The club has signed up to a suicide charity's campaign to make workplaces more supportive.
Sheffield United have become only the second professional football club to sign up for a suicide prevention charity's workplace pledge.
The Championship side said the initiative, created by Baton of Hope, was aimed at teaching people to spot the signs and how to speak to someone who may be feeling suicidal.
The club said digital messages highlighting the campaign would be displayed at Saturday's match against Birmingham City and at the women's team fixture against Southampton on Sunday.
Men's captain Japhet Tanganga said suicide was a "massive issue" and he hoped the pledge would encourage people "to fully recognise the magnitude of this national catastrophe and urge people not to suffer alone".
Women's captain Ella Kinzett added: "We know now that the vast majority of suicides are preventable and talking about it is the first step when it comes to standing up to suicide."
Mike McCarthy, who founded Baton of Hope, said he was delighted Sheffield United had agreed to sign up, describing it as "basically a kite mark of best practice in suicide prevention".
He said: "It affects us all to one degree or another because nobody, tragically, is immune to suicide.
"In all kinds of industries we need to make the workplace psychologically safer for everyone."
Player welfare at Sheffield United has come under scrutiny in recent years following the death of former player Maddy Cusack, who was found dead at her home in 2023.
There has been no official explanation for her death, though police said at the time it was not considered suspicious.
Her family has previously said she had no longstanding mental health issues, but faced financial pressures in the months before.
An investigation into the player's experiences at the club, which concluded in December 2023, found no evidence of wrongdoing.
A delayed inquest to examine the circumstances of her death is due to take place in early January.
Oxford United were the first club to sign up to the Baton of Hope pledge, where former Rotherham United and Sheffield Wednesday midfielder Will Vaulks now plays.
Speaking at the time, Vaulks, who lost two grandparents to suicide, said men were "notoriously not great" at talking about their mental health, but added: "That's where football brings us all together - the match day talking about the game, you could actually just delve a little bit deeper with your friends.
"You guys and girls in the stands, just have a little bit more of a conversation about each other - maybe stop slagging off my first touch for a minute and check on your mate next to you."
