Graded honestly
What the evidence says
A vegan chocolate protein powder made from fava bean protein isolate, fermented yeast protein and cocoa: 21 g of protein and 110 calories per 34.7 g serving. The label also lists 1 mg of iron and 2 mcg of vitamin D. Protein is needed to build and maintain muscle, and in trials extra protein gave a small added gain in strength and lean mass during resistance training, mainly when the diet was short of it. This blend has not been tested in a training study, and the one trial of fava protein on its own did not raise muscle protein building.
How it works
Protein from food is broken down into amino acids, which muscle uses to repair and build its own proteins. Resistance exercise makes muscle more responsive to these amino acids for a day or so afterward. The essential amino acid leucine acts as the trigger, and all nine essential amino acids are needed as raw material. Plant proteins generally have less leucine than dairy protein and can be less digestible, so gram for gram they may trigger a smaller response; a higher total protein intake can make up the difference.
The dose in this product
One serving a day gives 21 g of protein. Per meal: guidance for stimulating muscle protein building is about 0.25 to 0.3 g of high-quality protein per kg of body weight, or 20 to 40 g, containing 0.7 to 3 g of leucine.
How that compares with the studiesHide the comparison
One serving sits at the low end of that range. Plant proteins generally have less leucine than dairy, and older adults need more protein per meal for the same response, so a larger or older person may do better pairing a serving with other protein foods. The label allows one serving a day.
Per day: the adult RDA is 0.8 g per kg of body weight; people in regular training are advised to get 1.2 to 2.0 g per kg, and trials found no further gain in lean mass above about 1.6 g per kg. The average American man already eats about 100 g of protein a day and the average woman about 69 g. Supplement trials averaged 36 g a day, more than this product's 21 g.
Quality: the supplier has not published the blend's amino acid profile, its leucine content or the ratio of fava to yeast protein, so statements such as 'complete protein' cannot be confirmed. In the one fava trial the protein was about 8 percent leucine; at that rate a serving would hold about 1.7 g. Timing: the label says to take it 20 to 30 minutes before a meal.
Nothing in the research reviewed supports that; a meta-analysis cited by the NIH found that taking protein within an hour of exercise did not add strength or size, so your daily total matters most.
- Moderate evidence
Protein contributes to the growth and maintenance of muscle
This is a well-established nutrient function: the NIH describes protein as necessary to build, maintain and repair muscle, and the essential amino acids it supplies must come from the diet. One serving provides 21 g of protein. [1]
- Moderate evidence
Extra protein supports small added gains in strength and lean mass from resistance training when your usual intake is below about 1.6 g per kg of body weight a day
A meta-analysis of 49 randomized trials (1,863 people) found protein supplements added about 2.5 kg to one-rep-max strength and 0.3 kg of fat-free mass over training alone, with no further gain above about 1.6 g of protein per kg a day in total. The trials averaged 36 g of supplement a day (range 4 to 106 g) and mostly used whey or milk protein, so 21 g of a fava and yeast blend is only a partial match; hence moderate, not strong. [2]
- Early evidence
Plant proteins can support training gains close to those of animal proteins when total protein intake is adequate; this fava and yeast blend is untested
A meta-analysis of 16 trials found no difference between plant and animal protein for gains in absolute lean mass or strength, though animal protein did slightly better for percent lean mass and in adults under 50; the plant proteins were soy, pea and rice, not fava or yeast. In the one fava trial, about 23 g did not raise muscle protein synthesis above a control drink of non-essential amino acids in 16 adults, and a 6-month trial of yeast protein in 92 older adults found no change in muscle mass or grip strength. [4][5][6]
Strong evidence: many human trials agree, at the amount in this product. Moderate evidence: human trials mostly agree, but they are small, short or mixed. Early evidence: a few small human studies or lab work. Promising, not proven.
Safety
Who it is for, and who should ask first
Do not use if
- You have G6PD deficiency (favism), unless your doctor says it is safe. Fava beans can cause red blood cells to break down in people with this condition.
Good fit if
- Vegans, vegetarians and people avoiding dairy or soy who struggle to reach their protein target
- People doing resistance training whose usual protein intake is below about 1.6 g per kg of body weight a day
- Adults of any age who eat little protein and do strength exercise (older adults may need more protein per meal)
- Not needed if you already eat enough protein: more than that did not add muscle in trials
Ask your doctor first if
- You are nursing a baby who has, or may have, G6PD deficiency
- You are pregnant or nursing
- You are under 18
- You have kidney disease or have been told to limit protein
- You are allergic to peanuts, soy, peas, lupin, lentils or other legumes, or to yeast
- You take levodopa or an MAO inhibitor
Interactions
- Levodopa: amino acids from protein compete with it for absorption and for transport into the brain. Ask your doctor how to time protein.
