What's Inside NutraBio Base Aminos

Essential Amino Acid Matrix — 10g, All Nine EAAs, Fully Disclosed

The nine essential amino acids are the ones your body cannot synthesize on its own and must obtain from food or supplementation. All nine are present and individually disclosed in Base Aminos — no hiding doses inside a proprietary blend, no stacking two or three EAAs and calling it a complete formula. This is the NutraBio standard applied to amino supplementation: if it is on the label, the exact dose is on the label.†

• L-Leucine — 3,000mg — the dominant BCAA and the primary activator of mTORC1 signaling — the cellular pathway that initiates muscle protein synthesis. Leucine functions as the "trigger" amino acid: research demonstrates that leucine is the key rate-limiting factor for anabolic signaling, and that a threshold leucine dose is required to meaningfully stimulate MPS. At 3g, Base Aminos delivers leucine above the threshold most research uses to document significant MPS activation. Every other amino in the formula builds on this leucine foundation.†
• L-Isoleucine — 1,500mg — the second BCAA, important for glucose uptake by skeletal muscle cells during exercise and for supporting energy availability within working muscle. Also participates in MPS initiation alongside leucine, though with less potency than leucine alone.†
• L-Valine — 1,500mg — the third BCAA, primarily involved in glycogen synthesis and energy metabolism during endurance-focused exercise. Valine is thought to support stamina by contributing to glycogen resynthesis when muscle glycogen stores are depleted. Also plays a role in reducing serotonin uptake in the brain during exercise, which may support the perceived reduction in fatigue during prolonged sessions.†
• L-Lysine — a ketogenic essential amino acid with a broad role in muscle protein synthesis, immune function, collagen production, and injury recovery. Lysine is also a core component of the carnitine shuttle system — the molecular mechanism responsible for transporting long-chain fatty acids into the mitochondria for oxidation. Its role in collagen synthesis makes it particularly relevant during phases of heavy training where connective tissue is under increased stress.†
• L-Threonine — precursor to glycine and serine, two amino acids essential for muscle tissue development. Threonine independently supports collagen synthesis and immune function, and synergizes with methionine to support fat metabolism. Among the non-BCAA EAAs, threonine is one of the most important for connective tissue health and structural protein synthesis.†
• L-Phenylalanine — the EAA that supports catecholamine production — dopamine, epinephrine, and norepinephrine — the neurotransmitters and hormones responsible for mood, motivation, and the adrenergic response during intense training. Also serves as a precursor to tyrosine, which then feeds into the catecholamine synthesis pathway. The "mood" amino acid in the EAA profile.†
• L-Histidine — precursor to carnosine, the intramuscular acid buffer that delays the hydrogen ion accumulation responsible for muscular fatigue during high-intensity training. This is the same buffering mechanism targeted by beta-alanine supplementation, but through the direct carnosine precursor route rather than the indirect beta-alanine conversion pathway. Also involved in anabolic signaling pathways and hemoglobin synthesis.†
• L-Tryptophan — the EAA precursor to serotonin and melatonin. Serotonin plays a role in mood regulation and perceived exertion during exercise, while melatonin governs sleep quality and recovery. Adequate tryptophan ensures the amino acid profile supports both training performance and the recovery cycle that follows.†
• L-Methionine — the sulfur-containing EAA that serves as a methyl donor in dozens of enzymatic reactions, participates in protein synthesis initiation, and works alongside threonine to support fat metabolism. Also a precursor to cysteine, which the body uses to produce glutathione — the primary endogenous antioxidant.†

Why All Nine EAAs Matter — The BCAAs-Only Problem

For years the supplement industry sold BCAA products as the amino acid solution — leucine, isoleucine, and valine, and nothing else. The clinical reality is that BCAAs consumed in isolation cannot sustain meaningful muscle protein synthesis because MPS requires all nine essential amino acids as building blocks. When only BCAAs are supplemented, the body is forced to break down existing muscle protein to source the remaining six EAAs — which partially defeats the purpose of the supplementation. Research consistently shows that EAAs as a complete set produce approximately twice the muscle protein synthesis response of BCAAs alone. Base Aminos provides all nine, at a 10g total dose that covers both the leucine threshold for MPS activation and the complete amino acid pool required to actually build muscle protein.†

