The Benefits Of Life Extension Magnesium

Bone And Joint Support

Magnesium is a natural calcium blocker, which helps your muscles relax after contractions. This is especially helpful for muscle aches and pains and for workout recovery support. When magnesium levels are low, our muscles react by contracting too much and causing muscle spasms. Magnesium can help prevent those spasms. Magnesium deficiency can also cause bone disorders like osteoporosis, so keeping levels within the normal range is essential for bone, muscle, and joint health and support.

Supports Heart Health

Low magnesium levels in the body have also been linked with heart disease later on in life. Low levels may cause arterial plaque build-up, high blood pressure, arterial hardening, and high cholesterol. Magnesium has been proven to help lower high blood pressure and helps support good heart health.

Supports Nervous System Function

Magnesium also plays a role in nerve transmission and neuromuscular conduction. Many forms of magnesium are often used to relax and calm the nervous system, leading to a decrease in stress and anxiety and even helps promote better sleep quality. Magnesium is also proactive against too much neurological excitation. This excitation can lead to neuron cell death, which can cause various neurological disorders. Magnesium is often deemed the relaxation mineral and often causes neurotransmitters like GABA to increase, leading to enhanced feelings of calmness.

Life Extension Magnesium Caps Ingredients

Life Extension Magnesium has four different forms of magnesium: magnesium oxide, magnesium citrate, magnesium succinate, and TRAACS® magnesium chelate. These forms make this product one of the most well-rounded magnesium supplements on the market. Although many magnesium forms differ in their specific benefits, this magnesium supplement is great for bone and muscle health/support, nervous system functioning, reducing inflammation in the body, and supporting heart health.

Magnesium oxide is specifically beneficial for treating indigestion and digestive issues like constipation. It has more laxative effects and may help reduce acid build-up in the stomach. Magnesium citrate also has a laxative effect and is often used to treat constipation. It is essentially a saline laxative. Magnesium succinate is often used to support energy metabolism and may even help treat and prevent diabetes.

Finally, magnesium chelate is a form of magnesium that is most readily absorbed and bioavailable in the body. It helps support healthy and normal magnesium levels in the body and helps correct low levels. Magnesium chelate is also quite beneficial for relaxation and providing better quality sleep.
