What did @thewellnesspharm actually say?
The creator listed four "biohacks" to feel "superhuman": taking nootropics (specifically L-theanine), cold showers or cryotherapy, electrolytes, and B complex vitamins. They also spent a chunk of the video promoting a product called E-boost, which they say contains both L-theanine and B vitamins.
The specific claims worth examining: L-theanine "activates alpha brainwave activity" and boosts dopamine for creativity. Cold exposure "stimulates endorphins" and improves resilience. Electrolytes maintain "ion balance" for brain signaling. And vitamin B6 is a "precursor to serotonin production" that improves mood. These are mostly real mechanisms, but the framing ranges from reasonable to oversimplified to quietly wrong in places.
Does the science back this up?
Partially, yes. The L-theanine and cold exposure claims have the most legitimate research behind them. The B6-serotonin connection is real but badly oversimplified. The electrolyte claim is true in a baseline sense but misleading in context.
On L-theanine: there is genuine evidence that it increases alpha-wave activity in the brain. Nobre et al. (2008, Asia Pacific Journal of Clinical Nutrition) found that 50mg of L-theanine significantly increased alpha-wave production within 45 minutes. A separate review by Hidese et al. (2019, Nutrients) found improvements in attention and reaction time. The dopamine claim is fuzzier. L-theanine does modulate neurotransmitter activity, but calling it a direct dopamine booster for "creativity" stretches what the data actually shows in humans.
On cold exposure: Mooventhan and Nivethitha (2014, North American Journal of Medical Sciences) found cold water immersion can trigger norepinephrine release, not just endorphins, which is relevant to the focus and resilience claims. The "endorphin" framing is an oversimplification of the actual neuroendocrine response.
What did they get wrong (or right)?
They got the B6-serotonin relationship technically right but practically misleading. B6 is indeed a cofactor in the conversion of tryptophan to serotonin. But the leap from "B6 as cofactor" to "puts you in a better mood" skips several steps, including the fact that most people eating a normal diet are not B6-deficient enough for supplementation to meaningfully shift serotonin output. Young (2007, Journal of Psychiatry and Neuroscience) outlines this pathway clearly, and the nuance matters.
The dopamine claim around L-theanine is where the video is most loose. Saying L-theanine "boosts dopamine" as a standalone fact implies a pharmacological effect that the current human evidence does not strongly support at typical supplement doses. Animal studies show dopamine-related activity, but translating that to "boosts creativity" in humans is speculative.
What they got right: the alpha-brainwave mechanism for L-theanine is legitimate. The ion-balance role of electrolytes in neural signaling is textbook neuroscience. The B vitamin cofactor claim is accurate. And cold exposure does trigger real neurochemical responses. None of this is made up, it is just packaged more confidently than the evidence warrants.
What should you actually know?
If you are considering any of these approaches, the risk profile is low for most of them, which is actually a fair point in the video's favor. L-theanine at 100-200mg is considered safe and well-tolerated. Cold showers cost nothing and carry minimal risk for healthy adults. B vitamins are water-soluble, meaning excess is excreted rather than stored. Electrolytes are essential, though most people with a balanced diet are not deficient.
The bigger issue is the product plug embedded in the middle of the health claims. Recommending a specific branded product, E-boost, while citing the science of its ingredients is a classic content marketing structure. That does not mean the product is bad, but it means you should not treat the science citations as independent validation of that specific product.
Also worth noting: this video was categorized under peptide therapy by the platform. None of the four recommendations here are peptides. L-theanine is an amino acid found in tea. If you are exploring peptide-based approaches for cognitive performance or recovery, that is a different conversation entirely, one that requires clinical oversight rather than a TikTok recommendation.
Bottom line
This video is mostly harmless and occasionally accurate. The mechanisms cited are real, even if the confidence level in the claims exceeds what the studies actually demonstrate. The product recommendation embedded in the science talk is the part that deserves your skepticism, not the biology itself.
