Iron Benefits: Boost Brain, Immunity, and Skin Health

What are the Benefits of Iron

Benefits of Iron

Aids Brain health

The brain requires enough oxygen-rich blood to function optimally. One of the iron benefits for the body is oxygen transportation and neurotransmitter synthesis^[1].

This means that when you are able to regulate and maintain the necessary balance of iron in the body, it will have a positive effect on the brain's physiological functions.

In this video, our valued client shares her experience with WOWMD Neuro Plus Brain & Focus Formula, highlighting how the supplement has improved her mental clarity, enhanced focus, and supported overall brain function.

Boosts Immunity

One of the essential nutrients that help ensure you are able to be healthy and active daily is iron. Since it helps with oxygen transportation, less iron means less oxygen in your body system. Iron deficiency will further affect other body functions, including the immune system.

According to research published in the National Library of Medicine, iron deficiency and excess can affect the functions of your immune system^[2].

Healthier Hair

Iron helps the body produce hemoglobin, a protein responsible for transporting oxygen to your body cells^[3]. Part of the body cells are the ones responsible for hair growth.

One of the benefits of iron on the hair is the improved growth, as long as you are able to maintain the level of iron in the body.

In addition, iron supplements for females ensure they don't have to deal with hair loss. A study conducted on 210 patients to investigate the relationship between iron and hair loss suggested that iron may play some role in the premenopausal female pattern of hair loss^[4].

Iron is vital for healthy skin, hair, and nails. Deficiency can lead to pale skin, brittle nails, and thinning hair. The video here explains how to boost iron levels with diet and supplements.

Reduced Fatigue

One of the iron benefits for males is the supply of energy, especially in active males. Iron ensures a supply of oxygen around the body, and the body uses the oxygen for energy to help ensure you don’t feel fatigued.

A study concluded that iron supplementation helps improve mood, stress, and fatigue in nonanemic endurance athletes^[5].

Did You Know?

• Iron aids in collagen synthesis for healthy skin.
• It boosts brain function and oxygen delivery to cells.
• Women need more iron than men, especially during menstruation.
• Heme iron from meat is more easily absorbed than plant-based non-heme iron.

Iron Nutritional Facts

Although iron is mostly found in the hemoglobin, it is also found in every cell in the body^[6].

Women require more iron intake than men. Women between 19 and 50 need a daily dose of 18mg, while men in the same age range, 19 and older, only require 8mg per day.

Women eating plant-based diets tend to consume more iron, but have higher rates of iron deficiency anemia, as non-heme iron, mostly found in plants, is not as well absorbed as heme-iron, found in meat products^[7].

Iron-deficiency anemia is the most common nutrient deficiency in the world^[8].

Stephanie Weinberg Levin, M.D., a psychiatrist at Michigan Medicine and the VA Ann Arbor Healthcare System, says, "Iron is the most common nutrient deficiency and can have a big impact. You can be iron-deficient without having anemia, but many mental health care providers aren’t aware that iron deficiency by itself has been linked to worse symptoms or that supplementation has been linked to improved symptoms. But there is evidence there."

Recommended Daily Iron Dosage

While iron is important to the body, you need to ensure it is not deficient and also not in excess. How much iron per day depends on your age and sex. The National Institutes of Health recommends daily allowances for iron^[9].

List of Iron-Rich Food

List of Iron-Rich Food

There are different forms of iron: heme and non-heme. Heme iron is present in fish, poultry, and meat. Examples of heme iron-rich foods are:

• Beef
• Lamb
• Ham
• Turkey
• Chicken
• Oyster
• Clam
• Canned light tuna
• Pork, and many more.

On the other hand, non-heme iron is present in plant-based foods like fruits, nuts, and vegetables. Examples of non-heme foods are^[10]:

• Strawberries
• Watermelon
• Raisins
• Spinach
• Sweet potatoes
• Dark chocolate
• Enriched rice or bread
• Kale, and many more.

Is Iron Safe?

Iron is important for many people, especially when their body needs extra support. But too much iron can be harmful. If your iron levels are already good, taking extra iron may cause problems like oxidative stress, which can harm your cells.

Taking too much iron can also lead to iron poisoning, which is serious and even life-threatening. That’s why it’s always a good idea to check with a healthcare provider before starting an iron supplement.

Side Effects of Iron

Iron supplements are helpful for many people, but they can come with some side effects. Here are a few common ones:

• Constipation
• Nausea
• Diarrhea
• Vomiting
• Dark-colored stools

Some types of iron are more likely to cause these issues. For example, ferrous sulfate, a commonly used form, can cause constipation and nausea more often than other forms like iron bisglycinate.

Taking too much iron, especially in high doses or every day, can increase the chances of experiencing these side effects.

If you feel uncomfortable, it’s a good idea to talk to your healthcare provider. They may suggest a different form of iron or adjusting the amount you take. In some cases, taking iron less often could help.

Very high levels of iron can cause serious problems, such as heart issues and kidney damage. Always follow the recommended dosage and check with your healthcare provider if you're concerned.

What To Look For

When buying an iron supplement, choose trusted brands that follow strict safety rules. Look for products that are certified by organizations like the U.S. Pharmacopeia or NSF International, which ensure the supplements are safe and effective.

Pick a supplement that works best for you. If you have trouble swallowing pills, you can try liquid or powder forms.

Unless a doctor says otherwise, avoid taking high-dose iron, as it’s not needed for most people. Always choose quality, ease, and the right amount when picking your iron supplement.
