Pure L-Glutamine PowderDoctor's Best Pure L-Glutamine Powder, 300 g (10.6 oz)

An unblended amino acid powder

Doctor's Best sells this as a single-ingredient L-glutamine powder, and the label lists no other ingredients. It is described as non-GMO, gluten free, soy free and vegan, and it comes with a scoop for measuring.

Mixing and timing

The directions are to add one level scoop to 8 oz (240 ml) of juice or a protein shake and mix well, with the maker suggesting a serving about an hour before exercise and another after exercise or before bedtime. Because the powder settles over time, the container may look less full than when it was packed.

How to use

Adults add 1 level scoop to 8 oz (240 ml) of juice or a protein shake and mix well. For best results, drink 1 hour before exercise, and repeat after exercise or before bedtime, or as recommended by a nutritionally informed physician.

Before you choose

Avoid this product if you are pregnant, lactating or have liver problems. If you are sensitive to monosodium glutamate (MSG), you may be sensitive to glutamine, as the body converts glutamine to glutamate. The maker recommends supplementing with B vitamins if taking L-glutamine long term. The density of the powder varies from lot to lot, and it settles over time. Store in a cool, dry place. Food supplement. Do not exceed the recommended daily intake. Not a substitute for a varied diet. Keep out of reach of children. Consult a doctor before use if pregnant, breastfeeding, taking medication or under medical supervision. US-market product: packaging and label wording may differ from UK versions.
