Sticking to a keto diet is all about keeping carbohydrates low while getting enough protein and healthy fat. For anyone who also eats plant-based, that raises an obvious question: which protein powders are genuinely low in carbs and suitable for keto? Not every vegan protein fits the bill, so this guide rounds up the best plant-based options for a low-carb lifestyle and shows you what to look for on the label.
What makes a protein powder keto-friendly
Before getting to the list, it helps to know what you are aiming for. A keto-friendly protein powder should be high in protein, low in net carbs per serving, and free from added sugars, sweetened syrups or starchy fillers. Many mainstream protein powders, especially meal-replacement and mass-gainer types, hide carbohydrates in the form of oats, maltodextrin or fruit sugars, so the ingredients list is your best friend. As a general rule, the simpler the formula, the better it suits keto.
Pea protein
Pea protein is arguably the most popular plant protein for good reason. Made from yellow split peas, it is naturally low in carbohydrates, high in protein and rich in the amino acids your body needs for muscle repair. Its mild, neutral flavour blends easily into shakes and smoothies, and it is gentle on digestion. For most people following a vegan keto plan, pea protein is a reliable first choice.
Hemp protein
Hemp protein comes from hemp seeds and brings more than just protein to the table. It contains healthy fats and a good dose of fibre, which suits the higher-fat nature of keto nicely. The trade-off is a slightly earthier taste and a marginally lower protein percentage than pea or soya, but as a whole-food style protein with added nutritional benefits, it is a strong contender.
Pumpkin seed protein
Pumpkin seed protein is a quietly excellent choice for keto. It is low in carbohydrates and packed with minerals such as magnesium, zinc and iron. It has a mild, nutty flavour and tends to be easy to digest, making it a good option for anyone who finds other proteins heavy.
Sunflower seed protein
One of the newer options on the shelf, sunflower seed protein is naturally allergen-friendly, which makes it ideal for people avoiding soya or nuts. It is low in carbs, gentle on the stomach and blends well, especially when combined with other seed proteins for a fuller amino acid profile.
Blended plant proteins
Some of the best keto-friendly powders combine several plant proteins in one. A pea and rice blend is a classic, pairing the strengths of both to deliver a complete range of essential amino acids. Multi-source blends of pea, pumpkin, sunflower and hemp are increasingly common and offer a well-rounded, low-carb option in a single scoop. If you want convenience and balance, a blend is often the smart pick.
A whole-food protein to keep alongside
Powders are not the only way to lift your protein on a low-carb diet. Hemp seeds are one of the best whole-food options to keep in the cupboard, naturally high in protein, low in carbohydrates and rich in healthy fats, which makes them a natural fit for keto.
Our Organic Shelled Hemp Seeds have a soft texture and mild, nutty taste, so they are easy to sprinkle over salads, stir into coconut yoghurt or blend into a shake for an extra protein lift. Think of them as the perfect partner to your protein powder.
How to choose the right one for you
The best plant-based protein powder for keto really comes down to your own needs and taste. Check the net carbs per serving and keep them low. Scan the ingredients for added sugars and starchy fillers. Consider any allergies, since soya and nuts are common triggers. And think about flavour and texture, because the powder you enjoy is the one you will actually keep using. It is worth trying a couple of options to find your favourite.
Eating plant-based and keto at the same time is far easier than it sounds once you know which proteins to reach for. Pea, hemp, pumpkin seed and sunflower seed proteins, along with well-made blends, all deliver plenty of protein without the carbs. Read the label, keep the sugars low, and lean on whole-food helpers like hemp seeds to round things out. With the right powder in your routine, you can hit your protein goals and stay firmly in ketosis, all on a plant-based plate.
If you have a health condition or are new to keto, it is always worth speaking to a healthcare professional before making significant changes to your diet.
