Searched so long for something stomach friendly
Finally Ive managed a year on iron tablets without them messing with my stomach (these dont trigger reflux vomiting in me). Its not a lot to ask and GP will just tell you to take antacids, but as they reduce absorption of lots of things they arent great if there are other solutions and for me they didnt help stop the vomiting. Ive been on these for a year now, Im still not feeling well but I was very anaemic and had been for a very long time.

Dangerous - take only with medical advice, too powerful
UPDATE - this product is dangerous. I'm weaning myself off excess iron in my body. The NHS (on their website) recommends 8.7mg per day for over 18 men, 14.8mg per day for women 19-50, 8.7mg per day for women over 50. So as an older bloke, I should be getting no more than 8.7mg per day. This pills have 27mg each - three times the daily recommended dose. I believed I was short of iron. In fact, the symptoms of too much iron are ironically similar to too little (fatigue etc) so a vicious circle can develop. Unfortunately, iron is not easy to self-monitor with kits reliably. The NHS website indicates too much iron results in constipation, feeling sick (I was), being sick (not quite) and stomach pain. Other websites e.g. healthline warn "The long-term ingestion of high-dose supplements may gradually cause symptoms similar to iron overload. Iron supplementation is another story. It benefits those who suffer from iron deficiency, but may cause harm in those who are not iron-deficient. Never take iron supplements unless recommended by your doctor." If you must take Iron supplements, do so with under doctor's advice and check out Spatone (a more sensible 5mg per sachet). The best way to get rid of excess iron is to menstruate (difficult being a bloke) or donation (have given dozens of times, but no longer able to) or - I hope - just sitting it out, as I believe I realised fairly early. I knew fat-soluble vitamins can build up in the body (A, D, E, F) but not iron. Be careful, be very careful. ORIGINAL REVIEW - The usual form of iron (fumate) causes constipation and a clear sign that little's being absorbed. Not here - these are fermented with Koji (a rice/soya bean fermented food/pickle popular in Japan). This leads to slower, long-term absorption (hence less tummy upset and constipation) and better absorption in the long run, as is closer to natural iron, e.g. as found in meat products. This, of course, is vegan. Solgar is a top-quality brand and has never disappointed. Rolls Royce quality. Highly recommended.

They work
They did boost my energy levels a bit and helped with tiredness but after taking them for about a week they caused constipation. Had to stop taking them.

Great iron
Brilliant item

They work
Good absorbency. However I did experience stomach lining irritation. I’m sure this is due to having suffered helicobacter pylori recently

Todos lo suplementos de hierro me sentaban mal hasta que llegó este y ha sido una pasada. No noto nada. A ver en unos meses cuando me haga las analíticas

Hay épocas en las que tengo un poco de anemia y en lugar de tomar el hierro que me recetan que me sienta fatal, opto por opciones más naturales. No conocía el koji, pero busqué información y me dió buenas sensaciones, además que la marca ya la conozco y era un plus. Son fáciles de tomar. Estoy contenta con el producto y la relación calidad-precio me parece buena, por ello para mí es recomendable 👍 En Japón al Koji se le conoce como el hongo nacional (Kokkin). Si no fuera por éste y un suplemento anterior, antes no sabía ni que era, así que busqué algo de información. Las enzimas que normalmente se generan al elaborar koji son: proteolíticas, amiolíticas y lipoliticas. ➡️ amiolítica o amilasa: rompe los polisacáridos en azucares simples. ➡️proteolítica o protesa: digiere las proteínas en aminoácidos. ➡️lipolítica o lipasa: digiere las grasas (los lípidos) en ácidos grasos. BENEFICIOS ⬇️ Fácil de digerir. Es probiótico. Beneficios inmunológicos. Restaura flora. Aporta energía

Las está tomando un familiar y me comenta que no le produce nauseas o molestias de estomago como otros. Esto es debido a su forma de obtención natural, el hierro se introduce en el material Koji y es absorbido y almacenado por el cultivo Koji. A través de esta fermentación a base de alimentos, el hierro Koji fermentado proporciona una forma de hierro de liberación más lenta que es suave para el estómago. El Koji o aspergillus oryzae es un hongo que se utiliza como agente de fermentación en la elaboración de muchos alimentos y bebidas ... SIN AZÚCARES ni sal. Sin gluten. No contiene trigo, derivados lácteos, soja ni levadura. Está formulado sin conservadores, edulcorantes, ni aromas o colorantes artificiales. PERO SI CONTIENE CELULOSA MICROCRISTALINA E460i, aditivo sintético usado como estabilizante y espesante. INGREDIENTES: Hierro (como sulfato de hierro fermentado Koji Ultimine) 27 mg, 193% VRN. Agente de carga: Celulosa microcristalina. Capsulas vegetales: Hidroxipropilmetilcelulosa, mezcla de arroz orgánico, extracto de arroz orgánico, goma arábica orgánica, aceite de girasol orgánico. LA DOSIS recomendada es de 1 cápsula al día, contiene 30 Uds tratamiento para un mes (15,39 €). ADVERTENCIAS: La sobredosis accidental de productos que contienen hierro es una de las principales causas de mortalidad en niños menores de 6 años. Por lo que recomiendan mantenerlas alejadas de su alcance.

Se trata de un complemento alimenticio de muy buena calidad, perfecto para personas con anemia y dificultades para su consumo y absorción. Destaca por facilitar la biodisponibilidad del hierro en nuestro cuerpo y ayudar en la asimilación por parte de nuestro organismo.
