    An excellent product. Exactly what you would need if you are looking for magnesium glycinate. It is obvious that a certain level of care and passion goes into this company and their products. A! customer service and products so there really is no reason to get this elsewhere. On top of that you get to support a small player on the game that cares about you. I also noticed others did not like the taste, I places the scoops directly into my mouth and found no weird taste. But I imagine that's just what this stuff tastes like lol.

    Exactly what I need… but disgusting.

    This is a great product, and it is clear that the folks at Lark care. Being able to be certain about the purity is amazing. The only thing that stops me from giving this 5 stars is that it’s just wretched tasting. I wanted to mix into a glass of warm milk in the early evening but it ruins the milk. Frankly, I haven’t found a great way to take this yet, even though it’s definitely what I need for my health. Would love an encapsulated version, or for Lark to sell gelatin capsules so I can choose my dosage.

    Tastes awful but that's expected. Would love a capsule version
