A healthy head of hair is a very defining feature, which is why many people seek to keep their hair as healthy and strong as possible for as long as they can.

Within this, a lot of folks are turning to hair growth supplements to potentially restore their hair to a stronger, more youthful state. 

But of course, it’s important to analyze if these supplements actually work! And in this review, we’re going through one product called B40 Trufolix to see how it truly stacks up as a hair health supplement. 

B40 Trufolix Review Highlights

  • B40 Trufolix has a good line-up of research-backed ingredients proven to actually work
  • There is a proprietary blend so we can’t tell how much of certain ingredients are in there
  • You’ll pay around $1.50 to $2 per serving, which is pretty moderate for a hair supplement
  • Like with any hair supplement, the results will take time (likely a few weeks at least)

Each capsule of B40 Trufolix contains a blend of herbs, polyphenols, vitamins, and minerals, which they say create the ideal environment for promoting stronger, fuller, and healthier hair. 

This formula is designed to improve hair growth and hair health from multiple angles, such as by decreasing inflammation, providing key nutrients, supporting hormone levels, and reducing hair shedding, among other things. 

Altogether, B40 Trufolix Hair Growth and Strengthening Capsules are designed to be just what you need for a healthier head of hair again.

B40 Trufolix Benefits

B40 Trufolix is advertised to offer several pivotal benefits that ultimately lead to optimal hair. These are:

  • Hair Growth & Thickness Support
  • Lower DHT Levels
  • Healthier Scalp

Hair Growth & Thickness Support

One of the main claims of B40 Trufolix is that it will increase hair growth and thickness. This is mainly due to a variety of included nutrients that they say enhance hair growth, including biotin, silica, vitamin D, and a specific probiotic called Lactobacillus plantarum. 

Decreased DHT Levels

Another advertised benefit of B40 Trufolix is decreased DHT levels, which they say leads to other benefits. Specifically, the ingredients in the TruFolix complex are designed to lower DHT, which in turn supports hair follicle health, decreases oxidative stress, and reduces the chance of hair thinning.

Some of the main ingredients in this complex are green tea, turmeric, and banana flower stamen. 

Healthier Scalp 

B40 Trufolix is also designed to promote a healthier scalp, mainly by decreasing inflammation and oxidative stress and supporting follicular health. As a result, a healthier scalp can make hair grow quicker and easier while reducing the chances of hair thinning. 

Overall, B40 Trufolix is an intriguing choice for hair at first glance.

But does this formula actually work as advertised?

Let’s continue below to find out!

TruFolix Complex (1,236.2mg)

The main component in B40 Trufolix is the TruFolix Complex, which consists of:

  • Banana Flower Stamen Extract
  • Green Tea Leaf Extract (90% Polyphenols)
  • Lactobacillus Plantarum
  • Turmeric Extract (95% Curcuminoids)
  • BioPerine® Black Pepper Extract
  • L-Cysteine
  • L-Methionine
  • Taurine

So, it’s essentially a mixture of herbal extract, amino acids, and a probiotic. 

Banana flower stamen, green tea leaf, and turmeric are all rich in antioxidants and anti-inflammatory compounds. Plus, specific clinical research on banana flower also shows that it can decrease DHT, reduce oxidative stress, stimulate hair growth, and decrease the activity of hair loss genes. 

Next, we see lactobacillus plantarum, which is a type of probiotic (or “good bacteria”). This bacteria can improve gut health, enhance immunity, and promote overall wellness. Related to hair, research also shows that this probiotic can increase hair cell activity, reduce inflammation, and improve scalp health, which can all lead to improved hair growth. 

Also, there are three key amino acids: cysteine, methionine, and taurine. There is evidence that these amino acids are implicated in hair health in various ways. For example, they are key components in follicular health, anti-inflammatory pathways, and the overall balance between hair loss and hair growth. 

Lastly, BioPerine® is a trademarked form of black pepper extract. It has been shown to enhance the bioavailability of other ingredients, such as turmeric and green tea. So this could lead to greater effects for those compounds. 

Vitamin D3 (150 IU)

Vitamin D is an essential vitamin, and research shows it is also important for maintaining a healthy scalp and hair. If you don’t get enough, this increases the risk of hair thinning. 

