vitauthority radiant review

There are many different hair growth supplements out there, but only a few are actually legitimate and effective. That’s why we want to make sure we go over every one that we come across to help you pick ones that actually give you that full, luxurious look.

And in this review, we’re taking a look at a hair supplement called Vitauthority Radiant to see if it’s one of the top ones or just another run-of-the-mill, lackluster hair product. 

In this Vitauthority Radiant review, we’ll cover the main ingredients, research and possible benefits, pricing, safety, and all other aspects to see if this is truly the right hair supplement for you!

About Vitauthority Radiant

Radiant is a hair growth support formula created by Vitauthority, which is a pretty popular wellness supplement company with many other products, such as Vitauthority Multi Collagen Burn, Vitauthority Detox Nourish, and Vitauthority Multi Collagen Protein

Vitauthority Radiant Hair Growth Support is featured by a trademarked ingredient called Keranat, which they say is clinically proven to promote healthier, stronger, fuller hair. This formula also has other synergistic ingredients such as vitamin C and hyaluronic acid to support overall hair health.

Another unique aspect of Vitauthority Radiant is the use of VidaSpheres, which is a trademarked clean-label, sustained-release technology. It’s designed to enhance ingredient stability and bioavailability, so you can get the most out of the ingredients. 

Oh, and the serving size is just one little capsule. Which makes Radiant very easy to take on a regular basis.

Vitauthority Radiant Benefits

Vitauthority Radiant is advertised to offer three main benefits for your hair:

  • Improved Hair Volume
  • Healthier Looking Hair
  • Support for Healthy Hair Growth
Vitauthority Radiant Benefits

Improved Hair Volume

Thinning hair can be an embarrassing and frustrating situation to deal with. And it only gets worse with age and added stress. 

But Vitauthority Radiant claims to improve hair volume so you can achieve that full head of hair you’ve always wanted (or prevent it from thinning if it’s already good!). Keranat is designed to promote hair growth factors which they say leads to increased hair density and fullness.

Healthier Looking Hair

Another hair problem people have is dullness or lack of vibrance. 

Radiant Hair Growth Support is advertised to give you healthier-looking hair, such as increased hair brightness and softness. This is due to a variety of natural ingredients such as vitamin C, hyaluronic acid, and Keranat, which may work together to reduce the effects of hair aging while promoting stronger, more resilient hair.

Support for Healthy Hair Growth

A number of factors can make hair growth much harder, such as stress, poor diet, and the aging process. Over time, these things can even lead to hair loss.

Vitauthority Radiant claims to offer critical hair growth support, mainly by using Keranat, which they say increases hair growth factors and supports hair follicle proliferation, leading to noticeable hair growth and fullness.

These are some great advertised benefits. But keep reading our Vitauthority Radiant review to see if this supplement actually works! 

Vitauthority Radiant Ingredients

Vitauthority Radiant is made up of five main ingredients, two of which are in their Hair Growth Support Blend.

Below are the Vitauthority Radiant ingredients:

  • Hair Growth Support Blend:
    • Keranat 
    • Hyaluronic Acid
  • Vitamin C
  • Iodine (from Seaceuticals Organic Kelp)
  • Zinc
Vitauthority Radiant Supplement Facts

Hair Growth Support Blend (350mg)

The most important part of Vitauthority Radiant’s formula is the Hair Growth Support Blend, which is made up or Keranat and hyaluronic acid. 


Keranat is a trademarked herbal blend of millet oil, sunflower oil, wheat grain extract, and rosemary leaf extract. 

This combination provides a mix of healthy fatty acids, antioxidants, minerals, and other compounds. 

Keranat has been shown to increase hair growth factors, enhance hair cell proliferation, and promote collagen thickness which allows for better hair anchoring. 

And in clinical studies, Keranat significantly decreased hair loss, reduced scalp dryness, and promoted shinier, softer, and brighter hair. 

Hyaluronic Acid

The other ingredient in this blend is hyaluronic acid, which is a natural compound found mainly in fluids in the eyes and joints. It has moisturizing effects, which may help to promote a healthier scalp. 