Taurine — 1,000mg

Taurine is the osmolyte amino acid that sits at the intersection of hydration, endurance, and cellular protection. As an osmolyte, taurine draws water into muscle cells, supporting intramuscular volume and hydration during training. It also plays a role in calcium signaling for muscle contractions, antioxidant protection against exercise-induced oxidative stress, and cardiovascular function. Multiple studies have documented taurine's ability to delay time to exhaustion and reduce perceived exertion during prolonged training. At 1g, Base Aminos provides a meaningful dose that meaningfully supports the hydration matrix alongside the electrolytes.†

Electrolyte Hydration Matrix — 475mg

Sweat depletes sodium, potassium, magnesium, and calcium — the minerals that govern fluid balance, muscle contraction signaling, and nerve transmission. Without electrolyte replenishment during training, performance degrades progressively as dehydration accumulates. The 475mg electrolyte matrix in Base Aminos is calibrated for intra-workout hydration support alongside the amino acid delivery, making it suitable for sipping during training sessions rather than just before or after.†

AstraGin (Panax notoginseng + Astragalus membranaceus)

AstraGin is the patented absorption-enhancing complex from NuliV Science that selectively upregulates intestinal absorption of amino acids, vitamins, and other nutrients. The mechanism involves enhancement of transporter protein expression in the intestinal epithelium — the proteins responsible for actively importing amino acids from the GI tract into the bloodstream. In practical terms, AstraGin ensures the 10g of EAAs you consume actually makes it into systemic circulation at the rates required to support muscle protein synthesis rather than being partially wasted in the GI tract.†

Frequently Asked Questions About NutraBio Base Aminos

1. What makes Base Aminos different from a standard BCAA product?
   BCAA products provide only three of the nine essential amino acids — leucine, isoleucine, and valine. This is sufficient to stimulate the initial signaling for muscle protein synthesis, but the body cannot complete MPS without all nine EAAs as building materials. When you take BCAAs alone, your body sources the missing six from muscle protein breakdown — partially counteracting the point. Base Aminos provides all nine, meaning the full MPS process can proceed without the body cannibalizing muscle tissue to source the missing aminos. The research is clear on this: complete EAA formulas produce meaningfully better muscle protein synthesis outcomes than BCAAs alone. Base Aminos is a complete EAA formula with BCAAs embedded inside it at clinical doses — not a BCAA product with a few extra amino acids sprinkled in.†
2. When should I take Base Aminos?
   Base Aminos is designed for flexible use: before, during, or after training — or between meals to maintain amino acid availability throughout the day. The intra-workout use case is the primary design intent: sipping Base Aminos during training delivers EAAs to muscle tissue during the period when protein breakdown rates are highest, directly counteracting the catabolic environment of intense exercise. The electrolyte matrix and taurine are specifically included to support hydration during the training session. Post-workout use supports the recovery window when muscle protein synthesis rates are elevated. Between-meal use maintains what is called a "net positive nitrogen balance" — an anabolic state in which the body has more amino acids available than it is breaking down.†
3. Why does NutraBio use fully disclosed doses instead of proprietary blends?
   NutraBio was founded in 1996 on a single principle: every ingredient and every dose should be disclosed on the label. This was a radical position at the time — most brands in 1996 used proprietary blends to hide doses that were too low to do anything meaningful but looked impressive in the ingredient list. NutraBio's founder Mark Glazier built the brand around the opposite position: if the dose is not effective, it should not be in the formula. If it is in the formula, the dose should be disclosed. Every NutraBio product including Base Aminos carries this standard — full label transparency, no blends, no hidden doses, no excipients or fillers. You know exactly what you are getting and exactly how much of it.†
4. Can I stack Base Aminos with other NutraBio products or with protein shakes?
   Yes — Base Aminos is designed to complement the NutraBio lineup cleanly. It stacks naturally with protein powder (adding EAA support before or during training while protein handles the post-workout window), with NutraBio Intra Blast for athletes who want a higher-dose intra-workout amino formula for extended training sessions, and with any pre-workout since Base Aminos contains no stimulants or pre-workout compounds. If you are using it between meals as an amino acid maintenance strategy, it stacks with any NutraBio product without overlap concerns.†

How to Take NutraBio Base Aminos

Mix 1 scoop with 8-12oz of cold water. Consume before, during, or after exercise, or anytime throughout the day when hydration and recovery support is needed. Can be sipped gradually during training for sustained intra-workout amino delivery. Adjust water amount to preferred taste strength. No half-scoop tolerance assessment needed — no stimulants.†
