How to do a safe gut cleanse at home


The gut is not just a significant part of the digestive system. Up to 80% of our immune system is also located in the gut. Tens of trillions of bacteria that inhabit the colon are involved in the processes of metabolism and the removal of toxins from the body. Basically, your body is a personal detox machine and regularly performs a gut cleanse by itself.

Another interesting fact: we share about one third of the gut microbiota with other people. The other two thirds are particular to you only. In other words, your microbiota, just like fingerprints, makes you unique.

Beneficial gut flora is is located mainly in the large intestine. The total mass of microbial flora here can go up to 1,5 – 2 (!!) kilograms. There are all kinds of bacteria there – both good and potentially pathogenic, (i.e. dangerous given the right circumstance).

This implies that the danger does not appear from mere presence of pathogenic flora, but from the imbalance of bad / good bacteria.

“All disease begins in the gut”

– Hippocrates


Taking medicine (in particular, antibiotics), infectious diseases, stress, dietary habits and lifestyle can lead to an imbalance of gut flora and can result in digestive disorders, skin issues and impaired immunity.

One way of restoring a healthy balance of gut flora is the so-called cleanse, or detoxification.


During spring, many people start to experience discomfort in the gut. This can show up as bloating, heaviness after eating, intolerance of certain food. One of the reasons is the residue that forms on the inner surface of the gut. It is comprised of food particles and other waste products.

The inner surface of the small intestine looks like a set of fibres or “tentacles” responsible for the processing and absorption of nutrients from food. This helps to significantly increase the total area of absorption.

Flaxseed is a must-have item in your kitchen cabinet. It is an excellent source of three types of valuable polyunsaturated fatty acids: Omega-3, Omega-6 and Omega-9. These need to be balanced in order for organs to function properly. If you are taking fish oil as a supplement, you can safely remove it for the duration of this gut cleanse, along with any vitamins – you definitely won’t need them for 21 days!

Flaxseed is also great source of vitamins A, E, B, and selenium. Selenium is known for its antioxidant components and, together with vitamin E, it protects the body from free radicals. Selenium is vital for the synthesis of thyroid hormones that regulate the body’s metabolism and protects against heart diseases. Flaxseed is rich in potassium (7 times more than bananas). It is also and excellent source of fibre (both soluble and insoluble) which acts as a brush and helps to literally scrape out the inside walls of your over-worked intestines.

To help with absorption, it is best to grind the seeds.


  1. Take a topped teaspoon (about 5 grams) of ground flaxseed;
  2. Mix the seeds with Greek yogurt, kefir or other vegan yogurt (if you have lactose intolerance);
  3. Put in the refrigerator overnight;
  4. Drink this mix on an empty stomach (a glass of water is allowed) first thing in the morning);
  5. After 40 minutes, your stomach is ready for breakfast!


By the end of day 3 you will start to notice the difference. Try to stick to the cleanse for three weeks (21 days) to give your gut a thorough reset. To save time, make several servings of such yogurt and keep refrigerated for up to 3 days.
