Ultra Alpha Ingredients

Ultra Alpha contains the following core ingredients:

  • Oat straw extract (aerial parts) (10:1) 200 mg;
  • Longjack root extract (100:1) 100 mg;
  • Ashwagandha root extract 50 mg;
  • Mucuna seed extract (40% L-Dopa) 100 mg;
  • Diindolylmethane 100 mg.

The formula also contains the following support ingredients: Tribulus Terrestris fruit extract (45% saponins) 50 mg, Nettle leaf extract (4:1) 50 mg, Magnesium (as magnesium oxide) 20 mg, Zinc (as zinc oxide) 15 mg, and Black pepper fruit extract (Bioperine) 5 mg.

Inactive ingredients: hypromellose, rice flour, and magnesium stearate.

Oat straw extract – Oat straw comes from green oats, also known as Avena sativa, a plant that has been used to support brain health since the Middle Ages. Its proponents say it can increase energy, reduce the risk of heart disease, improve physical and possibly even sexual performance, and reduce anxiety.

Longjack root extract – Tongkat Ali’s ability to increase testosterone levels in men with low levels of this primary sex hormone is well documented and well known. Low testosterone can result from chemotherapy, aging, radiation treatments, injury or infection of the testicles, some medications, and certain diseases, such as chronic alcoholism and obstructive sleep apnea.

Effects of inadequate testosterone levels include erectile dysfunction, low libido, and in some cases, infertility. Since compounds in Tongkat Ali may boost low testosterone, it could treat these issues.

A 1-month study in 76 older men with low testosterone found that taking 200 mg of Tongkat Ali extract per day significantly increased this hormone’s levels to typical values in over 90% of participants.

Ashwagandha root extract – Ashwagandha is also used as an “adaptogen” to help the body cope with daily stress and general tonic. Some people also use ashwagandha to decrease pain and swelling (inflammation), improve thinking ability, and prevent aging. It is also used to increase sexual desire and for fertility problems in men and women.

Ashwagandha is used for anxiety, bipolar disorder, arthritis, balance, obsessive-compulsive disorder (OCD), attention deficit hyperactivity disorder (ADHD), tumors, tuberculosis, asthma, trouble sleeping (insomnia), a skin condition marked by white patchiness (leukoderma), fibromyalgia, menstrual problems, hiccups, bronchitis, backache, Parkinson’s disease, and chronic liver disease.

It is also used to reduce the side effects of medications used to treat schizophrenia and cancer. Ashwagandha is used to reduce levels of fat and sugar in the blood.

How To Take Ultra Alpha?

The recommended daily dose is two capsules. Because of the low daily dose, the effects may only last for a few hours. Natural testosterone boosting is a long process. Your testosterone levels need to be continuously supplied with the nutrients they need to stay on the rise throughout the day. A top-up once every 24 hours isn’t going to cut. Ideally, you want something that delivers three or four servings a day.

How Much Does Ultra Alpha Cost?

Price is one of Ultra Alpha’s strong selling points. One bottle (60 capsules) costs $14.95 and should be enough for a full month of use. Some online retailers may offer additional discounts or free shipping for orders from within the United States.

Some of the online stores selling Ultra Alpha include: 

Side Effects & Warnings

According to ForestLeaf, this formula is made with 100% natural ingredients, making it safer than other testosterone boosters. However, some users have reported rare occurrences of mild side effects such as nausea, nervousness, and sleeplessness.

Ultra Alpha product warnings are similar to what you should expect from a testosterone booster:

  • Do not exceed recommended serving;
  • It is not intended for pregnant or nursing mothers, children under the age of 18, or individuals taking prescription drugs;

Ultra Alpha looks like a decent testosterone booster. The formula contains 100% natural ingredients, and the product has received quite a few positive reviews from real customers.
