This Black Friday skip the sale. Save lives.

Happy Black Blood Friday. No discount codes here. This year, we have something better than a sale: saving lives.

Today's Blood Friday edition:

🩸 Why blood donations matter, especially right now.
💉 Where your donation goes and who it helps.
🆎 Why most people rule themselves out (when they should not).
(Plus: Our founder Max's donation story and how it improved his biomarkers.)

Every two seconds, someone in the U.S. needs a blood transfusion.

Yet only 3% of eligible Americans donate, and that drops 20% after Thanksgiving.

This year, instead of chasing Black Friday deals, we invite you to do something different: give blood. And as we enter the season of giving, this is the moment when blood is critically needed.

We've teamed up with the American Red Cross to ensure a safe and reliable blood supply is available for patients in need.

For the first 1,000 to donate blood or money, we’ll give you a Superpower membership, on us.

It’s our way of saying thank you for showing up for someone else.

Blood can’t be manufactured. It only comes from people like you ❣️

❤️ One blood donation can save three lives.

Most people underestimate how far one donation goes. It gets separated into red cells, plasma, and platelets, each sent to a different patient for a different need.

Your donation may help:

• Patients undergoing chemotherapy for cancer

• Individuals with bleeding or clotting disorders

• People with autoimmune or immune-mediated conditions

• Patients with sickle cell disease who rely on long-term transfusion support

• Premature babies and critically ill newborns

• Trauma victims requiring rapid resuscitation

• Patients recovering from transplants, cardiac surgery, or major operations

Just one donation can help save up to three lives.

Different donation types, different kinds of impact

Every type of donation makes a meaningful difference [types of blood donations]. But some blood components expire faster than Black Friday deals, especially platelets and universal red cells.

When supplies run low, there is no back room and no extra inventory. Hospitals cannot stockpile blood bags the way we stockpile bargains. They rely on continuous donations in real time, exactly when patients need them.

The holiday season is one of the hardest times of the year for blood supply. Donations consistently drop at the exact moment when many patients, including those who will not be spending the holidays at home, depend on transfusions to stay stable, continue treatment, or recover from surgery.

Your donation in the coming weeks becomes someone’s holiday gift.

💡 …and here’s something most people don’t know: there may be health benefits for donors, too.

While the purpose of donating blood will always be to help someone else, there’s emerging research showing that donation may support your own health.

A standard whole-blood donation removes about 200–250 mg of iron. To rebuild the red cells you’ve donated, the body naturally draws on stored iron, leading to a temporary drop in ferritin.

For many people, especially men, postmenopausal women, and those taking iron supplements, iron stores can slowly build up over time. Excess iron can drive oxidative stress, and higher ferritin levels have been linked in observational studies with increased metabolic and vascular strain.

Research also shows:

• Lower cardiovascular risk markers in regular donors [vascular function] [insulin sensitivity] [vascular integrity] [heart disease protection]

• Lower all-cause mortality in long-term donor cohorts [the research]

• Associated with improved metabolic markers [clinical trial]

Plus, regular donors tend to be healthier as a group, and large studies show that even frequent donation is safe and well tolerated for most healthy adults [INTERVAL trial].

🆎 Max’s Story: When donating helped more than one person.

Earlier this year, Max (one of Superpower’s founders) noticed his energy dipping and his recovery feeling off. A blood test revealed that his iron stores were much higher than ideal, a common issue many people don’t realise they have.

But then he donated blood.

Within a few months, his iron levels moved back into the healthy range, as did his liver enzymes, hemoglobin, and hematocrit.

It wasn’t just good karma. It was physiology, and a reminder that understanding your biology helps you stay healthy enough to help others too.

🩸 Am I allowed to donate? (Most people are!)

A lot of people assume they’re ineligible when they’re not.

Here are the quick facts:

• Most adults in good general health can donate.

• Hemoglobin is checked at every visit to ensure safe levels.

• Many common conditions like thyroid issues, controlled hypertension, and past infections do not disqualify donors.

• Age limits are wider than most people realise.

• A typical whole blood donation takes about 8–10 minutes.

Give the gift of life. Get the gift of health.

Save a life. Strengthen your health.
