What did @elevatemd actually say?
The creator offered three "science-backed" fixes for perimenopause anxiety: L-theanine combined with magnesium glycinate (called "literally nature Xanax"), holding an ice pack on your neck or chest for 10-15 minutes to activate the vagus nerve, and progesterone therapy. She also claimed progesterone production starts declining "around the age of 25" and that these hacks address heart palpitations, insomnia, and what she called "internal trimmers" (likely internal tremors). The tone was personal and enthusiastic, leaning on self-reported experience as much as science. Worth noting upfront: personal testimony is not the same as evidence, and "science-backed" gets used loosely on TikTok health content.
Does the science back this up?
Partially, yes. L-theanine and magnesium glycinate both have legitimate supporting research, though neither is remotely comparable to a benzodiazepine. Vagal cold stimulation has real physiological backing. Progesterone's role in anxiety during perimenopause is well-supported but more complicated than presented here.
L-theanine, an amino acid found in green tea, has demonstrated anxiolytic effects in multiple small trials. Hidese et al. (2019, Nutrients) found that 200mg daily reduced stress and anxiety in healthy adults. Magnesium glycinate's calming effects relate to magnesium's role in GABA receptor modulation. A 2017 systematic review by Boyle et al. (Nutrients) confirmed magnesium supplementation showed benefit for subjective anxiety in mild-to-moderate cases. These are real effects. They are not Xanax effects.
Cold stimulation of the vagus nerve is supported by research on the diving reflex and vagal tone. Jungmann et al. (2018, Applied Psychophysiology and Biofeedback) showed cold water face immersion reduced acute stress markers. Holding an ice pack on your neck is a diluted version of this, but the underlying mechanism is credible.
Progesterone's anxiolytic properties are tied to its conversion to allopregnanolone, a GABA-A receptor positive modulator. Freeman et al. (2001, Menopause) and subsequent work have confirmed that falling progesterone during perimenopause disrupts GABAergic signaling, contributing to anxiety and sleep disruption. The hormone claim has the strongest clinical grounding of the three.
What did they get wrong (or right)?
The "nature Xanax" framing is the biggest problem here. Benzodiazepines act directly and powerfully on GABA-A receptors. L-theanine and magnesium influence mood through indirect, modest pathways. Calling this combination "nature Xanax" sets expectations that the evidence cannot support and could discourage someone from seeking actual treatment for a serious anxiety disorder.
The progesterone decline claim is also off. The creator says progesterone "starts to naturally decline around the age of 25." This conflates peak fertility with clinically meaningful hormonal decline. Progesterone does fluctuate across the menstrual cycle throughout reproductive years, and some research notes a gradual shift in luteal phase progesterone in the late 30s. But framing 25 as the starting point for decline that warrants supplementation is misleading. The Endocrine Society places perimenopause-related hormone disruption typically in the mid-to-late 40s for most women.
- L-theanine and magnesium glycinate: real supporting evidence, overclaimed as "nature Xanax." Rating: mostly accurate.
- Ice pack vagus nerve hack: plausible mechanism, limited direct evidence for this specific application. Rating: mostly accurate.
- Progesterone therapy for anxiety: well-supported in perimenopause, but "I would not survive without it" is anecdote, not protocol. Rating: accurate in context, but framing is imprecise.
- Progesterone declining at 25: misleading. The clinical decline relevant to perimenopause symptoms is not typically a 25-year-old's concern.
What should you actually know?
If your anxiety is spiking in your 40s and your cycle is changing, hormonal contributions are absolutely real and worth discussing with a clinician. The research on allopregnanolone and GABAergic signaling gives perimenopause-related anxiety a solid biological explanation. This is not "in your head," and the creator is right to validate that.
But the gap between "these supplements helped me" and "these are science-backed treatments for your anxiety" is significant. L-theanine and magnesium are low-risk, reasonably evidenced options for mild anxiety support. They are not substitutes for evaluation of a clinical anxiety disorder, thyroid dysfunction, or other conditions that can mimic or worsen in perimenopause.
Progesterone therapy, specifically micronized progesterone, is an FDA-recognized treatment used within hormone therapy regimens. It is not something to start based on a TikTok video. Dose, formulation, and whether you need it at all depend on your specific hormonal picture. A telehealth provider or OB-GYN familiar with menopause medicine can order relevant labs and walk through your options. The Menopause Society (formerly NAMS) publishes evidence-based guidelines that are worth reading if you want to go into that conversation informed.
