Glossary

The words that come up on this site and in the studies, defined in plain English. Alphabetical.

Anserine

A close relative of carnosine found in bird and fish muscle. Often studied alongside it. Not in LactiGo.

Beta-alanine

An amino acid the body joins with histidine to make carnosine. Sold as a supplement powder; taken daily for weeks to raise muscle carnosine. Causes tingling in many people. See LactiGo vs beta-alanine.

Buffering

Soaking up acid so that pH changes less. Hard exercise makes muscle more acidic; carnosine is one of the molecules inside the muscle cell that buffers this.

Carnosinase

An enzyme in human blood that breaks carnosine into its two amino acids within minutes. The reason swallowed carnosine does not reach muscle well, and the reason beta-alanine is the usual oral route.

Carnosine

A dipeptide of beta-alanine and histidine, made and stored by the body, mostly in muscle and brain. The active ingredient in LactiGo.

Carnosine-magnesium complex

Carnosine bound to magnesium. The form in LactiGo, covered by its patent. A skin-model study found the complex passed through reconstructed skin better than free carnosine.

Cosmetic

A product applied to the body for cleansing, beautifying, or changing appearance or feel, regulated as a cosmetic rather than a medicine. LactiGo is sold as a cosmetic gel in Australia.

Crossover trial

A study in which each participant gets both the product and the placebo, in different sessions, so each person is their own comparison. The rugby sevens trial was a crossover.

Dipeptide

Two amino acids joined together. Carnosine is one.

Ethoxydiglycol

A cosmetic solvent and skin penetration enhancer, also called Transcutol. In LactiGo. See ingredients.

Go Packet

LactiGo's 10 mL single-use sachet. One application.

Informed Sport

A certification program in which every batch of a product is tested for banned substances by an accredited laboratory before release. LactiGo carries it. See drug testing.

ISO 17025

The international standard that accredits testing laboratories. Informed Sport testing is done under it.

Meta-analysis

A study that pools the results of many trials to estimate an overall effect. The 2017 beta-alanine meta-analysis pooled 40 studies.

Null result

A trial outcome where the product and the placebo did not differ by a meaningful amount.

Paraesthesia

The tingling, prickling skin sensation beta-alanine causes. Harmless, disliked.

Peak power

The highest power output in a sprint, measured in watts. The main outcome in the rugby sevens trial.

Placebo

An inactive look-alike given so that participants and researchers cannot tell who got the real thing. A trial without one cannot separate the product from expectation.

Repeated sprint

A test protocol of short all-out efforts with short rests, used to mimic team sport. The rugby sevens trial used 12 six-second sprints.

Stockist

A business that sells or supplies a product. On this site it means an independent affiliate who holds some stock for trials and links buyers to LactiGo's store.

Subscribe and Save

LactiGo's monthly subscription. 10% off, managed in the customer portal, no minimum term.

Topical

Applied to the skin.

Transdermal

Passing through the skin into the tissue beneath. The claim at the heart of LactiGo, measured so far in a skin model and in horses.

Triple-blind

A trial in which participants, the people running the sessions, and the people analysing the data all do not know who got the product. The strongest form of blinding.

WADA

The World Anti-Doping Agency. Publishes the Prohibited List. Carnosine is not on it.

Wingate test

A 30-second all-out cycling sprint against a fixed resistance. A standard laboratory measure of anaerobic power.

Yo-Yo test

A shuttle-run fitness test used in football. The 2016 footballer report used it.
