Nutrients

Nitrogen 4% Nitrogen is the mineral element used in the greatest quantity by plants. Nitrogen is a component of many of the biochemical constituents of plants, including chlorophyll, amino acids, proteins, and enzymes. 

Phosphorus 6% The proper phosphorus level in your grass is essential for root and early plant development. Its primary role is in the storage and transfer of energy. Without sufficient P, normal growth and development cannot occur. Phosphorus effects on plants are usually more subtle and, while not as readily visible, are still very important.

Potassium 8% Potassium is involved in carbohydrate formation, photosynthesis, enzyme activation, and the formation of proteins. Potassium plays a role in photosynthesis, and carbohydrate production is reduced when K is deficient.  A plant deficient in Potassium can be more susceptible to stress from drought and temperature. 

Humic Acid helps promote the release of locked-up nutrients in the soil to increase fertilizer transfer. 

Seaweed as added organic matter to the soil.

CHOKING HAZARD
Flavor Name: Bone (S), Size: 6 Count (Pack of 1)
CHOKING HAZARD: I purchased these bones for my small Yorki.. He ate the first two without incident; however, on the third bone he unfortunately choked. As the bones wear down, they become extremely stringy, and those strands do not appear to be digestible. I had to rush my dog to the emergency room, which cost $700. Three days later, he became even sicker because he was unable to pass the remaining portion of the bone still in his stomach. I then had to take him to his regular veterinarian, where he was admitted overnight and diagnosed with pancreatitis and a severely irritated gastrointestinal tract. This entire ordeal cost me over $1,500 in addition to the initial $700 emergency visit. I am grateful that my dog is now alive and well, but these bones pose a serious choking hazard and do not digest properly. I strongly caution other pet owners, especially those with small dogs.

High-Quality Magnesium That’s Gentle and Effective
Size: 90 Count (Pack of 1)
This magnesium glycinate is easy to take and very gentle on the stomach compared to other forms. It absorbs well and is a great option for supporting relaxation, muscle comfort, and overall well-being. It’s especially helpful for easing tension and can support better sleep when taken regularly. Magnesium glycinate is known for its high absorption and calming effects without causing digestive upset. The capsules are a bit larger, but still manageable and worth it for the quality. Overall, a reliable and effective magnesium supplement.

Gentle Gentle Magnesium That Helped My Night Routine
Size: 90 Count (Pack of 1)
I bought the Thorne Magnesium Glycinate Capsules (90 servings) for $25 because I wanted a magnesium supplement that could support relaxation and better sleep as part of my nightly routine. I’ve been taking it for about a month and noticed I feel more relaxed in the evenings and wind down easier before bed. I also tend to get tension and poor sleep when I’m run down, so having magnesium in my routine has been helpful for overall balance. The capsules are easy to swallow and very gentle on the stomach, which I appreciate because some magnesium supplements can cause digestive discomfort. Magnesium glycinate is also known for being one of the more absorbable and well-tolerated forms of magnesium. I actually ran out for about a week while waiting for my reorder, and that’s when I realized how much I liked having it in my routine. Once I started taking it again, it quickly became part of my evening habit. The only downside is the price is higher than some other magnesium brands, but Thorne has a strong reputation for quality and third-party testing, which is why I chose it. Overall, this feels like a high-quality magnesium supplement and a good option if you’re looking for a gentle, easy-to-tolerate form of magnesium.

Thorne Magnesium is a total game changer! The quality is exceptional, and it has finally helped me get the restful sleep I've been missing. I’ve struggled with insomnia and tried numerous other brands to no avail, but Thorne is truly superior. It is absolutely worth the investment for results that actually work.
