MSM, also known as methyl sulfonyl methane, is a compound found naturally in foods such as cowâs milk, meat, seafood, fruits and vegetables. MSM is thought to work by contributing sulfur. Itâs found in capsule or tablet forms.
Simply explained, BIA measures the impedance or resistance to the signal as it travels through the water that is found in muscle and fat. The more muscle a person has, the more water their body can hold. The greater the amount of water in a person's body, the easier it is for the current to pass through it. The more fat, the more resistance to the current. BIA is safe and it does not hurt. In fact, the signal used in body fat monitors can not be felt at all either by an adult or child.
In quantitative terms, it is the complex ratio of the voltage to the current in an alternating current (AC) circuit. Impedance extends the concept of resistance to AC circuits, and possesses both magnitude and phase, unlike resistance, which has only magnitude.
