BulkSupplements.com Magnesium Glycinate Powder - Magnesium Glycinate 400mg, Highly Absorbable - Gluten Free, 2.2g per Serving, 250g (8.8 oz) (Pack of 1)

This tastes terrible and nothing you mix it with improves it any, so I mix it with water and endure. It can improve ones sleep and it's the best form for absorption (so I've read). Most are short on magnesium by all reports I've read. I am not a doctor or medical person. I have studied available information only. I've become used to it taste wise and the powder form is cheaper.

This is a pretty great product. I got my supplements confused and started taking this at one level teaspoon per night. That was great at first later, though it quickly became bad.If your magnesium is low, you can get it up to speed with this product quickly. For example, I took a level teaspoon three or four nights in a row, fantastic benefits, immediate muscle relaxation, and it even made me sleepy. This would be great if you were trying to change your bedtime earlier.Once your magnesium gets filled up, though you will want to lower your dosage. For me, I’m going to take a quarter as much.Some health influencers, recommend titrating to your level of tolerance to magnesium, which I did. Once you hit your tolerance level, you will hit diarrhea.You know you need to back off your dosage at that point.You can’t really dissolve this magnesium glycinate very well. About 70% will dissolve and the rest will remain in little rocks in the bottom of your bottle no matter how hard you shake it.If you put the powder in a blender and blended it on a high setting and put it back into a container, you could get rid of the rocks, but I don’t know.My preferred method is to put it in some water with a little lemon and Stevia not too much water in a Gatorade bottle and up end it drinking it quickly as possible. That way you can get most of the rocks don’t taste great.There’s a lot of confusing information about dosage on here but just go with a quarter or a half teaspoon.

The title of my review should not be construed as a problem with the supplier Bulk Supplements. I consider this product to be a commodity with inherently unavoidable characteristics.See also my in-depth answer to the posted question: "Does this dissolve in water?"The water supplied by our local utility is quite soft. When I vigorously agitate the labeled serving 1/4 tsp of this powder in 12 fl oz of Brita filtered tap water (boiling) I observe that almost all of the powder remains undissolved. After the powder particles settle, a flocculent remains suspended. Next, I try a sip of this mixture and there is a sharp, pungent taste of ammonia.Having some chemistry knowledge, I knew that flocs form as a result of pH conditions. I also knew that aqueous ammonia is alkaline. So I tested a hypothesis that an acid solution might completely dissolve a given quantity of this powder, and also simultaneously release its ammonia into the atmosphere. It turned out that 2 Tbs of boiling white vinegar (labeled as 5% acidity) was just enough to completely dissolve 3/8 tsp of this powder while preventing flocculation and avoiding dissolution of ammonia. This enables 245 mg of elemental magnesium to be absorbed via an empty stomach.But I will instead choose to consume magnesium citrate powder, even though it too is practically insoluble in water. I experimentally discovered that 11/16 tsp can be completely dissolved in just 1 Tbs boiling vinegar. Thus it has approx 5.5 times the solubility of magnesium glycinate (in vinegar). Moreover, it contains 16% elemental magnesium, whereas magnesium glycinate contains only 14% elemental magnesium. So 11/16 tsp of the citrate powder has 383 mg of magnesium. Considering that the gycinate powder is denser than the citrate powder, in order for the glycinate powder to match that I would need just 0.59 tsp of it. But... The magnesium glycinate must first be dissolved in 4.7 Tbs boiling vinegar. No, thank-you.Perhaps this product should be regarded first and foremost as a source of glycine rather than primarily as a source of magnesium. However, beef gelatin is also a source of glycine, and its ammonia (if present; probably not) is low enough so as to be tasteless. Moreover, it's easily dissolved in boiling water, obviating the need for vinegar, which is corrosive to tooth enamel. But its dry granules have a glycine content of only 27%, compared to this product's glycinATE content of 86%. Suppose I consume 1 Tbs of beef gelatin granules (after dissolving them in boiling water). I would be getting 2.6 g glycine. In order to match that in glycinATE, I need only consume 0.64 tsp of this product, but the caviat is that it must first be dissolved in a little over 5 Tbs boiling vinegar. Again, no, thank-you.In summary, the alternatives to this product are not only inexpensive, they are also more effective (superior solubility) and are FAR SAFER (This item is contaminated with ammonia and at least one insoluble powder). So if magnesium is the reason for your consideration of this product, then magnesium citrate is the better choice. Or if glycinate is what you're after, then choose gelatin granules instead of this item.
