zhou nutrition iron beard

The Iron Beard by Zhou Nutrition is quickly becoming one of the big players in the beard growth supplement industry.

I have previously talked about this brand on my post about biotin for beard growth, where I did highlight their earlier supplement called the Hairfluence (which was basically a multivitamin with high biotin and some other stuff).

Well, this Iron Beard is their newer beard growth product specifically, and they claim it would make your beard grow stronger, faster, and thicker.

I have some issues with that claim – and you’re about to find out why below.

But before we move on, I want to say quickly that this will not be like your usual online reviews. You see, people who review supplements online always hype up all minimal benefits, and just ignore all the obvious negative factors.

This is because they tend to be affiliated to the products they review, and when people buy, they earn a nice commission as well, which causes them to hype up even the bad products in hopes of some quick money.

“This review won’t be like that. I do not earn a commission from the company and I won’t be skipping over the negative parts.”

In this Iron Beard review. I will be mentioning the good and the bad stuff 100% honestly, so you can know if you can really expect your beard to grow better after taking it.

Let’s get to it. ↓

Iron Beard Ingredients Explained

iron beard ingredients

The Iron Beard is a very basic multivitamin if you look at the ingredient list, but it does have some extra stuff in it, such as few herbs and some extracts.

As you probably already know, vitamins and minerals can benefit your beard growth by providing vital nutrients to the follicles and by supporting the production of the hormones that regulate facial hair growth – Testosterone (T) and Dihydrotestosterone (DHT).

So in this sense, Iron Beard has done a decent job by including stuff like the vitamins A, C, D multiple B-complex vitamins, and zinc…

But they also missed some of the important ones like vitamin E, boron, magnesium, calcium, and selenium, all of which would greatly benefit the beard.

Then there’s the 300mg proprietary blend called “The Iron Beard Complex”.

“This blend in my opinion, is the biggest flaw of the whole supplement, and the reason I can’t ever recommend it to anyone with a straight face.”

You see, beard growth is regulated in part by the hormone dihydrotestosterone (DHT) which is known of causing hair loss on the top of the scalp (which is not androgenic-hair), but also promoting it on the beard area (which is androgenic-hair).

And two of the ingredients in Zhou Nutrition’s Iron Beard, are in fact powerful DHT-blockers.

Yes, you read that right.

The formulation contains ingredients that can help block one of the most important hormones that your beard needs to grow.

These ingredients are saw palmetto (here’s a study of it lowering DHT) and pumpkin seed extract (here’s a study where it too lowered DHT).

To make it crystal clear…

More DHT = Better facial hair growth, but worse scalp-hair growth.

Therefore the Iron Beard should instead be marketed as a scalp-hair supplement, and definitely not as a beard supplement.

So why exactly did they formulate these beard growth suppressing ingredients into a pill that is supposed to help beard growth?

Well, I think they just read stuff about scalp-hair loss, and mistakenly thought that lowering DHT would be as good for the beard hairs as it is on the scalp-hairs.

They couldn’t be more wrong though. DHT is the hormone responsible for your linear beard growth, and reducing it will certainly not help your beard grow.

You simply cannot make a mistake like that. It appears as if they just relabeled a scalp-hair supplement for beard use, which is wrong in so many ways, as scalp hair IS NOT androgenic-hair. This is the second beard supplement I see making the same mistake, the other being Beard Grow XL.

Iron Beard is Somewhat Expensive (Price-per-Capsule)

money growing from ground

There are 60 capsules in the Iron Beard with the serving size of 2 capsules per day.

Price-wise, it’s almost on par with its biggest competitors; the Vitabeard and the Beardilizer.

With the price of $20, this means that the cost per capsule will be $0.33 which is quite high for a supplement that has a small number of vitamins and minerals, and a herbal blend that likely hurts instead of helps your beard to grow.

For comparison, you could get a higher amount of vitamins and minerals – without the beard growth suppressing herbal blend – for about $0.09 per capsule if you just bought a basic multivitamin supplement like this one from Amazon.

Just like with all the other popular beard growth vitamins, you could get much more bang for your buck by simply getting a basic multi that does not have the beard logo or “beard” text in the bottle.

Iron Beard Reviews, Before-Afters, and More

pros and cons

We already know that the Iron Beard supplement can’t really grow you a better beard since it has DHT blockers (it could work well as a scalp-hair supplement thought).

But the thing is that the people who buy the supplement for their beards don’t often understand the role of DHT, and have no idea what they’re taking.

Even with that, there are still tons of poor reviews which state that the product simply did not help them grow more facial hair.

Mixed in are raving five-star reviews which say that it was the best thing since sliced beard, and you can usually spot these as fake and paid reviews (they say things like “Have patience!”, “Best beard vitamin ever!”, “Wife loves the new growth”, etc).

There are also some before-afters from customers in their reviews on Amazon for example. None of them show any new growth at all (as to be expected, since they formulated them mistakenly with DHT-blockers because they thought scalp-hair is the same as beard hair).


It’s a scientifically proven fact that DHT grows beard hairs and is one of the most important hormones for maintaining your natural facial hair growth.

Iron Beard claims to be a specially formulated beard growth supplement, yet it has two proven DHT-blockers in its ingredients.

By this fact alone, we can conclude that it is not a good beard supplement, and definitely not recommended by us.

It’s a shame, and we think they must have formulated the DHT-blockers into their product accidentally, by thinking that the same stuff that grows the hair on the scalp, would also benefit the androgenic facial hair (which isn’t the case).

Their vitamin blend is OK and it alone would probably help your beard to grow a bit better, but with the saw palmetto and pumpkin seed extract in it, we simply cannot recommend the Iron Beard by Zhou Nutrition.

For the same price as this supplement, you could get one of the highest quality multivitamin supplements ever formulated, and that would be our recommendation instead of any “special beard growth pill”.
