How Long Does It Take for Magnesium Supplements to Start Working?

The Importance of Magnesium for Overall Health

Magnesium is one of the most important minerals for overall health. It plays a role in over 300 biochemical reactions in the body. Getting enough magnesium ensures proper functioning of muscles, nerves, blood sugar control, bone strength, and steady heart rhythm and blood pressure.

Magnesium's Role in the Body

Some of magnesium's key roles include:

• Building and maintaining strong bones and teeth
• Regulating muscle and nerve function
• Supporting energy production and blood sugar control
• Promoting normal blood pressure
• Maintaining a steady heartbeat

Magnesium works together with calcium to support bone health. It also helps nerves communicate with muscles to enable movement and contraction. The mineral activates enzymes needed for energy production and allows insulin to efficiently shuttle blood sugar into cells.

In the cardiovascular system, magnesium prevents spikes in blood pressure and keeps the heart beating steadily. Given its widespread roles, ensuring optimal magnesium status is important for overall health.

Signs of Magnesium Deficiency

Since magnesium is needed for so many vital functions, a deficiency can cause various symptoms including:

• Muscle cramps and spasms
• Abnormal heart rhythms
• Fatigue and weakness
• Trouble sleeping
• Headaches and migraines
• Low bone mineral density
• High blood pressure
• Irritability and anxiety

Individuals with gastrointestinal conditions like celiac disease and Crohn's disease are at higher risk of magnesium deficiency. Older adults, alcoholics, and people with type 2 diabetes also commonly have inadequate magnesium levels.

If you experience any of those symptoms regularly, ask your doctor to check your magnesium levels. A blood test can determine if your stores are lower than normal.

How Magnesium Supplements Can Restore Levels

Taking magnesium supplements can help increase body stores and resolve a deficiency. Magnesium is available in several supplemental forms including:

• Magnesium oxide - inexpensive but not well absorbed
• Magnesium citrate - highly bioavailable and easily absorbed
• Magnesium glycinate - well absorbed and gentle on the stomach
• Magnesium chloride - contains elemental magnesium bound to chloride
• Magnesium threonate - able to cross blood-brain barrier

Magnesium citrate is one of the more popular options because it has high bioavailability and is affordable. Magnesium glycinate is also an excellent choice, especially for those with sensitive stomachs.

Recommended Magnesium Dosage

The recommended dietary allowance (RDA) for magnesium is:

• 310-320 mg per day for women
• 400-420 mg per day for men
• 350-360 mg per day during pregnancy
• 310-320 mg per day while breastfeeding

However, many experts believe the RDA is too low. They recommend getting 400-600 mg per day for optimal health.

The maximum tolerable upper limit is 350 mg of supplemental magnesium per day. With high doses, take magnesium in divided doses throughout the day for better absorption and to minimize side effects.

Magnesium Dosage for Deficiency

If you've been diagnosed with a magnesium deficiency, the dose needed to restore levels depends on its severity. Your doctor can order follow-up blood tests to ensure your levels are being replenished.

For mild deficiency, 200-250 mg of supplemental magnesium per day in addition to dietary intake is usually sufficient. With moderate deficiency, you may need 300-400 mg per day.

For severe deficiency, very high doses up to 1000 mg per day may be prescribed under medical supervision. The goal is to gradually re-establish normal magnesium levels without overdoing it.

When to Expect Effects from Magnesium Supplements

Magnesium supplements take some time to restore body stores. Here is a general timeline of when you may start noticing effects:

• 1-2 weeks: Increased energy, less fatigue. Mild improvement in muscle cramps or twitches.
• 2-4 weeks: Relief from constipation and regularity in bowel movements.
• 4-8 weeks: Improved sleep quality. Decreased symptoms of anxiety or depression.
• 2-3 months: Stronger bones and teeth. Improved blood sugar control.
• 3-6 months: Reduction in blood pressure. Steadier heart rhythm.

Of course, the timing depends on your individual deficiency levels and response to supplementation. With mild deficiency, you may feel energized right away. If severely deficient, it can take 6 months for magnesium stores to be replenished.

Be patient when starting magnesium supplements and stick with it. The benefits for your muscles, nerves, bones, heart, and entire body make it well worth it.

When Effects of Magnesium Kick In

Here is more on when you may start noticing specific effects from magnesium supplements:

• Energy: Magnesium supports energy production in cells. Within 1-2 weeks you may have less fatigue.
• Muscle function: Nerves and muscles require magnesium for contraction. Muscle cramps and spasms should improve in 1-4 weeks.
• Bowel regularity: Magnesium draws water into the intestines and relaxes muscles for bowel movements. Less constipation may occur in 2-4 weeks.
• Sleep: Magnesium promotes calm and relaxation for better sleep. You might sleep better after 4-8 weeks.
• Mood: Magnesium interacts with neurotransmitters that influence mood. Decreased anxiety or depression can happen in the first 1-3 months.
• Bone density: By supporting bone formation, magnesium strengthens bones over 2-3 months.
• Blood pressure: Magnesium prevents spikes in blood pressure. You may see lower readings in 3-6 months.
• Heart rhythm: Normal electrical conduction in the heart relies on magnesium. Steady heartbeat in 3-6 months.

