The muscle is attached to a flat, strong tendon that is connected to the shoulder joint capsule. Along with the deltoid and pectoralis major muscles, the supraspinatus muscle helps initiate horizontal abduction (raising the arms skyward) of the shoulder.
Inositol has a calming effect as it is involved in the production and action of neurotransmitters (chemicals that transmit messages between nerve cells) like serotonin and acetylcholine. People who are depressed have been found to have lower levels of inositol than normal. Inositol has been tested as a treatment for depression, and initial evidence is encouraging. In a small double-blind study those on the supplement who took 12 g of inositol daily for 4 weeks showed significant improvement compared to the placebo group.
I have described much more fully the side effects of this vitamin elsewhere. [24] Inositol hexaniacinate is an ester of inositol and nicotinic acid. Each inositol molecule contains six nicotinic acid molecules. This ester is broken down slowly in the body. It is as effective as nicotinic acid and is almost free of side effects.
