What Endurance Athletes Are Saying about Runners Essentials

The biggest change I’ve noticed is in recovery. My legs feel fresh every day, not tired or heavy. I’ve also been battling through a hamstring injury for a few months and since starting Runners Essentials I’ve noticed significant progress. Overall I feel that I have more energy and strength during my workouts.”

DM - Active Duty USMC / Marine Corps Marathon x 8 / Ultra Marathoner

I was truly amazed at how different I began to feel after a week of consistently taking them. During training runs I noticed I was less sluggish and had more stamina than in previous months. Actually knocked off a minute on my mile pace... after about 3 weeks I noticed that mile pace was consistent or even led to a negative split for the whole run. That hasn’t happened for me in years. I am so pumped!!!!!"

MC - Half Marathoner

These vitamins are amazing. This 65-year-old runner ran her second fastest marathon at Boston, 5 years after a PR at WB marathon and first BQ. So happy with this addition to my daily routine. They definitely help with recovery and training”

PK - World Marathon Majors Six Star Finisher, Two Runners Travel and Local Running Legend

My sleep quality has noticeably improved; I recover quicker from every kind of workout; I run faster with less stress; my overall well-being has improved and that's the best thing that could have happened to me."

DE - Half Marathoner, Triathlete

Highly recommend #runnersdailyvitamin I didn’t feel a difference for a bit, but now they’ll be my forever vitamin! I DO feel a difference and I believe you will too! ...They have been wonderful during this marathon training phase and I feel better knowing fellow runners and nutritionists formulated a perfect combination to fuel the runner’s needs."

ALP - Full Marathoner

Runners Essentials has given me more focus throughout the day and I am also recovering much better between runs and speed workouts. It is almost like I am motivated and ready to run each day more consistently. There is no miracle, but Runners Essentials is giving me the extra energy I need during half and full marathon cycles. Great product!"

TC - Elite Runner / AG Triathlete

I have had back pain for months. After starting the RE supplements, I started feeling less pain without doing anything different. My husband thinks I'm crazy but I think the supplements actually are helping my back. My problem is an inflamed SI joint from excessive running. I've been stretching more but I credit my feeling better to the supplements!! Thank you so much!”

GB - Triathlete

I was honestly not sure how this would effect me because I have Crohn’s and it’s been bad enough where I had to stop running completely, but I can honestly say ever since I started taking these vitamins I started feeling alive again and I’m now back out running and training doing what I love. My wife and now my 13 year old son now take this product and it’s been a game changer. Would definitely recommend to any endurance athlete."

DG - Full Marathoner

As an avid runner, surfer, and old man, it’s imperative that my body gets what it needs on a daily basis....Usually, my first miles after a hard workout or long run are labor intensive because my hamstrings, quads, and body ache with soreness or tightness from the previous day’s work. I have noticed that I recover significantly faster and have experienced a noticeable decrease in soreness. I went into this thinking I’d buy one bottle and that would be it. I thought all vitamins were basically the same, but clearly they are not. I’m a believer in Runners Essentials Daily Vitamin now!"
