Black sesame seeds as testosterone booster: the TikTok claim

What did @gurpreetsanghera actually say?

Honestly, this is a difficult video to fact-check because the transcript is largely incoherent. The caption tells us the creator intended to discuss black sesame seeds (kala til) as a testosterone booster, drawing on their self-described 11 years of experience in Spain. But the actual spoken content that was captured reads as fragmented and largely nonsensical, with references to "muscles recovery," "body to power," and storing "the body of our hands." The only coherent thread is the suggestion that black sesame seeds are not "a special pill" or "personal pill," which may be an attempt to position them as a natural, accessible alternative to pharmaceutical interventions. That framing is worth examining, because the gap between what food can do and what TRT does is significant.

Given the video is categorized under TRT and hormone optimization, the implicit claim seems to be that black sesame seeds can meaningfully raise testosterone levels. That is the claim we will assess here.

Does the science back this up?

The short answer: barely, and not in the way the caption implies. There is some preliminary animal and in vitro research on sesame lignans and their potential hormonal effects, but human evidence for testosterone-boosting effects is thin and inconsistent.

Sesame seeds contain lignans, particularly sesamin and sesamolin, which have been studied for their antioxidant properties. One small human study by Barbosa et al. (2017, Journal of the International Society of Sports Nutrition) found that sesame supplementation in male athletes showed modest improvements in some hormonal markers over 28 days, but the testosterone effect sizes were small and the sample size was just 22 men. Another study by Farahmand et al. (2010, International Journal of Sport Nutrition and Exercise Metabolism) found sesame supplementation increased testosterone and LH in male strength athletes, but again, tiny sample, no long-term follow-up, and no placebo-controlled replication since. Animal studies in rats have shown sesamin may inhibit the conversion of androgens to estrogens, which sounds promising on paper but translating rodent endocrinology to human clinical outcomes is a leap most endocrinologists will not make without better data.

Black sesame specifically is richer in anthocyanins than white sesame, but there is no direct clinical trial showing black sesame outperforms white sesame for testosterone.

What did they get wrong (or right)?

Credit where it is due: framing black sesame as "not a special pill" is technically correct. It is a food, not a regulated pharmaceutical, and presenting it without dosing claims or disease cure language is at least responsible by food influencer standards. If the creator genuinely meant to say this is a dietary addition worth exploring rather than a TRT replacement, that is a defensible position.

What is wrong, or at minimum misleading, is the implicit categorization of this content under TRT. Placing a discussion of sesame seeds into a hormone optimization framework sets audience expectations that a food can replicate or substitute for medical testosterone therapy. It cannot. Men with clinically diagnosed hypogonadism, confirmed by serum total testosterone below 300 ng/dL on two morning measurements per Endocrine Society guidelines, are not going to restore physiological testosterone levels by adding sesame seeds to their diet. Suggesting otherwise, even loosely, does real harm to people who may delay seeking actual medical evaluation.

The transcript also references "30 muscles recovery" and "body to power" in ways that suggest performance benefits beyond what the evidence supports for any single food.

What should you actually know?

Black sesame seeds are genuinely nutritious. They contain zinc, magnesium, and healthy fats, all of which support baseline hormonal health when someone is deficient in them. Zinc deficiency specifically is associated with lower testosterone (Prasad et al., 1996, Nutrition), so eating zinc-rich foods matters if your diet is poor. But this is very different from saying sesame seeds boost testosterone in men who are already adequately nourished.

If you are watching content categorized under TRT because you are concerned about low testosterone symptoms, such as fatigue, low libido, or loss of muscle mass, the right first step is a blood test through a licensed provider, not a food swap. Testosterone replacement therapy, when clinically indicated, involves FDA-regulated medications with established pharmacokinetics. No food has been shown in large-scale trials to replicate those effects. Regulated telehealth platforms can order appropriate labs and evaluate whether TRT or lifestyle changes are the right path for your specific situation. A sesame seed, however nutritious, is not a diagnostic workup.

Our overall rating

The core claim, that black sesame seeds can function as a testosterone booster, is mostly unverifiable with current human evidence. The small studies that exist show modest, inconsistent effects in specific athletic populations. The framing under a TRT category overstates the clinical relevance. Eat sesame seeds if you enjoy them. Do not eat them expecting hormonal therapy.
