See L-Lysine.

An essential amino acid.  Lysine is particularly important in the synthesis of collagen (important structural protein in bone, connective tissue and skin), as well as the synthesis of l-carnitine.  Supplemental lysine has been shown to enhance intestinal calcium absorption, and may also help reduce the symptoms of herpes simplex and herpes zoster (shingles) outbreaks.

A salt of creatine and taurine, a non-protein amino acid.  According to US Patent #6,861,554, creatine taurinate is “…a stable, non hygroscopic compound endowed with synergistic activity with respect to creatine and taurine”, that can increase glucose disposal.  Creatine taurinate has never been studied w/respect to improvements in mass gains or strength; much less compared to creatine monohydrate, so its effectiveness has yet to be determined.

See Creatine Malate.

See Creatine Malate.

A creatine salt and alternative to creatine monohydrate. Creatine malate is alleged to be more bioavailable as well as more effective than creatine monohydrate, due to “synergy” between creatine and malic acid (an organic acid and Kreb’s Cycle intermediate), but this has not been studied under controlled conditions.

Di-creatine malate and tri-creatine malate are variations on the same theme, with different ratios of creatine to malate (2:1 and 3:1, respectively).

See Paul’s article “Creatine Monohydrate: The BodyBuilding Wonder Supplement?” for information on the benefits of creatine supplementation.

See Melatonin.

Also known as N-acetyl-5-methoxytryptamine.  A hormone produced by the pineal gland.  Melatonin is best known for its role in regulating sleep and circadian rhythms. Melatonin also acts as an antioxidant, and—interestingly enough—may increase the exercise-induced production of growth hormone when taken in supplemental form.

See ”Melatonin Information and Side Effects” for more information.

See Muira Puama.

Also called “potency wood”. An herbal preparation from Ptychopetalum olacoides Bentham – a South American tree. Bark/root extracts are often included in various male enhancement supplements for their reputed aphrodisiac effects. Animal experiments suggest it may have antidepressant and antioxidant activities.
