If you’ve spent any time with classic sci-fi or fantasy stories, you’re likely familiar with the trope of the magical love potion – and the cautionary tales of what happens when you strip away someone’s autonomy. Now, Silicon Valley is attempting to bring that fiction to life. Speaking to an audience of tech insiders, Anduril co-founder Palmer Luckey proposed “oxytocin doping” as a pharmacological hack to “end the tragedy of divorce.”
Suggesting that administering oxytocin to unhappy spouses could chemically repair failing relationships, Luckey dismissed traditional marital counseling in favor of a biological shortcut. His comments sparked immediate backlash, with critics pointing out that chemically suppressing marital discontent ignores the root causes of conflict – and risks trapping partners, particularly women, in toxic or abusive dynamics without recourse.
Oxytocin is neither a romantic miracle cure nor a Silicon Valley biohack. It is a potent, complex neurochemical and a strictly managed clinical medication with high-stakes physiological consequences.
What is “oxytocin doping”?
Though Palmer Luckey specifically used the term “oxytocin doping” in his remarks, the application is still speculative at this time and does not formally exist. Oxytocin is a hormone produced in the hypothalamus and released into the bloodstream by the posterior pituitary gland. It plays important roles in childbirth and breastfeeding, helping stimulate uterine contractions and the release of breast milk. Researchers have also investigated its involvement in social recognition, emotional processing, and interpersonal bonding, which is why it is sometimes referred to as the “love hormone.” Since oxytocin is sometimes administered to women in medical settings to induce labor or control postpartum bleeding, it’s not a complete logical leap to assume that medical professionals could utilize it for other purposes, like emotional regulation.
Still, Palmer Luckey’s suggestion that oxytocin could be free-based to influence feelings of closeness or attachment between romantic partners is not medically confirmed. Some intranasal sprays have been used in scientific studies examining the hormone’s effects on human behavior, but research findings have been inconsistent. A 2014 study from the University of Oxford highlighted a possible link to medical oxytocin and human pair-bonding, but ultimately failed to establish any concrete evidence that taking oxytocin can reliably make someone fall in love, repair a strained relationship or prevent a couple from splitting up. The Food and Drug Administration currently approves oxytocin medications for use in obstetric care, but the organization has never formally recognized, nor approved, any effort to use the hormone in influencing romantic attachment.
The flawed science of chemical connection
The idea behind Palmer Luckey’s proposal is rooted in research showing that oxytocin is involved in the biological processes associated with social bonding. If we follow his logic, it seems he’s painting a picture in which a woman becomes mad at her husband and, rather than fighting with him or getting to the root of their disagreement, she takes a drug to magically fall in love all over again. If such a drug were to exist, it could have incredible ramifications on relationships, social groups and even warfare, but it is still quite a stretch from objective reality.
Blavity Health spoke with Dr. Ben Garrett, Owner and Counselor at Chilliwack’s Vedder Counseling for some clarity on the matter. As he explained, “Marriages do not fail due to lack of oxytocin. Marriages fail because of unresolved negative feelings and unmet needs, which, over time, result in communication breakdowns… It is unreasonable to expect a chemical to replace actual interactions and teach a couple how to resolve their issues and relate to one another.”
Despite the clear flaws in Luckey’s logic, researchers have explored whether synthetic oxytocin could be administered through a nasal spray in experimental settings. A 2024 study even found some links between oxytocin and relationship dynamics, including emotional and physiological responses between partners, though researchers ultimately concluded that those dynamics were too complex to be properly measured. For Luckey’s proposal to function as a credible treatment, researchers would need to establish whether oxytocin meaningfully improves relationship outcomes, what dosing would be appropriate and whether repeated use is medically safe. For the time being, there is no evidence to suggest oxytocin can make couples stay together or serve as a substitute for basic relationship counseling.
The biological and ethical hazards of at-home doping
During Palmer Luckey’s public remarks, he stressed that “most of the people who don’t want to stay together should stay together, especially for their kids.” The tech financier also argued that oxytocin is safe, well understood, and “totally unregulated, which is great.” As he sees it, “unregulated spaces are a lot easier.”
In truth, taking unregulated hormone treatments is never advisable outside of a medical setting. As Dr. Garrett pointed out in our discussion, “There is no standard dose for oxytocin when it is sold or used outside of a medical context, and it has not been approved for use in relationship therapy. If someone is considering using it, they should consult a physician. There is a risk in using it that a quick fix may give couples the false impression that they don’t have to work on issues they do. It also poses the risk that it may be used to treat a relationship difficulty without the full understanding and/or consent of both people in the relationship.”
In addition to being unregulated, researchers have reported a wide range of reactions to oxytocin. That uncertainty is a huge factor when considering a substance intended to influence complex experiences such as trust, attachment or romance. When administered improperly in obstetric settings, patients have reported excessively strong or prolonged uterine contractions, as well as other serious complications. Though this can be quickly remedied by medical professionals, it can also be extremely painful. There’s very little information available regarding these kinds of responses to oxytocin taken by nasal spray, but you certainly wouldn’t want to mess around with the hormone at home, just to become patient zero for an unregulated reaction. Ultimately, the concern is not that oxytocin is inherently dangerous in every setting, but that its safety and effectiveness for unapproved purposes have not been established.
