This has a nice texture and a milky vanilla taste with a bit of yogurt "tart". Note that the small amount of sucralose (Splenda) is needed for good taste...it gives a more rounded taste. Likewise, the vanilla is not just a flavor, it's essential to rounding out the taste.

If you want to use natural vanilla rather than imitation there are powder sources which cost more. Imitation vanilla is the main organic compound found in vanilla.

Celebrating 10 years (2025) of updated recipes! My recipes are some of the top ones listed on this site. Please go to my website diyfoods.org for the latest on:

  • recipes
  • research notes
  • analysis showing complete protein amino acid profiles achieved
  • ingredient links
  • samples
  • instructions for use
  • mixing calculators

After 2025 I will no longer update ingredient purchase links here because with several recipes it's too much work. I will keep the recipes themselves up to date here as long as this site functions. Often the editing tools on this site go down. But at diyfoods.org you can be sure you're getting the latest info.

See all my recipes: Oat-Rice, Oat-Whey, Oat-Wheat, Corn-Oat-Wheat, and High Protein Wheat. They each taste very different and offer complete protein. Samples are available for some. I also developed a simple solid soylent for activities like backpacking and cycling tours.

Background

In 2014 my family used official Soylent (now Complete Foods) versions 1.1 through 1.4 for about 5 months, about 2 meals a day. As an incurable do-it-yourselfer and a scientist, I couldn't help researching nutrition and experimenting with my own recipes which I knew I could make much cheaper than commercial meal replacements. I matched the official Soylent nutrition, and found sources to buy ingredients at low cost by buying in bulk. In Feb 2015 my rice protein recipe was a hit with the family, who said it tasted better than the official product at the time. I developed other recipes, and now rotate between recipes.

Lots of mistakes Many nutrients missing from key items meaning you are likely over dosing on some vitamins And... How can there be 80 grams of protein in 56 grams of whey? If you are only consuming 56 grams of 80% whey protein, that means you are only getting 44.8 grams of protein per day with this recipe..

I have no other versions to compare to but here goes. I mixed my first batch last night. I had to do some math as I only got the 1 vanilla so made 90 days worth of vitamins. The items round off to a tbsp. of vitamin mix for me, 2 tbsp. splenda, and 1 tbsp. of sugar...slightly heaping. Oil, oats, whey, 4 cups water and poof a days worth, resulting in 2 liters. I chilled for a few hours and had a glass in the evening. I blended on medium in my vitamix. When making soup I have created foam when used to high, but pureed all things to liquid, so didn't want to over aerate the first batch. On medium I got a gritty drink what I compared to a malt. The recipe as far as I am concerned is great considering. I had no issue drinking it down. I did find myself wanting to chew while drinking at this consistency. I could taste a hint of the salt but more of a bran type flavor, completely tolerable. I didn't feel like I was forcing liquid cardboard down, and had no issue drinking another in the morning with my coffee. I am a one meal a day person for a few reasons, and this is my attempt to correct this. I found myself hungry within 4-5 hours from the breakfast serving. When I got home I finished what was in the container, about 1.5 of the glass I had had before. I did get hungry later and ate an apple and small snack. But feel fine. I don't feel bloated or other side effects. It was said it takes a bit to get use to it, but where my palette may not be refined, I didn't have any issue right off. I have seal-a-meal containers that are perfect for one days worth of the non-vitamin dry ingredients so I only have to add the spoon full of vitamins, liquids, and the rest of the premade mix. Tomorrows mix I used only 3 cups of water, but mixed on high. Figured I can always add more water. Would suggest.
