work synergistically to:

• Rebuild iron stores
• Improve energy and focus
• Support healthy pregnancy
• Prevent fatigue and brain fog from low iron
