L-Carnitine Buying Guide

Shop L-carnitine supplements online, including pure L-carnitine powder, L-carnitine L-tartrate, capsules and liquid from Genetix Nutrition, Musashi, Healthwise and International Protein.

Last Updated: Friday 16th October 2026

What Is L-Carnitine?

L-carnitine is a compound the body makes from the amino acids lysine and methionine, and it is also found in foods such as red meat. As a supplement, L-carnitine is a popular caffeine-free option in sports nutrition, and it is one of the most common ingredients in stim-free fat burners.

At Nutrition Warehouse, you can buy L-carnitine supplements in Australia as unflavoured and flavoured powders, capsules and liquid. L-carnitine is not a substitute for a balanced diet and regular exercise, so most people use it as one part of a wider training and nutrition routine.

Types of L-Carnitine

You'll see a few different forms on supplement labels. Here's how they compare:

Form What It Is Example We Stock
L-carnitine The standard form, sold as a pure powder, capsules or liquid 100% Pure L-Carnitine by Genetix Nutrition Essentials
L-carnitine L-tartrate (LCLT) L-carnitine bound to tartaric acid, a common form in sports supplements L-Carnitine by Healthwise
Acetyl L-carnitine (ALCAR) L-carnitine with an acetyl group attached, sold as its own supplement Several brands, including Genetix Nutrition and Herbs of Gold
Carnitine blends Formulas that combine more than one form of carnitine Carni-Shot by International Protein

L-Carnitine Powder vs Capsules vs Liquid

  • L-carnitine powder: usually the lowest cost per serve. Unflavoured powder mixes into water or a shake, and flavoured versions can be mixed on their own.
  • L-carnitine capsules and pills: no measuring or mixing, which suits travel and work days. Try Carnitine Capsules by Musashi, listed below.
  • Liquid L-carnitine: a flavoured, ready-to-measure liquid, such as Carnigen Premium Liquid by Evogen.

How to Choose an L-Carnitine Supplement

  1. Pick your format: powder for value, capsules for convenience or liquid if you prefer a flavoured serve.
  2. Check the amount per serve: compare the milligrams of L-carnitine per serve, not just the size of the tub or bottle.
  3. Check the form: look for L-carnitine, L-carnitine L-tartrate, ALCAR or a blend on the label.
  4. Compare cost per serve: larger tubs, such as the 300g Genetix Nutrition Essentials powder, usually work out cheaper per serve.

How to Take L-Carnitine

Follow the serving size and directions on the product label. Because L-carnitine is caffeine-free, timing is flexible, and many people take it with a meal or before training. Not suitable for children or for pregnant or breastfeeding women. If you have a medical condition or take medication, speak to your healthcare professional first.
