The Best Ashwagandha Capsules: Our Picks

Buying and evaluation criteria for Ashwagandha capsules

When buying Ashwagandha capsules, there are a few things you should consider. We have compiled the following evaluation criteria for you:

Criterion by criterion, we will now show you what is important and how you can sensibly assess the quality of Ashwagandha capsules.

Ingredients

Ashwagandha contains many effective nutrients. According to a study, ashwagandha leaves contain 62 plant substances, while the roots contain 48 plant substances. (1) Vitamins and minerals are hardly found in the ashwagandha plant. However, the following ingredients are valuable:

  • Withanolide
  • Alkaloids
  • Choline
  • Fatty acids
  • Amino acids

The effect of ashwagandha is based on the interaction of the individual plant substances.

Ideally, the withanolide content of an ashwagandha product is between 5 and 10 percent. If this value is not stated on the packaging, a lower value is to be expected.

The withanolide content in particular plays a decisive role. The higher the content, the better.

In addition to the withanolide content, you should make sure that no chemical additives have been added to the ashwagandha product. These can include superplasticisers, anti-caking agents and fillers. Therefore, make sure that you buy pure Ashwagandha without any additives.

Dosage

Capsules usually contain 300 to 500 milligrams of ashwagandha extract. You should not take more than two capsules a day. It is best to try one and see how it works. The onset of effect is individual and can take a few days or even several weeks.

In general, the dosage depends on your level of discomfort and the goal of the treatment. If you only have mild symptoms, an average dosage of 300 to 500 milligrams of ashwagandha extract, i.e. one capsule, is recommended daily. If you have severe symptoms, the dosage can be increased to 1000 to 1500 milligrams.

With a high dosage, however, you should read the package leaflet of your ashwagandha product very carefully and, if necessary, discuss the use with a specialist - pharmacist or doctor.

Although the body does not really have to get used to taking ashwagandha and does not build up any tolerance to it, side effects such as nausea or diarrhoea can occur in the case of an overdose.

This is another reason why one should not experiment with an excessive dose, because ashwagandha contains stimulating and intoxicating substances.

The ideal time to take an ashwagandha capsule is about one hour before a meal. Taking it shortly before a meal can lead to digestive problems due to water- and fat-soluble ingredients.

Those who want to take the capsule after a meal should allow two hours to pass. The capsules should be taken with plenty of liquid (1 large glass).

Cultivation

As with any agricultural product, cultivation has a great influence on its quality. This is no different with the Ashwagandha plant than with common vegetables and fruits. If you want the best quality free of synthetic chemical pesticides, you should buy organic ashwagandha products.

With the organic seal on the products, you can assume that it is a sustainable and organic product. Many ashwagandha products are indeed organically grown. This is a good thing because you take Ashwagandha daily over a long period of time.

Capsule shell

There are two types of ashwagandha capsule shells: vegetable and animal.

When choosing whether to use vegetable or animal capsules, the question is not which is better and which is worse. In fact, both are equivalent and have the same effect.

Animal capsule shells are made from gelatine. In other words, from the connective tissues of various animals. Animal capsule shells are widely available and therefore tend to be cheaper than the vegetable alternative.

Vegetable capsule shells are usually made of synthetically produced cellulose or starch. This is absolutely harmless to health. The only thing you have to make sure of when buying capsules is that they are enteric-coated. Otherwise they cannot develop their effect.

Vegetable capsule shells are therefore particularly suitable for people who follow a vegetarian or vegan diet and are not allowed or do not want to consume animal products for cultural, religious, ethical or other reasons.

Guide: Frequently asked questions about Ashwagandha capsules answered in detail

In order to inform you comprehensively about the effectiveness of Ashwagandha capsules and to give you an understanding of the current state of science, we have summarised all the important information in the following sections.

What is Ashwagandha?

Ashwagandha - better known in this country as winter cherry, sleeping berry or Indian ginseng - is a plant and belongs to the nightshade family. Ashwagandha is Sanskrit and means something like "horse smell". In fact, the ashwagandha root smells very intense and can have a strong effect.

Ashwagandha has long been used as a natural remedy in India, Pakistan and Afghanistan. Especially in Ayurvedic medicine, whitania somnifera is a very popular plant and is an important component of the Indian art of healing.

In the meantime, ashwagandha has also become a household name in the western world. It grows mainly in subtropical areas, including Greece, Spain, Sicily and the Canary Islands.

Ashwagandha is a herbaceous and bushy plant with green oval leaves and small orange-red berries. However, it is not the fruits that are used as a natural remedy, as the German name Schlafbeere suggests. It is the roots and leaves of ashwagandha that have a variety of properties.

