Written by Andrew Le, MD

UpdatedOctober 23, 2024

Iron is an essential micronutrient required in the production of hemoglobin, which is a protein that is in the red blood cell and transports oxygen from the lungs to various tissues. Lack of sufficient iron in the human system hinders the creation of healthy red blood cells hence iron deficiency (anemia). Iron supplements can aid in the raising of this mineral in the body, but with so many brands present in the market it is challenging to decide which is the best to use.

In this article, we review the best OTC iron supplements to help you make a decision. Read on

Top 3 Best OTC Iron Supplements

  1. Vitron-C Iron Supplement
  2. Flamingo Supplements Iron Gummies
  3. NATURELO Vegan Iron Supplement

To help you decide, here are some of the top over-the-counter iron supplements in the market today.


Vitron-C Iron Supplement

Editor's Choice

Vitron-C Iron Supplement

Our top choice is the Vitron-C iron supplement. It is easily absorbed and boosts the levels of iron in the body, not to mention it's one of the best OTC supplements.

See Price on Amazon

Now, if you are in search of the best iron you can get, Vitron-C is highly recommended. We strongly encourage the use of this product due to its concentrated formula and assimilation by the body.
We have used Vitron-C iron supplements ourselves and have noticed that energy levels increase. Another advantage is the Vitamin C reinforcement that facilitates iron retention in the body something that is critical for anyone with poor iron status. Notably, the client should know that this product contains no dye, gluten or is vegan hence serving a number of users.

Pros

  • Boosts energy by fighting fatigue
  • Contains Vitamin C to improve iron absorption
  • Dye-free, gluten-free, and vegan

Cons

  • May cause constipation in some users
  • Large pills may be difficult to swallow
  • Some users may experience stomach upset

All the same, it is worth understanding that some consumers face problems like constipation or upset stomach after intaking iron supplements. Moreover, the pills are big in size, making it slightly irresistible for some of the users to swallow whole. Although, these may be some negative implications, we think that the advantages of using Vitron-C are more important.

In summary, it is wise for people who want to increase their energy levels and consume more iron to use Vitron-C iron supplements.


Flamingo Supplements Iron Gummies

Flamingo Supplements Iron Gummies

We’ve been using the Flamingo Supplements Iron Gummies Plus Multivitamin, and we’re impressed with its convenience and effectiveness.

Pros

  • Vegan and kosher-friendly.
  • Includes other essential vitamins like zinc and B complex.
  • Suitable for all ages, including prenatal women.
  • Tasty and easy-to-chew gummies.

Cons

  • Only 60 gummies per bottle, a 30-day supply.

The Flamingo Supplements Iron Gummies Plus Multivitamin includes 10 mg of iron per serving, along with Vitamin C, zinc, and B complex to enhance overall health and improve iron absorption. Biotin adds an extra boost for hair, skin, and nail health. The gummies are vegan, kosher, and free from common allergens like gluten and dairy, making them suitable for various dietary needs.

NATURELO Vegan Iron Supplement

NATURELO Vegan Iron Supplement

See Price on Amazon

For the best iron supplement, we therefore recommend the NATURELO Vegan Iron Supplement.

Pros

  • The iron supplement is gentle and doesn't cause nausea or constipation.
  • The advanced bioavailability formula ensures better absorption of iron.
  • The iron supplement is doctor-recommended for individuals with common iron deficiencies.

Cons

  • The capsules are relatively large and may be difficult to swallow for some users.
  • The supplement may cause stomach upset in some users.
  • The price is slightly higher than some other iron supplements on the market.

I have been using the NATURELO Vegan Iron Supplement for some weeks and can say that I have much more energy now. The supplement is not harsh and does not upset the stomach unlike how most other iron supplements are known to do.

The supplement offered by NATURELO is to support the body with iron while being 100% non-heme; that is why the bioavailability formula used by the company here is quite advanced in comparison with iron-based products. More incorporation of vitamin C boosts the absorption of iron and therefore can yield better outcomes.

We also like it because it is a doctor’s recommended formula that is suitable for people with general iron deficiencies like pregnant women, girls with their periods, vegans, vegetarians, dialysis patients, people who regularly donate blood, anemic guys or ladies, and many more.

The only challenge that I can think of is that the capsules are relatively large, which may not be easy to swallow especially to some of the clients. Also, there are the side effects of the supplement, which include stomach upset among some users. Last but not the least; the price tag is slightly higher than you may find with other iron supplements.

In conclusion, it is worth choosing the NATURELO Vegan Iron Supplement as the best iron supplement on the market. It’s mild, efficient and prescribed by doctors that’s why it is perfect for people with standard iron depletion.

Buying Guide

When choosing an over-the-counter (OTC) iron supplement, there are several factors to consider. We recommend looking at the following features before making a purchase:

Form of Iron

The forms of iron supplements are ferrous sulfate, ferrous fumarate, and ferrous gluconate, to mention but a few. Ferrous sulphate is the most commonly used iron preparation and is usually the cheapest as well. Ferrous fumarate and ferrous gluconate are also effective, though they may be slightly more costly than ferrous sulfate. The form selected should be one that is assimilated by the body with relative ease.

Dosage

Another precaution that must be taken is to ensure that one consumes the recommended quantity that is stated on the container. Having excessive amount of iron is dangerous so it is advisable not to go overboard while taking the supplement.

Additional Ingredients

Extra additives that may be present in some of the iron supplements include, vitamin C or folic acid. Vitamin C is needed to assist in iron absorption while folic acid will assist in preventing anemia. If you have any sort of health consideration or deficiencies, then consider going for a supplement with extra special ingredients.

Price

The cost of iron supplements may vary from cheap to expensive depending on the form, dosage, and other ingredients. When deciding which supplement to take, you must put the budget into consideration. Always bear in mind the fact that the supplement that is most costly may not be the one that suits you the best.
