BCAA's Per Serving
Branched-chain amino acids, or BCAAs, are a subset of Essential Amino Acids, these are proteins your body does not produces so you need to add it to your diet.Three of the nine EAAs are considered BCAAs - leucine, isoleucine, and valine.

The BCAA - Leucine is the most potent activator of protein synthesis & you need at least 2 -3 g to stimulate protein synthesis in your body.
13 100% Whey has 3,13g of Leucine per serving, perfect to het the most out of your protein.
Digestive Enzymes
Tolerase L, is a digestive aid for people who suffer from lactose intolerance. Tolerase L is an acid lactase that converts lactose, a milk sugar naturally present in dairy products, into glucose and galactose. Around half of the world’s population are lactose intolerant and do not produce any or sufficient quantities of lactase, leading to discomfort including bloating, gas, diarrhea and abdominal cramps once the undigested lactose reaches the large intestine. Tolerase L acts at a low pH to digest lactose in the stomach and relieve these symptoms.

Nutrition Facts

Isolate Vs Concentrate

Isolate is highly filtered to make sure you get 90% protein content per scoop. This means it’s a lean protein, less carbs, fat & basically free of lactose.

Concentrate is less filtered & more full bodied, meaning it has some healthy fats & carbohydrates to help with muscle building.

do it right

When & How Much

How much Protein do you need?

Muscle maintenance- The rule of thumb is 1 g of protein per kg of preferred body weight for muscle maintenance ( meaning, you weigh 75kg’s , but your ideal is 70kg’s, so you’ll try & get 70g of protein per day. )

Muscle building - You need to start increasing your daily intake to between 1.5g - 2g of protein per kg body weight.

Thus, a 80kg male that wants to build muscle, needs to get up to 160g of protein per day to build lean muscle.

When Should I Take Protein?

It’s simple.Think every 4 hours!

MPS ( Muscle Protein Synthesis ) get stimulated through Leucine in your protein! When you have 20 - 30g complete protein at a sitting, you’’ll have enough to Leucine to take MPS over the edge. Once it’s spiked you there’s a refractory period of 4 hours where you cannot spike MPS.

So for optimal performances & gains, you need to get at least 3g of Leucine from your protein, every 4 hours over your 16 hours day!

Perfect Protein Plan:

1 - Get enough protein per meal (20 - 30g)

2 - Every 4 hours to spike MPS

3 - Thats 3 meals plus an extra shake. Simple

Customer Reviews

Overall rating: 4.8 / 5 from 141 reviews.

The best quality product on the market. As someone who struggles with an IBD and sensitive gut, finding a quality whey protein that is easy on the stomach felt impossible. That was until I discovered 13 Nutrition. The product is premium quality and really easy on the gut. Been using it for probably a year now, and still going.
