Research-Supported Benefits:

Supports Cognitive Function. Magnesium threonate is essential for maintaining between-cell signaling and promoting the growth, maturation and survival of neurons and their networks. Magnesium threonate crosses the blood-brain barrier and boosts the production of brain-derived neurotrophic factor (BDNF), a protein that promotes the survival and growth of neurons. Clinical research shows that magnesium L-threonate in the form of Magtein® can significantly improve executive function, working memory, attention and episodic memory. This cognitive improvement was equivalent to a nine-year reduction in their overall brain age.1,2

Supports Healthy Mood. Magnesium threonate supports a healthy mood because it plays a role in neuronal signaling and BDNF production. Magnesium threonate is also involved with the function of some neurotransmitters, including GABA, serotonin and dopamine. Research shows that adults aged 50 to 70 who took Magtein® for 12 weeks had significant reductions in stress-related anxious symptoms and feelings of fear compared to the placebo group.3

Supports Sleep. Magnesium is known to support healthy sleep patterns, including increasing total sleep time, reducing sleep latency (the time it takes to fall asleep) and improving sleep efficiency.4

Perfection!
Format: Paperback
I have read this before digitally, and this is just as beautiful in the physical copy. It arrived in excellent condition. This is my favorite Lovecraft story, and it completely lives up to all expectations. Gorgeous art, moody, faithful to the story, and very detailed.

What adaptations ought to be
Format: Paperback
An amazing adaptation of Lovecraft's classic story to manga that changes only what needs to be changed to make the story work in the new format. The plot is the same, the art is incredibly detailed -- almost too much so -- and the changes in the plot are done only to deal with the vast amount of pure narration in the original. And they're intelligently done. This is how to do it. If you liked the original Shadow over Innsmouth, I think it's safe to say you'll love this.

High quality manga adaptation
Format: Paperback, Format: Paperback
I bought this, along with several of the other paperbacks in this manga series. They are all the same height and width and fit nicely together on my shelf, which is nice. All of the art is incredible. Some really detailed and haunting images. Most pages are black and white, but there are a few awesome images in color throughout the book. The quality of the book itself is great, and it's made with solid paper (not too thin). As someone new to Lovecraft, I really appreciate these versions of his stories which I'm told are true to the original writing.

Best in the series so far
Format: Paperback
I have loved all of the graphic novels of the H.P. Lovecraft stories but this one is by far my favorite. The detail on character expressions nicely compliment the story and is a wonderful interpretation of the source material.

Perfect Adaptation of Lovecraft's Story
Format: Kindle
Gou Tanabe has been making probably the best manga/comic adaptations of Lovecraft's works recently, and this depiction of "The Shadow Over Innsmouth" is by far the best. Tanabe really captures visually what Lovecraft was conveying via the text of the original story. Innsmouth is decrepit and rotting, the locals are sinister, and the deep ones are hideous. And, as always, Tanabe's art is of the highest quality. I can't recommend this enough, and I eagerly await whatever adaptation he does next.
