  • Steep price – $44-$55 per bottle
  • Some ingredients are slightly underdosed

SUMMARY: Iron Kingdom eBrain is a supplement designed to improve cognitive functions and mental clarity. Also, it can help you deal with fatigue and stress better.

It contains a promising nootropic formula with some effective ingredients. The main ingredients include Lion’s Mane, Alpha-GPC, Bacopa Monnieri, Ashwagandha extract, and Rhodiola.

The downside of this supplement is that the dosages of 2 main ingredients (Lion’s mane and Ashwagandha) are slightly below recommended effective doses. It also uses Alpha Lipoic Acid which is known to cause side effects in some people. In addition, you can find more comprehensive brain formulas at Iron Kingdom eBrain’s price range.

Still, all five main ingredients are well-researched and should be more than effective. While we don’t rate it as one of the very best nootropics, we do think Iron Kingdom eBrain is a decent brain supplement for people of all backgrounds.

Ingredients – What’s Inside Iron Kingdom ebrain?

Iron Kingdom eBrain Review

The main ingredients in the Iron Kingdom eBrain are:

  • Lion’s Mane (600 mg)
  • Alpha GPC (300 mg)
  • Bacopa Monnieri (300mg)
  • Ashwagandha Extract (200mg)
  • Rhodiola (144mg)

Other ingredients include L-Theanine, Ginseng, Alpha-Lipoic Acid, Caffeine, and Vitamin B1 and B12.

Lion’s Mane

Lion’s Mane is a mushroom that is also known as Yamabushitake. In clinical studies, it showed good results as a cognitive enhancer.

However, the only dosage used in the studies was 3000mg of Lion’s Mane, which means that the 600mg per serving of Iron Kingdom eBrain might not be as effective as the dose used in the study. Nonetheless, the Lion’s Mane is a great ingredient and we are glad it found its place on the ingredient list.


Alpha -GPC

Alpha-GPC is a compound used for its cognitive boosting properties. It supports cellular membranes and can help slow down the cognitive decline in the elders, such as Alzheimer’s disease, dementia, and stroke.


Bacopa Monnieri

Bacopa monnieri is a herb that is known for its cognitive-boosting effect, as well as its stress-relieving and antioxidative properties. In the Iron Kingdom eBrain, it comes in the dose of 300mg, which is the dose that showed the best results.



Ashwagandha is an adaptogenic herb that helps your body deal with stress better. Studies showed that ashwagandha can be helpful in reducing levels of anxiety and stress. Ashwagandha may also be helpful for treating insomnia, fatigue, and minor symptoms of depression. However, more clinical research is needed in order to confirm these benefits.

For best results, the recommended dosage is 300-500 mg of ashwagandha extract, and the Iron Kingdom eBrain contains only 200 mg of the ingredient.



Rhodiola rosea is a herb known for its adaptogenic effects that can be helpful in fighting fatigue, exhaustion, and dealing better with stress. The reported effective dose of Rhodiola goes as low as 50 mg, which makes the dosage of 144mg in the Iron Kingdom eBrain more than enough.


Our Commentary on Iron Kingdom’s eBrain Ingredients

Iron Kingdom eBrain has great nootropic ingredients with clinically proven positive effects on cognitive functions.

Also, all of the ingredients’ dosages are shown on the label, which shows the seriousness of the manufacturer in trying to provide you with a quality nootropic supplement. This is important because a lot of manufacturers try to cut corners and hide the real dosage in their supplements behind a proprietary blend. This allows them to save money by putting less ingredient into the supplement, which can make the supplement less effective.

Although the ingredient list of the Iron Kingdom ebrain is transparent, which is praiseworthy, some ingredients in it, such as ashwagandha and lion’s mane are slightly underdosed in comparison to the recommended dosages that show the best results. This could slightly limit the effectiveness of this nootropic supplement.

Nevertheless, in our opinion, the ingredient list doesn’t look too bad.

User Reviews

The Iron Kingdom eBrain is a pretty new supplement on the market. That means that user reviews you can find on the Internet are pretty limited. To some, that might look like a red flag. However, the most important thing is to look for is the supplement’s ingredient list. Which in this case looks decent and has some quality nootropics.

Pricing & Other Things to Consider

The average prices of the Iron Kingdom eBrain are around $49.99 – $55.99. Since one bottle of it contains 120 capsules and the recommended dose is 4 capsules per day, which is enough for only 30 days, Iron Kingdom eBrain can seem a bit pricey to some.

Side Effects

The ingredients in Iron Kingdom eBrain are generally safe for most people. There is one exception which is Alpha Lipoic Acid, which is heavy metal chelator and shouldn’t be used without consulting your doctor first. ALA is known to cause adverse side effects in certain groups of people. On the other hand, ingredients such as ashwagandha are only known to cause minor side effects such as drowsiness and sedation.

Conclusion to Iron Kingdom eBrain Review

Iron Kingdom eBrain has a promising formula with some excellent ingredients. In our opinion, it’s a solid product if you’re a gamer or someone who needs to keep your brain sharp – but we’ve definitely seen better.

The main downside is that it is pretty pricey and that some ingredients are underdosed, which makes it a bit less effective than what’s currently available out there.
