Review: Did not say - Did not work ## Features - Improve Performance: PeakO2 is a powerful adaptogenic blend of six organic Ayurvedic mushroom strains (Cordyceps, Reishi, King Trumpet, Shiitake, Lion's Mane, and Turkey Tail) that may enhance athletic performance and boost overall health. It’s increasingly popular among athletes and fitness enthusiasts for its potential to increase endurance, improve oxygen utilization, and enhance recovery. PeakO2 may also boost energy levels, improve mental clarity and focus, and enhance the immune system - More Energy: A main benefit of PeakO2 is it may help increase ATP production, the body’s primary energy source. By helping to boost ATP levels, PeakO2 may help improve overall energy levels, allowing you to work out longer and harder without feeling fatigued. Additionally, PeakO2 may improve VO2 max, the maximum amount of oxygen your body can use during physical activity. By potentially improving VO2 max, PeakO2 may help you perform better during high-intensity workouts and competitions - Exercise Benefits: PeakO2 may help increase oxygen uptake by providing your body with the ability to use oxygen more efficiently during exercise, as well as it may help reduce lactate buildup, one of the leading causes of fatigue during physical activity. By reducing lactate buildup, PeakO2 could help delay the onset of fatigue, allowing you to push through barriers that would have normally stopped you in your tracks - Post-Workout Recovery: In addition to reducing lactate buildup, PeakO2 may help improve recovery time. By improving recovery times, PeakO2 may help you recover more quickly between sets or after a workout, allowing you to maintain your performance for extended periods. PeakO2 may also help reduce oxidative stress, which can cause damage to your muscles and brain, leading to mental and physical fatigue - Quality Third Party Tested, Full Disclosure: Our PeakO2 supplement is USA-made, kosher, and adheres to FDA 21 CFR Part 111 c-GMP regulations. It undergoes third-party testing for purity and quality, with fully transparent labels and no proprietary blends, aligning with our commitment to excellence. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CJMRW8SD | | Best Sellers Rank | #259,468 in Health & Household ( See Top 100 in Health & Household ) #1,420 in Mushrooms Herbal Supplements | | Customer Reviews | 4.1 4.1 out of 5 stars (6) | | Date First Available | January 24, 2024 | | Item model number | 21870 | | Manufacturer | NutraBio | | Package Dimensions | 3.62 x 3.62 x 3.58 inches; 4.23 ounces | ## Product Details - **Age Range (Description):** Adult - **Brand:** NutraBio - **Diet Type:** Gluten Free, Halal, Kosher, Vegetarian - **Flavor:** Unflavored - **Item Form:** Powder - **Item Weight:** 120 Grams - **Primary Supplement Type:** Mushroom - **Special Ingredients:** Cordyceps, Reishi, King Trumpet, Shiitake, Lion's Mane, Turkey Tail mushrooms - **Unit Count:** 4.2 Ounce ## Images ![- NutraBio Labs Peak O2, Unflavored, 4.2 oz (120 g), Nutritional Supplement - Image 1](https://m.media-amazon.com/images/I/61ciYenypTL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Been taking this for years *by L***Y on January 14, 2025* Very high quality and it absolutely works!! ### ⭐ Did not say *by G***S on May 6, 2025* Did not work ## Frequently Bought Together - NutraBio Peak O2, Unflavored, 4.2 oz (120 g), Labs - NutraBio CarboMax Maltodextrin Powder - Carbohydrate Powder for Sustained Energy - Calorie Rich for Muscle and Weight Gain - Unflavored - 5 Pounds, 75 Servings - NutraBio Pure L-Glutamine Powder - L-Glutamine Supplement- Amino Acid - Pure Grade: Absolutely no Additives, Fillers or Excipients! - Muscle Recovery Supplement - (500 Grams) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/607953631-nutrabio-labs-peak-o2-unflavored-4-2-oz-120-g](https://www.desertcart.pt/products/607953631-nutrabio-labs-peak-o2-unflavored-4-2-oz-120-g) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-06-06*
