Gene Types Explained

Some search terms matched

Your genetic results might list “wild type,” “heterozygous,” or “homozygous,” but what does that mean? Wild type means both copies of your gene are normal, heterozygous means one is normal and one has a change, and homozygous means both copies have the same change. With genes like MTHFR, these variations can affect how efficiently your body processes nutrients like folate—sometimes cutting function by 40–70%—which is why targeted nutrition and testing matter.

Be Wary Of Glutathione Product Claims!

Some search terms matched

Many skincare and supplement companies throw around the word “glutathione,” but most of their products don’t actually deliver meaningful amounts—or the right form. For example, a popular serum claims anywhere from 50,000 ppm to just 500 ppm glutathione, which would equal almost nothing per bottle. On top of that, most products use oxidized glutathione, which doesn’t work in the body. That’s what makes VARS Glutathione different—it stays in its reduced, functional form all the way until your cells use it, giving you a real therapeutic dose that actually works.

Ge Gene SNPs Cause Vitamin Deficiencies?

Yes—your genetics can directly cause vitamin deficiencies. Certain SNPs lower your body’s ability to process or make key nutrients, like MTHFR reducing folate use, PEMT lowering phosphatidylcholine production for gut and liver health, and SOD decreasing antioxidant defenses against free radicals. These deficiencies drive inflammation, fatigue, and chronic illness, but with the right genetic and intracellular testing, you can target them and supplement with the exact forms your body needs Info: http://www.DanPurserMD.com Supplements: https://www.PhysicianDesigned.com Books: https://www.amazon.com/-/e/B00BIKSGVQ Facebook: https://www.facebook.com/danpursermd Facebook: https://www.facebook.com/PhysicianDesigned Twitter: https://twitter.com/realdanpursermd YouTube: https://www.youtube.com/danpursermd Instagram: https://www.instagram.com/danpurser.md Pinterest: https://www.pinterest.com/danpursermd
