The most gentle forms of magnesium, known for being easy on the stomach and well-absorbed without laxative effects, are Magnesium Glycinate (or diglycinate) and Magnesium Malate, with Glycinate especially favored for relaxation and sleep, while Malate is good for energy and muscle pain. For those with highly sensitive stomachs, topical sprays or oils (like Magnesium Chloride) can bypass the digestive system entirely, though research is still developing on absorption.
Magnesium glycinate – Gentle on the stomach and calming; may help with sleep, stress and anxiety.
The best magnesium supplement for pregnancy often depends on specific needs, with Magnesium Glycinate recommended for sleep/relaxation (gentle on stomach) and Magnesium Citrate for constipation relief due to high absorption, while Magnesium Bisglycinate is highly effective for pregnancy leg cramps, though always consult your doctor before starting any supplement. Magnesium is crucial, but aim for forms with high bioavailability like glycinate or citrate, as less absorbable forms like oxide aren't ideal for correcting deficiencies, and topical options (oils, Epsom salts) are great for cramps.
If you're taking magnesium to help with both anxiety and sleep, the best choice is likely magnesium glycinate or magnesium L-threonate. These formulations combine magnesium with amino acids that may help with relaxation and sleep.
Magnesium oxide is one of the most common and least expensive forms of magnesium for constipation. But there are others, including magnesium citrate or magnesium sulfate (Epsom salts). Make sure you follow the recommended dosage, and give yourself time to be near a bathroom when the medication takes effect.
You can use magnesium glycinate for stress relief, sleep support, and muscle relaxation. Magnesium citrate may be better for constipation relief, but it may cause diarrhea and dehydration.
In general, fiber supplements are the gentlest on your body. These also are called bulk-forming laxatives. Metamucil and Citrucel fall into this category.
However, if you ingest high doses of any magnesium supplement, you might experience side effects, such as diarrhea, gastrointestinal irritation, nausea, vomiting and worse. If too much magnesium builds up in your body, as can happen if you have kidney disease, you can have serious side effects.
Magnesium deficiency symptoms start mild with fatigue, weakness, loss of appetite, nausea, vomiting, and headaches, but progress to more severe issues like muscle cramps/spasms, numbness, tingling, anxiety, insomnia, abnormal heart rhythms, and even seizures, affecting nerve, muscle, and brain function crucial for overall health.
This form of magnesium is easily absorbed without causing digestive upset†. It is gentle on the stomach and less likely to cause diarrhea compared to other forms of magnesium†. Magnesium glycinate is often recommended for general magnesium supplementation†.
Magnesium may play a role in premenstrual syndrome (PMS), PCOS, and perimenopause symptom management. "For most women, I recommend Thorne Magnesium Bisglycinate," says Peterson. "It's a highly bioavailable form that supports relaxation, hormone health, and restful sleep without gastrointestinal side effects."
1. Magnesium glycinate: Best absorbed form, bonded to glycine amino acids, gentle on the stomach, ideal for muscle cramps and sleep support, and considered the safest form with the least side effects.
With Magnesium L-Threonate
Scientists from top-tier universities developed Magnesium L-Threonate, aka “the brain magnesium”, to specifically cross the blood-brain barrier.
Forms of magnesium to avoid or use with caution
Magnesium and Zinc
Researchers have found that high doses of zinc supplements can decrease magnesium absorption and affect magnesium balance in the body, regardless of calcium intake.
Magnesium glycinate, magnesium orotate, and magnesium taurate are especially beneficial for heart health. These forms help regulate heart rhythm, support healthy blood pressure, and provide energy to heart cells.
Magnesium deficiency
For drinks high in magnesium, opt for mineral waters, fruit juices (especially orange, cherry, watermelon), plant-based milks (soy, almond), and homemade concoctions using raw cacao, coconut milk, or magnesium powders mixed with water or smoothies, with hot chocolate (made with raw cacao) and herbal teas (like nettle) also being good choices.
If you're not sure where to begin, magnesium glycinate is an excellent place to start for sleep and anxiety. For sharper thinking or brain-based anxiety, try magnesium L-threonate. And for calming both your mind and body, magnesium taurate offers a gentle, heart-centered approach.
Signs of more severe magnesium toxicity (when your magnesium is too high) may include:
While there are many forms of magnesium available, we often prefer to use magnesium citrate and/or magnesium glycinate. Magnesium citrate is most helpful for people suffering from constipation, while the glycinate form is more useful for conditions like anxiety, insomnia, chronic stress, and inflammatory conditions.
To avoid constipation in Japan, focus on hydration, fiber-rich Japanese foods (seaweed, soy, daikon, fruits/veggies), regular exercise, and routine, while also trying local fiber drinks like Fibe-Mini or Zero Cider and considering traditional remedies like daikon radish soup or herbal supplements like Daikenchuto (TJ-100) if needed.
What empties your bowels in the morning is a combination of your body's natural gastrocolic reflex (stimulated by eating and drinking), high-fiber foods, sufficient fluid intake, and physical activity, with warm liquids (coffee, tea, lemon water) and specific foods like prunes, pears, and whole grains being particularly effective at triggering regularity. Establishing a consistent routine with these elements helps train your body for predictable morning bowel movements.
Increasing the intake of water and fiber is often the first step. Vegetables, fruit (especially prunes), whole-grain breads, and high-fiber cereals are excellent sources of fiber. Bran is an alternative source, although it may cause excessive gas and bloating.
