Optimum Nutrition Gold Standard 100% Casein Protein

This supplement is a protein powder designed to promote recovery and growth after exercise, while you sleep, and throughout the day. It contains micellar casein for slowly absorbed amino acids that continue to be delivered into your bloodstream for several hours. This means a constant supply of nutrients that aid in recovery and muscle building. 

Optimum Nutrition also added glutamine peptides, which also aids in the regeneration of cells from damage done during intense training sessions. There are no artificial colours or flavours used, so it has a smooth, creamy texture with vanilla flavour mixed in with other add-ins. It comes in one large jug containing 32 servings, giving you a great value per dollar spent on the product.

10 Grams of Essential Amino Acids

Amino acids are the building blocks of protein, so this supplement has an excellent supply to keep you repairing and growing.

Enhanced with patented Digestive Enzymes

This is great because it helps your body absorb more of the nutrients to be used effectively on muscle growth and repair. You will benefit from using this consistently as it gives you better results over time.

24g of Anti-Catabolic Micellar Casein

Muscle wasting is when there's a breakdown of muscle tissue due to excessive damage done during training sessions, lack of nutrition, and other factors which cause the body to break down muscle tissue instead of building it up. With micellar casein, you get an optimal dose for repair and growth because every gram contains glutamine peptides; this gives it high anti-catabolic properties, which help prevent or reduce the rate at which muscle is broken down while you sleep, work and throughout the day.

Slow-Digesting Protein

Casein protein is a very slow-digesting protein that provides a steady supply of amino acids to your muscles for several hours. This means you can build muscle 24/7 whether you're working out or not.

Using a slow-digesting protein like this not only provides essential amino acids to your muscles but also prevents muscle breakdown, so you get the most out of every gram. This gives you excellent results over time with consistent use.

5 Grams of Naturally Occurring BCAAs

Branched-chain amino acids - leucine, isoleucine and valine - are essential for keeping your body anabolic all day long during periods where you aren't training and especially overnight while sleeping. They prevent muscle wasting and ensure that your body still gets enough nutrients for tissue repair and growth, even if you're eating or drinking anything. 

5 Grams of Naturally Occurring Glutamine and Glutamic Acid

The body uses glutamine to produce other amino acids, which helps keep your muscles growing even if you're not training.

9 Grams EAAs

Essential amino acids - leucine, isoleucine, valine, lysine, histidine, phenylalanine and methionine - play a vital role in muscle growth and development since they are the building blocks needed to repair and grow tissue. They also form enzymes that help with metabolism, so you get more value from everything you eat throughout the day. 

Low Sugar

Since sugar can prevent or inhibit weight loss goals while trying to achieve a lean physique having low levels ensures that you stay on track towards your goals. 

Chocolate Supreme Flavour

Most people like this flavour because it is very delicious, and the taste lasts for a long time; you can dictate how fast or slow it melts in your mouth depending on what you want.

Suggested use:

Add 1 scoop to 8-12 oz. of cold water or skim milk in a shaker cup until dissolved and shake for about 10 seconds. Make sure to drink this with 8 ounces of water shortly before working out, within an hour after training, or before bedtime so that you get the most results possible from consistent use. Do not exceed recommended amount since using more won't provide additional benefits - stick to the suggested daily dosage of one serving per day for maximum results.

This is amazing

I use both the ON whey and casein, and the casien is my favourite. I love it because adding a scoop really fluffs up my shakes. The flavour is fantastic and I love how smooth, thick, and creamy it makes my protein shakes. I much prefer the chocolate over the vanilla flavour, as the vanilla one tastes too fake/sweet.
