The Magnesium-Hair Loss Mystery: Unraveling The Truth About Magnesium Oxide's Laxative Effect

Magnesium is an essential mineral that plays a vital role in various bodily functions. However, excessive intake can lead to hair loss. While magnesium oxide is commonly used as a laxative, its link to hair loss is primarily associated with its potential to disrupt the absorption of other essential minerals, such as zinc and iron, which are crucial for hair growth. The laxative effect of magnesium oxide can also lead to dehydration, negatively impacting hair health. Additionally, high doses of magnesium oxide may cause digestive side effects like bloating and diarrhea, which could indirectly affect hair health. However, the direct connection between magnesium oxide's laxative effect and hair loss requires further exploration.

Magnesium oxide is a supplement used to treat constipation and migraines

Magnesium oxide is a supplement that can be used to treat constipation and migraines. It is one of the most common forms of magnesium sold as a supplement, either on its own or in combination with other nutrients.

Magnesium is a mineral that plays a crucial role in various bodily functions, including blood sugar regulation, nerve function, energy production, and DNA synthesis. It is found in many foods, such as nuts, leafy green vegetables, and whole grains, but can also be taken as a dietary supplement.

When it comes to treating constipation, magnesium oxide has a laxative effect. It draws water into the intestines, softening stools and stimulating bowel movements. It is also used to treat opioid-induced constipation and improve functional constipation in children. However, it is important to note that while magnesium oxide is generally safe, taking large amounts over long periods can lead to high blood magnesium levels, or hypermagnesemia, which is a serious and potentially fatal condition.

In terms of migraine treatment, studies have found that people who suffer from migraines tend to have lower levels of magnesium than those who don't. Magnesium is believed to block signals in the brain that lead to migraines and may also reduce the frequency and severity of migraine attacks. It is thought to be especially effective in treating migraines with aura, or changes in vision and other senses.

While magnesium oxide is a popular and effective supplement for treating constipation and migraines, it is important to consult a healthcare professional before taking it to ensure it is safe and appropriate for your individual needs.

It may also help lower blood pressure and blood sugar levels

Magnesium oxide is a supplement often used to treat migraines and constipation. It may also offer other health benefits, such as lowering blood pressure and blood sugar levels.

Lowering Blood Pressure

Magnesium oxide supplements have been shown to reduce elevated blood pressure levels. A 2018 study involving 48 people with high blood pressure found that treatment with 300 mg of magnesium oxide per day for one month significantly decreased both systolic and diastolic blood pressure. Researchers suggest that the supplement may achieve this by decreasing cellular calcium levels, which in turn relaxes smooth muscle cells and widens blood vessels.

Lowering Blood Sugar Levels

Magnesium oxide supplements may also help lower blood sugar levels in people with diabetes. For example, supplements containing magnesium oxide and zinc have been shown to lower blood sugar levels in people with type 1 diabetes, type 2 diabetes, and gestational diabetes. In a 2015 study, 70 women with gestational diabetes who supplemented with either 250 mg of magnesium oxide or a placebo daily for six weeks showed significantly improved blood sugar levels in the magnesium oxide group.

Magnesium is important for healthy hair growth

Magnesium is an essential mineral that plays a vital role in healthy hair growth. It is involved in over 300 enzymatic reactions in the body, including protein synthesis and energy production. A deficiency in magnesium can lead to hair loss, thinning, and slow hair growth, so maintaining adequate levels of this mineral is crucial for supporting healthy hair.

Magnesium is necessary for proper circulation, ensuring that the scalp receives sufficient blood flow to nourish the hair follicles. It also helps to keep hair follicles anchored in the scalp by strengthening the keratin structures in the hair shaft. When magnesium levels are low, the hair follicles can become loose and fall out more easily.

Additionally, magnesium plays a role in hormone balance. It helps regulate hormones such as testosterone and DHT (dihydrotestosterone), which can contribute to hair loss when imbalanced. Magnesium also helps prevent scalp calcium buildup, which can block pores and lead to hair loss. By reducing calcium levels on the scalp, magnesium improves circulation and stimulates hair growth.

Magnesium is also important for protein synthesis, which is essential for hair growth as hair is primarily composed of a type of protein called keratin. A deficiency in magnesium can disrupt protein synthesis, hindering hair growth. Furthermore, magnesium contributes to cell division, growth, and maturation, as well as immunological responses, all of which are important for healthy hair.

While excessive intake of magnesium supplements can lead to gastrointestinal issues and, in rare cases, hair loss, it is important to note that magnesium deficiency is much more common. Ensuring adequate magnesium intake through a balanced diet or supplements can promote healthy hair growth and reduce the risk of hair loss.

Excess magnesium can cause hair loss by disrupting the absorption of other essential minerals

While magnesium is an important mineral that plays a vital role in various bodily functions, an excess of it can disrupt the balance and lead to unwanted side effects, including hair loss. This is because high levels of magnesium can interfere with the absorption of other essential minerals like zinc, iron, and calcium, which are crucial for hair growth.

Magnesium is a crucial co-factor in the production of enzymes necessary for protein synthesis and DNA repair, which are essential for hair growth. However, consuming excessive amounts of magnesium can disrupt the delicate balance of minerals in the body, leading to mineral imbalances and hindering the proper absorption and utilization of other essential nutrients.

For example, magnesium toxicity, though rare, can cause a range of symptoms, including hair loss, as it can disrupt the balance of minerals and vitamins in the body, leading to nutritional imbalances that can affect hair follicle health. Additionally, excessive intake of magnesium can cause gastrointestinal disturbances, such as diarrhea and abdominal cramping, which can lead to dehydration, making the hair brittle, dry, and more prone to breakage.

Furthermore, an excess of magnesium can interfere with the absorption of iron, a deficiency of which is a known cause of hair loss. It is important to note that these cases of hair loss due to excess magnesium are typically associated with extremely high doses of magnesium and not with regular dietary intake.

To maintain healthy hair growth and overall well-being, it is crucial to follow the recommended dietary allowances (RDA) for magnesium: around 400-420 mg per day for adult males and approximately 310-320 mg per day for adult females. It is best to obtain magnesium from dietary sources such as leafy green vegetables, whole grains, nuts, seeds, and legumes, rather than relying solely on supplements.

Magnesium oxide has a low bioavailability compared to other forms of magnesium

Magnesium oxide is an inorganic salt of magnesium formed with ions of magnesium and oxygen. It is one of the most common forms of magnesium sold as a supplement, either on its own or in combination with other nutrients.

Compared to other forms of magnesium, magnesium oxide may be less effective at raising magnesium levels in the body. This is because it has a low solubility rate, making it less bioavailable. In other words, it is not as easily absorbed by the intestines as other forms of magnesium. As a result, magnesium oxide may lead to digestive side effects such as diarrhoea.

A 2017 rat study found that only 15% of orally administered magnesium oxide was absorbed, while 85% was excreted in faeces. This is supported by older research, which suggests the absorption rate is even lower in humans.

In contrast, other forms of magnesium such as magnesium citrate, magnesium acetyl taurate, magnesium malate, and magnesium glycinate have high absorption rates and are more effective at increasing magnesium levels in the body.

However, despite its low bioavailability, magnesium oxide has been shown to offer several health benefits. It is commonly used to treat medical conditions like chronic constipation, as it has a strong laxative effect. It may also help to reduce blood pressure and blood sugar levels, as well as relieve headaches and reduce stress and anxiety in certain populations.
