Yes, Please! This isn’t just a protein powder—it’s a total mind and body upgrade! Four Sigmatic has taken plant-based protein to the next level by adding functional mushrooms like Lion’s Mane, Chaga, and Cordyceps.

If you want more than just muscle recovery—if you want a brain boost with your protein—this is the one. Worth every cent! 11/10 – Revolutionary! Review: BEST PROTEIN DRINK - I’ve been using the Four Sigmatic Organic Plant-Based Protein Powder for a few weeks now, and I’m really impressed! The peanut butter flavor is delicious, and it mixes smoothly into smoothies or shakes. What really sets this protein apart is the addition of medicinal mushrooms like Lion’s Mane, Chaga, and Cordyceps. I’ve noticed a boost in my mental clarity and energy levels since incorporating it into my daily routine. ## Features - PLANT PROTEIN, PERFECTED — Our notably nutritionally-dense superfood packed protein powder is crafted with pure plant protein, functional mushrooms, pretty-much-magical adaptogens, and no fillers whatsoever. You’ll love what it does for your everyday. - CHEF-WORTHY, ORGANICALLY SWEETENED — We didn’t skimp on any ingredients. We’ve rejected the artificial and gone sucralose-free, refined sugar-free, and even stevia-free. Our protein powder is instead sweetened with the natural flavors of organic coconut milk powder, organic coconut palm sugar, pink Himalayan salt, and organic monk fruit. - THE PERFECT PAIRING FOR A PB + BANANA SMOOTHIE — Most people seem to agree that jelly is peanut butter’s best pair. But we’re over here on team PB + banana. Rather than artificial flavors and extracts, we use real peanuts grown in the USA to give our protein powder a real peanut butter taste. - LOADED WITH SOME OF THE WORLD’S MOST NUTRIENT-DENSE FOODS — Every scoop of this low carb protein powder also has 1000mg of functional mushrooms (chaga extract, reishi extract, turkey tail extract, cordyceps extract, and lion's mane extract), plus 500mg adaptogens (ashwagandha and eleuthero). Together, these miraculous mushrooms and adaptogens provide a plethora of immune boosting, brain balancing, and stress support benefits. - INGREDIENTS WE CAN’T STOP RAVING ABOUT — We’ve packed our organic plant-based protein with only the cleanest protein powders (organic hemp protein powder, organic American pea protein, organic chia, organic pumpkin protein, and organic coconut protein). Each recyclable container provides 15 servings of uninhibited, clean, expertly elevated protein. This is the protein you and your kitchen deserve. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08GN8X844 | | Age Range Description | Adult | | Allergen Information | Peanuts, Tree Nuts | | Best Sellers Rank | #10,178 in Health & Household ( See Top 100 in Health & Household ) #60 in Sports Nutrition Protein Powder Blends | | Brand | Four Sigmatic | | Brand Name | Four Sigmatic | | Customer Reviews | 4.4 out of 5 stars 273 Reviews | | Diet Type | Gluten Free | | Flavor | Peanut Butter | | Item Dimensions | 5.12 x 5.12 x 7 inches | | Item Weight | 600 g | | Manufacturer | AmazonUs/FOUYZ | | Manufacturer Part Number | Plant-Based Protein Pnut Butt 15ser 600g | | Material Type Free | Gluten Free | | Model Name | Four Sigmatic Protein Powder | | Model Number | Plant-Based Protein Pnut Butt 15ser 600g | | Net Content Volume | 21.16 fluid ounces | | Number of Items | 1 | | Package Type Name | R | | Product Benefits | Immune Support | | Protein | 18 g | | Recommended Uses For Product | Immune Support | | Servings per Container | 15 | | Total Servings Per Container | 15 | | UPC | 816897022274 | | Unit Count | 21.16 Ounce | | Vitamins And Minerals | 360, 360 milligrams | ## Product Details - **Brand:** Four Sigmatic - **Flavor:** Peanut Butter - **Item Weight:** 1.55 Pounds - **Material Type Free:** Gluten Free - **Servings per Container:** 15 ## Images ![Organic Plant-Based Protein Powder | Clean Vegan Protein Elevated with Lion’s Mane, Chaga, Cordyceps and More for Brain Function and Immune Support | Peanut Butter, 21.16 oz - Image 1](https://m.media-amazon.com/images/I/71-ApdznoqL.jpg) ## Available Options This product comes in different **Size, Flavor** options. ## Questions & Answers **Q: Where should I start?** A: We recommend starting with the supplement that best suits your routine.
