Magnesium is a mineral that is critical for energy production and metabolism, muscle contraction, nerve impulse transmission and bone mineralization. It is a required cofactor for an estimated 300 enzymes. Among the reactions catalyzed by these enzymes are fatty acid synthesis, protein synthesis, and glucose metabolism. Magnesium status is also important for regulation of calcium balance through its effects on the parathyroid gland. NOW Magnesium Citrate Pure Powder is a highly bioavailable form of magnesium and contains no excipients or fillers.

Rated 5 out of 5 by from Happy This is my first order with Swanson. I usually order this product from another company who was out of stock. Your price was good as was the shipping but the best part was I received the order within 2 days. Thank ou

Rated 5 out of 5 by from Helpful I take this morning and evening, stirred into a small glass of kombucha. That way it tastes fine and it does what I need it to. It's not as handy as taking capsules, but I use this because it's a little cheaper and there are no filler ingredients.

Rated 5 out of 5 by from Love it, been using it for years I have been taking the Now brand magnesium citrate for years. It relaxes my muscles at night, helps me sleep and helps with the 'go' in the morning. It makes me drowsy so I only take it at night. Stir briskly and drink quickly, then rinse out your cup or you will have very hard residue to scrub out of the bottom when it dries. It does dissolve better if it's in lukewarm water, but I think it tastes horrid this way, so I drink it fast in cold water, about half a teaspoon.

Rated 5 out of 5 by from Calm comparisons Just thought I'd let people know that comparing this to Calm is a bit silly... this is trimagnesium dicitrate... (Magnesium Citrate (3:2), not Magnesium Citrate (1:1).) Obviously it's solubility will not be as great but it's a lot more magnesium by weight (~42.6% more than Magnesium Citrate (1:1).) Excellent product at a great price. Thanks Swanson!

Rated 3 out of 5 by from mixed feelings about this type of supplement This is a good product for what it is, (magnesium citrate) but i tend to wonder if i should be taking separate mg but just stick to a mineral supplement that has all the minerals or at least most of them. Too many minerals can create a burden for the kidneys. It does help with sleep.

Rated 5 out of 5 by from The best of everything GREAT magnesium product! Citrus-y tart, sour flavor that dissolves in water easily with only a slight residual remainder (swirl the bottom when the glass is almost empty to get almost all of it), no unwanted ingredients, and the powder can be meted out in the dosage YOU need. Price can't be beat. What more could you ask for?

Rated 1 out of 5 by from Doesn't compare to Calm Prior to purchasing this product I had been using Calm. I purchased this product because it was less expensive and the reviews seemed okay. Although the product is effective, it does NOT compare to Calm. It does not dissolve completely and it turns different colors depending upon the liquid it is dissolved in. When I dissolved it in tea, it turned a disgusting almost black color. Without the product the tea is light pink. Unless money is really an object I would not recommend this product.

Rated 5 out of 5 by from Allows me to adjust dose The powdered form allows me to take the correct proportion of magnesium to calcium. Most products contain 2:1 calcium to magnesium, but I've been taught to use 2:1 magnesium to calcium. So I can mix this and my powdered calcium in the right ratio for me. And I've always trusted the NOW brand.

Rated 5 out of 5 by from great source of magnesium Magnesium is necessary for hundreds of essential functions in the human body, yet most people are (often seriously) deficient. Personally, it was the first supplement that resulted in a significant and observable improvement in my fatigue. NOW Food's magnesium citrate powder has none of the fillers used in making tablets. It has a pleasant sour flavor even just mixed with water, although I usually add it to a vitamin/mineral/banana/yogurt smoothie. Very cost efficient in powder form. Note: magnesium is available in various forms -- avoid magnesium oxide (the cheapest and most common) as it is poorly absorbed.

Rated 5 out of 5 by from followed the reviews i read several reviews here on swanson about swansons brand not dissolving so i ordered the now brand and as the other reviews said, it dissolves well and the taste is not bad

Rated 5 out of 5 by from Smooth and Tart! This is my new go-to brand of magnesium. Excellent bioavailable citrate form, and since it's powder, you can spoon out the custom amount you actually need each day. I split up the dose equally with all my meals. This is very smooth and dissolves easily and quickly in water, and its taste is quite tart, just the way a good magnesium citrate should be!

Rated 3 out of 5 by from This product works but tastes so bad I just can't take it. Otherwise I wouldn't mind it.

Rated 5 out of 5 by from NOW Brands Rock I attended a feel better live longer kind of workshop. I learned if you take your supplements iin powder form that the nutrients are quicker to be absorbed by the body. Magnesium is great for memory, assisting with regularity because of the high dosage of calcium (Now Powder too) that I take and a host of other things. It is fresh, mixes well and tastes a little like a sprite soft drink because it is Magnesium Citrate. Give it a go because Swanson has a fairly liberal return policy and their customer service reps have always been consistently efficient, polite and accommodating to me over the many years.
