| Dr. Emil Nutrition | 9.79 | ✅ | ✅ | ✅ |
Strongest pill form dose - Our 3150 mg serving is the highest available in pill form and is more than 2X that of other leading brands; Get the same dosage (or higher) than a powder without the hassle.
Potent N.O. booster - our optimal blend of AAKG & Arginine HCI is designed to enhance N.O. levels, aiding blood flow to the organs & muscles leading to greater energy & vascularity.
3x more than competitors - our formula contains 2-3X more Arginine per dose than other leading arginine supplements in pill form, which generally only contain 1000-1500 mgs - a dosage range studies have shown to be significantly less effective in promoting nitric oxide enhancement.
Doctor-driven, science-backed - bringing Dr. Emil’s unique knowledge as both a medical doctor & recognized authority in the supplementation field (he’s also a former pro athlete!), our blends are painstakingly formulated to provide superior results and are always backed by science - free of gimmicks, fads & false promises.
Only the right stuff - all Dr. Emil products are made from all-natural vitamins, minerals & herbal extracts, without the use of harmful additives; NON-GMO and free of hormones & gluten. All products are manufactured in the USA in a GMP certified laboratory.
