Dr. Alex's Wellness Programs

Dr. Rinehart's 48-Hour Gut 
Reset Program

Jumpstart your digestive health with the 48-Hour Gut Reset Program. This program utilizes an elemental diet, composed of easily digestible meal replacement shakes, to provide your body with all essential nutrients in their simplest forms while allowing your gut to rest and recover. The program supports bloating and inflammation, gut motility, a healthy balance of gut bacteria, occasional digestive discomfort, and immune flare-ups.

2-Gram Fish Oil Challenge Box (Nordic Naturals)

The 2-Gram Fish Oil Challenge Box provides a powerful boost to your overall health. With a daily dose of 2000 m g of EPA and DHA, it significantly supports heart, brain, and immune functions. The included before and after OmegaQuant test kits allow you to track improvements in your omega-3 levels and optimize your intake for reduced inflammation and better cellular health. Your Omega-3 Index results are as predictive to long-term health as smoking, diabetes, and more. Know your number, and re-test to show you that your fish oil is making a difference.

Microbiome Labs Total Gut Restoration Protocol

The Microbiome Labs Total Gut Restoration Protocol is a comprehensive three-month plan designed to rejuvenate and optimize your digestive health. This program utilizes a strategic three-step approach to support all aspects of gut health. It begins with Recondition, using Megasporebiotic to balance gut bacteria. The second phase, Reinforce, adds MegaPre to promote the growth of beneficial bacteria. The final phase, Rebuild, adds Megamucosa to support the gut lining.

The Nitric Oxide Challenge

The Nitric Oxide Program utilizes nitric oxide testing strips and a nitric-oxide supportive supplement. See for yourself exactly when you need nitric oxide support, and re-test to confirm the supplement is working. As we age past 40, our ability to produce nitric oxide drops 50% and by age 60+, it drops 80%! Yet, when you take daily supplemental nitrates, they utilize a separate pathway – bypassing age-related nitric oxide decline. Support sexual health, brain function, muscle performance and recovery, and other supportive benefits for immunity, sleep, and more.

What Our Clients Are Saying

In my years as a medical educator both in academia and in the industry, I meet a lot of “wanna-bes”. These are doctors or professionals who appear from the outside to be experts. They claim to be thorough. They exhaust their efforts externally on how they appear to be rather than how they truly are. Dr. Alex Rinehart is NOT a wanna-be. He is the consummate professional when it comes to the functional approach to human nutrition and disease. He pairs his expertise with a very human side, making him both a master health coach as well as an authority on the science of healthy living.

Dr. Corey Schuler 

Director of Medical Science for Gaia Herbs

Dr. Rinehart’s products have been my “go to” for a few years now. The megasporebiotic has gotten me back on track whenever I have messed up my system with poor food choices!

I follow the protocol suggested, and then stay on the Microbiome for two or three months (or longer) to give my gut time to heal. Never fails! I have confidence in the research behind these products. In addition, Customer Service is perfect – the products arrive quickly and well-packed. Amanda is the best at helping me understand what each product is for so I can decide what to order.

Connie T.

I have been purchasing products from Dr. Rinehart for a few years and find his company and staff to be helpful, knowledgeable and professional. The website is so “friendly”…I appreciate clarity, details and good photos when selecting a supplement. Each product includes a full description, the ingredients, supplemental facts, suggested use, and warnings. I use their auto-ship feature to ensure my product arrives at specific intervals. I like not having to think about refills, they take care of it for me. I highly recommend Dr. Rinehart’s company as I have always had a positive, stress-free experience.

Barb E.

You have no idea how excited I am to find your site. I recognize so many brands like Orthomolecular that are reputable and high quality.
