Brain Booster!
I have finished my first bottle and I could really tell a difference. I have found nothing but positive results by taking brain boost in the morning, Mag SRT at noon, and Mag Soothe in the evenings. These are the best magnesium supplements on the market!

Love it!
Truthfully this stuff is amazing! I have never realized just how groggy I was until I started taking this stuff. Majority of my job is multitasking and with this I can always remember everything I have to do, I feel so much more awake and more aware of everything. Truly is life changing. :)

MagSRT® utilizes Albion Lab's premier patented Dimagnesium Malate and slowly releases it over an extended period of time. MagPure™ Brain Boost utilizes Magtein® Magnesium L-threonate, and does not have the Sustained Release Technology (SRT) that MagSRT® uses. They are both great forms of magnesium, and we recommend using MagPure™ Brain Boost in conjunction with MagSRT® to give your body ample supply of magnesium while fueling your brain with this targeted formula.
Magnesium is a critical mineral for your overall health including many of your brain's functions such as learning abilities, working memory, and short-term and long-term memory.*
The special form of Magnesium used in our Jigsaw Brain Boost -- Magnesium L-Threonate -- has been clinically tested and shown to permeate the blood-brain barrier, which enhances the receptors involved in supporting healthy short-term & long-term memory, and improves learning abilities.*
Each serving of Jigsaw Brain Boost contains 144mg of elemental Magnesium that is quickly released into the bloodstream to fuel your brain.*
The Recommended Dietary Intake (RDI) for Magnesium is 420mg per day and is the minimum amount required to avoid a deficiency — not necessarily the maximum amount required for optimal health.*
Jigsaw Brain Boost™ provides 144mg of magnesium per serving so we recommend taking this in addition to our MagSRT® to easily and conveniently exceed the RDI for magnesium without getting the terrible side effect of diarrhea caused by ordinary magnesium supplements.*
Many of our customers see results in about 2 weeks while others need a little longer depending on their body and needs.*
We love our products and we believe you will too. However, if you are not completely satisfied, please contact us within 90 days and we will gladly refund 100% of your purchase.
No need to send the products back, please consider sharing with a friend or family member.

Ben Greenfield

Magnesium is a KEY part of my evening routine, and I've found nothing better than MagSRT. In addition, I'm now using a giant scoop of Adrenal Cocktail in my morning mason glass jar of water, then adding in a few capsules of Pureway-C anytime I need extra immune system support. I stand behind all of Jigsaw's products.

I’ve been using MagSRT®, MagSRT® B-Free and MagSoothe™ with the kiddos in my clinic and we love them! They are such a great and gentle way to deliver magnesium. My personal favorite and the one I take every day is the MagPure® Brain Boost. Works like a charm!” Thank you Jigsaw Health for making such incredible products!

Dr. Decker Weiss
Naturopathic Cardiologist, Founder of Scottsdale Heart Institute, Peace Possible
For my practice, magnesium is critical to protect my patients. MagSRT sets itself apart in many ways including the only one to meet the standards a cardiologist such as myself demands. I switched over 3 years ago based on the Scottsdale Magnesium Study results, and have never gone back to any other magnesium product.

I always keep my family stocked up on Jigsaw MagSRT and CoQ10 and recommend it for all my patients. I love this company! It is rare for a supplement company to do research on effectiveness of a vitamin-they do and have! I appreciate the deep emphasis on quality.
