Amino Acids

Probably not, and we would rather say so. Protein from food and shakes already contains every amino acid you need. Aminos become useful when intake is low or awkward to plan: a plant-based diet, a small appetite, illness, or training before breakfast. They are also handy when you want a low-calorie drink during a session instead of a shake. If your protein intake is solid, put your money into food or a protein powder first.

It depends on whether you want broad cover or one target.

Powder wins when you need grams; capsules win when you travel.

With free-form aminos, timing is less strict than the label often suggests. They are absorbed quickly, so many people take a blend around training: before, during or straight after. Single aminos are usually spread through the day, or taken away from a large meal so they are not competing with a full load of dietary protein. The most important thing is consistency. A serving you actually take every day beats a perfectly timed one you forget.

Yes, and many people do. A practical approach is one blend as your base and, at most, one or two single aminos with a clear purpose. Keep them apart in the day rather than stacking everything into one scoop, so you can tell what is doing what. Note that amino acids compete for the same transport routes into the body, so very large doses taken at the same moment work against each other. L-theanine, the amino acid from green tea, is often taken separately from training servings.

Most free-form amino acids are made by fermentation, using bacteria fed on plant sugars, so the amino itself is not animal derived. The exceptions are usually in the packaging and extras: gelatine capsules, a whey or collagen base, or dairy-based flavourings. Always check the capsule material and the full ingredient list. On our product pages we state the capsule type, and vegan products are filtered as such so you do not have to guess.

Daily use at label doses is common and generally well tolerated. The complaints we hear most are practical rather than serious: bloating, loose stools, or a bitter taste when a large dose is taken at once on an empty stomach. Splitting the serving or taking it with a little food usually solves it. If you are pregnant, breastfeeding, take prescribed medication, or have kidney or liver problems, check with your doctor first, since protein and amino load is relevant in those situations.

Because the EU only permits health claims that have been assessed and authorised, and individual amino acids such as leucine, glutamine or arginine do not have approved claims for muscle or recovery. Protein does have an authorised claim, which is why protein powders may say more than an EAA powder. We keep to those rules on purpose. It means we describe the form, the dose and how people use a product, and we leave the promises to others.
