Curated, not stocked.
Thorne is one of a small number of supplement brands our clinical team trusts consistently. Their amino acid formulations are straightforward and avoid the unnecessary fillers and proprietary blends that make many competitor products hard to evaluate. We recommend Amino Complex specifically for patients in active training, those managing muscle maintenance with age, or anyone whose intake of complete dietary protein is regularly falling short.
About this product
Amino Complex
Thorne Amino Complex is an essential amino acid (EAA) supplement in powder form, designed to support muscle protein synthesis and recovery. Unlike branched-chain amino acid (BCAA) products, which provide only three amino acids, a complete EAA profile supplies all nine amino acids the body cannot manufacture on its own — the full set required to build and repair muscle tissue. This makes it a more complete option for anyone whose dietary protein intake may be insufficient or whose recovery demands are high.
It suits athletes in structured training blocks, those returning from injury, older adults managing age-related muscle loss, and anyone who struggles to meet daily protein targets through food alone. It is particularly relevant where a blood test or dietary review has flagged suboptimal protein status.
As a powder, it can be taken around training or at any point in the day where a light, rapidly absorbed amino acid source is useful — without the caloric load of a full protein shake. Thorne is a brand with a longstanding reputation in the clinical and sports performance space, and is a common recommendation among practitioners who prioritise manufacturing rigour and ingredient transparency. The formulation is straightforward: it delivers what the label says without unnecessary additives obscuring the active content.

How to use
Mix one scoop with water or a cold beverage daily. Taking it around your training session — before, during, or after — is a common approach, though it can be used at any time of day. Follow the dosage guidance on the packaging for best results.

Common questions
Frequently asked
How is this different from a BCAA supplement?
BCAAs contain only three amino acids — leucine, isoleucine, and valine. Essential amino acids (EAAs), as found in this product, include all nine amino acids the body cannot synthesise itself. For muscle protein synthesis to occur, all nine are required, so a complete EAA profile is generally considered the more effective choice.
Can I use this alongside a protein powder?
Yes. EAAs and protein powders serve overlapping but distinct roles. If your protein powder already provides a complete amino acid profile (as most whey and many plant blends do), additional EAAs are not strictly necessary — but some people use EAAs intra-workout when a full shake isn't practical.
Who is this particularly well suited to?
It is especially relevant for athletes in heavy training, older adults looking to maintain muscle mass, those recovering from injury, and anyone whose diet is consistently low in complete protein sources. A dietary review or blood test can help confirm whether amino acid supplementation is appropriate for you.
Is this suitable for vegetarians or vegans?
Check the packaging for full ingredient and allergen details, as formulation specifics can change. The product label will confirm whether it is free from animal-derived ingredients.
How long before I notice a difference?
Amino acid supplements work acutely — they are available to muscle tissue relatively quickly after ingestion — but meaningful changes in muscle mass or recovery quality typically become apparent over several weeks of consistent use alongside appropriate training and overall protein intake.
