The length of time for the expiration date or "best used before" date depends on the type of product, as well as the brand.
Perishable items (such as flax oils or certain probiotics) generally have shorter expiration dates. Although our warehouse is fully air-conditioned, these more fragile items are put in cold storage (freezer or refrigeration unit) for maximum freshness.
Our receiving department does its best to verify and then enter the correct expiration dates for all incoming products. However, discrepancies do occur from time to time. This being said, the exceptionally high turnover at iHerb ensures that our inventory is among the freshest in the industry.
Magnesium is one of the body’s most important minerals. It is required as a cofactor in hundreds of enzymatic processes within cells. It helps maintain normal muscle and nerve function, keeps heart rhythm steady, promotes healthy cardiovascular function, supports a healthy immune system, and keeps bones strong. Magnesium also helps maintain blood sugar and blood pressure levels already within normal range, and it is known to be involved in energy metabolism and protein synthesis.
Magnesium is a major factor in relaxing the smooth muscles within the blood vessels, thereby reducing peripheral vascular resistance and promoting a healthy cardiovascular system. Magnesium also affects circulating levels of norepinephrine and the synthesis of serotonin and nitric oxide.
Magnesium positively influences the bone mineral matrix and its ability to metabolize minerals needed for repair and rebuilding. Scientific literature documents the need for a wide range of minerals, including calcium and magnesium, that are vital to maintaining strong, healthy bones.
Moreover, there is strong evidence that dietary magnesium intake and supplementation improves the metabolic profile. Magnesium has been shown to beneficially impact insulin resistance, serum lipid profiles, inflammation, endothelial dysfunction, oxidative stress and platelet aggregability. Since magnesium is so inexpensive, everyone should consider supplementing with at least 500 mg of magnesium daily. This product provides one of the highest concentrations of elemental magnesium per capsule available on the market.
A review of assimilation studies suggests that the citrate salt of magnesium is the best absorbed into the bloodstream. Magnesium Citrate, however, is comprised of only 16% magnesium, and the typical dose of elemental magnesium is 100 to 350 mg a day. Higher doses of 300 mg to 548 mg daily have been shown to help support healthy blood pressure

I opened the pill and diluted the powder in to water. It dissolved completely and the taste was pleasant acidic citrus. That is how you can the if its pure. I used to use Now Foods pure citrate powder but since they channged it (half a year ago)to trimagnesiumcitrate I stopped using it. Trimagnesiumcitrate has bitter unpleseasant taste. I recommend using this product. Natural calm and other brands that "make" the citrate in hot water by using citric acid and magnesium carbonate give me bad stomach upset and diarrhea.

I think it works well. I take it when I feel mentally or physically fatigued and it seems to lift my energy levels. Everyone should be on Magnesium unless you are permanently on holidays!

I take about 4 or 5 of these caps per day and it does make a difference to any feelings of stress and anxiety. It doesn't irritate my bowels at that dose which is great.

I was told that Magnesium may help in lessening your migraine attacks so I decided to purchase one (combined with B-complex, change of lifestyle) and I really think it helped my migraine a lot. Since my doctor had prescribed LifeExtension supplements to me before, I decided to get Magnesium from them as well. It's affordable and it works!
