As of Jul 2026, Unbox Health has lab tested and rated 14 products in the Plant Protein Powders category.
We buy every product from the open market, with no brand involvement. Every product is tested at up to 3 NABL-accredited labs. Products are then rated D to A+, based on the following dimensions: their label accuracy, their toxicity and their nutritional profile (in the case of food products). All lab reports are published.

Plant protein powder is a concentrated supplement made from sources like pea and brown rice isolate, typically delivering 60 to 78g protein per 100g. It can be a useful way for vegetarians and vegans to meet protein needs. ICMR-NIN recommends meeting protein through whole foods like dal and legumes first, using powders only to fill genuine gaps.
Yes, plant protein can build muscle as effectively as whey when total daily protein and resistance training are adequate. A 2023 review in Sports Medicine found no significant difference in strength or muscle size between pea and whey users. Plant proteins are lower in leucine, so pea and brown rice blends help create a more complete amino acid profile.
Pea protein contains all nine essential amino acids, so it qualifies as a complete protein, though it is relatively low in methionine. This is why most Indian plant protein powders blend pea with brown rice, which is higher in methionine, to balance the amino acid profile. For vegetarians, a pea and rice blend closely matches the quality of animal protein.
Plant protein, especially pea and rice isolate, is generally well tolerated and low in fiber, so it causes less bloating than whole legumes. Some people may still experience gas or mild discomfort, often from residual fermentable carbs or added ingredients like inulin. Starting with a smaller serving and increasing gradually usually helps your gut adjust within a week or two.
Plant protein is safe for most healthy adults, but pea and rice proteins can absorb heavy metals like lead and cadmium from soil, sometimes at higher levels than whey. Rice protein is especially prone to this. Levels vary widely between brands, so check Unbox Health's lab-tested data to verify whether a product's contaminant levels fall within safe limits.
Current evidence has not shown plant protein to impair kidney function in healthy individuals at normal intakes. However, people with existing kidney disease should be cautious and seek medical guidance, as they may need to limit protein. Those with chronic kidney conditions, or anyone advised to restrict protein, should consult a doctor before using any protein supplement regularly.
ICMR-NIN sets the protein RDA at 0.83g per kg of body weight daily for healthy Indian adults, so a 60kg person needs about 50g total protein from all sources. Active individuals and those doing resistance training may need 1.2 to 1.6g per kg, per international sports nutrition guidance. Use powder only to bridge the gap your meals leave.
Timing matters less than hitting your total daily protein target. That said, many people take plant protein within a couple of hours after a workout to support muscle recovery, or between meals to stay full. Because plant proteins digest slightly slower than whey, a serving at breakfast or before bed can also work well for steady amino acid supply.
Not always. Protein content can vary between the label claim and what a product actually delivers, and some brands use cheaper fillers or amino spiking to inflate numbers. Indian plant proteins commonly claim 60 to 78g protein per 100g. Check Unbox Health's lab-tested results to verify whether the declared protein content matches what independent testing actually found.
Look for a pea and brown rice blend for a complete amino acid profile, minimal added sugar, and a clean ingredient list without unnecessary fillers. Prioritise brands that publish heavy metal and protein content testing. Compare which brands actually deliver the protein they claim and stay within safe contaminant limits using Unbox Health's independent lab-tested ratings before you buy.
