Frequent Questions, Better Answers
Radiant may improve overall hair growth, but it's not area specific. However, the scalp is a lot more sensitive to environmental factors which aligns with Radiant's focus and effects on a healthy scalp.
It's best to take both together, especially if you're looking for the hair benefits! Radiant Hair Growth Support improves collagen synthesis as it's formulated to increase your hair’s collagen thickness to reduce shedding
Like with most supplements, hair will start to go back to the health that it was in once you stop supplementation. While it will not be immediate, it is important to ensure you keep offering your hair the best environment to thrive.

Take back your confidence in your hair thanks to a scientifically rounded blend of key clinically researched ingredients that have been shown to promote hair growth^, support hair vibrancy, and increase hair volume with just 1 capsule a day!


Our Hair Is Precious

And seemingly EVERYTHING is working against us keeping a healthy full head of hair as we age. Aging, hormonal imbalance, and stress are the 3 biggest culprits when it comes to us either losing our hair, losing fullness, or that natural shine our hair used to emit.

Promoting Hair Health at the Source

Vitauthority’s Radiant features a key clinically researched ingredient to create a complete formula designed to increase hair density, support healthy, softer hair, and increase your hair’s collagen thickness to reduce shedding.*


Zinc is an essential ingredient in the protein our body uses to build hair.*

Hyaluronic Acid

Hyaluronic acid supports moisture retention, which aids overall skin & hair health.*


Iodine also has strong antiparasitic, antibacterial, and antiviral properties that support scalp health.*

Vitamin C

Vitamin C helps build collagen, which is highly important for hair growth.*

Radiant Features Patented Ingredient:

1. Promoting Hair Growth:

Growth factors on the scalp may have a crucial role in the growth and development of hair follicles. They promote hair growth by increasing proliferation of keratinocytes, which can lead to an increase in hair growth. Keranat™ has also been shown to increase collagen thickness, which helps create an optimal environment for healthy hair growth.

2. Improve Hair Volume

By promoting healthy growth factors within the bulb and supporting collagen thickness, Keranat™ has also been shown to help reduce the rate at which we lose our hair in the telogen phase. After a 3 month trial, Keranat™ users lost 50% less hair when compared to a control group and saw overall hair density increase.^

Three Powerful Benefits

Improve Hair Volume*

By promoting healthy growth factors within the bulb and supporting collagen thickness, we can help reduce the rate at which we lose our hair. After a 3 month trial, 91% of Keranat users observed a decrease of hair loss. Keranat also has been shown to improve hair density and volume, leading to a fuller looking head of hair.*

Promote Healthier Looking Hair*

75% of Keranat™ subjects noticed an improvement in hair brightness and softness.*

Support Healthy Hair Growth*

With Keranat™, significant cell proliferation (necessary for hair growth) has been observed on the cells of the hair bulb. The increase in growth factors seen with Keranat™ help stimulate keratinocytes, guide the hair follicle development and are responsible of hair bulb matrix formation, and control hair cycle.*

Amazing Ingredients Mixed With Amazing Technology

Radiant also utilizes VidaSpheres™, a clean-label, sustained-release technology. Not only do VidaSpheres™ look awesome (seriously, they're pretty damn cool), but they also provide functional benefits, such as increased ingredient stability and bioavailability through slow-release technology. Additionally, the protective outer layer reduces exposure to light, temperature, and other environmental factors.

    Happy with my results!

    I started taking the Radiant Hair Growth Support supplement about a year ago. I ended up with Covid pretty bad in September of 2021. After Covid, my hair started falling out and breaking off. I lost about 40% of my hair. I ended up getting extensions in February 2022 to help my hair recover. I removed them in September of 2022. My hair was less damaged, but it still was not growing. It was thin and shedding. In February 2023, I started taking the Radiant Hair Growth Support, along with one other supplement (I had been taking the other supplement while I was trying to get my hair to recover, and it wasn't enough) in February 2023, and a year later, my hair is longer, thicker, and shedding a little less. It takes a few months to kick in, and I now take it every day. So you need to keep taking it. But it is worth it!

    The absolute best!

    Sometimes, the way to tell if something is working is to not take it for a while. So I did that with the Radiant. After about a week, my hair started becoming duller and falling out more. After a month, I couldnt stand it and restarted. Just last week , i went to get my hair cut. My stylist could not believe not only how fast my hair grew in 2 months, but how thick it was and how shiny. I told her about Radiant. Im pretty sure she is placing an order and she tells others about it.

    Starting to feel a difference

    I'm losing less hair when I brush and in the shower. It's also starting to grow faster. I'm really happy with the results after 2 months of daily use. My only complaint is the capsules are greasy.

    Really works, noticeable difference!

    I work for the company that owns Vitauthority. I have been on Radiant for 3 months and stopped using it for a month. After a few weeks of not taking the product, I noticed more hair on the bathroom floor and sink in the morning so I immediately ordered more and paid full price for it. I ordered two more bottles recently to keep my supply going. I think it was worth it, so worth it, that I paid the full price for product without an employee discount! My hair definitely sheds less, looks healthier/softer, and is stronger when I am on Radiant. I am growing my hair from a pixie cut and taking this has definitely helped. I wear my hair short because it is fine and gets stringy when it reaches chin length, but this product, combined with my daily dose of Collagen Burn have made a real difference in how fast and how thick /strong my hair has become!
