Libido Boost Plus Review
Libido Boost Plus is a male enhancement supplement designed to increase sex drive, give better control over climax, and improve sexual performance.
“Naturally boost your sex life!” reads one advertisement. “Libido Boost Plus is the perfect solution for giving you the best sex of your life.”
I looked closer at the ingredients to see if they are clinically proven.
What’s Under the Lid?
There are several ingredients in Libido Boost Plus. The company provides ingredient amounts, which is convenient for consumers.
Here is a closer look at some notable ingredients in the formula:
Vitamin B6 (20 mg)
This vitamin in coenzyme form participates in over 100 enzyme reactions.  Vitamin B6 also participates in neurotransmitter biosynthesis, and research shows it suppresses chlorpromazine-induced prolactin rise in some cases.  Significantly high prolactin levels decrease sex hormones. Consequently, this ingredient boosts libido.
Zinc (20 mg)
Zinc is associated with sperm quality and testosterone levels.
One study analyzed seminal zinc in fertile and infertile men. Research shows “poor ZN [zinc] nutrition may be an important risk factor for low quality of sperm and idiopathic male infertility.” 
Researchers measured serum testosterone in men before and after a marginal zinc deficiency. Zinc deficiencies resulted in a decrease in serum testosterone concentration. After zinc supplementation in marginally zinc-deficient subjects, serum testosterone increased from 8.3 +/- 6.3 to 16.0 +/- 4.4 nmol/L (p= 0.02). 
Yohimbine HCL (6 mg)
Yohimbine HCL was shown to increase subjective and objective criteria in patients with erectile dysfunction. Sexual parameters assessed included sexual desire and satisfaction, erection quality, and penile rigidity. Results indicate yohimbine “was found significantly more effective than placebo in terms of response rate.” 
Eurycoma Longifolia (100 mg)
This ingredient positively effects sperm volume, motility, and concentration. 
Arginine HCL (100 mg)
Arginine enhances blood flow by converting into nitric oxide. Nitric oxide relaxes vascular smooth muscle.  This allows for better blood circulation, which may result in more blood to the penis.
How Do You Use Libido Boost Plus?
Unlike other male enhancement supplements, Libido Boost Plus does not need to be taken daily. Instead, take 2 – 3 Libido Boost Plus capsules about 30 minutes before sexual activity.
Are There Any Side Effects to Worry About?
According to a Libido Boost Plus representative, there have not been any reported long term side effects. However, users may experience temporarily mild side effects like head and stomach ache due to sensitivity to an ingredient.
Users may decide to start with smaller doses to assess tolerance. If Libido Boos Plus is received favorably, increase the dose to the recommended amounts.
Where to Purchase Libido Boost Plus
Libido Boost Plus is available for around $20.00 per bottle. Depending on use, 1 Libido Boost Plus bottle lasts 1 month.
The best deals I found were on the official website LibidoBoostPlus.com, where the company offers free Invigorate HGH bottles, a natural HGH supporting supplement. Here is a look at what the official website has to offer:
