- 0:00Here's how you can increase your free testosterone levels naturally.
- 0:02And specifically what I did to almost double my own.
- 0:05No, it does not involve taking your SHPG as a matter of fact, mine increased.
- 0:09The only time you should be focusing on lowering your SHPG is if your levels are way above the normal reference range.
- 0:14In that case, you should be addressing whatever is causing it.
- 0:16But the first thing I did was help re-diverse by my gut microbiome after I had a round of antibiotics following wisdom teeth extraction.
- 0:23While literature is definitely lacking in this area, the more we learn about the gut,
- 0:27the more it seems to have an effect on overall health and thus, testosterone levels.
- 0:30I accomplished this by eating Greek yogurt, kimchi, sauerkraut, kombucha, and kafir,
- 0:35as well as making sure I was feeding the beneficial bacteria by consuming ample of mounts of prebiotics in the form of legumes, grains, fruits, and mix nuts.
- 0:43Stress management is also really important and I accomplished this by making sure I hit my sleep goal every night,
- 0:48which was closer to eight and a half to nine hours during this period.
- 0:51I also meditated twice once in the morning slash afternoon and once in the evening before bed.
- 0:56Do you have to meditate? Absolutely not.
- 0:58The goal here was to do something relaxing that lowers stress if your levels have been chronically elevated, which was the case in my situation.
- 1:04And obviously, you should be doing all the other things like adequate sun exposure, exercise, healthy diet, etc.
- 1:09I just believe these two were the biggest needle movers in my case.
Can you naturally increase free testosterone? What the science says
Quick answer
The creator describes a personal protocol used after antibiotic-induced gut dysbiosis, framing gut microbiome restoration and cortisol reduction via sleep and meditation as the primary drivers of a self-reported near-doubling of free testosterone. This falls outside any validated clinical protocol for hypogonadism management, though the interventions themselves are consistent with general lifestyle recommendations sometimes used adjunctively in testosterone optimization. No labs were shown and no clinical diagnosis was mentioned, so the clinical relevance of the reported change cannot be assessed.

Page-specific review note
What this exact clip is really saying
This FormBlends review is specific to "Can you naturally increase free testosterone? What the science says" from OneHot. We read the clip as a TRT social video fact-checks claim about Testosterone, then separate the useful signal from what a short social video cannot prove. The page-specific claim focus is: The creator describes a personal protocol used after antibiotic-induced gut dysbiosis, framing gut microbiome restoration and cortisol reduction via sleep and meditation as the primary drivers of a self-reported near-doubling of free testosterone.
The reason this review is not generic is the source wording and the canonical claim label "trt how to naturally increase free testosterone lastofthenattys." In this clip, the useful excerpt is: "Here's how you can increase your free testosterone levels naturally." That wording changes the review because it points to Testosterone evidence, safety, and patient-fit context, not a one-size-fits-all protocol.
The source trail for this page is checked against Cardiovascular Safety of Testosterone-Replacement Therapy (2023), Testosterone therapy in men with androgen deficiency syndromes: an Endocrine Society clinical practice guideline (2010), and Functional testosterone deficiency in aging men: Clinical impact, diagnostic pathways, and treatment strategies (2026), plus the creator's own wording. Testosterone decisions still need an eligibility review, medication-interaction screen, access check, and quality-control review before anyone treats a social clip as medical advice.

What it helps with
- The creator describes a personal protocol used after antibiotic-induced gut dysbiosis, framing gut microbiome restoration and cortisol reduction via sleep and meditation as the primary drivers of a self-reported near-doubling of free testosterone. This falls outside any validated clinical protocol for hypogonadism management, though the interventions themselves are consistent with general lifestyle recommendations sometimes used adjunctively in testosterone optimization. No labs were shown and no clinical diagnosis was mentioned, so the clinical relevance of the reported change cannot be assessed.
- Leproult and Van Cauter (2011, JAMA) found that just one week of five-hour sleep nights cut daytime testosterone by 10 to 15 percent in healthy young men, making sleep one of the most evidence-backed levers available.
- No human RCT has directly tested whether fermented food consumption raises free testosterone. The gut-androgen connection exists in animal and associative data, but causation has not been established.
What it may miss
- It may not cover eligibility, contraindications, medication interactions, lab history, or dose escalation.
- Compound access, legal status, and product quality still need a separate safety check.
- Social video captions rarely show the full evidence base behind a claim.
Best next step
Compare the claim against a FormBlends guide, safety page, and licensed-provider review before acting.

