Don’t Be Fooled By Cheap Synthetic Vitamin C - Not all Vitamin C capsules, pills, tablets or softgels are created equal! Most Vitamin C supplements use synthetic, unnatural formulas and fillers that may increase the risk of poor absorption and ineffective results. At Peak Performance our ingredients are sourced entirely from the USA and derived from Real Raw Whole Food Acerola Cherry for maximum absorption and effectiveness.

Most Supplements Sold Online Are Not 3rd Party Tested! This is a dirty secret that many supplement sellers don't want you to know that their products are Not independently 3rd party tested outside of their own facilities. Why? Because it's an extra out of pocket expense to conduct 3rd party testing and most companies will not sacrifice their profit. But Not Us. Peak Performance is committed to the Highest Standards for your safety.

Don't Be Fooled By Cheap And Even Expensive Imitations! All green superfoods are not the same. Some popular brands use Grass Powder while Peak Performance uses Grass Juice Extract. 20 parts of grass make only one part of grass juice powder - that’s why our grass juice powder is 20 times more concentrated than others. Also, unlike cows our stomachs are not made to digest grass. Our grass juice powder is more easily digestible therefore you absorb the maximum nutrients possible in every serving!
