Nugenix

Nugenix

“Feel like you did 20 years ago,” promises the Nugenix official website. But Nugenix is not an anti-aging miracle pill. It’s a testosterone booster. Needless to say, I was intrigued to know more about this promise. Can Nugenix really boost testosterone? Does it help men feel younger?

The only way to find answers was through research. My discoveries reveal the truth about Nugenix.

Who Makes Nugenix?

Direct Digital, LLC has been in business since July 2009, but they didn’t release Nugenix until September 2012. The company also makes Instaflex (active lifestyle) and Lumiday (mood enhancement).

The company appears to have a good reputation. I’m glad to see this because it means they probably make good products. Direct Digital does not have a Better Business Bureau listing, but the products have listings. The BBB gives Nugenix a B- rating. These factors increased the rating:

• Only 1 complaint was filed
• BBB found sufficient company background information

These factors lowered the rating:

• Length of time the business has been operating
• The company did not respond to 1 complaint

I was surprised to see such a low rating for Nugenix, when Instaflex has an A- rating. After all, they’re made by the same company. The reason Instaflex has an A- is because Direct Digital responded to 192 complaints that were filed.

What Ingredients Does Nugenix Use?

Each Nugenix bottle holds 90 capsules and 1 serving is 3 capsules. These are the ingredients and dosages found in each serving:

Zinc (5 mg). Research shows zinc not only increases testosterone, it also boosts sperm count.[1] Unfortunately, the zinc dosage in Nugenix is not large enough to produce similar results.

Vitamin B6 (2 mg). This vitamin stimulates androgen receptors, which signal the testes to produce more testosterone. I could not find research to support this theory. I also don’t know if Nugenix contains an effective dosage.

Vitamin B12 (50 mcg). It treats anemia, enhances memory, boosts mood, and increases energy. But vitamin B12 is not proven to elevate testosterone. Nugenix contains more than the recommended daily amount.

Testofen® Fenugreek Extract (undisclosed). 30 men consumed 500 mg fenugreek or a placebo. After 8 weeks, the fenugreek group lost body fat, and increased total and free testosterone. Researchers say fenugreek is also an aromatase inhibitor.[2]

L-Citrulline Malate (undisclosed). Scientists say citrulline may be better for improving blood flow than arginine. Citrulline is not metabolized as quickly, so the body has more to work with. One study showed citrulline improves blood flow and enhances erections.[3]

Tribulus Terrestris (undisclosed). Supposedly, tribulus increases luteinizing hormones, which signal the testes to make more testosterone. Several animal studies show tribulus increases testosterone, boosts libido, and enhances sexual performance.[4][5][6]

The last 3 ingredient dosages are undisclosed because Direct Digital uses a proprietary blend. The blend’s total dosage is 2,103 mg, but it’s impossible to tell how it is divvied up.

Is Nugenix Safe?

Nugenix contains safe zinc and vitamin B6 dosages. This is important since vitamin B6 is toxic in large dosages. Vitamin B12 is not toxic. So, even though Nugenix contains 850% DV, the toxicity risk is low.

My research shows Testofen®, L-citrulline malate, and tribulus terrestris are safe. However, I don’t know how safe Nugenix is because I cannot see all the dosages.

Nugenix Customer Reviews

The best places to find reviews are GNC.com and Amazon.com. Currently, there are 22 reviews on GNC.com; giving Nugenix an average 3/5 star rating. Amazon.com has 17 Nugenix reviews and a 2.6/5 star rating.

Most users were not impressed with Nugenix. They said it either didn’t make any difference or made their energy and libido worse. There are a few 4 and 5 star ratings on Amazon.com. But I’m skeptical about how unbiased the writers are. Their reviews are too positive and talk about life-changing results.

When I read other product reviews these “users” wrote, the enthusiastic wording was the same. It seems every product these people try is life changing; even flameless candles and art sets. One unsatisfied Nugenix user suggested the writers might be “guerilla marketers.” These are people who are paid to write positive reviews for companies.

On the plus side, not a single Nugenix review mentioned side effects or health issues.

Best Places to Buy Nugenix

If you decide to buy Nugenix, the best prices are on these secure sites:

• Nugenix.com: $69.99
• GNC.com: $69.99
• Amazon.com: $69.95

The official website doesn’t mention a return policy. GNC.com’s return policy lasts 30 days, but it only covers unused products. Return policies on Amazon.com vary by seller.

Is Nugenix Worth Buying?

Nugenix has 3 proven testosterone boosters: zinc, Testofen®, and tribulus terrestris. However, the zinc dosage is too small and Testofen® and tribulus dosages are not shown. If the company offered a guarantee, consumers could try Nugenix risk free. But this is not an option.

I’m very hesitant to recommend a testosterone booster with so many negative reviews. I suggest you buy a product with a better formula and more positive reviews. Nugenix is not the best choice.
