Oat Straw is one of the 11 nootropic ingredients found in the Alpha Brain supplement from Onnit Labls.
Oat Straw refers to the green oat grass tops that are found in the ‘milky’ stage before the mature oat grains form a head. The technical name for the plant is avena sativa and it is the same plant from which oatmeal and plain oats are derived.
Oat Straw Extract has a number of cognitive enhancement effects and is consider a natural anti-stress nutrient. It has been found to increase attention span, improve mental performance in impaired individuals, relieve neurological pain, and reduce anxiety.
This substance is also exceedingly rich in nutrients including calcium and is thought to have a number of healing properties, especially in the areas of reproductive health and osteoporosis.
Also known as wild oats and groats, these grasses are native to the country of Scotland. It has been used for hundreds of years in medicinal applications and is frequently consumed as a tea.
As a nutritional supplement, Oat Straw is normally used as an extract and may be sold on its own or combined with other herbs in products such as Alpha Brain.

Oat Straw has been show to increase or trigger the release of a specific type of lueteinizing hormone.
This hormone is thought to lead to an overall hormone surge which is capable of stimulating cell growth. This cell growth helps to build bone strength and helps with osteoporosis.
Of course, since many different types of cells are stimulated, this supplement is thought to have a number of additional and widespread beneficial effects.
One of the methods in which this supplement works is by acting as a diuretic. This means that it helps to remove water and fluid from the body. As a powerful herbal diuretic, Oat Straw works by increasing the urine flow. It forces the kidneys to essentially put more sodium into your urine.
This, in turn, will ‘soak up’ more water along with the excess urine. This ultimately means that you will have less fluid running through the veins and less pressure being placed upon the artery walls. This action can also be helpful in treating things like water retention, urinary tract infections, and kidney stones.
Oat Straw Benefits:
One of the most interesting benefits supplied by Oat Straw is the fact that it delivers organic calcium to the body. Many other forms of calcium supplementation actually use an inorganic material which cannot be assimilated by the body. This can lead to the formation of deposits in weakened or injured areas.
But since Oat Straw is organic, it is able to help strengthen the bones. Of course, this is also part of the effects of the leuteinizing hormone release, helping to increase bone strength through cellular stimulation and growth.
Oat Straw is also considered to be a beneficial nervine herb. In other words, it helps to calm, soothe, and nourish the nervous system. It’s ability to reduce anxiety and stress levels has been confirmed by many current users. The supplement also contains a powerful vitamin B complex to boost sustained energy. At night-time, it also encourages restful sleep and an overall sense of well-being.
Additional Oat Straw Effects
Oat Straw may even help to enhance brain power. A recent study confirmed that the supplement significantly improved the concentration, focus, and attention abilities of elderly adults. There was also another study that shows Oat Straw extract has a positive impact on cognitive performance in healthy people as well as those who might be suffering from some type of decline.
Oat Straw is also commonly reported to improve male sexual performance. A number of libido-enhancing formulations already use this supplement as a key ingredient and there is a lot of anecdotal evidence to support these claims. When used in combination with saw palmetto and/or stinging nettle, this supplement is thought to be a very effective arousal aid for women.
Oat Straw Dosage:
The dosage of this supplement will depend upon what form or purpose it is used for.
As a tea, users may take up to 3 cups a day as a recommended dose.
If you are using an alcohol tincture formulation, than the typical dosage seems to be ½ to 1 teaspoon up to three times per day.
For pills or capsules, or even powdered formulations, there really is no suggested recommended dosing levels. However, many experts seem to recommend taking in the area of between 1 and 4 grams per day.
In the Onnit Alpha Brain formulation, there is 100 mg of Oat Straw (20:1) per serving or in every two capsules. While this is a lower amount that what you would use if you were taking Oat Straw on its own, when stacking with other supplements it is recommended to lower the dosage.
Oat Straw Side Effects:
While this supplement is generally considered to be safe and well-tolerated, especially for healthy adults, those with gluten sensitivity should be very careful when taking Oat Straw. Other than some minor allergic reactions, there are no known side effects or any type of contraindications.
Oat Straw Review:
