Do foods and supplements actually boost oxytocin levels?

What did @ashlinakaposta actually say?

The creator claims that low oxytocin levels cause anxious attachment in women, specifically by making you "crave external validation" and "attention from others." She says diet can help "sustain, build and increase" oxytocin levels, and recommends dark chocolate, honey, spinach, bananas, red chili peppers, and avocados. She also states there is "no spray that can give you oxytocin," which is worth flagging because intranasal oxytocin sprays do exist in research and clinical settings.

The framing here is that psychological attachment patterns are primarily driven by a hormone deficiency you can eat your way out of. That is a significant claim, and it deserves more scrutiny than a TikTok cheat sheet provides.

Does the science back this up?

Partially, but the creator is collapsing a complicated relationship between oxytocin and behavior into something much simpler than the evidence supports. Oxytocin is genuinely associated with social bonding and trust, but the link to anxious attachment specifically is not as clean as she presents it.

Some research does show associations between oxytocin signaling and attachment styles. Feldman (2017, Neuroscience and Biobehavioral Reviews) found oxytocin plays a role in social affiliation and stress buffering, but the direction of causation is unclear. Low oxytocin may not be causing anxious attachment so much as anxious attachment behavior might suppress oxytocin release. That is a meaningful difference.

On the dietary side, magnesium does appear to influence oxytocin receptor sensitivity. Durlach et al. (2004, Magnesium Research) noted that magnesium deficiency can impair oxytocin receptor function. But going from "magnesium supports receptor function" to "eat bananas to fix your attachment style" skips several steps. Dark chocolate contains phenylethylamine and flavonoids that may modestly affect mood-related neurochemistry, but direct evidence linking chocolate consumption to measurable oxytocin increases in humans is thin.

What did they get wrong (or right)?

The claim that there is "no spray that can give you oxytocin" is factually incorrect. Intranasal oxytocin has been studied extensively. Guastella et al. (2010, Biological Psychiatry) and multiple subsequent trials used intranasal oxytocin in clinical research. Prescription intranasal oxytocin does exist in some markets, though evidence for its clinical efficacy in behavioral applications remains mixed.

The creator also presents the oxytocin-anxious attachment link as established fact when it is still an active area of research with inconsistent findings. Bartz et al. (2011, Nature Reviews Neuroscience) specifically argued that oxytocin's social effects are highly context-dependent and can actually increase anxiety in some individuals.

On the other hand, she is not wrong that diet affects hormonal and neurochemical environments. Magnesium deficiency is genuinely common, and correcting a deficiency can have downstream effects on mood and stress hormones. That part is grounded. She is also right that lifestyle behaviors like physical touch, exercise, and social connection reliably stimulate oxytocin release, which she references when she mentions "all the activities that you're doing."

What should you actually know?

Oxytocin is real, important, and influenced by lifestyle. Anxious attachment is also real, and it has neurobiological components. But the creator's framing reduces a complex psychological pattern rooted in early experience, nervous system regulation, and learned behavior down to a hormone you can top up with honey in your coffee.

If you genuinely struggle with anxious attachment, that deserves more than a dietary intervention. Attachment patterns are primarily addressed through therapy, particularly approaches like Emotionally Focused Therapy (EFT) or attachment-based cognitive behavioral therapy, which have actual clinical trial support.

The dietary recommendations themselves are not harmful. Magnesium-rich foods, healthy fats, and whole foods broadly support metabolic and hormonal health. But eating spinach is not going to rewire an attachment pattern formed in childhood. Anyone who is working with a hormone specialist and finding value in that is not wrong to do so, but the specific claim that low oxytocin is the primary driver of anxious attachment in women is an oversimplification that could lead people away from more effective interventions.
