None of these six products has been tested in its own clinical trial, and no supplement treats lymphoedema.[23][25] The ingredients with the best evidence are horse chestnut and butcher's broom, and that evidence is for vein-related leg heaviness and swelling.[8][13] Lymph Relief has the most transparent label; Lymph Savior, LymphaFlo and Lymph Tonic contain horse chestnut; Lymph Tonic is the only liquid; Flush Factor Plus is a short-term diuretic-style formula.

Before you buy anything
Get medical help first if…
- Call 999 (or your local emergency number) if swelling comes with chest pain or tightness, breathlessness, coughing up blood, or feeling faint. These can be signs of a blood clot in the lungs.[24]
- Get an urgent GP appointment or call 111 if swelling is in one leg only with no clear cause, is sudden, painful or getting worse, the skin is red or hot, or you have a high temperature.[24]
- See a GP if swelling in both legs has not improved after a few days, or you have a heart, kidney or vein condition.[24]
For everyday puffiness, moving regularly, raising your legs, cutting salt and keeping a healthy weight have better support than any supplement.[24] Read our exercise guide and herb evidence guide.

Head-to-head comparisons
Common questions
What is the best lymphatic drainage supplement?
There is no proven best product, because none has been tested in its own trial. Lymph Relief has the clearest label; products with horse chestnut have the best ingredient evidence, for vein-related symptoms.[8]
Do lymphatic drainage supplements work?
There is no good evidence that any finished lymph supplement drains lymph or treats lymphoedema. Treatment for lymphoedema is compression, skin care, exercise and specialist massage.[23]
Are these supplements safe?
Several contain ingredients that interact with blood thinners, thyroid or diabetes medicines, or are unsuitable in pregnancy. Check the cautions above and ask a pharmacist.
