Libido, energy & blood flow

Men’s Sexual Health

Top 10 vitamins and minerals that may support men’s libido. Evidence is strongest for correcting deficiencies that affect testosterone, energy, or blood flow.

1

Zinc

Supports testosterone production and sperm health. Deficiency is linked to lower testosterone and reduced libido; correcting it can help restore levels.

Zinc50 mg · 120 capsules$3.49
2

Vitamin D3

Acts more like a hormone. Low levels are associated with lower testosterone and higher rates of erectile dysfunction. Supplementation helps most in deficient men.

Vitamin D310,000 IU · 120 softgels$7.99
Vitamin D3 + K25,000 IU / 100 mcg · 60 capsules$11.99
3

Magnesium

Involved in testosterone production and free testosterone availability. Also supports sleep, muscle function, and relaxation, which can indirectly help libido.

Magnesium Glycinate500 mg · 120 capsules$8.99
4

Vitamin B6

Helps regulate hormones and neurotransmitters related to mood and desire. Part of the evidence for B vitamins supporting sexual function when levels are low.

Vitamin B6100 mg · 120 capsules$5.99
5

B-Complex

Supports energy metabolism and reduces fatigue that can lower libido. B12 and other B vitamins are commonly included in men’s formulas for this reason.

B-ComplexB-100 · 90 capsules$7.99
Vitamin B125,000 mcg · 90 capsules$8.99
6

Vitamin C

Antioxidant that supports blood vessel health and nitric oxide pathways involved in erections. Also helps overall recovery and immune function.

Vitamin C1,000 mg · 120 tablets$6.99
7

Folate (Methylfolate)

Involved in nitric oxide production and blood flow. Some research links adequate folate to better sexual function markers.

Folate (Methylfolate)15,000 mcg · 90 capsules$9.99
8

Selenium

Supports sperm production and antioxidant defense. Has an authorized health claim in some regions related to normal fertility/spermatogenesis.

Selenium200 mcg · 90 capsules$5.99
9

Vitamin E

Antioxidant that protects cells involved in hormone production and blood vessel health. Often included in men’s reproductive support formulas.

Vitamin E400 IU · 90 softgels$6.99
10

Vitamin K2 (with D3)

Supports proper calcium use and vascular health. Often paired with vitamin D in formulas targeting overall men’s hormone and circulation support.

Vitamin D3 + K25,000 IU / 100 mcg · 60 capsules$11.99

HPLC Purity Analysis

High-Performance Liquid Chromatography confirms molecular identity and verifies purity levels exceed 99% on every production batch.

Mass Spectrometry

Independent mass-spec screening detects trace impurities at the molecular level, ensuring structural integrity you can cite with confidence.

Verified Compounds

Every compound is HPLC and mass-spec verified with a batch-specific certificate of analysis — quality you can document and cite with confidence.

Certificates of Analysis, on demand

Batch-specific COAs with full HPLC and mass-spec documentation for every compound — tested by Purity Spectrum Analytics and verifiable on their site.
