    Adaptogen drinks in the UK: what they are and how to choose one

    What are the best adaptogen drinks in the UK?

    The short answer

    "Adaptogen" is a traditional herbal term, not an approved UK health claim. Ingredients often called adaptogens include Ashwagandha, Ginseng, Holy Basil, Rhodiola, Reishi and Cordyceps. No adaptogen drink is allowed to say it reduces stress or boosts energy because of these ingredients. Any approved claim on the can comes from added vitamins and minerals. To choose one, check the stated amount of each ingredient, the caffeine and sugar per can, and whether the brand publishes testing.

    AmountsMilligrams of each ingredient, not just a list of names

    SugarGrams per can, not only per 100ml
    ClaimsOnly vitamins and minerals can carry approved claims

    The trade-offs

    Grass & Co. drinks (FOCUS, RELAX, POWER)

    • Stated amounts: 1,000mg mushroom extract per can plus Ginseng, Ashwagandha or Holy Basil
    • Approved claims from added vitamins only
    • Low sugar and vegan
    • No adaptogen claim is allowed, so we cannot promise an effect
    • More expensive than a soft drink
    • POWER is high in caffeine; not for children or pregnancy
    The verdict

    Treat adaptogen drinks as a better swap for a soft drink, coffee or wine, not as a treatment. Pick the one that states its amounts, is honest about caffeine and sugar, and tastes good enough that you will keep drinking it.

    Where Grass & Co. loses

    If you want the most of a single herb, a capsule or tea of that herb gives you more for less money than any can. And if you want a caffeine hit, a plain coffee is cheaper than POWER.
