Optimal Magnesium by Seeking Health provides 150 mg of high potency magnesium per vegetarian capsule. Magnesium is an important and abundant mineral naturally present in the body, which acts as a cofactor in hundreds of enzymatic processes and systems. It helps regulate biochemical reactions in the body, including protein synthesis, muscle and nerve function, normal sugar and carbohydrate metabolism and healthy blood circulation. Magnesium is involved in normal muscle relaxation by inhibiting calcium influx and smooth muscle contraction. It is also important for energy production, oxidative phosphorylation, and glycolysis. It contributes to the maintenance and development of healthy bone structure and is needed for the synthesis of DNA, RNA, and glutathione, an important antioxidant.*

Optimal Magnesium contains bioavailable Albion® DiMagnesium Malate and TRAACS® Magnesium Lysinate Glycinate Chelate. Magnesium malate is the combination of magnesium with malic acid, an acid found in vegetables and fruit. The weak bond with magnesium makes this form readily soluble in the body. Malic acid is a key component of several energy production reactions in the body. Highly absorbable and typically well-tolerated, the chelated form of magnesium in this product, magnesium lysinate glycinate, rarely causes adverse gastrointestinal side effects often seen with other forms of magnesium when consumed in higher amounts.*

For a magnesium supplement with added vitamin B6, consider our Magnesium Plus. For a magnesium supplement providing only magnesium malate in a chewable format, consider our Active Magnesium Chewable.

Great for sleep
I always have this at my bedside in case I'm having a difficult time getting to sleep. I usually will take 1-2 capsules and I will be relaxed within just a couple minutes. I sually will drift on to sleep within 15-20 minutes after taking this. It's very helpful for muscle cramps too. Review by Nicole (Posted on 12/17/2017)
Sleep and Muscles
I get twitching muscles regularly. I take Cell Salts but sometimes an extra boost of magnesium will help, and this has! I also take it to help with sleep. Much better quality than what I was taking before. Review by Jessica (Posted on 10/30/2017)
great magnesium
I take this every night as recommended by my doctor. Helps me stay regular, detoxify and calm my nervous system. So glad Seeking Health has this quality product! Review by rebecca (Posted on 6/7/2017)
This product is great. Actually all seeking health products have been great for me. I won't buy my supplements anywhere else. Review by Gina (Posted on 6/3/2017)
Wonderful Product Order ID# 1310089182
I would not be without this product. It has helped me lessen my beta blocker that I take for my MVP. I sleep so much better! Love this product! Review by Amy (Posted on 9/24/2015)
brings muscular comfort
When I am without this product I experience rapid heartbeat and rock hard, sore calf muscles. I supplement with Seeking Health Bone Nutrients,however, I find I still require the extra magnesium. Seeking Health has a life-long customer in me. I trust the quality and purity of the products.I appreciate how quickly they process and ship orders. Thank you. Review by Hope (Posted on 7/18/2014)
I started taking a night dose of Magnesium lately and I've notice improved sleep and better recovery after workouts. This is a great product and I'd recommend it to anyone. The Zinc Carnosine is a great product too! Both boost testosterone with exercise and increased libido which is always a plus :)
Great products. I pretty much only order from Dr. Mercola, Charles Poliquin, and now you.

I love knowing I am taking quality products! Review by LisaB (Posted on 2/20/2013)
Excellent product
I notice when taking this, my blood sugar stays stable longer, less muscle cramps, and I sleep better at night. I have had no side effects, which is hugely important, just good results from taking this. Who would have realized so many issues could be a result of low magnesium.
