Q: What's the best keto-friendly protein powder in Canada?
A: Allmax Isoflex — 27g whey isolate, only 2g carbs, 0g sugar, 0g fat per serving. Sweetened with sucralose + acesulfame potassium. Cleanest macros for ketogenic diets.
Keto diets demand precise macro tracking. Most whey concentrates pack 4-6g carbs per scoop (acceptable for relaxed keto, problematic for strict). Whey isolates filter most carbs out — Isoflex at 2g carbs per 32g scoop fits even strict 20g daily carb limits.

What to Look For
- Net carbs matter: total carbs minus fiber and allulose. Isoflex 2g total carbs = 2g net carbs.
- Avoid maltodextrin: some "low-carb" proteins use it as filler — high glycemic, kicks you out of ketosis.
- Sweetener choice: sucralose, stevia, monk fruit, erythritol = keto-OK. Sucrose, agave, honey = no.
- Mass gainers and whey concentrate: usually too high-carb for strict keto. Skip those.
Frequently Asked Questions
Can I have whey protein on keto?
Whey isolate is fine for keto due to low carbs. Whey concentrate (more carbs) works for relaxed keto but may be too high for strict <20g daily.
Will protein kick me out of ketosis?
Excess protein can convert to glucose via gluconeogenesis at high doses. Up to 30g per meal is typically fine. Keto purists prefer protein-moderate, fat-heavy meals.
How do I count Isoflex's 2g carbs?
Standard keto counting: subtract fiber, sugar alcohols, and allulose. Isoflex's 2g are total carbs (low). At 2 scoops daily = 4g carbs.
What about MCT oil?
MCT (medium-chain triglycerides) is a keto staple — fast-burning fat for energy. Works alongside protein. Different category.
Will Isoflex taste artificial?
Sucralose-sweetened proteins range from very-good (Allmax) to chalky (cheap brands). Isoflex tastes clean. Try a sample if you're particular.
