The science

Rubisco, explained.

The most abundant protein on Earth sits inside every green leaf. It is complete, it digests fast, and until now nobody could produce it at scale. Here is what it does and how we know.

The speed

Built to absorb during, not after.

Most protein is built for recovery, which is why it digests slowly over hours. Under the internationally standardised INFOGEST model, three quarters of the protein in Blade is broken down inside five minutes of gastric digestion and it is effectively gone by thirty. Whey, tested under identical conditions, is still 64% intact at the hour mark.

The amino acids

522 mg of EAA per gram. More than whey.

All nine essential amino acids, every one of them above the FAO/WHO adult requirement per gram of protein, and 196 mg of BCAAs per gram including 86 mg of leucine: the trigger for muscle protein synthesis.

More than whey (516), egg white (486), soy (407), pea (404). 196 mg of that is BCAAs, including 86 mg leucine.

The iron pairing

Iron that comes from the leaf.

Blade's iron is naturally occurring and retained from the leaf, held in association with protein rather than added as an inorganic salt. It arrives with vitamin B2 in the same sip, a nutrient with a recognised role in iron metabolism. Nothing fortified, and gentle on the stomach.

What iron supports, that active people feel first

Oxygen transport to working muscleEnergy production and metabolismReduced tiredness and fatigueRed blood cell and haemoglobin formationNormal cognitive functionImmune system support

Established roles of dietary iron (Institute of Medicine, 2001). Product-specific effects need human evidence.

6 mg

naturally occurring iron per 100 ml Blade

58% of the NZ/AU daily reference intake, 35% of the US daily value, in a form the body meets as food rather than a supplement.

Whether some of that iron sits in plant ferritin, and what that means for tolerance and uptake is an open research question. Phytoferritin can hold iron in a soluble, protected form; we are studying how much of Blade's iron arrives that way.

Iron, from the leaf

6 mg

per Blade

Naturally occurring, protein-associated iron with B2 in the same sip. Supports oxygen transport, energy and reduced fatigue.

Vitamin B2 · riboflavin, 3.3 mg. Energy metabolism, and the vitamin that helps the body use iron.

Vitamin B7 · biotin, 10.8 µg. Part of normal macronutrient metabolism.

Vitamin K1 · phylloquinone, 20 µg. The green-leaf vitamin, for clotting and bone.

The full panel

Every nutrient, from one leaf.

Protein, minerals and vitamins, and not one of them is fortified, synthesised or added back in. This is simply what the alfalfa leaf already carries.

The micronutrients

The leaf keeps more than protein.

Because Blade is pressed from a whole leaf rather than isolated to a powder, a set of naturally occurring vitamins comes through with the protein. Nothing added back, nothing synthetic.

Vitamin B2

Riboflavin · 3.3 mg

A cofactor in turning carbohydrate, fat and protein into energy, and the one with a recognised link to iron: it supports iron metabolism and the intestinal tissue that absorbs it (Aljaadi et al., 2023; Powers, 1995). This is why iron and B2 arriving together matters.

Vitamin B7

Biotin · 10.8 µg

Part of normal macronutrient metabolism, helping the body draw energy from the food around it. Naturally present in the leaf and retained through extraction.

Vitamin K1

Phylloquinone · 20 µg

The plant form of vitamin K, abundant in green leaves and central to normal blood clotting and bone maintenance. A marker that this really did come from a leaf.

Whole-leaf matrix

Iron, B2, B7 and K1 together

Delivered in the same food, the way the plant made them, rather than fortified into a base. The case for eating the leaf, not just its protein.
