Karlijn Visser is the founder of Holistik.nl - an online lifestyle magazine for "the stylish and sustainable".

Tell us a little about yourself?

I'm 31 and an entrepreneur in the truest sense of the word. I used to be a co-owner of Friend of the Brand, formerly known as Goodiebag Girl. In addition to these companies, I have worked in several magazines as a lifestyle journalist, and I completed my media & culture studies at the University of Amsterdam.

In April 2015, together with my best friend and business partner Evelyn van Hasselt, I decided to start a company that was closer to my heart. It became Holistik, an online magazine for stylish and sustainable do-gooders. Why? Because to live fully it requires courage. For all brave souls, Holistics is 'A guide to the greater you'. Growing as a person often hurts. But what you get in return is a fulfilling life based on your full potential, and that's what Holistik is about.

What is your approach to a healthy lifestyle?

The supplements from VITAVIVA fit the lifestyle I stand for. To help people stand in their purest power with the support of natural supplements.

Is VITAVIVA different from other supplements you have taken?

It's actually difficult to say… I like the design of the Vitaviva products and the supplements are pretty high in quality and daily dosage. It feels very good to use them!

Do you have a mantra that you swear by?

"In life you get what you have the courage to ask for." This is one of my favorite quotes from Oprah. It helps me get down to earth and not be shy about asking for what I really need.

What are your favorite VITAVIVA products and why?

Organic Coconut Oil: a multifunctional product that I also use on my skin when I have pimples or some redness.

Multivitamin Vitamax: beautiful base supplement for use in combination with pure eating.

If you could only choose one VITAVIVA product, what would it be?

Absolutely the 15-Day Cleanse! Twice a year I do a detox with the 15-Days Cleanse. I like the natural and soothing way to cleanse, recommended by VITAVIVA. So my body and mind are not completely stressed due to a lack of energy. After 15-Day Cleanse, I use the Maintenance Cleanse to help my intestines build up the flora.

  2. 15 Day Cleanse Gut cleanse / 30 capsules


    15 Day Cleanse is a maximum strength formula containing several natural and effective laxatives such as senna leaves, cascara sagrada, psyllium husks, l.acidophilus, aloe vera, flaxseed and more.


    Natural laxatives are foods or herbs that contribute you to cleanse your gut. Natural laxatives work in different ways. They can be divided into the following categories: Stimulant laxatives, Mechanical laxatives and Osmotic laxatives. 

    Stimulant laxatives are called cleansers that are considered stimulants because they function on the intestinal muscles and have certain components that also affect the colon to stimulate bowel movements. They also work on your intestinal walls and increase the production of minerals and fluids and decrease the ability of the intestines to absorb sodium and chlorine. Mechanical laxatives are fibre-rich laxatives that add volume to your stools, retain water and moisturize the intestinal walls, and help in the most natural way to promote bowel muscle movements to help you go to the bathroom. These include soluble and insoluble fibres.


    15 Day Cleanse can be used occasionally or as a 15 day cleansing program. We always advise you to follow up a cleanse with Maintenance Cleanse for the best result.


    We always recommend that you read the following guide before you start the cleanse: HOW TO CLEANSE?


    We get a lot of questions about; "Which cleanse should I choose - 7 or 15 Day Cleanse?" The purpose of the products is nearly the same - to cleanse your gut effectively. However, the intensity is different. We always recommend the 15 Day Cleanse, if it is the first time you are cleansing. The 7 Day Cleanse is more intense, as it has to do the same job as 15 Day Cleanse, but in half the time. If you have already done a 15 Day Cleanse, then you and your gut are familiar with the program and next time you can try the 7 Day Cleanse.
