Lookin’ pretty decent for a first timer! Here’s a few recommendations I would make after reading over your recipe:
Protein: If you don’t have any adverse reactions to soy products, switching to 85 g of soy protein from True Nutrition would save you $1.40 per day. You can get it flavored any way you like for about $0.15 more per day. The only catch is you gotta buy in bulk to get the best savings!
Fiber: Most bulk stores (like Bulk Barn here in Canada) carry both psyllium husk powder and dextrin for about a quarter of what you’re paying for the name brand super fiber. The benefits of a broad fiber profile aren’t very significant as long as you’ve got both soluble and insoluble sources in your diet.
Carbohydrates: Consider substituting out some of the maltodextrin for some oat flour. Active folks tend to report feeling tired on just maltodextrin, and the oats will give you some fuel for the long-term rather than the short term. If that happens to you, give it a shot.
Fats: Your Omega 3/6/9 supplement is probably unnecessary. A 1:1 blend of olive and canola oils will be good enough and cheaper.
Vitamins and minerals: Consider looking at the Nature’s Way Alive! Liquid Multi-Vitamin. It’s slightly more expensive than your current multi-vitamin and vitamin K supplements ($0.64 per day vs. $0.27), but it’ll top up your niacin, vitamin K, vitamin A, molybdenum, and selenium—all of which you’re a little low on. Plus it’s got some plant bits something or other in it that’s of dubious nutritional value, but hey, it’s there.
Socially Awkward Question: I have to say, 1300 cals per day seems awfully low, even for a 150 cm tall woman. Would you mind if I double checked your numbers? If you’re not comfortable posting your age and weight in a public forum, you can send me a private message and I’ll forget I ever read it after math time is over.
I hope this helps!