How do Ashwagandha capsules work?

The Ayurvedic natural healing plant Ashwagandha works in many different ways in our body. A central effect of Ashwagandha is the lowering of cortisol levels. This lowers the stress level, which in turn has a positive effect on sleep and general performance.

However, ashwagandha does not only support the body in coping with stress. Studies also show that ashwagandha has other positive effects, including on fertility and sexuality. In this section we describe how Ashwagandha works exactly and what the natural herb is good for.

Ashwagandha against stress

Ashwagandha is one of the so-called adaptogens. These are medicinal plants that can help the organism to cope with stress. Taking ashwagandha capsules can therefore make you more stress-resistant.(4, 5)

Ashwagandha works against stress by lowering the level of the stress hormone cortisol. (3) Scientific studies speak of a significantly improved objective as well as subjective stress perception of the study participants.

Ashwagandha can therefore be a natural weapon against stress. After all, when stress persists, the cortisol level is chronically elevated, which can trigger a variety of health consequences such as insomnia, sensitivity to pain and depression.

Ashwagandha for insomnia and anxiety

Ashwagandha is also called sleep berry. This is undoubtedly an obvious indication of another mode of action of this Ayurvedic natural healing plant. It helps against sleep disorders, which has been scientifically confirmed several times.(5, 6, 7)

As ashwagandha has been proven to make people more stress-resistant, it improves the quality of sleep. (3) Among the study participants, insomnia decreased by a good 70 percent thanks to lowered cortisol levels.

According to the same clinical study, not only did insomnia decrease, but also anxiety. The anxiety-relieving effect was confirmed in further scientific studies.(5, 6, 8)

Male fertility and female sexuality

In connection with the intake of ashwagandha, an increase in testosterone levels was observed in men. (9)

In addition, ashwagandha appears to be a potent agent for male fertility. This is because it improves sperm quality in terms of production and motility (10) In women, ashwagandha is also said to trigger more sexual pleasure and less sexual frustration.

Brain performance and memory

Improved stress resistance thanks to ashwagandha does not only mean more calmness and better concentration. Studies show that ashwagandha actually has a positive influence on brain performance and memory.(12, 13)

Cognitive abilities improve significantly in terms of memory skills, reaction time, attention and speed of information processing.(12, 13)

Arthritis and joint pain

In Ayurvedic medicine, ashwagandha is also used to treat arthritis. The natural herb is said to relieve joint pain and swelling and improve mobility. Studies confirm this effect.(14, 15)

In the former, study participants with knee joint pain affirmed that their complaints were noticeably reduced through the administration of ashwagandha.

Schizophrenia and depression

A study with schizophrenia patients showed that the symptoms of schizophrenia improved significantly. (16) Anyone suffering from this mental illness could therefore benefit from taking ashwagandha. This is also a possibility for people with depression. Science confirms an alleviation of depressive symptoms.(3, 17)

Cholesterol and diabetes

Several scientific studies indicate that high-dose ashwagandha intake can lead to a significant improvement in blood lipid levels, thus lowering total cholesterol.(18)

Moreover, when treating type-2 diabetes with ashwagandha, the Ayurvedic medicinal plant has been found to have the same effect as anti-diabetic drugs.(19)

Endurance and muscle building

Ashwagandha is also said to enhance performance during sports activities. Various studies point to an improved endurance capacity and stronger fat burning. The intake of ashwagandha also has a positive effect on strength and muscle building.(18, 20)

Anti-aging effect

Taking ashwagandha lowers the cortisol level. At the same time, the DHEA level increases. DHEA is an anti-stress and anti-aging hormone and is considered to be the antagonist of cortisol: if one increases, the other decreases. So if you have a healthy DHEA level, you are not only more stress-resistant, but also enjoy an anti-ageing effect.(4)

When and how often should Ashwagandha capsules be taken?

Capsules contain an average of 300 to 500 milligrams of ashwagandha extract. You should take one, maybe two capsules a day. Be sure to read the package leaflet carefully. However, if the level of suffering is very high, you may take three capsules a day in consultation with your doctor.

However, a daily dosage of more than 1500 milligrams is not recommended, as high doses of ashwagandha can cause undesirable side effects. These can include nausea or diarrhoea. This is another reason why one should not experiment with an excessive dose, because ashwagandha contains stimulating and intoxicating substances.

The ideal time to take an ashwagandha capsule is about one hour before a meal. Taking it shortly before a meal can lead to digestive problems due to water- and fat-soluble ingredients.

Those who want to take the capsule after a meal should allow two hours to pass. The capsules should be taken with plenty of liquid (1 large glass).

