Efectiv EAA With 8g Essential Amino Acids and 3g Leucine
Efectiv Nutrition EAA delivers a full-spectrum essential amino acid profile at 8g EAA per 12.5g serving, including 6g BCAA in a 2:1:1 ratio. Each serving provides L-Leucine 3000mg, L-Isoleucine 1500mg, L-Valine 1500mg, L-Lysine 700mg, L-Threonine 500mg, L-Phenylalanine 400mg, L-Methionine 200mg, L-Histidine 100mg and L-Tryptophan 100mg, plus potassium 190mg, magnesium 68mg and vitamin B12 2.5mcg. The 375g tub provides 30 servings at 10 calories.
Essential amino acids cannot be synthesised by the body and must come from diet or supplementation. The nine EAAs in the formula are the complete set: all nine are required simultaneously for muscle protein synthesis to proceed at maximum rate. Leucine at 3000mg provides the primary mTOR activation signal that initiates protein translation. The remaining EAAs provide the substrate pool for the elongation and completion of new protein chains. Tryptophan is included in this formula, unlike some EAA products that omit it to avoid post-workout drowsiness; at 100mg the dose is too low to generate significant serotonin load in most users. The electrolyte addition makes the formula serve as a dual protein-hydration intra-workout.
What separates Efectiv EAA from a BCAA product is completeness. BCAAs (leucine, isoleucine, valine) account for 40% of the essential amino acid requirement but the remaining six EAAs are also required for protein synthesis. A BCAA-only product initiates mTOR signalling but cannot complete the protein chain without the full EAA set from food or supplement. An EAA formula eliminates this bottleneck during fasted or low-protein-intake training windows.
Efectiv EAA suits fasted morning trainers, athletes training in a calorie deficit where habitual protein intake may fall below optimal, endurance athletes with multi-session training days needing rapid inter-session recovery, and anyone who wants intra-workout amino acid support without a heavy protein shake. It is not a protein supplement replacement for those meeting total daily protein targets through whole food and whey. Contains no major allergens.

Frequently Asked Questions
What is the difference between EAAs in Efectiv EAA and BCAAs?
BCAAs cover three amino acids: leucine, isoleucine and valine. EAAs cover all nine essential amino acids your body cannot produce on its own, including the three BCAAs. Research suggests all nine EAAs are needed to fully stimulate muscle protein synthesis. Efectiv EAA provides the full 8g spectrum with 6g of BCAAs inside it, so a separate BCAA product is not needed alongside it.
When should I take Efectiv EAA during training?
Most people sip Efectiv EAA during the workout to support working muscles in real time. Mix one scoop with 500ml of cold water and drink across the session. EAAs also work post-workout for recovery, or between meals when you want amino acid support without the calorie load of a full shake. Each serving is just 10 calories.
Do I need Efectiv EAA if I already use whey protein?
Whey protein already contains all nine essential amino acids, so if you consistently hit your daily protein target, a separate EAA product is a nice-to-have rather than essential. Efectiv EAA is most useful during training when a full shake feels too heavy, during fasted sessions, or when you want amino acids at a low 10-calorie cost.
None. Produced in a facility that handles milk, soya, egg and gluten.
