I purchased another brand of L-Methionine originally for my dog. She currently has a problem with bladder stones and I wanted a safe and natural alternative to medications. I decided to purchase this product because it was the raw powder and I was opening the capsules for her anyway. I sprinkle the recommended dosage on her food and she gobbles it right up! I started taking this myself and I will say that I can tell a difference. I feel like I have more energy (extreme fatigue related to health issues is something I have a big problem with), my mood is better and it has been easier for me to make it through my (very!) stressful, and sometimes long, work days. I'm very impressed at how something so simple has made such a difference!You can't beat the price on this. I ordered the 2.2lb package and it was much larger than I was expecting it to be. I was expecting a small package with about a cup or two of powder in it. This is a very generous package, though, with enough powder to last for a while. The package itself is very sturdy and re-seals tightly so there's no chance of it coming open by accident and spilling. I would have had to spend WAY more for the same amount of Methionine in capsules as I received in this 2.2lb package. I prefer the product this way as I can actually see the quality of the powder. The flavor is a tad bitter so I wouldn't advise just taking the powder by itself. It dissolves extremely well in liquids and you don't even know it is there thanks to the flavor of whatever it is mixed with. The powder is gluten free, sugar free, contains no soy, dairy or yeast so you don't need to worry if you're on a special diet.I am extremely pleased with my purchase and will most definitely be ordering this product from BulkSupplements again. The customer service from BulkSupplements is top-notch and my order arrived in good time. Very happy customer, here!