Vitamin E (5mg)

Vitamin E is mainly potentially beneficial for hair due to its antioxidant and anti-inflammatory properties, which could support scalp and hair health. 

Vitamin B6 (1.7mg)

Vitamin B6 plays a number of roles related to metabolism, hormone signaling, and other factors that may affect hair growth. Overall, it seems important to get enough vitamin B6 if you want to decrease the risk of hair loss. 


Biotin (less commonly known as vitamin B7) is featured in many hair and nail supplements, such as Hum Hair Sweet Hair

This vitamin plays a role in many metabolic pathways. And research does show that it can improve hair (and nail) health in people with a biotin deficiency or specific hair/nail damage. But it’s unclear if it really causes hair growth in already healthy people.

Magnesium Oxide (18mg)

Getting enough of the mineral magnesium can support follicular health and hair growth. However, the dose here is quite low, and the oxide form isn’t very bioavailable, so this may not do much.

Zinc Citrate Dihydrate (5.5mg)

Zinc is a mineral with important roles related to immunity, hormone production, and antioxidant support, which all relate in some ways to having healthier hair. 

If you’re deficient in zinc, it appears you’re more likely to experience hair loss or hair thinning. 

Silica (26mg)

Silica is a trace mineral with a variety of potential benefits. It increases collagen production, decreases oxidative stress, and promotes hair follicle health, all of which could contribute to stronger, healthier hair. 

With these benefits in mind, it’s no surprise it’s used in other hair supplements too, such as Primal Harvest Hair Growth Complex

Eleuthero Root Extract (15mg)

The last ingredient in B40 Trufolix is eleuthero root, also known as Siberian ginseng. This root is mainly an adaptogenic herb used by individuals to reduce the effects of stress on the body. 

Due to its antioxidant and anti-inflammatory properties, it could also help with hair health. Yet, the dose in this formula is quite low, plus this claim doesn’t have much evidence even at higher doses. 

Does B40 Trufolix Work?

Overall, B40 Trufolix seems likely to promote hair growth and overall hair health. Of course, everyone is different, and it’s unlikely that everyone will see positive results. 

But it’s formulated with several well-researched ingredients, especially pretty much all of the ones in the TruFolix Complex. 

The other vitamins and minerals likely play key roles too, although they’re more beneficial in cases of deficiency.

One drawback to consider is that the TruFolix Complex is a proprietary blend, so we can’t know for sure how much of each ingredient is in there. This is pretty important since the dosage can determine overall effectiveness. 

But by and large, B40 Trufolix seems effective. And many users have noted positive benefits, with an average 4.5 out of 5 rating based on over 100 reviews. 

How Does B40 Trufolix Compare?

In general, B40 Trufolix is one of the better hair growth supplements because it contains a wide variety of evidence-based ingredients, including ones such as banana flower and lactobacillus plantarum that have been used in human clinical research (which is the best kind). 

Also, while we talked about the drawbacks of using proprietary blends, this is pretty common for hair growth supplements, so it’s not necessarily a down-grader.


One popular hair supplement that compares well to B40 Trufolix is Nutrafol. This formula has dozens of ingredients. This includes a variety of herbs and antioxidants such as curcumin, horsetail, and saw palmetto; vitamins and minerals including zinc and vitamin D; as well as collagen and other ingredients.

Overall, the Nutrafol formula is a bit more complex and versatile compared to B40 Trufolix, but it’s not necessarily better. It also has proprietary blends, just like B40 Trufolix so we don’t know the doses for several ingredients. 

Also, B40 Trufolix is priced considerably lower at $59 for 30 servings compared to $88 for Nutrafol. 

Vitauthority Radiant

If you’re looking for a more basic formula compared to the above two, then Vitauthority Radiant is a good choice. It has only five main ingredients, including zinc, iodine, and a research-backed compound called Keranat®.

Even though it’s more basic, Vitauthority Radiant is still well-formulated and proven to promote shiner, softer, and fuller hair. 

It’s also priced essentially the same as B40 Trufolix at $59.99 for 30 servings (with other options available).

Who is B40 Trufolix Best For?

B40 Trufolix is best for individuals looking to support all-around hair and scalp health. Specifically, it’s for those who want to boost hair growth, prevent hair loss, and keep the scalp and hair protected from inflammation and oxidative stress.
