Seeing a difference already
"I bought this because I had really brittle and splitting nails. I can see it’s helping already after a few weeks. Have purchased another box. No problems with any stomach discomfort."
Douglas Dietary
Douglas Dietary Carbonyl Iron is essentially pure iron (98%) unlike most other iron supplements which contain iron salts such as iron fumarate and iron gluconate. Iron is used by the body to transport oxygen, and to enable the body to breakdown (oxidize) food components such as starches, sugars and fats to release energy (calories). Iron is also the essential component of haemoglobin in the red blood cells which carry oxygen from the lungs to the tissues.
Studies indicate that people with better iron levels are more likely to achieve their mental and physical potential.
If your iron levels are too low, you may experience tiredness, lethargy and difficulties concentrating. Carbonyl Iron tablets can provide your body with sufficient iron for 3/4 of the maximum recommended daily amount in a single tablet.

"I bought this because I had really brittle and splitting nails. I can see it’s helping already after a few weeks. Have purchased another box. No problems with any stomach discomfort."
"I choose this iron as it is gluten free, dairy free, soy free, etc. . . and it stops my hair falling out"
"I'm chronically iron deficient and this product is the best. I've used it daily for years."
"I've used this product for ages as I have had low iron levels for years. This product is well absorbed in conjunction with esterified vitamin C. And there are none of the usual gut issues normally associated with iron supplements. Basically I can't function without it!"
"I take these with my morning lemon and water drink. I had below average iron levels and following the reviews from on health post I decided to try these since they don’t bung you up. I haven’t tested my iron levels again yet but I feel much better in the brain department and functioning better over all."
"Unfortunately these caused me to be quite constipated even after increasing my water and fibre intake. I already excercise daily, nothing helped."
"My whole life, I had brittle nails, slow growing hair and chronic fatigue. After using this product for several months my nails are so long and healthy they look like I have nail extensions. My hair grows faster, and I am no longer tired. If you have low iron, don't bother with any other brand but this one. . its also the only one that doesn't make your stomach hurt."
"Recovering from COVID was a difficult and long process for me, taking these iron tablets helped shake the extreme fatigue I was experiencing."
"Great product at a great price - buy for my girls. Small tablets easy to take - no constipation 😃"
"A very simple and easy fix for very low iron. I wouldn't be without it."
