Most of us can picture large herds of cows grazing in beautiful clover fields when summer in Denmark is at its peak. But while cows can break down plants thanks to their four stomachs and absorb their nutrients, humans need a little more help to benefit from the active compounds and positive properties of red clover.
The fermentation process
One way of doing this is fermentation. When red clover is fermented, the plants are essentially fermented using lactic acid bacteria. The process begins by harvesting fresh red clover, pressing out the juice, and transferring it into large tanks.
Here, the red clover is mixed with a culture containing lactic acid bacteria, which initiates fermentation. This process makes it easier for humans to absorb the active compounds in red clover.
The fermentation process opens the plant cell walls, allowing the active substances to be released. At the same time, the lactic acid bacteria — together with those naturally present in the human body — help transport these compounds across the intestinal wall into the bloodstream.
You can find out much more about the actual fermentation process and how it impacts the plant agents, vitamins and minerals, in our article titled “What is fermentation?”, which you can find here.
Benefits of fermentation
The advantage of fermented red clover is that not only are its active compounds more easily absorbed, but so are nutrients from the rest of your diet — such as vitamins, minerals, fats, and other plant compounds.This may help you gain more benefit from nutrients and support overall health. Fermentation preserves the natural qualities of food and may enhance the effectiveness of plant compounds once they reach the intestines.
Different types of fermentation
There are many different forms of fermentation. In fact, many everyday foods are the result of fermentation, including wine, cheese, yoghurt, bread, beer, and even chocolate.
Did you know you can also ferment foods at home? It is not as complicated as it sounds. If you need inspiration, we have created a recipe for fermented carrots, which you can find here.
Benefits of fermented red clover extract
So how exactly can fermented red clover extract benefit your health? It has been known for many years that red clover can help with the discomfort that many women experience during the menopause. The most well-known symptoms of the menopause are probably hot flushes and sweats. Many women experience these both during the night and during the day, which can be very disruptive to quality of life. A number of other symptoms are also associated with the menopause. Some women experience fatigue, worse sleep, mood swings, bleeding disorders and sluggish digestion.
Why do you experience symptoms during the menopause?
For most women, menopause occurs around the age of 51–52, marking the final menstrual period. The severity, frequency, and duration of symptoms vary greatly from woman to woman. Some experience menopause as a short phase, while others may experience symptoms for many years.
Menopause occurs because the ovarian reserve is depleted, leading to a decline in oestrogen and progesterone levels. These low hormone levels, and the resulting imbalance, trigger many of the characteristic menopausal symptoms.
Fermented red clover extract with herbs
Red clover cannot take all the credit for helping to alleviate all the symptoms that many women experience as they go through the menopause. This is why our fermented red clover extract also contains a number of other herbs that can help to ease the menopause. Red clover is best known for its ability to reduce hot flushes and increased perspiration. It can also help to reduce the experience of feeling restless.
Lemon balm and a positive mood
As already mentioned, we have added other herbs to ensure that our fermented red clover extract has the greatest possible benefits for menopausal women. The herbs are familiar to most kitchen gardens and are also cultivated on the land around our farm. First of all, we have added the herb lemon balm, which helps to maintain a positive mood, normal sleep and mental and physical well-being.
Peppermint and digestion
Digestion is often overlooked during menopause, but it can also be affected. For this reason, peppermint is included in our fermented red clover extract, as it supports normal digestive function and may help relieve sluggish digestion.
Sage and its benefits
Finally, sage is included. Sage contributes to normal sweating function and helps maintain joint flexibility and mobility in menopausal women. Just like red clover is processed into an extract, the added herbs also undergo transformation from fresh plants into fermented extracts.
Does fermented red clover have side-effects?
When discussing the benefits of red clover, it is natural to ask whether it has side effects.
In healthy individuals with no underlying conditions, there are no known or documented side effects associated with either red clover or fermented red clover extract. The reason side effects are discussed at all is that red clover naturally contains phyto-oestrogens. These are not added hormones but naturally occurring plant compounds.
Safety and EFSA Assessment
In 2015, the European Food Safety Authority (EFSA) conducted a major safety assessment of red clover and phyto-oestrogens. It concluded that there is no increased risk for healthy women consuming up to 150 mg of phyto-oestrogens daily.
For comparison, REGOMEO from Herrens Mark contains 67 mg per 120 ml.

Phytoestrogens in red clover
Phyto-oestrogens are also known as isoflavones. They are found not only in red clover but also in foods such as soya.
These compounds are the reason red clover may help alleviate menopausal symptoms. When oestrogen levels decline during menopause, phyto-oestrogens may help restore balance.
Hormonal imbalance during menopause can lead to hot flushes, low energy, sluggish digestion, and poor sleep quality. Red clover, containing phyto-oestrogens, may therefore support a calmer and more comfortable menopause.
Can you get fermented red clover in tablets?
The short answer is no. It is not possible to produce fermented red clover in tablet form.
The lactic acid bacteria used in fermentation cannot survive freeze-drying in sufficient quantities for tablet production. Additionally, achieving the same level of active compounds would require a very large number of tablets per day compared with a liquid extract.
The live bacteria also help preserve the extract, which is why Herrens Mark’s products are patented and unique. The extracts are unpasteurised and contain no additives, made possible by a naturally acidic pH of around 4, which allows only beneficial bacteria to thrive.
Can you get fermented red clover in capsules?
The taste of fermented red clover extract can be challenging for some people, as it is slightly bitter and sour. However, this is something most people adapt to over time. Alternatively, it can be mixed into juice, smoothies, or sparkling water with citrus flavour.
This taste profile is one reason people ask for capsules or tablets. However, as with tablets, it is not possible to replicate the benefits of fermentation in capsule form. Non-fermented red clover supplements in tablet or capsule form do exist, but it is important to note that they do not contain the fermented extract. Without fermentation, absorption of the active compounds is reduced.
Fermented red clover from Herrens Mark
What makes Herrens Mark REGOMEO and REGOBONE fermented red clover extracts unique is that, unlike many other red clover products, they are fermented. The fermentation process itself is patented. We patented this process because fermentation breaks the phytoestrogens down into smaller units that are more absorbable.
Fermentation in brief
Fermentation splits the sugar molecules from phyto-oestrogens. Once this occurs, the active compounds are more easily absorbed because they can pass through the intestinal wall in the small intestine. Lactic acid bacteria consume much of the sugar molecules, leaving phyto-oestrogens in a form ready for absorption.
Menopause and Bone Health
Fermented red clover is not only relevant for menopausal symptoms. Declining oestrogen levels also affect bone density in women.
Calcium and vitamin D help reduce bone mineral loss in postmenopausal women. Low bone mineral density is a risk factor for fractures due to osteoporosis.
A daily intake (from all sources) of at least 1,200 mg calcium and 20 μg vitamin D is required to reduce bone mineral loss.
For individuals needing to maintain bone health, the Danish Veterinary and Food Administration recommends 800–1,000 mg calcium and 20 μg vitamin D daily.
Bone Loss
The menopause and bones
Osteoblasts, the cells responsible for bone formation, are stimulated by oestrogen.
REGOBONE from Herrens Mark contains calcium, magnesium, and phyto-oestrogens from red clover, making it relevant for women with low bone mineral density and postmenopausal women experiencing natural bone loss due to declining oestrogen levels.
