Glandular supplements are gaining traction once again among fitness enthusiasts, particularly bodybuilders, as a natural alternative to steroids. With claims of significant benefits without the adverse effects associated with steroids, it's worth exploring whether these supplements are as effective as touted or if they're just another passing trend in the supplement industry.
Glandular therapy involves the consumption of animal glands and organs, based on the premise that like supports like—meaning that consuming specific glandular tissues could enhance the function of the corresponding organs in humans. This concept, which saw its peak popularity in the late 70s and early 80s, suggests that intrinsic factors within glandular tissues could specifically target and improve the function of similar tissues in the body.
Originally popular several decades ago, glandular supplements fell out of favor as more scientifically backed supplements took precedence. However, with increasing scrutiny and legal issues surrounding anabolic steroids, some bodybuilders and athletes are revisiting glandulars as a safer alternative. Advertisements and anecdotal endorsements in fitness publications have played a significant role in their resurgence.
The theory behind glandular therapy is intriguing yet controversial. Proponents argue that consuming organ-specific tissues—such as liver to support liver health or brain tissue to enhance cognitive functions—provides specialized nutrients that directly benefit those organs. However, scientific evidence supporting these claims is sparse and often anecdotal.
One of the more famous studies related to the concept of "like supports like" was conducted in 1960 by researchers Reva Kimble, Barbara Humphries, and James McConnell. They experimented with planarians (flatworms), demonstrating that conditioned behaviors could be transferred through consumption of trained flatworms. While fascinating, extrapolating these findings to humans is scientifically unreliable due to vast differences in physiology and complexity between humans and flatworms.
Despite the historical intrigue, no substantial scientific research has conclusively proven that glandular tissues can enhance organ and gland functions in humans beyond their basic nutritional content (vitamins, minerals, and proteins). Furthermore, the specific intrinsic factors purported to be in glandular tissues have yet to be scientifically identified or characterized.
Many bodybuilders claim that glandular supplements provide anabolic effects by naturally boosting the body's hormone production. Commonly consumed glands include liver, thymus, heart, kidney, and more exotic options like pituitary and adrenal glands. However, the effectiveness and safety of these practices remain under-researched and largely based on personal testimonies rather than empirical evidence.
Critics argue that the bodybuilding community's interest in glandulars is driven more by the desire for quick physical enhancements rather than long-term health benefits. The lack of rigorous scientific validation and the reliance on anecdotal evidence make glandular supplements a controversial topic in sports nutrition.
While glandular supplements continue to intrigue with their historical roots and bold claims, the lack of definitive scientific evidence makes them a questionable choice for those seeking reliable and safe nutritional supplements. As with any supplement, individuals considering glandulars should consult healthcare professionals and consider the current scientific landscape. Further research is essential to validate or refute the efficacy of glandular therapy in enhancing human organ and gland function.
