BCAAs (Branched-Chain Amino Acids) bring together three essential amino acids the body cannot make on its own: leucine, isoleucine and valine. The 2:1:1 ratio, with leucine as the dominant amino acid, matches the natural distribution of these amino acids in human muscle. Each 4-capsule dose provides 1,200 mg of L-leucine, 600 mg of L-isoleucine and 600 mg of L-valine — 2,400 mg of pure BCAAs obtained through 100% plant-based biofermentation.

Unlike most amino acids, which pass through the liver, BCAAs are metabolised directly in muscle. They play a central role in muscle protein synthesis, post-exercise recovery and limiting catabolism (muscle breakdown) during and after training. Leucine is the amino acid most involved in activating the mTOR pathway, which initiates muscle protein synthesis.

The 2:1:1 ratio replicates the natural balance of BCAAs in human muscle tissue. Some manufacturers offer 4:1:1 or 8:1:1 ratios with an even higher leucine proportion, but these formulations have not shown additional benefit in the scientific literature — in fact, excess leucine without enough isoleucine and valine can reduce overall assimilation efficiency. International recommendations converge on the 2:1:1 ratio to meet muscle needs during sustained physical activity, the most studied dosage and the one offering the best compromise between protein synthesis stimulation, recovery and digestive tolerance.

Dynveo’s BCAAs are obtained through biofermentation from plant-based raw materials, unlike classic BCAAs often derived from animal by-products (feathers, hair). This process guarantees highly pure amino acids, fully vegan and free from animal-derived contaminants. Biofermentation is now recognised as the cleanest method for producing amino acids, giving a product free from GMOs, allergens (gluten, lactose, soy), excipients and nanoparticles. Dynveo’s production is ISO 9001, ISO 14001 and ISO 22000 certified, with verifiable anti-doping compliance.

Take 4 capsules a day (2,400 mg of BCAAs) with a large glass of water, ideally before or immediately after training. This dose can be increased up to 8 capsules (4,800 mg) during intensive training phases, under the guidance of a healthcare professional or sports nutritionist. The capsules can be taken all at once or split across the day; people training multiple times a day may find splitting the dose morning and evening useful. The 180-capsule bottle covers a month and a half at the standard dose of 4 capsules a day.

Do not exceed the recommended daily dose without medical advice. People with kidney conditions should consult their doctor before any amino-acid supplementation. Not recommended for pregnant or breastfeeding women. Food supplements should not replace a varied, balanced diet and a healthy lifestyle. Vegan product, GMO-free, gluten-free, lactose-free, soy-free, no nanoparticles, no colouring or preservatives. Vegetable pullulan capsules. Biodegradable, compostable bottle. Certified anti-doping compliant.

BCAA capsules offer practical advantages: precise dosing, easy to carry, no bitter taste — suited to people wanting a quick, discreet dose with no preparation, each capsule providing exactly 600 mg of BCAAs. BCAA powder allows more flexible dosing and larger servings (up to 6 g per serving), preferred by athletes who mix their BCAAs in a shaker with other supplements. Both formats contain exactly the same amino acids, from the same biofermentation process.

What is the best time to take BCAAs?

The ideal time is just before or immediately after training, during the anabolic window when the body best assimilates nutrients. Before exercise, BCAAs prepare the muscle and limit catabolism; after exercise, they support muscle rebuilding.

Why prefer a 2:1:1 ratio over 4:1:1 or 8:1:1?

The 2:1:1 ratio matches the physiological composition of human muscle. Higher ratios (4:1:1, 8:1:1) increase the leucine proportion without documented additional benefit. The 2:1:1 balance remains the one recommended in the scientific literature for complete assimilation and optimal effectiveness.

Are there any contraindications for vegan BCAAs?

Vegan BCAAs from biofermentation, formulated with no allergens or excipients, are generally very well tolerated. Follow the recommended daily dose. People with kidney conditions should consult a doctor before amino-acid supplementation. This product complies with anti-doping standards.

What supplements pair well with BCAAs?

BCAAs combine well with organic plant proteins, Creapure creatine and algae-derived omega-3s for a complete sports programme. Adding PeptiStrong reinforces the effect on muscle synthesis. Adjust dosages to your profile and goals.
