There is no remaining doubt: boosting levels of growth hormone yield some age-preserving/reversing effects.
Growth hormone, produced by the pituitary gland, is responsible for sustaining cell growth, muscle mass, mobilization of fat, and many other aspects of youthfulness. Release of growth hormone is under the influence of many factors, including sleep (most growth hormone release occurs during sleep), exercise, and diet. No surprise, given its potential to reverse many of the phenomena of aging, people have injected growth hormone or pursued strategies that increase its release to obtain age-reversing effects. And, to some degree, there is no question that it works. (It has not been shown to increase longevity, however, an altogether different question.)
We know from experimental observations that oxytocin hugely boosts growth hormone release, increasing levels by 300%. To my knowledge, such observations have not yet been made in humans. But several phenomena point us in the direction of believing that oxytocin boosts growth hormone levels in those of us consuming the L. reuteri yogurt.
These observations include:
- Sleep—Anecdotally, many of us consuming the L. reuteri yogurt experience deep, profound sleep filled with vivid dreams, much as experienced as children. Personally, as a chronic, lifelong insomniac, I now sleep 9 hours per day, often not waking even once during the night, with brightly colored, detailed, wild dreams that I have not experienced to such a degree in something like 50 years. Because growth hormone is produced during sleep, the profound enhancement of sleep suggests that there is more opportunity for growth hormone release.
- Muscle growth—Dramatic increase in muscle mass and strength is a common observation in people consuming the L. reuteri yogurt. Personally, my strength has increased considerably doing lat pulldowns with 200 pounds for 10 repetitions, bench presses with 160 pounds for 10 repetitions, leg presses with 415 pounds for 15 repetitions at age 62.
- Preservation of bone density—There is substantially less deterioration in bone density when L. reuteri is supplemented and oxytocin is boosted, effects that may involve higher levels of growth hormone.
While we need further exploration in humans (we are planning one such human trial), my prediction is that L. reuteri doesn’t just increase levels of growth hormone, but restores youthful levels of growth hormone. Likewise, L. reuteri, yes, increases testosterone, but I think it is more accurate to say that L. reuteri restores youthful levels of testosterone. In other words, you probably cannot overdo these effects, as they are likely self-regulating.
Compare this situation in which we enjoy the phenomena of age reversal to someone who lacks L. reuteri and thereby has lower oxytocin levels, coupled with the growth hormone-inhibiting effects of high blood sugar, high cortisol, and inflammation, especially the inflammation of metabolic endotoxemia resulting from SIBO. (Recall that most overweight/obese people have SIBO with metabolic endotoxemia contributing to insulin resistance, fatty liver, heart disease, and risk for dementia.) This common collection, you can appreciate, is age-accelerating.
You could therefore spend thousands of dollars every month giving yourself injections of growth hormone. Or you could spend a few dollars every month and enjoy a rich, thick, and delicious yogurt rich in tens of billions of CFUs of L. reuteri. Combine this with the benefits of the Wheat Belly lifestyle, and you have a powerful means of extending youth.
