Optimal Multivitamin with Iron by Seeking Health is a well-rounded daily multivitamin and mineral supplement with high-potency gentle iron and active B vitamins including L-5-MTHF. Optimal Multivitamin with Iron has been carefully developed to contain the right proportions of vitamins, minerals, trace elements, and other nutrients.*

Like our popular Optimal Multivitamin formula, each ingredient in Optimal Multivitamin with Iron is chosen with its absorption, competitive relationship with other nutrients, allergenic potential, and long-term safety taken into account. B vitamins including riboflavin, B6, B12 and folate are included in their active coenzyme forms for optimal absorption and utilization. Benfotiamine, a well-absorbed, fat-soluble form of thiamine, is included to support healthy nerve and muscle function.*

Trace minerals such as zinc, selenium, and chromium are important components of this formula as they are needed for numerous chemical and electrical processes in the body. Typically taken up from the soil by plants, trace minerals may be lacking in the modern diet due to decreasing nutrient content in the soils used in commercial farming. Iron is a well-known mineral that plays an important role in the transfer of oxygen from the lungs to other tissues in the body through the blood. Amino acid-chelated forms of these minerals, such as Ferrochel® gentle iron and others used in this formula, are typically well-tolerated and easier on the stomach than other common supplemental forms.*

For a similar product in a delicious powder format, consider our Optimal Multivitamin Powder. For a multivitamin capsule without iron, consider our Optimal Multivitamin Plus. For a specialized multivitamin for children, consider Kids Optimal Multivitamin.

Suggested Use

Take 4 capsules daily with food or as directed by your healthcare professional.


Children and pregnant or lactating women should consult their healthcare practitioner prior to use. Do not use if full-bottle shrinkwrap is broken or missing. Avoid if allergic to any ingredient. Do not exceed 5,000 IU intake per day of preformed vitamin A. Evaluate total vitamin K intake from food and supplements if you are taking blood-thinning medications. Consult a healthcare professional prior to use if you are taking any medications (esp. antibiotics) or if you are undergoing treatment for any medical condition. Consult with a healthcare professional to determine whether iron supplementation is necessary and suitable for you. When taking high levels of iron, use under the care of a qualified physician and track blood levels. Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6. Keep this product out of reach of children. In case of accidental overdose, call a doctor or poison control center immediately.

I had taken multivitamins for years without iron and had always assumed that I was getting enough from my diet. Then I started to feel sluggish and had blood work down and found that my ferritin level was low. Since I’ve started taking this I feel better than I have in a long time. Review by FJ (Posted on 7/12/2018)
Great multivitamin!
It’s not easy finding a good quality multivitamin with iron. This one from SH is great. The iron is gentle on the stomach and does not cause any issues for my wife. It has helped boost her iron levels. She really loves it. Review by SN (Posted on 7/9/2018)
Great supplement, decent flavor, easy to digest. Review by Amy (Posted on 6/8/2018)
Great vitamin
Easy to swallow with many important vitamins and minerals. Downside is that 4 caps is the daily dose. Review by Hollee (Posted on 4/5/2018)
Excellent product
I like how the dosage is spread over multiple capsules. Sometimes I don't want a full hit and other times I do. Much easier to personalise and pulse. Ib haven't felt the gross effects from the iron like I do other iron supplements, either! Review by Loleney (Posted on 3/12/2018)
So effective!
I've been ordering SeekingHealth products from Japan. It's not easy job to import those supplements from abroad and it's definitely not my favourite thing to calculate shipping costs & custom tax etc. to optimise them as much as I can... But I have to say that I cannot find any replaceable supplements that are the same or better quality in Japan! They are just not reliable at all! I got to know about SeekingHealth a few months ago when I was experiencing a serious physical corruption and it was amazing to see how my body started to recover so fast from the critical condition as soon as I started to take the SH supplements. So grateful to have SH in my life! Review by Ayaka (Posted on 1/29/2018)
Great product.
I recently found out I was extremely low in iron . I was always tired but shrugged it off as the normal thing since I am a mother of three young children. After taking this muti vitamin for only 1 week I noticed I wasn't even reaching for my second cup of coffee in the afternoon. My energy is back to what it used to be and I don't get nausea from the pills either as I have with previous mutivitamins with iron. I'm very happy with this product! Review by Marina (Posted on 1/4/2018)
Love this multi!
This is my favorite multi. The only thing that would make it better in my book would be to make all the minerals TRAACS formulations. Still, it's a great vitamin and I simply cannot take 6 or 8 additional pills per day. Review by Chryste (Posted on 10/30/2017)
Great multivitamin.
Good product--like that it has iron in it (since I was iron deficient and have to take iron pills anyway) and also the methylated form of folate. Review by Anita (Posted on 8/26/2017)
Gives me energy
This product is just what I wanted. I take just two a day and I have realized an increase in energy. I have learned not to take more than two or three in a day and not too late in the day or it will keep me awake at night. But maybe that's just me! Review by Hollee (Posted on 6/3/2017)
Excellent product
Excellent product at a great price!!! Review by Steph (Posted on 1/28/2016)
Great Product!
I keep this on hand to take when I know my iron levels are low. It's so potent, I only require half a dose and I'm all set! It is a great broad spectrum multivitamin. Try it! You won't be disappointed! Review by Great Product! (Posted on 7/19/2015)
These are the best multivitamins I've taken since I don't remember when! It usually takes a long time or tests to tell if a multivitamin is really working but I could tell that these were working fast. I've been forcing myself to eat a little something a few times a day but not really feeling hungry or wanting food most days. These have given me my appetite back. Review by LisaW (Posted on 12/16/2014)
Great for Pregnancy!
I've used these vitamins for a couple months now. I'm pregnant with my second child and have MTHFR, A1298C Heterozygous as well as Hypothyroidism. My midwife recommended these over Folgard for my Folate intake. I feel much more confident taking these than a prescription which is filled with other things that maybe unhealthy for my baby. I've felt no adverse side effects. I've also used this as a replacement for my prenatal vitamins, so I've replaced what used to be 2 vitamins in 1! I've had more energy, however I'm also in my second trimester now which helps too:) Review by Carey (Posted on 1/21/2014)