- MAO inhibitors (such as phenelzine): these medicines require limiting tyramine, which is found in certain beans and in fermented yeast products. The tyramine content of this powder is not known, so ask your pharmacist.
Possible side effects
- None known at recommended protein intakes, according to the NIH fact sheet
- Allergic reactions are possible in people sensitive to legumes or yeast
- In people with G6PD deficiency, fava beans can cause red blood cells to break down
Upper limit
No upper limit has been set for protein. The NIH reports no safety concerns at intakes up to about 2.0 g per kg of body weight a day and notes that high-protein diets do not appear to compromise kidney function in healthy people. The label limit is one serving (2 scoops) a day.
The 1 mg of iron per serving is 6 percent of the Daily Value.
Combining with our other products
Collagen Peptides (18 g of protein per serving) and Colostrum add to your day's protein total; Colostrum is a milk product and is not vegan. BCAA 2:1:1 adds little on top of a protein serving, which already contains those amino acids. Creatine has no overlap with this product.
Sodium: each serving has 190 mg (8 percent of the Daily Value); with Creatine + Electrolytes (1,000 mg, 43 percent) that is about half the Daily Value from supplements alone. Vitamin D: count this product's 2 mcg toward your total if you also take Vitamin D3 (50 mcg), Immune Support (40 mcg), Ashwagandha Complex (20 mcg) or Men's Multi (10 mcg); see the Vitamin D3 page for the upper limit.

Answers
Questions people ask
Is 21 g of protein enough per serving?
It is at the low end of the 20 to 40 g that sports nutrition guidance suggests per meal. Plant proteins usually have less leucine than dairy, so a larger person or an older adult may want to pair it with other protein in the same meal. What matters most is your total for the day.
Is plant protein as good as whey for building muscle?
Over weeks of training, pooled trials found no difference between plant and animal protein for strength or absolute lean mass, with a small edge for animal protein on percent lean mass and in adults under 50. Gram for gram, plant proteins tend to trigger a smaller short-term response, which a higher total intake can offset. This fava and yeast blend has not been tested in a training study.
How much protein do I need in a day?
The adult RDA is 0.8 g per kg of body weight. For people in regular training, guidance is 1.2 to 2.0 g per kg, and trials found no further muscle gain above about 1.6 g per kg. The average American man already eats about 100 g a day and the average woman about 69 g, so check your diet before adding a supplement.
Is this a complete protein?
That cannot be confirmed yet. The supplier has not published an amino acid profile for the blend. In the one trial of fava protein, it was low in the amino acid methionine. The yeast protein in the blend may help, but the ratio is not disclosed.
Who should not use fava bean protein?
People with G6PD deficiency, also called favism. Compounds in fava beans can cause red blood cells to break down in people with this inherited condition, and mothers nursing a baby with G6PD deficiency should avoid fava beans too. The level of these compounds in this product is not stated, so avoid it unless your doctor clears it.
Does this powder contain heavy metals?
Plants, including cocoa, take up small amounts of lead and cadmium from soil, so plant protein powders tend to carry more than dairy-based ones. In Consumer Reports' 2025 tests of 23 protein products, plant-based ones averaged nine times the lead of dairy-based ones, chocolate and vanilla flavors had similar average lead levels, and more than two-thirds of all products had more lead per serving than its 0.5 microgram a day level of concern. Those levels are far below what causes immediate harm; the concern is daily use over years, above all for people who are pregnant or may become pregnant. The manufacturer's report on file for this product measures lead, cadmium, arsenic and mercury. The lab report section of this page says what that report covers.
Why is there an iron warning on a protein powder?
The chocolate flavor lists 1 mg of iron per serving, 6 percent of the Daily Value. No iron ingredient is added; it comes from the food ingredients. The warning is standard FDA wording for iron-containing supplements, written with iron tablets and capsules in mind. The amount here is small, but keep the tub away from young children, as with any supplement.
Is extra protein hard on the kidneys?
Not in healthy people, according to the NIH: high-protein diets do not appear to compromise kidney function. If you have kidney disease, protein limits are part of your care, so ask your doctor first.
