Blueprint Bryan Johnson Nutty Butter – Chunky Macadamia Nut Butter with Walnut – No Palm Oil, No Added Sugar – Just 3 Ingredients – Keto, Vegan, Paleo – Low Carb Nut Butter Snack – 8.8oz Jar

This was delicious, much better than Peanut Butter which makes my arthritis flair up. Peanuts are very inflammatory. I wish they made a bigger size but it's probably good that they don't. I think I would eat the whole container. It's hard to stop eating it. It's got a lot of crunchy nutty pieces in it so if you like creamy you may not like this. I taste more of the Macadamia nuts than the Walnuts. The oil does separate on the top but it's not hard to mix it together once it is opened. I think it's a little expensive for the small amount that you get but currently nuts are very expensive. I would buy this again but not right now due to the price and the fact that I can't stop eating it.

Really good and different!

I’m a big fan of what Bryan Johnson is doing to push the boundaries of human health and longevity. His mission is inspiring, and I want him to keep pushing forward. That said, this particular product—Nutty Butter—feels like it hit the shelves before it hit the mark. Let’s start with the positives: macadamia nuts and walnuts are nutritional powerhouses. Macadamias are rich in monounsaturated fats that support heart health and may help reduce inflammation. Walnuts are packed with alpha-linolenic acid (ALA), a plant-based omega-3 fatty acid shown in recent studies to support brain function and cardiovascular health. Together, they make a compelling duo for anyone chasing optimized performance and long-term wellness. But here’s the issue—and it's a big one. My jar had a large piece of plastic along with several smaller plastic shards, and what looked like sharp walnut shell fragments. That’s a serious safety concern, especially from a brand built on precision and data-driven quality. The flavor and texture? Pretty solid. Slightly oily, but the nut blend delivers a rich, earthy taste that you don’t usually get from mass-market nut butters. With a little more refinement and better quality control, this could be a game-changer. I’m rooting for Bryan and the Kernel team, but Nutty Butter isn’t ready for prime time just yet. I’ll be watching for version 2.0.

I don’t normally review items on Amazon, but I felt I needed to with this one since it doesn’t seem to get enough love! First of all - I follow a keto diet, and I’ve had sensitivity issues with foods the last few months, so I’ve been very careful about what I include in my daily diet. I’ve been avoiding nut butters, but knowing the amount of research and testing that goes into these Blueprint products, I felt safe choosing this nutty butter as a little snack/dessert. It was AMAZING! Full of flavor and soooo delicious and decadent tasting (however, don’t expect peanut butter!! It’s macadamia nut and walnut- more similar in flavor profile to almond butter, but slightly more mild). I love it and ate almost the whole jar in three days. The best part for me? The fact that it’s high fat and low carb, and also not terrible calorie-wise. But the low carb part definitely had much appeal for my diet and lifestyle. Thank you, Bryan Johnson, for yet another wonderful Blueprint product!!

I’ll start by saying it’s delicious and meets the nutritional requirements I was looking for. Yes, it’s pricey, but I don’t mind paying for a quality product from a trusted brand. It keeps in the pantry, oil separation is expected and easily remedied. Now, the reason for three stars… in nearly each serving, I’ve crunched down on a piece of walnut shell and wondered if I should have my dentist on speed dial. If you’re willing to screen for these shell fragments, don’t let this review discourage you from trying this, as it has a wonderful nutritional profile and is a fabulous substitute for peanut butter. Hope this helps!

Tastes good, but has a typical natural oily consistency that requires a lot of stirring. The small jar does not make that easy. I'd rather have this than the artificial ingredients companies use to make standard butters creamy, but it sure would be great just to be able to open this, spread it, and eat it. Are there no natural food products that would create that creamy consistency?

When I first opened it, I was not impressed- it looked pretty gross. But the instructions say to mix before use and after a thorough stir, it developed into a nice crunchy peanut butter texture. Taste is very palatable, low sugar, and not as overpowering as peanut butter. I compared separately purchasing Walnut Butter + Macadamia Nut Butter, and this product is a better value. Macadamia is what makes it so expensive. I haven't taken the time to read up on the specific reasons for these ingredients. When comparing to low sugar peanut butter, the peanut butter has similar Nutrition Facts, but I know that this product was designed to go deeper. I'm pleased to add this to my Subscribe & Save routine. (On a separate note, I recommend buying a wooden spoon / stirring utensil. Metal + plastic containers don't 'mix' well. I'd be much more comfortable if this came in a glass jar and I'm surprised that it doesn't especially given Blueprint’s health focus.)

Very tasty and nhealthy - except for the broken teeth you'll get if you bite into one of the 8 shell pieces in the jar. Be careful!
