Unlike other iron supplements I’ve tried, these capsules are gentle on my stomach and don’t cause the uncomfortable digestive issues I used to experience.

My Buying Guide on Thorne Iron Bisglycinate Capsules
When I first started looking for an iron supplement, I quickly realized how many options were out there. After trying a few, I found that Thorne Iron Bisglycinate Capsules stood out for their quality and effectiveness. Here’s what I learned and what helped me make the best choice for my health.
Why I Chose Iron Bisglycinate
Not all iron supplements are created equal. I wanted something gentle on my stomach because I’ve experienced nausea and constipation with some iron pills before. Thorne Iron Bisglycinate uses a chelated form of iron, which means the iron is bound to amino acids. This makes it easier for my body to absorb and reduces common side effects.
What to Look for in Thorne Iron Bisglycinate Capsules
- Purity and Ingredients: I checked that the capsules didn’t contain unnecessary fillers or allergens. Thorne is known for high-quality, clean supplements, which gave me confidence.
- Dosage: Each capsule typically contains around 25 mg of elemental iron, which fits well with my daily iron needs as recommended by my healthcare provider.
- Capsule Type: I prefer capsules over tablets because they’re easier to swallow and digest.
- Third-Party Testing: I looked for products that are third-party tested for potency and purity, and Thorne meets these standards, which reassured me about their quality.
How I Took Thorne Iron Bisglycinate Capsules
I followed the dosage instructions on the bottle and my doctor’s advice, usually taking one capsule per day with a vitamin C-rich drink to boost absorption. I avoided taking it with calcium or caffeine, as I read these can interfere with iron absorption.
What I Noticed After Using Thorne Iron Bisglycinate
After a few weeks, I felt more energetic and noticed my iron levels improved during my follow-up blood test. I also appreciated that I didn’t experience the stomach upset I had with other iron supplements.
Tips for Buying Thorne Iron Bisglycinate Capsules
- Buy from reputable retailers or directly from Thorne to avoid counterfeit products.
- Check the expiration date to ensure freshness.
- Compare prices but be wary of deals that seem too good to be true.
- Consult with your healthcare provider before starting any new supplement, especially if you have underlying health conditions or are pregnant.
