magnesium supplement that you can truly feel working
I’m repurchasing this product for the second time, which already says a lot. I’ve tried different magnesium supplements before, but this one stands out because the formula feels very well absorbed – I actually notice the difference in my body. After taking it regularly, I’ve become much calmer, less anxious in the evenings, and I fall asleep faster and wake up feeling properly rested instead of tired. I also really like that it combines several forms of magnesium in one capsule, so I don’t need to buy and mix different products to get a full-spectrum effect. It’s gentle on my stomach, easy to take, and has become a stable part of my nighttime routine. If you’re looking for a magnesium supplement that you can truly feel working – especially for stress and sleep, this one is definitely worth trying.

Great support for sleep and relaxation
I’ve had a very good experience with this magnesium supplement. I take it at night and it helps me relax, sleep better, and wake up with less muscle tension. I really like that it combines different forms of magnesium, which makes it feel well-rounded and easy on the stomach. The quality is noticeable and the bottle lasts a good amount of time. I would definitely recommend it to anyone looking to support better sleep and overall well-being.

A very good magnesium supplement.
I've tried several magnesium supplements before, and this one from BiOptimizers has been one of the best. It's well-absorbed, doesn't cause me any discomfort, and I really notice the difference in my muscle relaxation and sleep quality. Plus, the formula is high-quality and feels more effective than others I've taken. I recommend it if you're looking for a magnesium supplement that actually works.

Great Magnesium Blend for Calm Nights & Daily Balance
I’ve been using BIOptimizers Magnesium Breakthrough for a few weeks now, and overall it’s been a really solid supplement. I love that it combines 7 different forms of magnesium—it feels more comprehensive than standard magnesium supplements. I noticed a calming effect in the evenings, better quality sleep, and less muscle tension, especially on stressful days. It’s also been gentle on my stomach, which is a big plus since some magnesium formulas can be harsh. I feel more relaxed and focused the next day without feeling groggy. The only reason I’m giving it 4 stars instead of 5 is because I wish the bottle lasted longer—30 capsules goes pretty fast if you’re consistent. Otherwise, it’s a high-quality, well-formulated supplement that I’d definitely recommend if you’re looking for sleep, stress, and cognitive support.

Got this to relax… ended up sleeping like a rock 😴
I was looking for a magnesium supplement that felt more complete and gentle on my body. I’ve tried others before, but most of them either didn’t do much or upset my stomach. First impression: the capsules are easy to swallow and the bottle feels high quality. No weird smell or aftertaste, which I appreciate. I started taking it in the evening, and after a few days I noticed I was feeling more relaxed before bed. My sleep felt deeper and more consistent, especially on nights when my mind usually won’t shut off. What I like most is that it doesn’t feel harsh and doesn’t cause digestive issues for me. It feels balanced rather than overwhelming. The only downside is the price — it’s definitely more expensive than basic magnesium supplements. That said, if you’re looking for a high-quality magnesium and are willing to invest a bit more, this one is worth trying. I would buy it again

Great supplement with a noticeable calming effect — my sleep became deeper and I started falling asleep faster within a few days. I really like that it contains 7 forms of magnesium, which makes it gentle on the stomach compared to other products. Convenient dosage and clear benefits for relaxation and mental focus.

Items were well packed & arrived on time! Expiry date of items is in June 2026 which is alrite but would be better with a later expiry date. Price of item would be more attractive if can be made lower. Overall, I would give a 4-star rating!
