For over ten years, we have been committed to empowering women with the tools and knowledge they need to take control of their bodies, fertility, and health-related issues.
Our founder, Helen Denise, had a thriving career in the early 1990s, but an unexpected event set her on a new path.
Helen experienced an ectopic pregnancy in 1999, a challenging and traumatic ordeal that brought excruciating pain.
But this experience also wrought a clear transformation in Helen, as it had forced her look at things with new eyes.
Surviving this life-altering experience, she left the hospital with a new purpose in life and resolved to support other women in understanding their fertility and bodies.
Helen Denise is all about women’s health. Whether as a company founder, fertility advocate, author, speaker, actor, award-winner and entrepreneur, she has spent the past 25 years on a singular mission to give women trying to conceive or searching for a natural family planning solution the best tools to understand their unique fertility cycles.
Helen’s passion was born out of a near-death experience from an unplanned ectopic pregnancy and a desire to better understand her body. She put her research-based knowledge and experience to work to invent a saliva-based ovulation test with 98.9% accuracy to identify a woman’s 5 (five) most fertile days in her cycle. She has helped millions of women conceive and manage their fertility.
Since 2009, Helen Denise has served as the Founder and CEO of HiLin Life Products, Inc., maker of the next- generation, U.S. clinically tested and FDA cleared KNOWHEN® Advanced Saliva Ovulation Test and Fertility Monitor App. The company originated the Saliva Ovulation Test category in the U.S. and is the leading saliva ovulation test worldwide. The award winning product has been featured in TIME, Fox News, The Wall Street Journal, FORBES, Star Ledger, Chicago Tribune, Disney, Yahoo and many other publications. Denise regularly blogs about issues affecting women’s health.
Prior to her work with HiLin Life Products, Helen served in leadership roles for seven years at Swiss international consumer goods enterprise. In 1995, Helen left the comfort of a successful career, her family and Russian culture to embrace the challenge and risk to relocate to the USA as National Sales Director of Swiss company. She learned that with risks come great rewards. Helen Denise successfully led a sales team of 500+ professionals and quickly grew her North American territory from zero to $20 million in sales. She also produced more than 100 TV shows in three years as the TV program manager, spokesperson and editor.
Denise fundamentally believes women should not set boundaries for their dreams, but instead let belief, hope and love drive their journeys through life. And above all, never give up.

Excellent product! I am using it along with the Billings ovulation method and it is just a perfect combination for me since the Billings method tells me my fertile days and this one not only knows when I am fertile but also when I am ovulating!
The KNOWHEN® saliva test has been a fantastic addition in our quest for pregnancy. It is so empowering to have a visual component to see your own hormone changes and predict fertility. It is so much cleaner to use and less wasteful than the plastic monitors and plastic urine sticks.
This product empowers women to have reliable information regarding their fertility. Knowledge is power and this gives reliable information to all who use it. I give it to my family and friends who want to know when they are fertile to conceive and those who want a non-invasive and drug-free form of birth control.
The KNOWHEN® Ovulation Test tracks your ovulation using only a drop of your saliva. It identifies your five (5) most fertile days and the best days in your ovulation cycle if you’re trying to conceive.