Keep a symptom journal to note changes you experience from magnesium supplements. Share it with your doctor to determine if your dosage needs adjustment.

Signs Magnesium is Working

In addition to timing, these are signs the magnesium supplements are restoring your levels:

• Fewer headaches and migraines
• More regular and complete bowel movements
• Decreased menstrual cramps
• Improved exercise performance and recovery
• Increased bone density on tests
• Better blood sugar control
• Lower blood pressure readings
• Less muscle twitching and tingling

You may also have follow up blood work done after supplementing with magnesium for 3-6 months. This allows your doctor to confirm your levels have been replenished.

Maximizing Magnesium Absorption

To help your body readily absorb and utilize supplemental magnesium, follow these tips:

• Take magnesium with food for better absorption.
• Use citrate, glycinate, or threonate forms for bioavailability.
• Avoid magnesium oxide as it is poorly absorbed.
• Spread doses throughout the day instead of one large dose.
• Pair magnesium with vitamin D for optimal functioning.
• Avoid taking magnesium with calcium as they compete for absorption.
• Consider transdermal magnesium (magnesium oil) for muscle cramps.
• Avoid excessive caffeine and alcohol as they deplete magnesium.

Magnesium is one mineral that you want to make sure your body can access and utilize. Pay close attention to the type of magnesium supplement and how you take it.

Tips to Get the Most from Magnesium Supplements

Follow these tips to maximize absorption and results from magnesium supplementation:

• Citrate, glycinate, threonate forms: Magnesium citrate, magnesium glycinate, and magnesium threonate have excellent bioavailability and are recommended.
• Avoid magnesium oxide: Magnesium oxide is very poorly absorbed, especially at higher doses. Opt for a more bioavailable form.
• Take with meals: Taking magnesium supplements with food improves absorption compared to an empty stomach.
• Divide doses: Spread out your daily magnesium dose instead of taking it all at once for better absorption.
• Pair with vitamin D: Vitamin D helps your body utilize magnesium, so supplement both nutrients together.
• Avoid calcium: High calcium intake interferes with magnesium absorption. Space out doses of each.
• Transdermal magnesium: Magnesium oil applied to skin bypasses the digestive tract and directly replenishes stores.
• Limit caffeine & alcohol: Caffeine and alcohol increase magnesium excretion from the body so avoid excess intake.

Taking these steps allows your body to get the most magnesium possible from supplements for restoring levels.

Potential Side Effects of Magnesium

Magnesium supplements are quite safe for most people when taken at recommended dosages. However, some potential side effects can occur, especially at high doses.

Possible side effects of magnesium supplements include:

• Diarrhea
• Abdominal cramps or discomfort
• Nausea
• Bloating or gas
• Weakness or fatigue
• Dizziness
• Facial flushing or sweating
• Low blood pressure
• Irregular heartbeat

Gastrointestinal distress is the most common side effect as magnesium draws water into the intestines. Start with a low dose and increase gradually to minimize risk of diarrhea.

Slowing magnesium dosage reductions and taking smaller doses spread throughout the day can also help manage side effects. If symptoms persist, consider switching magnesium types or lowering your dose further.

Signs of Excess Magnesium

Be aware of these signs that your magnesium intake from supplements may be too high:

• Diarrhea that persists for multiple days
• Severe abdominal cramping, nausea, or vomiting
• Dizziness, confusion, or disorientation
• Irregular heartbeat, palpitations, or fast heart rate
• Muscle weakness, tremors, or unsteadiness
• Tingling or numbness in the extremities
• Difficulty breathing

Very high amounts of magnesium essentially have a laxative effect by drawing excessive fluid into the intestines. Toxicity is rare but can also affect the cardiovascular system and nervous system.

If you experience multiple or severe side effects, stop taking magnesium supplements and see a doctor immediately. Adjust your dosage based on their recommendations to avoid toxicity.

The Bottom Line

Magnesium supplementation serves many vital functions in the body. However, it does take some time for magnesium levels to be restored before you'll notice the benefits.

Signs like improved energy, muscle function, sleep, and mood often start within 1-2 months. But the full effects on cardiovascular health, blood sugar, and bone density can take 3-6 months as body stores are replenished.

Be patient, stick with it, and give magnesium supplements enough time to work their magic. Pair it with a healthy diet rich in magnesium foods too. With consistency, magnesium can help get your body functioning optimally.
