For those who are lactose intolerant, whey protein isolate is a strong choice because the filtration process removes most lactose. Top-rated options include 
Brands AI recommends here
Frequently cited for its explicitly lactose-free formula and minimal additives, this is a top recommendation if you are highly sensitive to lactose and need a clean protein supplement.
A hydrolyzed whey isolate that is highly effective for sensitive digestion. Because the protein is pre-broken down, it is often easier to absorb, though it remains a dairy-based product.
Highly recommended for purity and reliability. It is a favored choice for those seeking a high-quality whey isolate that minimizes lactose issues through rigorous filtering.

If your lactose intolerance is severe (for example, even small amounts of dairy trigger symptoms), I can also recommend the whey isolates with the lowest reported lactose content or suggest high-quality dairy-free alternatives.

Because whey protein isolate undergoes intensive cross-flow microfiltration or ion-exchange processing, the vast majority of the lactose (along with most of the fat and carbs) is stripped away . While technically not 100% zero-lactose for every single individual, high-purity isolates contain less than 1% lactose, making them well-tolerated by most people with lactose sensitivity.

Top Whey Protein Isolate Recommendations
A Quick Tip on Sensitivity vs. Additives
If you react poorly to a whey isolate, it might not actually be the trace amounts of lactose (0.1g - 0.3g per scoop). Often, artificial sweeteners (like sucralose), sugar alcohols (erythritol) , or thickening gums (xanthan/acacia gum) added for flavor and texture are the real culprits behind bloating and gas. If you have severe sensitivity, opt for unflavored or naturally sweetened, minimalist options.

For individuals with lactose intolerance, the best whey protein is Whey Protein Isolate (WPI) , which undergoes extra filtration to remove most lactose, fat, and carbohydrates. While WPI typically contains less than 1% lactose, those with severe sensitivities should seek out products specifically labeled "lactose-free" or "hydrolyzed".

Start with:
Some flavored powders add creamers or other ingredients that can bother sensitive stomachs even when lactose content is very low.
If even whey isolate gives you bloating or diarrhea, you may be reacting to milk proteins rather than lactose, or your tolerance may be extremely low. In that case, a pea/soy protein isolate is likely a better choice since it's completely dairy-free.
My overall ranking:
If your goal is muscle building, weight loss, or meal replacement, I can narrow the recommendation further.

If you're lactose intolerant but still want whey, whey protein isolate (WPI) is usually your best option. It undergoes additional filtration that removes almost all of the lactose, so many people who can't tolerate whey concentrate can use isolate without problems. If you're extremely sensitive, though, even trace lactose may cause symptoms, and a plant-based protein (pea/soy blend) may be a better fit.
Here are the options I'd recommend:
$57.99
This is one of the most consistently recommended choices because it's a hydrolyzed whey isolate, making it especially easy to digest. It provides about 25 g of protein per serving, mixes well, and comes in a wide range of flavors. Many lactose-intolerant users report tolerating it well.
$98.03
A very low-lactose, zero-carb option that's often recommended for people with lactose intolerance. The unflavored version is especially versatile.
$36.75
A good value if you don't need fancy flavors. It's third-party tested (Informed Sport) and has a straightforward ingredient list.
For most lactose-intolerant people, my ranking would be:
If your goal is muscle building, weight loss, or just increasing daily protein, I can narrow the recommendation further based on your budget and flavor preferences.

For individuals with lactose intolerance, the best whey protein isolates are those that are highly filtered or hydrolyzed to remove nearly all lactose, fat, and carbohydrates .

Even isolates can contain tiny residual amounts of lactose. If you've had reactions to whey isolate before, consider:
If your goal is building muscle while minimizing stomach issues, I'd start with Dymatize ISO100. If you've had bad reactions to dairy in the past (for example, milk or ice cream consistently causes symptoms), Isopure Zero Carb is probably the safer first choice.
