What is “Kin Dock”?
A gut DNA test kit for those who want to understand their true self, take proper gut care, and improve health management.
Know your gut, know yourself, know your future.
Recent research has shown that the gut is connected to every aspect of beauty, health, and mental well-being.
However, no two people have the same gut environment.
That’s why understanding your own gut through DNA testing helps guide your personal beauty and health care, serving as a key to achieving the results and future you desire.
Intestinal DNA testing
Your intestinal "personality" emerges
Gut DNA testing analyzes the genes of gut bacteria from your stool, providing detailed insight into which bacteria—and how many—are present.
Kin Dock stands out with twice the accuracy of traditional tests, identifying bacteria down to the species level.
It reveals your unique gut environment that typical tests might miss.
Moreover, it shows whether specific bacteria like Lactobacillus gasseri or Lactobacillus reuteri—often found in yogurts—are present in your gut, helping you choose foods that suit your body.
Understanding your gut is the first step to better health.
It’s a reliable starting point to begin personalized gut care and improve your diet.
The Secret Behind Kin Dock’s Popularity
Knowing the exact bacterial species gives you helpful shopping tips.
Most gut tests only analyze bacteria at the genus level. But Kin Dock goes deeper, identifying bacteria down to the species level.
This means you get a more accurate picture of which bacteria—and how many—live in your gut.
Plus, it checks compatibility with bacteria found in store-bought yogurts and fermented foods, helping you choose the best products for you at the supermarket.
Your personalized gut report, easy to understand with clear graphs.
You’ll receive an easy-to-understand report with graphs and tables showing your gut age, type, diversity score, and bacterial distribution.
Especially, it clearly shows the proportions of key gut bacteria, helping you and your family understand your body’s tendencies and improve diet and lifestyle habits.
A trusted test kit chosen by hospitals and clinics for peace of mind.
Kin Dock is a professional gut test used in medical facilities and beauty clinics.
It offers high accuracy while being easy to use at home, with clear results. Trusted by experts and designed for everyday users, this balance makes it so popular.
User feedback
Male in his 30s
(Office worker who mainly works from home)
I had been feeling bloated and sleepy for some reason. The results of a bacterial checkup showed that I had low diversity in my intestines and a lack of good bacteria. I reviewed the contents of my breakfast and started to consciously eat fermented foods and vegetables, which improved my concentration during the day and stabilized my physical condition. I feel like I've finally gotten over the "vague feeling of being unwell."
40's female
(Juggling housework and work)
I thought my rough skin was caused by stress, but I was surprised to learn from a bacterial checkup that my intestinal balance was out of whack. By being mindful of my intestines and incorporating fermented foods into my daily meals and cutting out snacks, I was able to see positive changes in both my skin condition and my mood. I've come to realize the importance of taking care of yourself from the inside out.
Female in her 50s
(Beauty salon management)
While I care about my customers' health, I tend to put my own health problems on the back burner. Recently, I was worried about constipation and fatigue, so I underwent a bacterial checkup and found out that I had extremely low levels of butyric acid bacteria. I started consciously eating warm vegetables and dietary fiber for breakfast, which helped my intestines to be in good condition and made me feel much more comfortable during the day. Being able to objectively know the state of my body is a great help in self-management.
