My last post included a link to a video by Dr. Rhonda Patrick on vitamin D and the importance of that vitamin. She made a reference to testing relatively frequently to make sure you are in the optimal range (40 to 60 nanograms).
I test every six months with InsideTracker. They have quite a suite of biomarkers that they test for, including vitamin D and many others that are performance related (testosterone, cortisol, hemoglobin, among others). I’m used the information I’ve gained to alter my diet and make adjustments to my other routines.
Send me a note if you’re interested in finding out more. I may have a discount code that I can give you if they aren’t running any specials (no benefits to me; I’ve asked for one in the past and they’ve obliged for clients/referrals).
