Lactose is a natural sugar present in milk. The inability of the digestive system to break down this lactose sugar is referred to as lactose intolerance. About 65% of individuals around the world are lactose intolerant (1).

The smallest quantity of milk or lactose in food may trigger digestive disturbances in lactose intolerant people, such as nausea, excessive gas, bloating, feeling of being full, and even abdominal pain.

Regular milk-based protein powders pose a problem to such lactose intolerant people and hence, lactose-free protein powders are a major boon to them.

We have picked six of the best lactose-free protein powders available in the market for you to choose from.

1. Best Lactose-Free Protein Powder using Rice Protein- SPORT Protein Oryzatein®

Brown Rice Protein is an excellent protein alternative for individuals sensitive to dairy and egg protein. Brown rice protein may be equally effective as whey protein, in fat loss and muscle protein synthesis (2).

The great thing about brown rice protein is its intermediate rate of absorption, which is between a fast-digesting whey protein and a slow-digesting casein protein. It’ll keep you feeling full for a longer time (compared to whey) without the initial hunger associated with casein protein.

The manufacturing process is completely chemical-free and uses only natural enzymes and low heat. The product is vegan, gluten-free, and dairy-free.

Oryzatein® rice protein boasts of a 30% increase in the uptake of leucine when compared to whey. Leucine is an essential amino acid responsible for kickstarting muscle protein synthesis. Another constituent, the probiotic Bacillus coagulans optimizes the protein absorption quality.

Overall, Oryzatein® rice protein can improve muscle strength and power by promoting vigorous muscle growth and recovery. It also builds up endurance and athletic abilities.

SPORT Protein Oryzatein® is a non-GMO, gluten-free supplement with natural sweeteners and Himalayan pink salt which is a great source of potassium, magnesium, and sodium.

The suggested serving for this protein powder is 2 scoops, mixed with 200-450 ml of water. It should be taken either as a pre-workout supplement (2-3 hours before) or immediately post-workout.

Since brown rice protein is completely organic, it is naturally low in calories. Unlike dairy proteins, it does not cause any insulin spikes in the body and protects against unnecessary weight gain (3).

Dosage Instructions for Lactose-Free Protein Powders

Dosage instructions for lactose-free protein powders are similar to regular protein powders.

The Recommended Daily Allowance (RDA) of a normal adult is 0.8 g per kilogram of the body weight. So if an individual has a bodyweight of 65 kg, they need to take 0.8 x 65 = 52 g of protein daily to maintain healthy body functions.

This, however, is not the case for physically active individuals or those with higher protein requirements, such as pregnant and lactating women, infants, children, and aged individuals.

Having a medical condition also increases the body’s daily protein requirement. It’s interesting to note that these values aren’t different for males or females. It’s solely based on the grams per kilogram of body weight, irrespective of gender.

The recommended protein dosage does vary if your daily energy expenditure is significant, as in the case of performance athletes. Within the category, factors like the type of athletic activity, exercise intensity and duration, age, and goals (either weight loss or weight gain) also determine the RDA.

Generally, for endurance athletes like marathon competitors, the RDA is between 1.2 – 1.4 g/kg body weight and for power athletes like weightlifters, the RDA is between 1.2-1.7 g/kg of body weight.

We generally do not consume as much protein as we should on a daily basis, so there’s always room to up your protein intake. According to Harvard Health, taking up to 2 g/kg of body weight daily is safe (6).

Post-workout intake of protein powders is a great way to supply muscles with the required protein. But, it’s important not to take your entire dose of daily protein in one go. It’s best to pace your protein intake throughout the day.

Summary: Recommended daily allowance of protein for a healthy adult is 0.8 g/kg body weight. The RDA becomes higher in physically active individuals (more in power athletes than endurance athletes), pregnant and breastfeeding women, and the elderly.

Side effects and Risks of Using Lactose-Free Protein Powders

Although there is an ongoing debate about potential side effects and risks associated with the long-term use of protein powders, there is no real scientific evidence supporting the claims.

Normal individuals with healthy body function can safely tolerate whey (or any other type of protein powder) within the recommended dosage without fear of significant health risks.

However, certain stomach problems such as constipation, diarrhea, bloating may occur if protein supplementation is not carried out properly.

Constipation: A commonly stated side effect is constipation but one must realize that it is not a direct result of taking protein powders. Constipation occurs in individuals who use protein powders as a meal replacement option and do not include whole fruits and vegetables in their diet. This results in a lack of dietary fiber which causes constipation symptoms.

Diarrhea: Another common side effect of lactose-intolerant individuals is diarrhea. This may be because of the presence of lactose in an impure or low-grade protein blend, coupled with a lack of dietary fiber from whole foods.

Sodium Content: Plant proteins like pea, hemp, soy, and rice protein are generally well tolerated. But some grades of pea protein powder are high in sodium (some of them contain up to 110–390 mg sodium per serving of protein) so it’s important to look up the nutritional labels before purchase.

High Fiber: If hemp protein is consumed very quickly or too much at once, some individuals may suffer from bloating, diarrhea, or gas because it contains a higher amount of fiber than other plant proteins.

Some research also suggests that pregnant and breastfeeding women, people with blood anemia, or those with an immune-compromised condition should avoid hemp protein but further clinical trials on humans need to be held to confirm the risks (7), (8).

Bad Breath: If protein intake is quite high and the carb intake is low, individuals may experience something called ketosis, where there is a deficiency of carbs in the body. Protein is broken down in the body to release energy which produces certain ammonia compounds, they give a fruity odor or bad breath from the mouth.

The Risk to Kidneys: Although too much protein cannot damage the kidneys of healthy people, individuals with existing kidney disease may need to limit their intake (9), (10). There could be a predisposition to developing kidney stones in such people.

Individuals taking a high protein diet with a lot of saturated fats may also have a greater risk of developing heart disease or colon cancer, compared to a high protein diet from plant sources which may not pose such a risk.

Summary: When protein powders are taken as meal replacements, without adequate fiber in the diet, symptoms such as constipation, diarrhea, and bloating may occur. Protein intake must be spaced out throughout the day and higher consumption of protein may cause bad breath due to ketosis.

Frequently Asked Questions (FAQs)
