Lamberts L-Glutamine 500g Powder is a food supplement made of pure L-glutamine, an amino acid, in a 500g pot of white powder. Lamberts describes it as mild tasting, and it can be mixed into drinks or sprinkled on food, so a 5g serving does not need to be swallowed as capsules.

Key Features

• 5g per heaped teaspoon: Lamberts gives 1 heaped teaspoon as 5g, and each 5g serving provides 5g of L-glutamine and 20kcal.
• Equal to up to 10 capsules: Lamberts notes that the usual 5g dose would fill 10 capsules.
• Flexible daily intake: The directions cover 5g a day, or 5 to 10g a day for use around exercise.
• Mixes into drinks or food: Lamberts says the powder can be mixed into drinks or sprinkled on food.
• Suitable for vegetarians and vegans: The powder is marked suitable for both.

How many servings are in a 500g pot?

A 500g pot holds 100 servings of 5g. At the maximum intake of 10g a day, it lasts 50 days.

Should I choose the powder or the 500mg capsules?

Lamberts also sells L-Glutamine 500mg capsules, which give 500mg per capsule at 1 to 6 capsules a day. Lamberts says its powder suits higher daily amounts, because the usual 5g dose would need 10 capsules.

What is glutamine?

Lamberts describes glutamine as the most abundant naturally occurring non-essential amino acid in the body. It can be found in protein-rich foods such as red meat, nuts and fish.

Active ingredient: L-Glutamine, 5g per 5g serving (100g per 100g). Energy: 20kcal per 5g (400kcal per 100g).

Additional information: A white powder. Suitable for vegetarians and vegans. The manufacturer states these allergens are excluded: wheat, barley, soya, eggs, milk (and milk products), lactose, nuts, sulphites, celery, fish, shellfish, yeast and gluten-containing ingredients.

1 heaped teaspoon = 5g. Lamberts gives two sets of directions:

• 5g a day: Mix 5g into water or fruit juice, at least half an hour away from food or at bedtime.
• 5 to 10g a day: Mix 5g into a drink such as fruit juice, squash or water just before exercise. A further 5g can be taken before bedtime.
