Force Fit XL Review
The nine active Force fit XL ingredients in the Force Fit XL testosterone booster

Many of the Force Fit XL ingredients included in the FlowViv proprietary blend have roots in traditional medicine and have been used to improve male health for hundreds of years.

Force Fit XL Ingredients

Force Fit XL uses an 8-ingredient proprietary blend of herbs and one amino acid, with an addition of calcium. Dubbed the FlowViv MAX-TEST Blend, Force Fit XL incorporates eastern and western medical ideals into their mix. The proprietary blend lists a combined dosage of 1484mg, with no indication of the individual measurements per ingredient. Here is a closer look at each ingredient in the Force Fit XL blend, and how it works to potentially support an enhanced physical performance.

Calcium: 44.28 mg – Calcium is a chemical element and mineral which has been linked to good bone health. Calcium has shown promise as a preventative measure against the breaking down of bone cells and tissue during endurance exercise training.2

Horny Goat Weed (leaf)Epimedium Grandiflorum, also called horny goat weed, is an herbal extract used in traditional Chinese medicine to treat testosterone and libido issues. Animal studies provide positive feedback on the neurotrophic (nerve tissue growth) effect of horny goat weed on penile tissues.3

Tongkat Ali has been shown to increase ATP (energy) production by up to 60%.6

Tonkat Ali Extract (root): 100:1 – Tonkat Ali (Eurycoma longifolia), also known as Malaysian Ginseng, is a South East Asian herb which has been traditionally used to increase libido and testosterone levels in males. Most studies involving tonkat ali are animal based, but in 2011 a human study showed a significant increase in testosterone and the improvement of aging male symptoms associated with late-onset hypogonadism.4

Saw Palmetto Extract (fruit) – Saw palmetto (Serenoa repens), is a palm tree which produces fruit used for medicinal purposes. One 2012 review reported saw palmetto to be successful at treating prostatic hyperplasia (enlarged prostate), nocturia (excessive night time urination), as well as a modest improvement in sexual performance.5

Orchic Substance – Orchic substance is extracted from the testicles of animals like bulls and boars, and has been traditionally used in Asian cultures to improve sperm, testosterone levels, and increase sexual virility.

Wild Yam Extract (root) – The wild yam (Dioscorea villosa) contains plant steroids, which are claimed to provide a natural testosterone boost. Although wild yam is used in supplements as a testosterone enhancing agent, there is ongoing research on the body’s ability to convert plant steroids into steroids found in the body.7

Sarsaparilla (root) – Sarsaparilla root (Smilax ornate) is used by body builders and athletes as a performance enhancer. In 2015, a study with human subjects found that a proprietary blend of ingredients, including sarsaparilla, successfully increased testosterone, libido and body weight as well as decreased body fat.8

Nettle Extract (root) – Nettle root (Urtica urins), also known as stinging nettle, offers Force Fit XL both antinociceptive (pain blocking), and anti-inflammatory properties. These properties were proven to be benefits of the root in a 2010 study.9

Boron (chelate) – Boron, a chemical element found in foods like bananas, walnuts, and chickpeas, is another natural anti-inflammatory. This trace mineral also influences the body’s use of hormones and improves wound healing.10

How to Use Force Fit XL

According to the Force Fit XL directions, users should take 2 capsules orally 1-2 times per day.

Force Fit XL Side Effects

Force Fit XL describes its product as safe and effective for all users. While the supplement has no adverse effects or Force Fit XL safety concerns listed online, there may be some minor side effects of Force Fit XL due to sensitivities to individual ingredients.

Information on the side effects of horny goat weed is mostly anecdotal, with Traditional Chinese medicine (TCM) practitioners suggesting that it could cause aggressiveness, irritability, and flushing if not taken with yin tonic herbs. Animal studies have shown horny goat weed to cause thyroid problems when used in excess.11 Saw Palmetto rarely causes side effects, but in those with sensitivities it may cause dizziness, headaches, diarrhea, and nausea.12 When used in moderation nettle is considered safe, however, it can cause sweating, bloating, rash, and mild stomach upset.13 Sarsaparilla may cause temporary stomach upset and in rare cases, kidney issues.14

Does Force Fit XL Work?

The Force Fit XL testosterone booster formula contains a variety of scientifically-researched ingredients. However, due to the lack of information on the dosing of individual ingredients in the FlowViv MAX-TEST Blend, we cannot confirm whether the doses of each ingredient could significantly change athletic or sexual performance.

In healthy males, supplementing with 6 mg of boron for only one week has been clinically shown to boost free testosterone levels.10 While the dose of boron in the Force Fit XL formula is unknown, its possible it contains a similar effective dose. Boron and nettle extract also contain natural anti-inflammatory properties which may help reduce muscle soreness after bouts of physical exercise.

In a 2011 study, 200mg of tongkat ali was given to men who demonstrated signs of late on-onset hypogonadism. After one month, tongkat ali successfully boosted testosterone levels to normal levels and helped patients manage the symptoms of the condition.4 For men with undiagnosed low testosterone, supplementing with herbal extracts may improve symptoms.
