So I googled huel just to get to the forums and check out any new news and stumbled upon this from Myprotien
looks like they have made a version similar to yours
"Vegan protein and carbohydrate powder blend with pea protein, flaxseed, brown rice protein and vitamins & minerals, various flavours with sweetener. Fortified food."
a 5kg bag is £47 which is 6 meals shy of the £86 on offer from you guys.
“Vanilla Flavour: Oat Flour (41%), Pea Protein Isolate (23%), Vegan Vegetable Creamer (Sunflower Oil, Emulsifiers (Acacia Gum, Sunflower Lecithin), Brown Rice Syrup, Natural Flavourings, Anti-Caking Agent (Silicon Dioxide), Antioxidant (Alpha-Tocopherol)), Brown Rice Protein (6%), Natural Vanilla Flavouring (Flavourings, Sweetener: Sucralose), Flaxseed Powder (5%), Potassium Phosphate, Calcium, Emulsifier (Xanthan Gum), Vitamin and Mineral Mix (Sodium Fluoride (Carrier: Sweetener [Mannitol]), Maltodextrin, Vitamin C, Zinc, Iron, Vitamin E, Niacin, Sodium Selenite (Carrier: Calcium Carbonate), Vitamin A, Copper, Manganese, Pantothenic Acid, Biotin (Carrier: Maltodextrin), Chromium (Carrier: Calcium Carbonate), Folic Acid (Carrier: Maltodextrin), Vitamin D (Ergocalciferol), Vitamin B6, Vitamin B12 (Carrier: Maltodextrin), Vitamin K, Potassium Iodide (Carrier: Sodium Citrate), Thiamin, Molybdenum (Carrier: Maltodextrin), Riboflavin), Inulin Powder, Magnesium, Thickener (Guar Gum).”
I do not want to shit on your parade but it looks very similar for a huge difference in price…