It is also recommended to take the capsules at the same times each day. For example, take one capsule in the morning and one in the evening. You will have to experiment a little with this. Depending on when you experience the effect, the optimal time for you to take the capsules will be different.

Who should not take Ashwagandha capsules?

Although Ashwagandha is a natural remedy, there are groups of people who should clarify the intake of Ashwagandha with a specialist beforehand.

For example, people with high blood pressure, diabetes(2) and thyroid dysfunction, as well as people with mental and autoimmune diseases, are advised to discuss the intake of Ashwagandha with a doctor.

Consultation with a doctor is also advisable if you are already taking other medications. Certain drug combinations can lead to undesirable side effects, which you naturally want to avoid.

Due to a lack of scientific research and findings, pregnant and breastfeeding women are also advised not to take ashwagandha. (2) Likewise, parents should not give ashwagandha products to their children who are under 12 years of age. The same applies to people who have an irritated or generally sensitive stomach.

When does the effect of an Ashwagandha capsule begin?

When the effect of Ashwagandha capsules sets in varies from person to person. Sometimes it only takes a few days before you feel the effect of the natural remedy. But it can also take a few weeks before it becomes noticeable.

Are Ashwagandha capsules healthy? Are there any side effects?

Ashwagandha is considered a natural herb in Ayurvedic medicine. Taking Ashwagandha capsules in the recommended amounts is absolutely safe. Side effects usually only occur in case of an overdose.

When complaints do occur, they are digestive complaints such as abdominal pain and diarrhoea, often accompanied by nausea. In some cases, taking too much ashwagandha can cause (severe) headaches.

Too much ashwagandha can also have a stimulating and intoxicating effect. If side effects occur, the dosage should be adjusted or ashwagandha should not be taken for a while.

What types of Ashwagandha capsules are there?

There are two types of Ashwagandha capsules: herbal and animal. The main distinguishing feature is the nature of the capsule shell.

Type Description
Vegetable Ashwagandha Capsules Vegetable capsule shells are usually made of synthetically produced cellulose or starch. This is absolutely harmless to health. The only thing you have to make sure of when buying the capsules is that they are enteric-coated. Otherwise they cannot develop their effect.
Animal ashwagandha capsules Animal capsule shells are made from gelatine. That is, from the connective tissues of various animals. Animal capsule shells are widely available and therefore tend to be cheaper than the herbal alternative.

With plant or animal ashwagandha capsules, the question is not which is better and which is worse. In fact, both are equivalent and have the same effect.

Vegetable capsule shells are particularly suitable for people who follow a vegetarian or vegan diet and are not allowed or do not want to consume animal products for cultural, religious, ethical or other reasons.

How much do Ashwagandha capsules cost?

Ashwagandha capsules do not cost the earth. Capsules with a vegetable coating are slightly more expensive than those with an animal coating. However, the difference is not very significant, as the table shows.

We have compared the prices for you and give you a price range for both types.

Type price range
Ashwagandha capsule with vegetable coating approx. 15 to 25 GBP
Ashwagandha capsules with animal coating approx. 8 to 15 GBP

Organic capsules are also usually a bit more expensive than those that do not meet organic standards. The same applies to capsules that are lactose- and gluten-free.

Besides the type, the price differences are also mainly due to the size of the packaging. Some packages hold 100 capsules, others over 180 to 240, for example.

What alternatives are there to Ashwagandha capsules?

Ashwagandha is available in different dosage forms. The advantage of capsules is that they are neutral in taste and the dosage is fixed and therefore easy to follow.

However, if you don't like swallowing capsules and don't mind the bitter taste of ashwagandha, you can try the following alternatives:

Alternative Description
Root If you want to use ashwagandha in its unprocessed form rather than just the extract, you can use the root. For example, you can use the root for an ashwagandha tea. However, as ashwagandha has a bitter taste, this form of administration takes some getting used to.
Powder Ashwagandha powder also has a bitter taste, but is suitable for various forms of preparation. You can also use the powder for a tea, mix it into muesli or add it to a smoothie.
Oil Ashwagandha is also available as an oil extract. You can take the desired amount directly on the tongue or mix it into a drink or food.

Do Ashwagandha capsules help with weight loss?

Ashwagandha capsules as a food supplement can directly and indirectly help you lose weight. In fact, Ashwagandha has a positive effect on your cholesterol level and also helps you with sports activities.

It not only increases your endurance and strength and muscle building, but also improves your fat burning.

In addition, thanks to ashwagandha you have a calmer and better sleep, as it supports you in coping with stress and makes you more resistant to it. This also has a positive effect on your condition and indirectly helps you lose weight.
