Optimum Nutrition BCAA 1000

BCAA 1000 contains a potent balance of BCAAs which are building blocks of muscle

BCAA 1000 contains a potent balance of Branched Chain Amino Acids which are building blocks of muscle mass and size. Metabolized directly in the muscle, BCAAs, may improve nitrogen retention by sparing other amino acid groups for repair and rebuilding. The Branched Chain Amino Acids (BCAA's), so named because of their unique branched chemical structure, are essential in that the body cannot make them from other compounds. In recent times, these amino acids have been investigated for their potential anti-catabolic (preventing muscle breakdown) and anabolic (muscle building) effects.

Q (1)When is the best time to take this on an empty stomache or with a meal?? (2)can this also be taken with protein shake post workout or would that be pointless because protein shake is pretty much the same ??

Consume 2 BCAA 1000 capsules between meals, 30-45 minutes before workouts, and/or immediately after workouts for best results.

Q can i combine this with musclepharm creatine 300 and Optimum Nutrition Gold Standard 100% Whey 4.5kg ?

Yes. perfectly fine.

Q Does BCAA have any side effects?

There are no side effects to using BCAA's

Q Hi i weigh 72kg and i am trying to build six packs and muscle.I am taking tonalin CLA and omega 3 1 capsule each after dinner.I am thinking of adding a protein shake or BCAA .Please advice me which one should i prefer and also whether it is good to combine with CLA and omega 3 ?

If you are going for just the one then i'd go for the protein shake such as 100% Gold standard whey because this will have added BCAA's in it along your protein. They are also fine to combine with cla and omega-3.

Q Hi, I am about to add "Optimum Nutrition BCAA 1000 Caps 400ct" in my daily routine and wondering if you can guide me if its ingredient meets my requirement. If the product is suitable for vegetarians than its ok for me but if it is not then I want to confirm followings. Basically I am looking for a “Hillal” product. In case if you are not familiar with term “Hillal” then here is the definition. If it passes the below mentioned requirements then I will consider it “Hillal” and it will be ok for me. Product do not include Swine/pork and its by-products * Animals improperly slaughtered or dead before slaughtering * Animals killed in the name of anyone other than (God) * Alcohol and intoxicants * Carnivorous animals, birds of prey and land animals without external ears * Blood and blood by-products * Foods contaminated with any of the above products

This contains gelatin from either cow or pig origin, so is not Hallil. With capsules, unless they say "Vegi Cap" or something similar, assume they are from animal sources.

Q hi, i was wondering will EAA and BCAA products be effected by the VAT ???

No, these products already have VAT applied so prices will not change on Oct 1st

Q i am on a fat loss lose fat and acheive lean muscular build...i workout on a regular basis especially with weights and i often notice muscle breakdown and loss of muscle density in the long-term....will this product help me to build muscle definition and stop muscle breakdown like i seem to naturally do ???

You should take some whey protein and/or a BCAA product like this or an Essential Amino Acid (EAA) product (like EAA Stack) before and after training. Also, take a protein supplement between meals and with meals and snacks that are low in protein and drop some of your carbs if you are worried about the added calories. Higher protein diets definitely work better for fat loss and for maintaining mass whilst cutting

Q Im planning to take this with Growth Matrix or One Stop Nutrition (Reflex) will this be over doing it? Considering both products are all in one sort of thing. I'l also be taking Reflex Omega 3. Does this sound decent to you, or is there anything you would recommend or change? Not very muscly at the moment but plan is heavy weights with high intensity cardio. To gain muscle while burning fat. Thanks

No, this is a great stack to take. Just make sure you use the BCAA upon waking, before training and before bed.

Q Is it safe to use it together with Grenade Thermo Detonator ? If so how can I take them ?

Yes - Thermo Detonator is a fat burner, which can safely and effectively be used in conjunction with BCAAs. Both should be taken in accordance with their product's guidelines.

Q Hi, Which gelatin type do you use for capsules from animal or plant, If it is from animal, which animal do you supply from? Thanks.

Gelatine is a constituent ingredient of the outer coating of Optimum Nutrition BCAA 1000 capsules. I am unsure of which animal(s) this is sourced from.  For more clarification, I would advise that you contact Optimum Nutrition directly. You can contact a Customer Care Representative via this email address:, or alternatively, by calling: 0345 688 5120.
