A powder can fit into a drink you already make. A capsule can be easier when you’re out the door. If you’re shopping for magnesium, start with the format you’ll actually use, then read the label to see what you’re getting.
Which type of magnesium would I choose?
Glycinate is where I’d start for an evening drink. When I want a fizzy mix and bowel regularity is on my mind, I like Natural Vitality CALM. In the original powder, magnesium carbonate and citric acid form magnesium citrate when mixed with water. Citrate can help keep bowel movements moving by holding water in the stool. It can also loosen stools more than you want, so follow the label. How magnesium citrate works
- Glycinate or bisglycinate binds magnesium to glycine. This is the form in the three picks below.
- Citrate is a soluble form you’ll find in drink mixes and capsules. Magnesium citrate is also available in products labeled for occasional constipation.
- Chloride, lactate and aspartate are other oral forms. Like citrate, they tend to be better absorbed than oxide in small studies.
- Oxide, carbonate and hydroxide show up in supplements or digestive products. Oxide and hydroxide are used in some antacids and laxatives. Carbonate is one of the starting ingredients in original CALM powder.
- Malate, L-threonate, taurate and orotate are specialty forms. Malate is often sold in muscle and energy formulas, and L-threonate is the one you’ll often see in products marketed for memory.
- Gluconate, glycerophosphate, pidolate and lysinate are less common names you may see on labels, including in blends.
- Sulfate is the form in Epsom salt. Check the label for intended use, especially with bath products.
When you compare products, look for elemental magnesium per serving on the Supplement Facts panel. That number tells you how much magnesium you’re getting. NIH magnesium guide · Review of oral magnesium forms
Compare three ways to take magnesium glycinate
- Trace Minerals Magnesium Glycinate Powder. I like having flavored options. If an evening drink sounds better than swallowing a capsule, this is the one I’d look at first. I’d pick a flavor that goes with something I already enjoy, like a fruity powder stirred into cold water with a splash of juice. See Trace Minerals’ stick packs
- Thorne Magnesium Bisglycinate powder. A mix-in if you like making an evening drink. The label lists 200 mg of elemental magnesium per scoop. Compare the flavor and sweetener with what you already drink. Shop Thorne
- Pure Encapsulations Magnesium (Glycinate) capsules. A portable option if you prefer to skip mixing and measuring. Compare the elemental amount per capsule and the number of capsules in a serving. Open the Guided Prana Fullscript dispensary
Magnesium helps muscles contract and nerves communicate. If sleep is what brought you here, one four-week trial found a small improvement in self-reported insomnia symptoms in adults who reported poor sleep. The researchers used a different product and dose from the ones above. NIH magnesium guide · Sleep trial
If you already take a multivitamin or another magnesium product, compare the total across labels. Check with a clinician or pharmacist before supplementing if you have kidney disease or take a medication that can interact with magnesium. NIH safety guidance
Make it fit the way you eat
I take “let food be thy medicine” as an invitation to make nourishment easier and more enjoyable. When a supplement fits your care plan, that same idea can apply to how you take it. For someone with ARFID or other eating difficulties, taste, texture, and predictability can matter a lot. That’s what I like about flavored powders. You can start with a drink you already look forward to and choose a flavor that belongs in it. If you love a tart mocktail, try a berry-flavored powder with cold water, a splash of cranberry juice, and lime. If you’re sensitive to texture, stir until the powder dissolves and use a drink with a texture you already enjoy. Supplements can support an individualized nutrition plan. Meals and eating-disorder care still matter. About ARFID and sensory preferences
