Building good bones starts early. By age 20, we’ve acquired as much as 90% of our peak bone mass. In most women, bones reach their maximum strength and density between about age 20 and 30.
From then on, bone strength and density start to decline. It’s a slow process at first, but it gets kick-started by menopause in women. The stronger your bones are to start with, the more likely it is that you’ll be able to reduce your risks for osteoporosis later in life.
A lot of things can...
There is limited research to back up these claims.
Some women take L-tryptophan supplements to try to ease mood swings due to premenstrual syndrome (PMS), also called premenstrual dysphoric disorder (PMDD). The theory is that these conditions may be linked to a problem with serotonin processing in the body, and that L-tryptophan could help that. However, there is little evidence to show this really works.
Early research in people hints that L-tryptophan supplements may be helpful for:
The amount of L-tryptophan in these foods is small compared to supplements.
What are the risks of taking L-tryptophan?
L-tryptophan has been linked to a dangerous, even deadly condition called eosinophilia-myalgia syndrome (EMS). The FDA recalled tryptophan supplements in 1989 after tens of thousands of people who took them became sick, and some died. EMS causes sudden and severe muscle pain, nerve damage, skin changes, and other debilitating symptoms. Doctors saw a lot fewer people with EMS after the ban. Some research suggests the sickness was due to contaminants that got into the supplements during manufacturing in a factory in Japan.
