No measurable effects were observed in athletic performance or in levels of testosterone and cortisol. [3] Consumption of 5-methyl-7-methoxyisoflavone can produce false positive results in urinary tests for cannabinoid use. [4] [5]
4-Methyl-2,4-bis(4-hydroxyphenyl)pent-1-ene (MBP) is a metabolite of bisphenol A (BPA). [1] MBP has potent estrogenic activity in vitro and in vivo , up to thousandfold stronger than BPA. [ 2 ] It may also play a role in neuronal cell apoptosis [ 3 ] and may increase risk for several forms of cancer.
Another reported side effect of SAM is insomnia; therefore, the supplement is often taken in the morning. Other reports of mild side effects include lack of appetite, constipation, nausea, dry mouth, sweating, and anxiety/nervousness, but in placebo-controlled studies, these side effects occur at about the same incidence in the placebo groups.
β-Hydroxy β-methylbutyric acid [note 1] (HMB), otherwise known as its conjugate base, β-hydroxy β-methylbutyrate, is a naturally produced substance in humans that is used as a dietary supplement and as an ingredient in certain medical foods that are intended to promote wound healing and provide nutritional support for people with muscle wasting due to cancer or HIV/AIDS.
To account for this effect, the protein contains a self-reactivation mechanism, a reductive methylation process that uses S-adenosylmethionine as a distinct methyl donor. In humans, the enzyme is reduced in this process by methionine synthase reductase (MTRR), which consists of flavodoxin-like and ferrodoxin-NADP+ oxidoreductase (FNR)-like ...
It is also known by several other names including methyl sulfone and (especially in alternative medicine) methylsulfonylmethane (MSM). [4] This colorless solid features the sulfonyl functional group and is the simplest of the sulfones. It is relatively inert chemically and is able to resist decomposition at elevated temperatures.
Melatonin appears to cause very few side effects as tested in the short term, up to three months, at low doses. [ clarification needed ] [ dubious – discuss ] Two systematic reviews found no adverse effects of exogenous melatonin in several clinical trials, and comparative trials found the adverse effects headaches, dizziness, nausea, and ...
α-Methyl-p-tyrosine (AMPT), or simply α-methyltyrosine, also known in its chiral 2-(S) form as metirosine, is a tyrosine hydroxylase enzyme inhibitor and is therefore a drug involved in inhibiting the catecholamine biosynthetic pathway. [1]
