When starting any supplement, it’s natural to wonder: Will this cause weight gain or bloating? Fortunately, magnesium glycinate is one of the most gentle forms of magnesium—and it’s very unlikely to cause either.
⚖️ Weight Gain Concerns
There is no evidence that magnesium glycinate causes weight gain. In fact, low magnesium levels are sometimes linked to increased inflammation, insulin resistance, and metabolic issues, which can contribute to weight problems.[1]
- Magnesium plays a role in blood sugar regulation
- It may improve insulin sensitivity and support metabolic health
- It’s often included in weight management and PCOS supplement routines
😣 What About Bloating?
Some forms of magnesium—like magnesium oxide or citrate—can act as laxatives and cause bloating, cramping, or diarrhea.
Magnesium glycinate is different. It’s chelated with glycine, making it much easier on the digestive tract. Most people tolerate it well, even at higher doses.
💊 How to Minimize Any Discomfort
- Start with 100–200mg and increase slowly if needed
- Take it with food to reduce the chance of mild stomach upset
- Choose a high-quality brand without fillers or laxative additives
📌 Bottom Line
No—magnesium glycinate does not cause weight gain. It’s actually supportive of healthy metabolism and digestion. While some people may notice mild bloating when first starting, that’s rare and usually temporary.
