"This elegantly written and totally absorbing memoir describes renowned physician-scientist Dr. Nathanson`s passionate and exciting search for a hidden lymph node in breast cancer and melanoma patients. We share his scientific/medical discoveries which have eased the trauma and complications of many patients. We share and absorb his excitement of scientific discovery. Read it and you will be transported to the wondrous world of medical science and patient care at its best." - Michael Chopp PhD, Zolton J. Kovacs Chair in Neuroscience Research, Henry Ford Health System; Distinguished Professor, Physics, Oakland University, Rochester, MI

"This delightful memoir is a wonderful window into the exciting world of biomedical research. It relates the story of Dr Nathanson’s persistent fascination with lymph nodes and the lymphatic system which enabled him and others to identify the sentinel lymph node, allowing the eventual use of this new knowledge to optimize the care of breast cancer and melanoma patients world-wide." - Margot LaPointe PhD, Vice President for Research, Henry Ford Health System, Detroit, Michigan, USA

"Doctor Nathanson’s memoir is a vivid, exciting and invaluable reflection on his unique insights into the scientific discovery of the sentinel lymph node, providing the reader with a clear understanding of the fascinating world of scientific discovery that has advanced the management of breast cancer and melanoma."  - Stanley P. L. Leong, MD, FACS, Chief of Cutaneous Oncology Center for Melanoma Research and Treatment California Pacific Medical Center Research Institute

"A succinct description of a lifelong devotion to understand how cancer spreads to lymph nodes. More important to the general reader might well be the excitement and fascination of the clinical and scientific discovery of hidden knowledge." - Rupen Shah, MD, FACS, FSSO, Surgical Oncologist, Henry Ford Cancer Institute, Detroit, Michigan

"Motivated by his patients and driven to find a better way, Dr. Nathanson shares his inspiring journey of discovery to spare cancer patients the awful fate of lymphedema, a life-altering complication of lymph node surgery for cancer. Using heartwarming stories from his own life as well as raw conversations with patients who he treated along the way, this memoir shows how basic science can improve the lives of millions." - Timothy Padera PhD, Associate Professor, Department of Radiation Oncology, Massachusetts General Hospital, Harvard Medical School, Boston, Massachusetts, USA

"A superbly written, uninhibited, wonderfully and delicately interwoven set of experiences that culminate in a gripping story of how a curious mind is transformed by a fascination with the human lymphatic system. The memoir is an example of how tenacious and repetitive enchantment with the process of discovery contributed to sentinel events that have forever changed how cancer care is delivered all over the world." - David Kwon MD, FACS, FSSO, Physician in Charge, Brigitte Harris Cancer Pavilion; Director, Surgical Oncology, Henry Ford Cancer Institute, Detroit, Michigan USA

"The Concealed Revealed is a memoir of S. David Nathanson’s contributions to the development of the sentinel node biopsy in cancer management, a procedure that has completely changed the way we treat breast cancer, melanoma, and other forms of cancer. Nathanson’s excitement and determination is evident throughout his time investigating better methods for cancer patients in providing them with a better quality of life than previous treatments, which left patients with life-altering swelling and loss of limb functionality. From his early years in South Africa to his move to the United States, we follow Nathanson on his tireless journey in understanding the complexities of cancer treatment. His curiosity and innovative spirit are inspiring and will encourage readers to follow their own passions."

2 months supply, tasty berry bubblegum flavor, no morning cramps.
I've been taking Magnesium supplements for a long time, usually in capsule form. Starting from about age 45 I kept getting these awful morning calf cramps. Especially stretching, or on cold morning. The sudden agony was unexpected and concerning. Magnesium is the answer and this water-soluble magnesium from Thorne is no exception. For this particular problem, calf cramps. The results are noticable within a couple of days. If I stop taking magnesium for 3-5 days the cramps come back. Thorne powder has a berry flavor that is very similar to bubble gum. It dissolves easily without leaving any lumps. Is great to help you take your other supplements. I've been taking this for about 3 weeks with no cramps. Price is a little higher than capsules typically are. This works for me and the tub should last two-months if you follow the directions.

Easy Way to Add Magnesium Support
Magnesium is one of those supplements many people find helpful as part of their wellness routine. The powder format makes it easy to adjust serving sizes and mix into drinks. One thing I liked was the citrus berry flavor, which made it more pleasant than many unflavored supplements. Overall, a convenient magnesium option from a well-known brand

Great Taste and Mixes in Water Well
I’ve been using this magnesium citrate powder for a little while now, and overall it’s been a positive experience. One of the standout aspects is how well it mixes. It dissolves easily in water with minimal residue, which makes it much more convenient compared to some other powdered supplements I’ve tried. The citrus berry flavor is also quite good: light, slightly sweet, and easy to drink without being overpowering. The powder format makes it simple to adjust how you take it (more or less water, etc.), and I didn’t notice any strong aftertaste. From a general usability standpoint, this checks the boxes I look for in a supplement: good taste, easy mixing, and consistent quality. Thorne also has a strong reputation, and this product feels in line with that in terms of formulation and overall experience. As with any supplement, individual experiences can vary, but from a taste, mixability, and convenience perspective, this has worked well for me. Overall, this is a solid option if you’re looking for a magnesium citrate powder that’s easy to take on a regular basis.

Great Magnesium Blend That Actually Works
Size: 100 Count (Pack of 1), Size: 100 Count (Pack of 1)
I’ve been taking Life Extension Magnesium Caps (500 mg) for a few weeks now, and I can really feel the difference. It’s a blend of magnesium oxide, citrate, and succinate, and I’ve noticed improved sleep quality and fewer muscle cramps at night. The capsules are easy to swallow and don’t upset my stomach, which has been an issue with other magnesium supplements I’ve tried. Plus, I like that they’re vegetarian-friendly and come in a 100-count bottle, which lasts a good while. What I appreciate most is how balanced this formula feels. I take it mainly for sleep, muscle support, and overall well-being, and I genuinely notice I feel more relaxed, especially in the evenings. For the price and quality, it’s a great value. I’ll definitely keep this one in my daily routine.

This Magnesium Is Worth It!
Size: 100 Count (Pack of 1)
Life Extension is a quality company, and this Magnesium is very good. I have been taking it for maybe a year, and it helps me steer clear of debilitating nightly leg cramps, and also helps my digestion from getting sluggish. I don't really see any reason to change brands, because I trust Life Extension to deliver a high-quality product, so I'm just gonna stick with it. Recommended!
