The baking soda trick for men with ED involves mixing 1/2–1 teaspoon of sodium bicarbonate into 8 ounces of water and drinking it daily for up to a week, aiming to slightly raise blood pH so penile smooth muscle relaxes and blood flow improves. There’s no clinical proof it helps ED, and it can pose risks (high sodium load, metabolic alkalosis, blood-pressure increases, drug interactions), so talk with a clinician—especially if you have heart, kidney, or BP issues. There are several factors to consider, including safe use, red flags, and proven options like PDE5 medications and lifestyle changes; see the complete details below.
Erectile dysfunction (ED) affects many men, leading them to seek both medical treatments and at-home remedies. One popular home remedy is the “baking soda trick for men.” This guide explains what it is, how it’s thought to work, what the research says, and important safety considerations.
The baking soda trick involves mixing sodium bicarbonate (baking soda) into water and drinking it, with the goal of improving erections. Proponents claim that by creating a mild, temporary “alkalosis” (raising blood pH), the body’s blood vessels relax more easily, potentially boosting blood flow to the penis.
Typical instructions:
While no large clinical trials have tested baking soda specifically for ED, the theory draws on basic physiology:
Blood pH and Vascular Tone
Research in sports medicine (Carr AJ, Hopkins WG, & Gore CJ, 2011) shows that acute alkalosis can improve muscle performance by buffering lactic acid. Although this applies to skeletal muscle, some suggest a similar effect in smooth muscle—such as that in the corpora cavernosa of the penis.
Corpora Cavernosa Physiology
Studies of penile tissue (Eardley I, Portsmouth S, & Caldwell D, 2000) reveal that pH influences how well smooth muscle relaxes in response to nitric oxide (NO). Higher pH (more alkaline) may enhance NO-mediated relaxation, a key step in achieving an erection.
Nitric Oxide Pathway
Erection depends on NO release, which triggers smooth muscle cells in penile arteries to relax, increasing blood flow. If alkalosis amplifies this pathway even slightly, the theory goes, erections could improve.
If you’re curious about the baking soda trick for men with ED, follow these guidelines:
Start Small
• Use only ½ teaspoon of baking soda in a full glass of water.
• Take it once daily, ideally in the morning.
Monitor Your Body
• Watch for stomach upset, heartburn, or nausea.
• If you feel dizzy, weak, or experience muscle spasms, stop immediately.
Limit Duration
• Do not continue daily use for more than 5–7 days without a break.
• Extended use may lead to metabolic alkalosis or electrolyte imbalances.
Check Your Blood Pressure
• Baking soda is high in sodium. If you have high blood pressure, heart disease, or kidney problems, consult your doctor first.
Using baking soda regularly can carry risks:
Metabolic Alkalosis
Excessive alkali can disrupt acid–base balance, causing weakness, confusion, and muscle twitching.
Electrolyte Imbalance
High sodium intake may lead to fluid retention, high blood pressure, and strain on the heart.
Digestive Issues
Bloating, gas, and stomach cramps can occur, especially on an empty stomach.
Drug Interactions
Baking soda may interfere with certain medications (e.g., antacids, antibiotics). Always check with a pharmacist or doctor.
While exploring home remedies, remember that ED can signal deeper health issues:
Cardiovascular Risk
ED often precedes heart disease. If you experience chest pain, shortness of breath, or unexplained fatigue, seek immediate medical attention.
Hormonal Imbalances
Low testosterone or thyroid problems can cause ED. A doctor can order blood tests to check hormone levels.
Neurological Concerns
Diabetes, multiple sclerosis, and spinal injuries can impair nerve signals needed for erection.
Psychological Factors
Stress, anxiety, and depression play a major role. Counseling or therapy may be recommended.
If you’re unsure about the cause of your symptoms, consider doing a free, online symptom check for Erectile Dysfunction.
Alongside—or instead of—the baking soda trick, consider proven strategies:
For persistent or severe ED, speak to a doctor. Early diagnosis and treatment can not only improve sexual function but also reveal underlying health issues that deserve attention.
