Side effects, which also include accelerated heart rate and difficulty breathing, may be more pronounced if you take high doses of GABA without exercising afterward.
Pregnant women and anyone with kidney disorders should not take GABA. Do not take GABA with substances that affect its pathway to the brain. Examples include alcohol and barbiturates. In clinical settings, participants have taken up to 18 grams of GABA, but this doesn't mean you can safely take this — or any — amount daily for long-term use.
Naturally occurring GABA is well studied. Its slows nerve activity in your brain. HGH also boosts muscle growth, strength, and exercise performance, while helping you recover from injury and disease 4 , 7 , 8. Low HGH levels may decrease your quality of life, increase your risk of disease, and make you gain fat 9. Optimal levels are especially important during weight loss, injury recovery, and athletic training 10 , 11 , 12 , Interestingly, your diet and lifestyle choices can significantly affect your HGH levels 6 , The amount of belly fat you carry is directly related to your HGH production 3.
Those with higher levels of belly fat will likely have impaired HGH production and an increased risk of disease. One study observed that those with three times the amount of belly fat as the control group had less than half their amount of HGH Another study monitored the hour release of HGH and found a large decline in those with more abdominal fat.
Interestingly, research suggests that excess body fat affects HGH levels more in men. However, lowering body fat is still key for both genders 15 , After losing a significant amount of weight, their levels returned to normal Belly fat is the most dangerous type of stored fat and linked to many diseases.
Losing belly fat will help optimize your HGH levels and other aspects of your health. Get rid of excess body fat — especially around your belly — to optimize your HGH levels and improve your health. Other studies have found similar effects, with double or triple HGH levels after just 2—3 days of fasting 19 , 20 , However, continuous fasting is not sustainable in the long term.
Intermittent fasting is a more popular dietary approach that limits eating to brief time periods. Multiple methods of intermittent fasting are available. One common approach is a daily 8-hour eating window with a hour fast. Another involves eating only — calories 2 days per week 22 , Intermittent fasting can help optimize HGH levels in two main ways. First, it can help you drop body fat, which directly affects HGH production 24 , 25 , 26 , Research suggests that insulin spikes can disrupt your natural growth hormone production 28 , One study observed large differences in HGH levels on the fasting day compared with the eating day Shorter 12—hour fasts likely help as well, though more research is needed to compare their effects with full-day fasts.
When taken alone, arginine may boost HGH. Though most people tend to use amino acids like arginine alongside exercise, several studies show little or no increase in HGH levels 31 , 32 , However, studies have observed that taking arginine on its own — without any exercise —significantly increases levels of this hormone 32 , One study examined the effects of taking either 45 or mg of arginine per pound or mg per kg of body weight, or around 6—10 or 15—20 grams per day, respectively.
Refined carbs and sugar raise insulin levels the most, so reducing your intake may help optimize growth hormone levels 24 , One study found that healthy people had 3—4 times higher HGH levels than those with diabetes, as well as impaired carb tolerance and insulin function Along with directly affecting insulin levels, excess sugar intake is a key factor in weight gain and obesity, which also affect HGH levels.
