What customers say
Customers generally appreciate the high quality and effectiveness of this magnesium supplement. Many users report improved sleep, muscle relaxation, and overall well-being after incorporating it into their routines. The product is praised for its easy application, thanks to the included dropper that allows precise dosage measurement. However, the taste is a common point of contention; while some find it palatable or easily masked with juice, others struggle with its bitterness or saltiness. The packaging in a brown glass bottle is well-received for its convenience and quality. Users also value that it contains no fillers or additives and is vegan-friendly. Despite some negative feedback on taste, most customers are satisfied with the benefits and plan to repurchase.

Liquid Magnesium That Really Helps You Relax
Verified purchase
I’ve been using Sunwarrior Magnesium Liquid for a few weeks and I’m genuinely pleased with the results. I mix the recommended dose into water before bed, and my sleep has improved—falling asleep faster and waking up feeling more refreshed. It also helps ease muscle tension after a long day. The taste is quite strong and salty (because it’s a concentrated seawater mineral complex), but manageable if you dilute or mix it with juice. Overall, clean ingredients, effective relaxation, and I’ll continue using it as part of my nightly routine.

Great quality!
Verified purchase
I fall asleep much easier and I'm sleeping longer and better after I started taking this. I think my joints and muscles are more relaxed. I don't mind the taste and I like that the ingredients are clean. Good size, it last for a good time but still not too big to bring with me. Good chooice of magnesium/mineral supplement!

Helps with sleep and muscle relaxation
Verified purchase
Clean ingredients and superb quality, the nights when I take it I sleep better, its effect is noticeable. It’s a concentrated seawater mineral complex. The taste is bitter, I put it in small amount of water and have another cup of water ready to drink right after it to wash away the taste. Contains 28 servings.

Good product
Verified purchase
I bought this from sale, I think it is a quality product, but I'm not a big fan of taking it in my drink because I feel that metallic taste, so I prefer capsules. But I guess the absorption is better and I could put some drops in my water bottle and drink it during the day.

Good product
Verified purchase
It improves in sleep, relaxation, and muscle function. Its high bioavailability and natural sourcing from ancient inland sea deposits are key features. The most common complaint is the strong, metallic, or salty taste that requires mixing with juice or other beverages to mask.

Best liquid magnesium!
Verified purchase
Most important for me was the taste and I am happy that it is not strong enough to be terrible. I love the quality of Sunwarrior products so I had to try this supplement since I know ingredients are great quality. I felt the benefits on my joints, muscles and quality of sleep almost instantly. Side note, love their packaging color 🤓 overall highly recommend.

Daily Staple
Verified purchase
I recently tried Sunwarrior Magnesium, and I’m very impressed. The powder mixes easily with water and has a pleasant taste. I’ve noticed a significant improvement in my sleep quality and muscle recovery after workouts. It’s gentle on the stomach, which is a big plus. Overall, Sunwarrior Magnesium has become a staple in my daily supplement routine.

Not so bad but I'll stick to the tablets for now
Verified purchase
The taste is too salty with a spicy aftertaste if it's consumed undiluted but it's potable when it's mixed with a glass of water. I'll probably continue on the tablets in the future.

I have not tried having it during the day but it is very effective if taken just before bedtime . It’s relaxing and I fall asleep 10-20 mins after taking .
