Does protein timing really matter? Research suggests the impact may be smaller than many believe. According to House of Hypertrophy, “I am skeptical that there’s anything special about casein.”

Their analysis focuses on protein intake before sleep and indicates that, at best, the effect may be marginal. So what does the evidence actually show? Let’s break it down.

What does the research say?

A study conducted by J Sci Med Sport in 2021 showed that taking 20-40 grams of Caesin 30 minutes before bedtime can be very effective for muscle protein synthesis in a night's sleep, or muscle recovery.

Another study published on PubMed back in 2023 states, “Protein ingestion prior to sleep increases both mitochondrial and myofibrillar protein synthesis rates during overnight recovery from exercise.”

The study concluded that consuming 45 grams of whey protein right before bed, immediately after evening exercise, would support a large peak in blood amino levels, thus aiding recovery.

The Effects on Body

Protein consumed late in the day is digested and absorbed by the body during sleep, with amino acids distributed into the bloodstream.

Let’s take an example: while you rest, the whey you consume works more effectively for recovery. Why? The simple answer is a lack of muscle activity. This helps conserve energy, which in turn allows for better repair and recovery.

A study published in The Journal of Nutrition asserts the same, as it states: “Protein ingestion before sleep represents an effective dietary strategy to augment muscle mass and strength gains during resistance exercise training in young men.”

Now, this raises an important question: will consuming protein before bed affect your sleep?

Well, the answer is a big-fat no. No study or research paper shows any indication that protein intake before bedtime amounts to bad sleep.

Tips

• Aim to have 20-40 grams of protein before bedtime
• Make sure to keep the intake light
• Remember, the most important factor is how much protein you consume.
