Iron Labs T19 Xtreme Overview

What You Need To Know About Iron Labs T19 Xtreme

Iron Labs T19 Xtreme is designed to increase your testosterone levels. With increased testosterone production, you are likely to feel more energetic when working out in the gym. You will be able to handle your workout sessions better, which in turn will improve muscle gain.

This supplement, which is designed to be used by men over 40, contains herbs, amino acids, and vitamins and minerals.

T19 Xtreme is manufactured by Iron Labs Nutrition, a sports supplement company, based in the UK. They were established in 2009, but then in 2013, the company became part of the Euro Nutrition Group and rebranded.

What Are The Side Effects Of Iron Labs T19 Xtreme?

Testosterone boosters always come with a risk of side effects, as raising testosterone levels too much can cause mood swings, increased body hair, and a heightened sex drive.

Some of the individual ingredients found in this product may also cause side effects on occasion. Fenugreek may lower blood sugar levels and cause stomach issues, chest problems, nasal congestion, a sweet odour in the urine, and other issues.

Other miscellaneous side effects include headaches, flushing, swelling, dizziness, dehydration, increased body temperature, restlessness, and irritability.

How Much Does Iron Labs T19 Xtreme Cost?

Iron Labs T19 Xtreme costs £24.99 from Amazon, and one bottle will last for 40 days.

Our Verdict On Iron Labs T19 Xtreme

There is some evidence that D-Aspartic Acid (DAA) may increase endogenous production of growth hormones like testosterone. The effects are usually quite small, and may even vanish after some time, as your body gets used to the increased DAA intake. It is important to bear in mind that a prolonged use of T19 Xtreme may also lead to several side effects.

Fenugreek and zinc do not have enough scientific evidence to support their use as testosterone boosters. It may not work at all for most people, but even when it does, you will be at an increased risk of dealing with hormonal imbalance.

The vast majority of the ingredients, including the main ones, are highly underdosed, so even if the ingredients were likely to have any benefits then this product would be unlikely to do anything. Panax ginseng, fenugreek, curcumin, and 5-HTP are all present here at extremely low doses.

Due to all of this, we cannot possibly approve this supplement. We do not recommend Iron Labs T19 Xtreme to our readers.

Iron Labs T19 Xtreme Key Features

Iron Labs T19 Xtreme provides you with D-aspartic acid, an amino acid found naturally in testes, in the hypothalamus, and in the pituitary glands. Supplement manufacturers claim that supplementing with DAA can increase levels in the body, which in turn stimulates the pituitary gland to produce free testosterone. Increased testosterone levels are associated with better sports performance, improved stamina, and better sexual health. The problem is that studies do not back all the claims associated with DAA supplementation.

Many animal studies have shown some promising results, but it is hard to replicate the same findings in human studies. Studies in humans have actually shown contradictory results. It appears that DAA may work differently for different people. These studies also show that DAA is only likely to work when you already have a low testosterone level. It means that if you are currently training and have normal testosterone levels, you are not going to see any change in your T-levels after DAA supplementation.

Iron Labs T19 Xtreme Facts

  • Contains 120 capsules per bottle
  • Manufactured by Iron Labs Nutrition
  • Testosterone supplement

As well as this, even if DAA does something to increase testosterone, the effects are not going to last long. DAA enacts a reverse feedback mechanism as testosterone levels in the body begin to increase above a physiological range; the body naturally decreases the production of LH since more testosterone is not needed.

How to Take Iron Labs T19 Xtreme

The directions on Amazon say to take 4 capsules daily, however the bottle says differently so you should follow those directions instead:

  • Take 3 capsules upon waking with a small glass of water. Take a 2 week break after 8 weeks of continuous use.

T19 Xtreme also contains B vitamins, but they are not going to make it any better. Most people who are on a balanced diet do not usually need to supplement with B vitamins.

It is thought that regular intake of fenugreek extract may boost testosterone levels, but again, there is insufficient scientific evidence to confirm the claims. Some studies have failed to notice any effect. Also, you only get 45mg of fenugreek extract in each serving of T19 Xtreme, which is equivalent to 180mg of fenugreek, whereas some studies show that even 500mg may fail to produce significant results.

There is some evidence suggesting that zinc may help boost testosterone levels to some extent, but that is only when you are already severely deficient in zinc. Keep in mind that taking zinc when you are not already deficient in it could lead to copper deficiency, which can cause serious complications.

Iron Labs T19 Xtreme Concerns:

  • Not effective for most people
  • Lack of scientific evidence
  • Possible side effects

T19 Xtreme is manufactured by Iron Labs Nutrition, a British supplement supplier that has been operating since 2009. The company can be contacted via the details supplied on their official website.

