Fruit for a Fertile Gut

Fruit for a Fertile Gut

Micronutrients play a vital role in our fertility. How can you make vitamins and minerals more bioavailable?

Nurture your microbiome!

The bacteria living in your gut influence the release of minerals from the food we eat. They also help us absorb these minerals and vitamins from our gastrointestinal tract.

With a healthy microbiome, micronutrients have better bioavailability and bioaccessibility.

We get thiamine, folate, biotin, riboflavin, and panthothenic acid from our diet, but they are also made by our gut bacteria. It is estimated that up to half of our required daily Vitamin K is provided by our gut friends.

With a healthy gut microbiome the absorption of calcium, zinc, magnesium and selenium is also improved.

Here are three of our favourite prebiotic fruits to nurture the diversity of your gut microbiome!


Kiwi Fruit


After only a few days of including Kiwi fruit in your diet you will be promoting the growth of beneficial intestinal lactobacilli and bifidobacterial [1]. 

Kiwi fruit has stronger anti-oxidant effects than orange and grapefruit, and also contains 2 to 3 times the vitamin C fruit found in an orange [2]!


Vitamin C contributes to collagen formation for skin function [3] and promotes beneficial anti-inflammatory shifts in the gut microbiome [4]. The polyphenol extracts in kiwi fruit also reduce intestinal permeability [5] which supports fertility.


As a bonus kiwi fruit improves intestinal transit time, contains enzymes that support protein digestion and also delivers potassium, vitamin E and folate.



Not only is watermelon super hydrating, it also contains lycopene. Lycopene gives watermelon its red pigment and has prebiotic properties, increasing the abundance of beneficial Bifidobacterium in the gut [6].

Fertile Gut Watermelon Prebiotic

If you are game enough to eat the peel of the watermelon you can get even more prebiotic goodness! [7]

Watermelon contains coumarins, lignans, and flavonoids with anti-inflammatory, antioxidant, and anti-allergic activities. You can definitely add watermelon to your list of gut friendly foods.







Blueberries are packed with polyphenols. The foundation for a fertile gut is the production of diverse metabolites by our gut microbiota when they break down prebiotic compounds and polyphenols.

These beneficial metabolites include our reproductive health loving short-chain fatty acids, indole derivatives and polyamines that continually help to:

  • 🌱 Dampen inflammation
  • 🌱 Promote the growth of beneficial microbes
  • 🌱 Strengthen the intestinal barrier
  • 🌱 Optimise immune function
  • 🌱 Increase butyrate production


Bioactive polyphenols in  blueberries change the composition of our gut microbes so they can positively regulate inflammation, metabolism and hormone balance.

As gut microbes transform the polyphenols we eat, their bioavailability is increased generating even more fertility loving metabolites!

Polyphenols are effective in reducing endometrial lesion growth, dampening menstrual pain, and lowering androgen concentrations in PCOS.

Prebiotic Packed Fertile Gut Goodness

Our gut microbiota are vital for the conversion of the beneficial dietary flavonoids. With a diverse, healthy gut we have a greater chance of making flavonoids from fruit more bioavailable and bioactive to enjoy all their fertility-promoting properties!

Our whole of plant proven prebiotics in Fertile Gut Microbiome Essentials also delivers polyphenol goodness, including flavonoids and phenolic acids. This is in combination with the same fibre content of 166-300 g of fruit or vegetables!