Risks and side effects
As stated, research into intranasal oxytocin is fairly scant at this time. Some studies have reported potential side effects including headaches, dizziness, nausea, drowsiness, and nasal irritation. Participants have also reported restlessness, anxiety, or unusual sensations after administration, although these symptoms have not consistently occurred more often than with a placebo. One trial published in Science Direct even outlines a difference in male and female responses, citing massive variances in women on oxytocin due to the shifts in their menstrual cycle. Because the hormone influences processes involved in social perception and emotional responses, researchers have had substantial difficulty documenting every possible reaction and determining whether these correlate with the drug or with external factors. Products sold online without appropriate medical oversight can pose additional concerns, particularly when their ingredients and concentration are not properly labeled. Palmer Luckey suggested that his audience head to Sigma-Aldrich, a biotech medical supplier, and purchase a kilogram of the substance for at-home use, but this is a tremendously unsafe notion that should not be attempted by anyone.
There have been documented complications with the hormone which include excessive uterine contractions. The ABC Law Center has confirmed that in the most severe cases, this can result in uterine rupture, severe bleeding, and reduced oxygen supply to a fetus in pregnant patients. These risks are especially relevant during labor, and should not be assumed to apply in the same way to intranasal administration. Oxytocin is also said to affect the body’s regulation of water. With prolonged, high-dose intravenous infusions, its antidiuretic effects can contribute to water intoxication and dangerously low blood sodium levels. When not properly monitored, this could cause seizures or loss of consciousness.
Because oxytocin has not been established as a safe or effective treatment for improving romantic relationships, no one should self-administer it for this purpose, under any circumstance. Simple therapy or couples therapy is widely considered safer, more effective, and well-documented for repairing a broken marriage. A 2019 analysis of behavioral couples therapy concluded that the practice was overwhelmingly positive for couples willing to give it an honest shot, while no such studies have ever been as conclusive in regard to oxytocin. This path may not be right for every couple, but not every couple is meant to last a lifetime. The true flaw with Palmer Luckey’s view is that it fails to account for spouses who drift apart, prefer different things out of life, or simply become incompatible with time. These things can all be discussed with a licensed therapist, and each patient can build an action plan for seeking divorce or sticking around to do the heavy emotional labor associated with repairing their relationship, according to their specific situation. Furthermore, Luckey’s comments fail to account for marriages where one or both parties are suffering from abuse. In such cases, there is no magical drug that will allow a couple to persevere as though nothing is wrong.
Real solutions for relationship health
Rather than experimenting with hormones to influence attachment or behavior, couples experiencing relationship difficulties can turn to approaches that address the underlying causes of conflict. As stated, couples therapy can provide a structured setting to work through communication problems, rebuild trust, clarify expectations and decide how to move forward. Simple daily habits can also support healthier relationships, without medical intervention. Partners can practice listening without interrupting, expressing concerns without blame and taking breaks when arguments become overwhelming. Setting aside regular time to check in about stress, household responsibilities, finances, or other emotional needs may help prevent resentment from accumulating. Of course, these things only apply when both parties are prepared to put in the work, and both parties agree that the relationship is worth saving.
If emotional regulation is a core concern, established mental health treatments offer a more evidence-based option than experimenting with oxytocin. People experiencing persistent sadness, anxiety, irritability or difficulty managing their emotions can discuss their symptoms with a healthcare provider, who can assess potential causes and recommend appropriate care.
Depending on the diagnosis, treatment may include medication. In his comments, Palmer Luckey argued that SSRIs (selective serotonin reuptake inhibitors) are not acceptable in his view, though he doesn’t offer any explanation as to why. In reality, these medications are commonly prescribed for depression and certain anxiety disorders, to varying degrees of success. SSRIs aren’t specifically designed to regulate relationship dynamics, but they could do wonders to address the root causes of depression or other mental health issues that are impacting a rocky marriage.
Bottom line
When billionaire entrepreneur Palmer Luckey suggested so-called “oxytocin doping” to help struggling couples remain happily married, he raised a number of provocative questions. While it may be nice to imagine a world where a love hormone magically makes your spouse stick it out until the bitter end, that simply isn’t the world we’re living in. Research has not established that taking oxytocin can reliably strengthen romantic relationships or prevent divorce, and studies of its recreational effects have produced almost no conclusive findings to speak of. Although research is still being conducted on short-term intranasal oxytocin, the likelihood that this research results in a Love Potion #9 scenario is little more than the wishful thinking of a sci-fi fan.
Frequently Asked Questions
What gives you the most oxytocin?
Oxytocin is released naturally during activities such as childbirth and breastfeeding. Some research suggests that affectionate touch, cuddling, and other forms of close social contact can also activate oxytocin within the brain. Still, no single activity is proven to produce the highest oxytocin levels in everyone, as responses vary by individual and circumstance. If you’re feeling down, it’s probably best to lean on the specific things that bring you joy rather than focus on artificially raising your oxytocin levels.
What vitamin increases oxytocin?
Though some nutrients have been investigated for their potential roles in hormone regulation, no vitamin has officially been established as a way to increase oxytocin levels the brain. Oxytocin can be derived from natural experiences such as hugging loved ones or sharing a romantic connection.
