Warnings
It is recommended to take 1 sachet per day, dissolved in 300ml of water. Supplements should not be considered substitutes for a varied diet. Do not exceed the recommended doses. Keep out of reach of children under 3 years of age. In case of hypersensitivity or allergy, avoid using the product. Do not use in case of thyroid dysfunction. Store in a cool, dry place.

Longevity-aligned
Low methionine, sufficient leucine the macro profile linked to longer healthspan in Longo Lab research.
Lean-mass support
14 g of complete plant protein per sachet designed for patients at risk of sarcopenia after age 65.
Single-serve clarity
Pre-portioned bustine. No scoops, no guesswork useful for adherence in clinic-managed protocols.
How it fits the protocol
Between FMD cycles. In the over-65 cohort, daily.
01
Post-FMD recovery
One sachet on day 7 (post-refeed) supports lean- mass return. Particularly important for over-65 patients where rebound protein matters.
02
Sarcopenia at-risk
Daily sachet for patients aged 65+ or with documented appendicular lean-mass loss. Above- threshold leucine, low methionine — the safe- side macro.
03
Plant-protein gap
For vegan and Mediterranean-leaning patients whose total daily protein consistently lands under 1.0 g/kg. One sachet closes the gap.
What's in the sachet
14 g complete plant protein —engineered for the Longo macro rules.
Pea and brown rice are blended in a 65/35 ratio to close the amino-acid profile while keeping methionine intentionally low — the protein shape associated with longevity in both animal and human studies.
PER SACHET
9 g
Pea protein isolate
Pisum sativum · 85% protein
The dominant plant protein in the blend. Naturally high in arginine and lysine, low in methionine — the profile linked to lower IGF-1 in Longo Lab research. Complete digestibility (PDCAAS) when paired with brown rice.
PER SACHET
5 g
Brown rice protein
Oryza sativa concentrate
Pairs with pea protein to close the methionine + cysteine gap and complete the amino-acid profile (PDCAAS ≈ 1.0). The whole-grain origin also contributes B- vitamins and a mild caramel note to the chocolate sachet.
PER SACHET
2.5 g
Leucine threshold
2.5 g leucine / sachet
Above the 2.3 g leucine threshold needed to trigger muscle protein synthesis in older adults. Important for the sarcopenia-risk cohort — the single most under- served indication in the over-65 metabolic patient.
PER SACHET
—
Cocoa + mineral matrix
Cocoa, calcium, magnesium, iron
Natural cocoa for the chocolate flavour (no artificial sweeteners), plus a baseline mineral matrix that addresses the most common deficiencies seen in plant- protein diets — iron (4.2 mg) and B12.
Amino-acid profile · per 22 g sachet
Sufficient leucine.
Intentionally low methionine.
Whey hits leucine harder but at the cost of methionine — an amino acid that activates IGF-1 / mTOR pathways implicated in accelerated aging. L-Protein keeps leucine above the muscle protein synthesis threshold while staying low on methionine, on purpose.
Methionine
L-Protein 0.18 g · Whey 0.45 g · per 14 g protein
Leucine
L-Protein 2.5 g · Whey 2.4 g · both above MPS threshold
Arginine
L-Protein 1.4 g · Whey 0.4 g · plant-protein advantage
Biological Age Score · Nature Aging, 2024
Three cycles. 2.5 years younger, on the data.
In the Mishra et al. 2024 trial (n=144, RCT), patients completing three consecutive Prolon FMD cycles reduced their Levine PhenoAge by an average of 2.5 years versus controls.
