# Leucine, Protein Distribution and the Breakfast Problem

> The same amount of protein, distributed differently across the day, yields up to 25% more muscle protein synthesis. What lies behind it - and why WOO® Vegan Walnuss Ahornsirup is a morning product.

Most people eat the bulk of their daily protein in the evening. Breakfast is carbohydrate, lunch is thin, and at seven in the evening the big portion arrives. For muscle, that is the worst of all distributions - and the reason lies in the physiology of muscle protein synthesis.

## Muscle protein synthesis counts servings, not daily totals

Mamerow et al. (2014) compared two groups with an identical daily protein intake: one spread evenly across three meals, one loaded towards the evening. The even distribution produced roughly 25% higher muscle protein synthesis over 24 hours. The amount was identical - only the timing differed. The reason: every meal triggers its own synthesis burst that lasts a few hours and then tails off. A single mountain of protein in the evening cannot retroactively fill the windows you missed.

## Leucine is the switch

Not every amino acid matters equally. Norton and Layman (2006) described **leucine** as the signal that initiates translation in the muscle cell. Below a certain amount of leucine per meal the switch stays off; above it, it flips on. This is precisely where plant proteins historically had their weakness: leucine content is lower in many plant proteins than in whey. [WOO® Vegan Walnuss Ahornsirup](/en/shop/woo-vegan-walnut-maple-syrup-can) addresses that directly - according to the product data, leucine accounts for more than 8%. At 31 g of protein per serving that is around 2.5 g of leucine, in the range the literature discusses as effective.

## Why three components beat one

Gorissen et al. (2018) analysed commercially available plant protein isolates and showed how differently the amino acid profiles turn out: pea protein is rich in lysine but weak in methionine; with rice protein it is the other way round. Combine them and the gaps close each other. Pumpkin seed protein adds further profile and fatty acids. Pinckaers et al. (2021) summarised the evidence on the anabolic response to plant-based protein: the gap to animal protein can largely be closed through quantity and smart combination. The three-component principle of pea, rice and pumpkin seed is therefore not a marketing idea but an answer to an amino acid problem.

## WOO® Vegan Walnuss Ahornsirup in the morning

One serving is 30 g of powder with 31 g of protein and only 1.4 g of carbohydrate. Protein contributes to the maintenance and growth of muscle mass and to the maintenance of normal bones. The walnut-maple syrup flavour is deliberately not fruity: it fits exactly the meal that contains the least protein for most people. Stirred into muesli, mixed with water or with fruit juice, a carbohydrate breakfast becomes a meal with around 30 g of protein. The 800 g tub covers 20 servings - at one serving per morning, just under three weeks. 100% vegan, lactose- and gluten-free.

## Frequently asked questions

**How much protein do I need per meal?**
As a rule of thumb, 0.4 g per kilogram of body weight per meal, spread over three to four meals. The official baseline recommendation for adults is 0.8 g per kilogram per day; athletes sit well above that.

**Why not simply eat more in the evening?**
Because synthesis saturates per meal. Mamerow et al. showed exactly that effect: same amount, different distribution, markedly more synthesis.

**Does it work in muesli or a smoothie too?**
Yes, WOO® Vegan Walnuss Ahornsirup is explicitly intended for muesli as well. Mixed with fruit juice you also get carbohydrate for the start of the day.
