Health Tools I Wish I Had When I Was Sick

At SelfHacked, it’s our goal to offer our readers all the tools possible to get optimally healthy. When I was struggling with chronic health issues I felt stuck because I didn’t have any tools to help me get better. I had to spend literally thousands of hours trying to read through studies on pubmed to figure out how the body worked and how to fix it.

That’s why I decided to create tools that will help others cut down the guesswork:

  • Lab Test Analyzer – a software tool that will analyze your labs and tell you what the optimal values are for each marker — as well as provide you with actionable tips and personalized health and lifestyle recommendations to help you get there.
  • SelfDecode – a software tool that will help you analyze your genetic data from companies such as 23andme and ancestry. You will learn how your health is being impacted by your genes, and how to use this knowledge to your advantage.
  • SelfHacked Secrets – an ebook where we examine and explain the biggest overlooked environmental factors that cause disease. This ebook is a great place to start your journey if you want to learn the essential steps to optimizing your health.
  • SelfHacked Elimination Diet course – a video course that will help you figure out which diet works best for you
  • Selfhacked Inflammation course – a video course on inflammation and how to bring it down
  • Biohacking insomnia – an ebook on how to get great sleep
  • Lectin Avoidance Cookbook – an e-cookbook for people with food sensitivities
  • BrainGauge – a device that detects subtle brain changes and allows you to test what’s working for you
  • SelfHacked VIP – an area where you can ask me (Joe) questions about health topics

    Hey, are you sure about this name change? Clinical studies seem to indicate L. Gasseri and L. Acidophilus are different strains of lactobacillus bacteria.

    BTW Who cares about weight loss! According to clinical studies, L. Gasseri (and L. Crispatus) are cytotoxic to HPV infected cells, and are directly connected with rapid clearing of visible HPV infections. Not surprisingly, finding a probiotic containing L. Gasseri is difficult in the EU. Not even the best probiotic from New Zealand contains it!

    “L GASSERI” is exactly the same species and genus as L. ACIDOPHILUS. Scientists renamed L. Acidophilus with this “new name” for no decent reason, when people have been calling this precise species of probiotic “Acidophilus”, both scientifically and in common speech, for a hundred years.

    To write an article about this without naming its MORE COMMON name is irresponsible.

      It’s the specific strain that is isolated, which could have different properties. We report what the studies find. It’s not the same species as far as we are concerned. Please share a good source that it is the same species and we will take a look.
