In video game culture, players often shout 'running low' to teammates regarding 'ammo' or 'health' (HP).

What It Means
Run low describes a state of depletion. It means you still have some of something, but not much. Think of a gas gauge dipping toward the red zone. You aren't totally empty yet, but you need to act soon. It is the perfect middle ground between 'full' and 'gone'.
How To Use It
You usually follow this phrase with the word on. For example, you run low on coffee or time. You can also use it as a standalone statement about a supply. If the pantry is empty, you say the snacks are running low. It is a very active phrase. It suggests that the situation is changing right now.
When To Use It
Use it when you need to give a warning. It is great for grocery lists or office supplies. Use it at work when a deadline is approaching. Use it with friends when your phone battery is at 5%. It sounds natural in almost any daily conversation. It helps you sound proactive rather than panicked.
When NOT To Use It
Do not use it for people unless you mean their energy. You wouldn't say a person is running low to mean they are short in height. Also, avoid using it for things that don't have a quantity. You don't run low on a song or a movie. If you are completely out of something, use run out instead. Run low is only for when a little bit remains.
Cultural Background
In English-speaking cultures, being prepared is highly valued. Using run low is a polite way to ask for more without being demanding. It signals that you are paying attention to your surroundings. It likely comes from old maritime or mechanical terms regarding fluid levels in tanks. It has been a staple of English idioms for over a century.
Common Variations
You will often hear running low for current situations. You might hear running on fumes if the situation is desperate. Another common one is low on [something]. For example, 'I am low on cash.' However, adding the word run makes it feel more like a process. It shows that the supply is actively disappearing.
使い方のコツ
The phrase is highly versatile and works in almost any register. The most important grammatical rule is using the preposition 'on' when identifying the resource.
The 'On' Rule
If you name the item, you MUST use 'on'. If you don't name the item, just say 'It's running low.'
Don't say 'Run Small'
Some learners say 'running small' for supplies. This is incorrect. 'Running small' is only used for clothing sizes (e.g., 'This shirt runs small').
Use it for Patience
Saying 'My patience is running low' is a very natural, native-sounding way to warn someone you are getting annoyed.
Polite Requests
Use 'running low' to ask for things indirectly. 'We're running low on coffee' is more polite than 'Buy more coffee!'