- SHBG is not simply a testosterone blocker. Low SHBG is associated with metabolic syndrome and cardiovascular risk, so targeting it without clinical indication is not supported by current evidence.
- A self-reported near-doubling of free testosterone from lifestyle changes cannot be attributed to any specific intervention without controlled conditions, baseline labs, and follow-up bloodwork.
- Chronic psychological stress raises cortisol, which suppresses LH release from the pituitary, reducing the hormonal signal that drives testosterone production in the testes.
- Wastyk et al. (2021, Cell) showed high-fermented-food diets increase gut microbiome diversity in humans. Whether that translates to higher androgens remains an open research question.
- Lifestyle optimization including sleep, stress reduction, and diet can support healthy testosterone levels in men with no clinical hypogonadism, but it is not a substitute for evaluation and treatment when true deficiency exists.
Our take · Written by FormBlends editorial team · Reviewed by FormBlends Medical Team · This is not a transcript. It is our independent review of the video above.
What did @onehottrail actually say?
The creator claims they "almost doubled" their free testosterone levels using two main strategies: rebuilding their gut microbiome after antibiotic use, and aggressive stress management through sleep and meditation. Notably, they pushed back on the popular SHBG-lowering approach, arguing it's only worth addressing if levels are genuinely out of range. They listed fermented foods like kimchi, kefir, and kombucha alongside prebiotics from legumes and grains as their gut interventions. For stress, they targeted eight and a half to nine hours of sleep nightly and twice-daily meditation sessions. They were careful to frame this as personal experience, not a universal protocol.
Does the science back this up?
Partially, yes, and more than you might expect. The sleep-testosterone connection is probably the strongest claim here. A well-cited study by Leproult and Van Cauter (2011, JAMA) found that restricting sleep to five hours per night for one week dropped daytime testosterone levels by 10 to 15 percent in young healthy men. That is not trivial. Chronic stress and elevated cortisol are also well-documented suppressors of the hypothalamic-pituitary-gonadal axis, which is the hormonal chain that drives testosterone production.
The gut microbiome angle is where things get murkier. The creator acknowledged this themselves, saying "literature is definitely lacking in this area." They are right. Animal studies have shown microbiome composition can influence steroid hormone metabolism, and some human research links gut dysbiosis to lower androgens, but we do not yet have randomized controlled trials showing that eating kimchi raises your free testosterone. The honest summary: plausible mechanism, thin direct evidence.
What did they get wrong (or right)?
The SHBG framing deserves credit. The "lower your SHBG" trend on fitness TikTok is often presented as a simple lever to pull, but SHBG is not just a testosterone thief. It also protects against certain cancers and cardiovascular risk. Aguilera et al. (2023, Journal of Clinical Endocrinology and Metabolism) confirmed that chronically low SHBG is associated with metabolic dysfunction. The creator's point that you should only worry about it if levels are clinically elevated is reasonable and more nuanced than most of what circulates in this space.
Where the video falls short is the claim of "almost doubling" free testosterone. That is a large effect size for lifestyle interventions alone, and without baseline labs, follow-up labs, and controlling for confounders like diet changes and training volume, it is impossible to attribute that change to any single variable. The story is compelling but the evidence is anecdotal.
What should you actually know?
If your testosterone is genuinely low due to hypogonadism, no amount of kimchi or earlier bedtimes will replace a clinical evaluation. Full stop. Lifestyle optimization works best as a foundation, not a treatment. That said, sleep deprivation and chronic psychological stress are two of the most underestimated suppressors of testosterone in otherwise healthy men, and they are worth taking seriously before assuming you need a prescription.
The gut microbiome research is genuinely interesting and moving fast. Studies like Shin et al. (2019, EBioMedicine) have found associations between specific gut bacterial genera and androgen levels, but associations are not causation. Eating fermented foods and prebiotic fiber is good general health advice regardless of what it does to your testosterone. There is no meaningful downside to the dietary recommendations made here.
If you suspect your testosterone is low, get bloodwork. Free testosterone, total testosterone, SHBG, LH, FSH, and a complete metabolic panel give you an actual baseline. Guessing from symptoms is a losing game.
