I read the Life Extension Practical Scientific Approach in the first part of 1983. I mostly memorized it and also read many of the scientific references made in the book. (Like a new language at first) I started experimenting right away (following safety rules of course) I kept up my research and still do. There were no formulas available at first. Twinlab copied the formula in the book to the letter including 3g of niacin per day. Safe but big flushes. (The newer formulas have a lot less niacin) Expensive too. $47 every 2 weeks in 1984. That’s $120 every 2 weeks in today’s money. Wow. Life Priority was formed and I started using their products. (That was quite a while ago) Today Life Priority provides my wife and I the majority of the supplements we take. They also have very strict manufacturing protocols which make sure we get what’s on the label and it that doesn’t have any questionable ingredients. Their supplements are backed up by science and anyone that says there’s no research on these ingredients is woefully ignorant. (Sorry, I get a little worked over willful ignorance) The research is available to anyone with a computer or smartphone. I did make a decision to make Durk and Sandy my trusted scientists and stopped a lot of my research that was already covered by them. Having geniuses research and conclude for me was an easy decision. Being the smart people they are at Life Priority they have faithfully provided supplements that reflect the cutting edge of nutritional science and beyond. Like Durk Pearson said, “If there is only one thing I could take it would be the formula in Life Shield.” That is the foundation of my life extension program. Thank you Greg and Michelle Tom Selden

I have been using V Guard 2 and the original version of V Guard for a couple of years. I work for a Chiropractor and we sell Life Priority products. I started using the V Guard when Covid first started to build my immune system since I am a heart patient as well. I love the ease of use with having all of the supplements in one capsule instead of taking multiple products. I take usually two a day, one in the morning and one at night. I increase the dose to 4 when I am feeling congested. It is an excellent product that I would suggest for anyone.
Fantastic immune system supplement, take it every day!
I have been V-guard for 1 month. I have been exposed to alot of "stuff". I am excited to have this supplement to use for my immune system. I love the research and scientists who created this product! To your health!
