Best Healthy & Tasty Protein Powder (Sugar-Free)

10 months ago (edited)

Hi everyone!

I’m looking for a high-quality protein powder with flavor that meets the following criteria:

✅ Zero sugar - Naturally sweetened with stevia or erythritol (no artificial sweeteners like sucralose or aspartame)

✅ Clean ingredients and easy on digestion

✅ Ideally organic or third-party tested

Open to both Whey Isolate (if ultra-clean) or plant-based options (e.g., pea, rice, hemp blends).

👉 Curious to hear what you use and love — especially in terms of taste, mixability, and gut tolerance.

Thanks in advance for your recommendations!

Whey Protein:
I can highly recommend Sunday Natural’s Bio Whey Protein Santo Domingo Cacao. It blends rich Santo Domingo cocoa with high-quality organic whey, delivering a complete amino acid profile, without added sugar, sweeteners, or artificial ingredients. Just clean, honest fuel for your muscles, perfect for anyone serious about recovery and strength.

Personally, I love the taste: slightly bitter and great mixed with berries, nuts, or yogurt.

Plant Based Protein:
For me, Sunday Natural’s Vegan Protein 3K Intense Vanilla is the best-tasting vegan protein powder out there. This smooth blend of fava beans, peas, and sunflowers delivers all essential amino acids, zero artificial additives, and a naturally delicious vanilla flavor, ideal for anyone training hard or just looking for a clean, plant-based protein boost.

My personal favorite is Volksshake's Bio Natur Vegan Protein. It contains 10 different protein sources - which is really important when using plant protein - and almost 80% pure protein, made in Germany and tastewise my favorite protein powder, no (artificial) sweeteners, organic and has a pretty good amino acid profile as well.

I am with @karol when it comes to vegan protein powders - Sunday's Vanilla is the best. Very creamy, matching whey protein consistency as no other vegan one I know. <3

I‘m using Vivolife Perform Vanilla as my default plant based protein supplement (monthly subscription). Tastes great, natural and no animals get hurt 😎https://www.vivolife.de/products/perform?variant=39658760831039&country=DE&currency=EUR

I use the protein powders from

Vetain. Especially the banana flavor is pretty nice if mixed with some frozen berries and some nut milk.

Hi everyone!

Thanks so much for the great input on clean, flavored protein powders! 🙌 One follow-up question: Has anyone tried blending whey protein with plant-based protein?

I’m considering this combo to get the best of both worlds – and would love your thoughts. From what I understand:

  • Whey has a complete amino acid profile and fast absorption

  • Plant-based proteins (like pea, rice, hemp) are often easier on digestion and bring extra fiber and nutrients

👉 So combining them could support muscle building, gut health, and longevity goals even better?

If anyone has experience with this or a go-to blend they recommend (including flavored, sugar-free options), I’d love to hear.

Thanks again Zapiens! your input is incredibly helpful.

@ronald-tenholte Interesting! Thanks! Why do you think the amount of many different protein sources in vegan protein is important?

@brgmn Great question. A lot of plants have an incomplete amino acid profile. That doesn't mean they don't have all 20 AA (incl. the 9 essential ones) - all plants do, contrary to what some people claim online. It rather means: If you got all your protein from this one plant (whichever it may be), you'd be deficient in certain AA. For example, Chick Pea Protein (and its isolates) is low in methionine, so you need to add other plant proteins that cover the requirements for methionine like oats or other grains. If you rely on only a few plant protein sources, you risk chronically undersupplying specific AAs, even if total protein intake is high.

In the past few years animal protein has been consistently linked to chronic disease like Diabetes, CVD, cancer, cognitive decline and premature deaths in several large studies (e.g. Korat et. al., 2024, AJCN).

At the same time, different studies have found that above 1.3-1.4g Protein per kg BW, there were no significant benefits of animal protein over well-balanced plant protein with regards to strength and hypertrophy.

If you are indifferent to whether to take animal or plant protein, from a longevity perspective I would highly recommend plant protein to avoid the excessive intake of certain AA that are believed to be the cause of the aforementioned risk of chronic disease.

@ronald-tenholte What do you think about the amino acid profile of Vivolife Perform plant protein (attached)? Seems to work fine for me. Also had a look at https://volksshake.de/shop/bio-natur/ but was a bit worried about sunflower seed protein (omega-6?). Maybe I should just test this out...

@brgmn Actually, I'd prefer Vivolife with respect to longevity goals. I only use a shake about once a week, that's why I am fine with/looking for the considerably higher amounts of BCAA in Volksshake. That way I have a once-per-week increase in BCAA/mTOR and get better performance outcomes without sacrificing too much of my longevity goals the other 6 days of the week. If using on a more regular basis, I'd opt for Vivolife - if that makes sense.

As for sunflower seed oil: The pro-inlammatory narrative around omega-6 is actually not backed by any studies. Quite the contrary, there is tons of data showing that omega-6 lead to less inflammation and - more importantly - better cardiometabolic outcomes, better lipid profiles and hard health outcomes like lower risk of all-cause mortality; e.g. from a large meta-analysis:
"No significant effect of higher LA [Linoleic Acid = Omega-6] intake was observed for cytokines: tumor necrosis factor, interleukin-6 and monocyte chemoattractant protein 1 [...] C-reactive Protein concentration was not significantly affected by increasing LA intake" (https://pubmed.ncbi.nlm.nih.gov/28752873/). So no rise in inflammatory markers.

Noone knows why this narrative sticks, but the evidence is actually quite clear: As long as you get enough of the Omega-3 DHA & EPA (fish or supplemenation), Omega-6 poses no risk and rather supports good health.

@karol Those are my go-to ones, too.

I think we have to keep in mind that most studies that favor vegan vs animal options are not testing protein powders but the overall diet, and that included animal fats and so on. Some studies are based on questionnaires.

Both types of powders seem fine, but in general for very high consumption vegan powders bring more heavy metals into your system.
