  • Making sure we get enough essential amino acids is important. This is because our bodies can’t produce them‚ so they need to be a steady part of our diets. Douglas Labs’ L-Tryptophan Vegetarian Capsules may be able to deliver the benefits of the amino acid known as Tryptophan.

    Douglas Labs’ L-Tryptophan Vegetarian Capsules provide 1000 mg of L-Tryptophan in each serving. This amino acid can be found naturally in both plant and animal proteins. It’s essential for the maintenance‚ development‚ and functioning of several vital organs.

    Upon absorption‚ L-Tryptophan undergoes conversion to 5-HTP (5-hyrdoxytryptophan)‚ and eventually serotonin. Serotonin is a neurotransmitter‚ which means that it is responsible for signal transmission between nerves. It can play a crucial role in mood regulation and bodily responses to stress.

    L-Tryptophan is also involved in the production of melatonin‚ which is responsible for the regulation of healthy sleep/wake cycles. Additional ingredients like Vitamins B2 and B6‚ niacinamide‚ and Vitamin C may also potentially support the production of serotonin as well.

    Help your body maintain proper levels of this essential amino acid. Order Douglas Labs’ L-Tryptophan Vegetarian Capsules from PureFormulas today!

    One of Best Forumlations of Tryptophan

    This is a good formulation of tryptophan. However you must be careful taking it because not everyone should if you are prone to certain conditions and studies have shown that the contaminant that caused serious illness before when the product was taken off the market because of manufacturing problems is still present. That having been said if you are low in tryptophan taking melatonin and 5 htp wont change that.

    I would recommend this item to a friend.
