    Paws the vote is in and it got three out of three
    Three puppies voted paws up for taste and a little bit of longevity. Now as for value for money. I know how much better than rawhide treats. But I’d like to see the price come down and more chewy’s inside the bag

    So so small! Not worth $
    The images in Amazon are nothing like what the product is. The pretzels and rings are minuscule. My two pit/lab mixes will eat one in about 30 seconds. So disappointment. Not worth the $ for what you’re getting. I tried to return items which are individually wrapped but they do not allow returns on these products. I have not opened any of them and still not able to return. If you have a dog under 15lbs these may work! If you have a large breed don’t bother. I’m so disappointed. Pictures above is the product next to a small milk bone biscuit (for reference).

    A Premium Magnesium Powder From A Brand I Actually Trust
    Thorne has a strong reputation in the supplement world, and this Magnesium Citrate powder is a good example of why. Magnesium is one of those basic minerals that does more than people realize. It supports normal muscle and nerve function, helps with energy production, contributes to bone health, and plays a role in cardiovascular function. The NIH notes that magnesium is involved in hundreds of enzyme systems in the body, including processes tied to muscle and nerve function, blood glucose control, blood pressure regulation, and bone development. (Office of Dietary Supplements) Magnesium citrate in particular is a form many people use because it is generally well absorbed and can also help with occasional constipation. That is both a benefit and something to respect. If you take too much, it can move from “helpful” to “where is the nearest bathroom” fairly quickly. I would start modestly and see how your body responds. The citrus berry flavor is pleasant enough for a mineral powder. It is not candy, and it does not need to be. It mixes reasonably well and is easy to work into a nightly routine or use when you feel like your muscles are tight, your diet has been less than ideal, or you simply want magnesium without swallowing another capsule. The biggest selling point for me is the brand. Thorne is not some mystery-label supplement company with a pretty bottle and a warehouse address nobody wants to talk about. Thorne says its facility is NSF certified, it manufactures more than 40 NSF Certified for Sport products, and it is used by professional and national sports organizations. (Thorne) Their Magnesium Citrate product page also states that the product is third-party tested and certified to verify what is in the package. (Thorne) That matters with supplements. You are not just buying magnesium. You are buying confidence that the dosage, purity, and manufacturing standards are being taken seriously. Thorne usually costs more than bargain brands, but with supplements, cheap is not always the victory it looks like on the front end. Overall, this is a high-quality magnesium option from a brand with real credibility. I like it for muscle support, general wellness, bone and heart-health support, and occasional regularity. Just treat it like a supplement, not a snack, especially if you are sensitive to magnesium or already taking other products that contain it.
