Lithium supplements are available Over The Counter, but know that the dose these researchers are describing appears to be under 100 mg a day.
It appears a 300 mg dose is given to bipolar patients, but note the dose is very close to a dangerous level, otherwise, so keep the dose low.
“It appears a 300 mg dose is given to bipolar patients”
That’s considered the minimum therapeutic dose, the usual dose varies between 300-900 mg. They really go by the blood levels since people excrete it at different rates.
Why use Lithium carbonate, use Lithium orotate, it is not dangerous.
