EAA Protein Support | Unflavoured - 210g

Unflavoured, and why that's the point

This is the same formula as our Lemon jar with the flavour system removed. No natural flavour, no monk fruit, no allulose, no sweetener of any kind. The only other ingredient is malic acid, which takes some of the edge off the bitterness without sweetening anything.

This matters if you're stacking. Flavoured powders might fight each other, for example a lemon amino blend in a berry smoothie or alongside a flavoured pre-workout produces something nobody wants to drink. Unflavoured mixes into whatever you're already having.

Set your expectations on taste. Free-form amino acids are bitter. That's chemistry, not a formulation flaw, and it's the honest trade for removing the sweeteners. Most people mix this into a smoothie, juice, or coconut water rather than plain water. If you want to drink it in water and enjoy it, buy the Flavoured EAA Protein Support instead with same actives, sweetened with monk fruit and allulose.

Why the label says 0g protein

Read the nutrition panel and you'll see Protein: 0.00g. That's accurate, and it's the single most misunderstood thing about EAA supplements.

Protein content on a nutrition panel is measured by nitrogen content and converted using a standard factor, a method built for intact protein chains. Free-form amino acids aren't chains. They're the individual units a protein would otherwise have to be broken down into, delivered pre-digested. The measurement method doesn't capture them, so the panel reads zero.

What you're actually getting per serving is 7,000mg of essential amino acids in a form your body can use immediately, without the digestion step. The panel number reflects the testing method, not the contents of the jar.

A note on how EAA protein equivalence works

Muscle protein synthesis runs in two phases. Initiation: leucine activates mTOR and signals the ribosome to start building. Elongation: the ribosome assembles the full chain, which requires all nine essential amino acids present in circulation simultaneously. If any one is missing, elongation stalls regardless of how much leucine triggered it.

This is why measuring an EAA formula in grams of protein alone misses the point. A complete EAA profile drives an MPS response disproportionate to its gram weight because there's no non-essential amino acid dilution. Whey protein is roughly 40–45% EAAs by composition. A complete EAA formula at the same essential amino acid content can drive a comparable stimulus at a fraction of the serving size. The question isn't how many grams. It's whether the profile can complete what leucine starts.

Five ingredients worth understanding specifically

L-Leucine — 2500mg · The mTOR trigger

Leucine is the primary activator of mTOR, the molecular switch that initiates muscle protein synthesis. At 2500mg it sits above the threshold consistently shown in research to activate this pathway meaningfully. Every EAA formula includes leucine. Not every formula includes it at a dose that does the job.

iCreatine® Creatine Monohydrate — 3000mg · ATP support

Creatine supports ATP regeneration during high-intensity output, strength and power output, and recovery between efforts. It is among the most thoroughly studied ingredients in sports nutrition. At 3000mg per serving this is a daily maintenance dose, not a loading protocol.

L-Citrulline — 1500mg · Nitric oxide pathway

Citrulline is converted to arginine in the kidneys, which the body uses to produce nitric oxide. Nitric oxide dilates blood vessels, supporting blood flow and oxygen delivery to muscle tissue during exercise, and the delivery of amino acids and creatine to working muscle. Citrulline is used here in place of arginine or AAKG because it survives first-pass metabolism and raises circulating arginine more effectively.

Taurine — 750mg · Cellular hydration and osmoregulation

Taurine is a conditionally essential amino acid involved in cellular hydration, osmoregulation and antioxidant defence. It is one of the most abundant free amino acids in skeletal muscle and is commonly included alongside creatine, which also draws water into muscle cells.

AstraGin® — 50mg · Absorption support

A branded extract of Astragalus membranaceus and Panax notoginseng, included at its standard 50mg dose. AstraGin® is used in formulas where the goal is to improve uptake of the actives alongside it.

Who this is built for

Athletes and active adults for performance and recovery

• Leucine at 2500mg meets the threshold for meaningful mTOR activation
• Creatine at 3000mg supports ATP regeneration, strength, power and sprint capacity
• Citrulline supports nitric oxide production for blood flow and oxygen delivery to working muscle
• Histidine, as a carnosine precursor, buffers lactic acid accumulation during high-intensity output
• Taurine supports cellular hydration alongside creatine

Anyone already running a stack

• No flavour or sweetener to clash with an existing pre-workout, protein or greens powder
• Mixes into smoothies, juice or coconut water without altering the taste profile

Vegetarians, vegans and low-protein diets

• Plant-based diets are consistently low in leucine, lysine and methionine — the three essentials most limiting in plant proteins
• Delivers the complete essential spectrum without dairy, soy or animal-derived protein
• B6 supports the metabolism of the amino acid load

Adults over 45 for muscle preservation and connective tissue

• Age-related muscle loss accelerates from the mid-40s and is linked to inadequate leucine and essential amino acid intake
• Lysine and glycine contribute to collagen synthesis and connective tissue structure
• Creatine is consistently shown to support muscle strength and function in older adults

What isn't in it

No sweeteners of any kind. No flavouring. No magnesium stearate. No silicon dioxide. No artificial colours. No sucralose. No acesulfame-K. No stevia. No soy. No dairy. No gluten. No maltodextrin.

All amino acids are fermentation-derived. GMP certified. Third-party lab tested.

How to use

Mix one and half scoop (14g) into 250–300ml of cold water, juice, coconut water or a smoothie. Stir and consume immediately. Best taken 20–30 minutes before training, or immediately after, or as directed by your healthcare practitioner.

On non-training days: any time of day, on an empty stomach or between meals. EAAs absorb rapidly without food and require no digestive load.

On creatine: at 3000mg per serving, creatine here is dosed for daily maintenance rather than a loading protocol. If you're using higher creatine doses under practitioner guidance, this contributes to your total daily intake.

Stacks well with: iThrive Magnesium Bisglycinate as magnesium supports muscle function and ATP production, with strong synergy with creatine. iThrive Active B-Complex for broader B-vitamin cofactor support for amino acid metabolism. iThrive Zinc Defense since zinc supports muscle protein metabolism.