The moisturizing effects make it potentially useful for skin supplements too, such as HyaCera

In addition, some evidence shows that hyaluronic acid can protect cells involved in hair growth from damage, while also stimulating hair growth factors.

Vitamins and Minerals

Vitauthority Radiant also has vitamin C (50mg), zinc (10mg), and iodine (100mcg) for additional support.

Vitamin C has antioxidant effects and may help protect the hair from damage. Plus, it supports collagen synthesis and iron absorption, both of which are necessary for healthy hair.

Zinc is a trace mineral that also has antioxidant effects as well as various effects on hormones and other areas. People who are deficient in zinc may have hair loss issues, but supplementing doesn’t always seem to be effective.

Lastly, iodine is a trace mineral, which they obtained from Seaceuticals organic kelp. Just like with zinc, when you’re deficient in iodine you may have hair growth issues. 

Does Vitauthority Radiant Work?

Vitauthority Radiant definitely seems like it should work for hair growth and overall hair health.

The main ingredient, Keranat, is clinically studied to decrease hair loss and promote hair strength, health, and fullness. It’s also likely properly dosed too.

Keranat is in a blend weighing 350mg, with hyaluronic acid as the only other ingredient. And since the effective dose used in studies was 300mg, we can be confident that the dose of Keranat is very close to, if not at, this dosage. 

The other ingredients are all known to generally support hair growth and health too. But they probably won’t have as much of an effect. 

Claims vs. Reality

This product should work, but don’t expect to suddenly have the hair you once did 25 years ago or something like that. 

It’s likely that you’ll experience hair growth or at the very least, reduced hair loss. Not to mention improved hair shine, fullness, and softness. But these benefits will likely take at least a few weeks to develop, if not a few months for the biggest effects. 

Vitauthority Radiant For Healthy Hair

How Does Vitauthority Radiant Compare?

Vitauthority Radiant is at the top of the line for hair growth supplements mainly due to the use of a specific, clinically-studied hair growth ingredient (Keranat). But other aspects that make this product stand out are the proper dosing, third-party testing, supportive ingredients, and overall safe formula.

Another popular hair growth supplement is Nutrafol. This formula is more comprehensive as it includes over 20 ingredients, including various vitamins, minerals, herbal extracts, and other compounds. Some of the stars in Nutrafol that may promote hair growth, shine, and fullness are keratin, resveratrol, horsetail, collagen, and vitamin D. 

One of the issues is that many ingredients are grouped into proprietary blends. But overall it’s a quality formula. And it also has two different formulas for men and women. Nutrafol costs $88 for 30 servings which is quite a bit higher than Radiant which is at $59.99 for the same supply.

Another hair supplement that has a pretty complex formula is KeraNew. This is featured by a compound called Keraplast DFK Glow, which is a trademarked form of keratin. But there are many other ingredients in this formula for hair growth support too, such as collagen, hyaluronic acid, horsetail, burdock, vitamin D3, and iron. 

Overall, these ingredients can support hair growth and overall hair health. However, many ingredients are dosed pretty low. And all regular options for KeraNew cost well over $2 per serving although they do have discounted prices for new buyers.

Who is Vitauthority Radiant Best For?

Vitauthority Radiant Hair Growth Support is best for people who want to naturally support hair growth, shine, and fullness, while reducing the chance of hair loss down the line.

How to Take Vitauthority Radiant

Vitauthority Radiant comes in capsule form. The serving size is just one capsule. Take one capsule with water once per day, with or without food. 

Vitauthority Radiant How To Use

It’s best to supplement for at least 8 weeks.

Is Vitauthority Radiant Safe?

Vitauthority Radiant should be safe for most individuals as the ingredients are generally recognized as safe.

One thing to consider is the relatively high doses of zinc and iodine, which could lead to toxicity if you already consume a lot of these minerals in your diet. 

Other possible side effects are mild ones such as nausea, upset stomach, bloating, and headache.

Rarely, allergic reactions may occur.

Vitauthority takes a number of steps to ensure safety. Radiant is made in the USA in a cGMP, FDA-registered facility. It is third-party tested and lab-verified. And it is also plant-based, vegan-friendly, non-GMO, gluten-free, dairy-free, and free from artificial dyes.
