Read from .env file and set as bash variables

How can I read an .env file and set the variables as bash variables? Currently, I'm able to read it and export them as environment variables.

If the file contains the variables:

DB_NAME=mydb
DB_PASSWORD=abcd1234

Then, DB_NAME and DB_PASSWORD will be bash variables and they will contain the respective values.

If a text file is formatted as

DB_NAME=mydb
DB_PASSWORD=abcd1234

then these variables can be set in the current bash shell simply by sourcing the file as:

source my_custom.env