What Does Iron Labs T19 Xtreme Claim To Do?

Iron Labs T19 Xtreme doesn’t make many claims at all. They say it contributes to normal testosterone levels in the blood, and provides benefits in and out of the gym.

Does Iron Labs T19 Xtreme Work?

There is insufficient scientific data to support the use of DAA as a testosterone booster. Preliminary research has produced encouraging results, but more research is required to see if DAA can really lead to a significant increase in testosterone levels.

Available studies have found that even if there is an increase in testosterone, the effects do not last for long. It means you will stop noticing any results after some time. Moreover, you may experience several side effects when using Iron Labs T19 Xtreme. Therefore, it is better to pay attention to your diet, exercise, and get plenty of sleep to raise your T-levels naturally.

Fenugreek and zinc are also supposed to work as testosterone boosters, but there is insufficient scientific evidence to support those claims. Most of the ingredients in this product are also very low, so it is unlikely to do much at all.

What Are The Ingredients of Iron Labs T19 Xtreme?

The ingredients used in Iron Labs T19 Xtreme are listed below. The ingredient quantities listed are correct for 3 capsules:

  • D-Aspartic Acid 1,500mg: This amino acid that has been proven to raise testosterone and Luteinizing Hormone (LH) levels in men who have low testosterone levels. LH is used by the body to produce more testosterone. This form of DAA appears to have a low bioavailability, and could cause a stomach ache. Source
  • Maca Extract (Equivalent to 1,350 Maca) 135mg: This Peruvian plant has been used for numerous ailments, including infertility, and to boost the sex drive. No clinical evidence has been presented to support any use. Source
  • Magnesium 60mg: Magnesium is required for a range of bodily processes, including energy production, protein synthesis, blood pressure regulation, and more. Source
  • Fenugreek Extract (Equivalent to 180mg Fenugreek) 45mg: Research indicates that fenugreek causes a noticeable boost to libido, but its supplementation does not seem to affect testosterone levels. It can also be used to treat a loss of appetite. Source
  • Panax Ginseng Extract (Equivalent to 180mg Panax Ginseng) (Providing 20% Ginsenosides) 45mg: Associated with improved cognition in fatigued subjects and slight decreases in muscle damage after exercise. It also appears to reduce fatigue, and consumers report feeling calmer after consumption. Source
  • Curcumin Extract 45mg: The active ingredient of turmeric. While well-known for its anti-inflammatory properties, it is not easily absorbed. This is overcome by pairing curcumin with an absorption-enhancer such as black pepper. Source
  • Zinc 22.5mg: Supposed to boost testosterone levels, but it usually works only when you are severely deficient in zinc. Too much of this mineral can actually cause serious side effects.
  • Niacin (B3) 15mg: Responsible for helping to produce energy from consumed food, as well as helping keep the nervous and digestive systems healthy. Niacin can be easily sourced in adequate amounts from a balanced diet. Persistent excessive consumption of niacin has been linked with increased rates of obesity in American Children. Source
  • Vitamin B6 4.5mg: Has several important functions in the body, including allowing the body to use and store energy from protein and carbohydrates in food. Source
  • 5-HTP 1.5mg: Used by the body to make serotonin, which primarily plays a role in regulating mood. Some studies, primarily in animals, have shown that 5-HTP reduces the appetite, as well as boosting mood. Human studies looking at 5-HTP and appetite note that appetite suppression is only seen at higher doses. The recommended daily dose is typically in the range of 300-500mg, with lower doses having reduced effects. Source
  • Biotin 60mcg: A vitamin that is an important component of enzymes in the body that break down certain substances like fats, carbohydrates, and others. It is found in small amounts in many foods. Source
  • Vitamin B12 7.5mcg: Naturally present in many foods. It has several roles, including aiding in releasing energy from consumed food and keeping the nervous system healthy. It may be that a deficiency hinders weight loss, but taking excess amounts could be potentially harmful. Source
  • Vitamin D3 (300iu) 7.5mcg: Helps to regulate the way that the body uses key minerals, helping to keep bones and teeth healthy. An association has been found between having high levels of Vitamin D in the blood and having better memory function, although taking Vitamin D supplements is not thought to directly improve memory. Source
  • Other ingredients: Capsule Shell: Hydroxypropyl Methylcellulose, Bulking Agent: Dicalcium Phosphate, Anti-Caking Agents: Magnesium Stearate, Silicon Dioxide.
