There are several factors to consider. Maca may modestly boost libido after 6 to 12 weeks, but evidence that it improves erection firmness in men over 65 is limited, so it is best used with proven treatments and lifestyle changes. Key cautions and next steps, including ruling out cardiovascular or metabolic causes, reviewing thyroid and hormone-sensitive conditions, possible medication interactions, dosing, and when to seek care, are outlined below.
Erectile dysfunction (ED) becomes more common as men age. If you’re over 65 and curious about natural remedies, you may have come across claims that maca root can help. Below, we’ll explore what maca is, what the science says, and what you can realistically expect.
• Prevalence
– Up to 40–50% of men over 65 experience some degree of ED.
– Causes include changes in blood flow, nerve function, hormone levels, and certain medications.
• Common risk factors
– Cardiovascular disease or atherosclerosis
– Diabetes
– High blood pressure or cholesterol
– Obesity
– Chronic stress, anxiety, or depression
– Hormonal changes (e.g., lower testosterone)
– Medications (blood pressure pills, antidepressants)
• Importance of a medical check
– ED can signal underlying health issues.
– Treating the root cause—rather than just symptoms—offers the best long-term results.
Lepidium meyenii, commonly called maca, is a Peruvian plant in the cruciferous family (like broccoli). The root, usually dried and ground into powder, has been used for centuries to boost energy, stamina, and fertility.
Key points:
A 2002 study by Gonzales and colleagues looked at healthy men taking maca powder for 12 weeks. Here’s what they found:
• Improved sexual desire
– Participants reported a modest increase in libido compared to placebo.
– Effects became noticeable around week 8.
• No change in testosterone
– Blood tests showed no significant difference in serum testosterone levels.
– Suggests maca’s effects are not driven by boosting male hormones directly.
What this means for men over 65:
Other research highlights:
If you decide to try maca root for erectile dysfunction, keep these realistic expectations in mind:
Modest benefit on libido
• Some men notice a slight uptick in sexual desire after 6–8 weeks.
• Not everyone experiences a clear effect.
Limited impact on erection firmness
• If your ED is driven mainly by poor circulation or nerve damage, maca alone won’t be enough.
• It may help as part of a broader plan (see below).
No rapid “miracle cure”
• Herbal remedies tend to work gradually.
• Consistency is key; expect to take maca daily for at least 8–12 weeks before judging its effect.
Individual variability
• Genetics, overall health, diet, activity level, and stress all influence results.
• What works for one man may not work for another.
When considering maca root for erectile dysfunction, follow these guidelines:
• Choose a reputable brand
– Look for third-party testing (e.g., USP, NSF).
– Check for purity and absence of contaminants.
• Typical dosage
– 1,500–3,000 mg per day, usually split into two doses with meals.
– Start at the lower end to assess tolerance.
• Potential side effects
– Mild: Digestive upset, gas, bloating.
– Rare: Headaches or sleep disturbances.
– If side effects persist, reduce dose or stop.
• Interactions & precautions
– Hormone-sensitive conditions (e.g., prostate or breast cancer): discuss with your doctor.
– Thyroid disorders: maca contains goitrogens, which may affect thyroid function in susceptible individuals.
– Blood pressure medications: monitor blood pressure regularly if you’re on meds.
Maca root is just one piece of the puzzle. Enhancing erectile function after 65 usually requires a multi-pronged approach:
• Lifestyle modifications
– Regular exercise (especially aerobic and pelvic-floor exercises)
– Healthy diet rich in fruits, vegetables, whole grains, lean protein
– Weight management
– Adequate sleep and stress reduction techniques (meditation, yoga)
• Medical treatments
– PDE-5 inhibitors (e.g., sildenafil, tadalafil) remain first-line for many men.
– Testosterone therapy (if clinically low levels confirmed)
– Other options: penile injections, vacuum erection devices, implants (for severe cases)
• Psychological support
– Counseling or sex therapy can address performance anxiety, relationship issues, or depression.
Don’t ignore signs that could suggest a serious health condition. Consider scheduling a check-up if you experience:

Always speak to a doctor about anything that could be life-threatening or serious. Only a qualified healthcare provider can evaluate your overall health, run necessary tests, and recommend appropriate treatments.
• Maca root for erectile dysfunction offers modest libido benefits, with limited evidence for improving erection firmness.
• Effects usually appear after 6–12 weeks of consistent use.
• Safety profile is generally good, but discuss any hormone-sensitive conditions or thyroid issues with your doctor.
• For best results, combine maca with lifestyle changes, medical treatments, and psychological support as needed.
• Don’t hesitate to get a full medical evaluation and speak to a doctor about serious concerns or persistent symptoms.
By understanding what maca can and cannot do, you can make an informed choice and set realistic expectations. Whatever path you choose, maintaining open communication with your healthcare provider is key to managing ED effectively after 65.
