"Adaptogen" is one of those wellness words you see everywhere now, on ashwagandha, rhodiola, ginseng and more. But what does it actually mean? This guide explains the concept clearly and honestly, as a category and a history, without overstating what these plants can do.
Important context: "adaptogen" is a traditional and informal classification, not a regulated health claim. None of the plants commonly called adaptogens carry authorised UK health claims for "stress" or "adaptation." This article explains the idea and the heritage, not proven health effects.
Where the word comes from
The term "adaptogen" was coined by Soviet scientists in the mid-20th century to describe certain plants thought to help the body "adapt" to various stressors. It was a research concept and a classification, and over the decades it has passed into popular wellness language. It is useful to know that it began as a proposed category rather than a regulated or universally agreed scientific definition.
What plants are usually called adaptogens?
The plants most often grouped under this heading include ashwagandha (Withania somnifera), rhodiola (Rhodiola rosea), Panax ginseng, eleuthero (Siberian ginseng) and a handful of others. What they tend to have in common is a long history of traditional use in systems like Ayurveda and traditional Chinese medicine, often associated with vitality and resilience in those traditions.
The traditional-use heritage
Take ashwagandha as the headline example. According to a review retrieved from PubMed, ashwagandha (also called "Indian ginseng") has been used in Indian systems of medicine for around 3,000 years and is classed among adaptogenic plants, with withanolides such as withaferin A among its characteristic constituents (Mandlik Ingawale & Namdeo, 2020, DOI). That deep heritage is a big part of why these plants are popular today, though heritage is a cultural and historical point, not a modern medical claim.
How to think about adaptogens sensibly
The honest framing is this: adaptogens are a traditional category of plants with long histories of use, which modern supplements present on the basis of their composition and that heritage. They are not a magic fix, and in the UK they cannot be marketed with claims to treat stress, anxiety or any condition. The sensible way to judge an adaptogen supplement is on transparency, which plant, which part, what extract strength, and quality, exactly as you would any botanical. We cover ashwagandha's standardisation in what standardised to 5% withanolides means and the extract itself in what is KSM-66 ashwagandha.
How our adaptogen range is formulated
Our headline adaptogen is Ashwagandha, using KSM-66 standardised root extract with L-theanine and vitamin B6, presented transparently on its composition. Vitamin B6 is included partly because, unlike the botanical, it carries authorised claims (including for normal psychological function and the nervous system).
The takeaway
An adaptogen is a traditional category of plants, a term coined in the mid-20th century, used to group herbs like ashwagandha, rhodiola and ginseng that share long histories of traditional use associated with vitality and resilience. It is a heritage-based classification, not a regulated health claim, so judge any adaptogen supplement on the transparency and quality of the plant and extract it uses.
