What customers say

Customers generally praise Source Naturals Magnesium Malate for its high quality and effectiveness in improving muscle relaxation, energy levels, and sleep quality. Many users appreciate the easy-to-swallow gelatin capsules that are gentle on the stomach, with no adverse effects reported by those sensitive to supplements. The product is noted for its beneficial impact on muscle pain, joint discomfort, and anxiety reduction. It is often recommended for conditions like fibromyalgia and chronic fatigue. The generous bottle size offers good value with 100 capsules per bottle. While most reviews are positive, a few customers did not experience the desired effects such as weight loss or found it made them sleepy. Overall, the product is well-received for its quality ingredients and reliable performance.

*This* form of magnesium is much easier on my stomach. Other forms also help with pain and cramping (muscles, menstrual, etc.) as well as magnesium malate, but for me the others came at a cost that I hated to pay--bathroom emergencies. Magnesium malate helps with sleep, relaxation, fibromyalgic pain. Take it apart from your calcium supplements--they compete for the same receptor sites in the body. This is a great brand and a great price.

This one has been a game-changer for my energy and digestion! Magnesium Malate gives a smoother, more sustained effect compared to other forms. I feel less fatigued and my gut stays calmer — which is a huge deal for me. The capsules are medium-sized and easy to take. Source Naturals keeps their formulas clean and efficient, which I really appreciate. The bottle is big and lasts for ages — great value for money. It’s one of those supplements that quietly supports everything from muscles to mood. Total win!

Source Naturals, Magnesium Malate

Verified purchase

"I recommend this supplement. The easy absorption and lack of taste make it incredibly convenient. The quality, size, and dosage are spot-on for boosting immunity, especially for those who have a busy life. The packaging is great, and the dosage is perfect for positive effects on the body. The ingredients are superior compared to other products I’ve tried. I like it so much that I bought two more for my family!"

Everyone needs Magnesium!

Verified purchase

My doctor recommended that I take this to suppliment to help support my heart, nerves, muscles & joints. Our food today is lacking in this important mineral and I trust this brand even though it’s a higher price point I want to make sure I’m getting good ingredients and quality so it’s worth it to me. No bad tastes or side effects I would recommend!

Magnesium malate

Verified purchase

I’ve been using magnesium malate for a couple of weeks now, mostly in the evening after work. I usually take it when my muscle feel tired or when my joints start to ache a bit after long day. What I really like is how it helps with my sleep. I’m not saying it knocks me out, but I feel more relaxed and fall asleep easier than before. Also noticed my muscle recovery feels better, less stiffness in the morning which is big plus for me. The quality seems very good, capsules are easy to swallow and the size is not too big, so no problem there. I also like that it doesn’t upset my stomach, which I had with some other magnesium before. For my overall health, it feels like a solid support supplement. Not a miracle, but something that реально works in everyday life. Good for joint comfort, better sleep and just feeling more balanced. Honestly, I’m happy with it and will keep using.

I have a sever amount of muscle and joint pain due to chronic illness (long-covid related). This is the only magnesium supplement that actually makes a noticeable difference in lessening that pain (I’ve tried many others). Magnesium Malate is a huge win for me, I’ve been taking this for about a year now. I prefer this capsule size, as the others from this brand are too big and hard to swallow. The full recommended dose is 6 capsules; I take 4 capsules (2 in morning, 2 at night), and that seems to work best for me. I haven’t tried any other brands, but I’ve always been a fan of Source Naturals quality. Would definitely recommend if you think it might help your chronic illness.
