It should also be noted that the figures for 1.9 are assuming that the batch is only at the specified level. Each batch of pre-mix I get comes with a Certificate Of Analysis (COA) that gives the actual amounts in that specific batch. They tend to have a higher amount, especially for the vitamins that oxidize quicker to build in some longevity. After the “best used by” date you might be getting a little bit less of certain vitamins but not much less. In case you are curious and want to check it out, here is the COA for the batch of pre-mix I just received. This may be of interest to people in light of a recent reddit post on the subject of micronutrients.
An additional change I’m doing with 1.9 is making MCT optional in the preparation instructions (it’s still awesome for Keto though, so I recommend it if your bowels tolerate it). Because creating a custom vitamin pre-mix and ordering several hundred kilograms is outside a normal DIY recipe, I’m going to leave the recipe for 1.5 alone and fork the recipe for 1.9 over to a new location. Feel free to continue making your own 1.5 – it’s not going away. 
Chris Bair created Keto Chow to simplify getting good nutrition for "I just need food" meals, focusing on the best available proteins, vitamins, and minerals to save mental energy for important things. You don't have to be doing keto to use Keto Chow but it does make keto easier. In 2023 Chris created SALTT Electrolytes ('salty') as an alternative to existing electrolytes that contained questionable ingredients, like maltodextrin, and didn't align with what he wanted in an electrolyte supplement. The number 1 best seller is the unflavored Clean Slate.
