Transparent Labs VitalityvsPrime Male Vitality

Vitality does not contain testosterone; instead it stacks plant extracts and minerals thought to support the body's own production. KSM-66 ashwagandha is an adaptogen that may lower cortisol and stress signaling, which can indirectly favor testosterone. Tongkat ali (Eurycoma longifolia, LJ100) is theorized to free up bound testosterone and support luteinizing hormone. PrimaVie shilajit and its fulvic acid have been associated with higher total and free testosterone in one trial. Zinc and boron are cofactors involved in testosterone metabolism, while DIM and quercetin are included to support estrogen metabolism, and BioPerine (black pepper extract) is added to improve absorption of the other ingredients. Note these are proposed mechanisms from individual-ingredient research, not effects demonstrated for the combined product.

Prime Male works through nutrient and botanical support rather than supplying testosterone. Vitamin D, zinc, magnesium, boron, and vitamin K2 participate in or support normal testosterone production, while D-aspartic acid and herbal extracts are included to nudge the hormonal signaling. As with the category generally, the rationale is correcting shortfalls, so the most plausible benefit is in men whose nutrient status is suboptimal.

Evidence is for the individual ingredients at these doses, not the finished blend (no published trial tests Vitality itself). In Pandit et al. 2016 (Andrologia), 250 mg of PrimaVie shilajit twice daily for 90 days raised total testosterone about 20%, free testosterone about 19%, and DHEA-S about 31% versus placebo in healthy men aged 45-55. A 2022 systematic review and meta-analysis in Medicina (Leisegang et al.) found Eurycoma longifolia significantly increased serum total testosterone across randomized trials (a large but statistically heterogeneous pooled effect), with benefits noted in both healthy and hypogonadal men. An ashwagandha trial in aging, overweight men aged 40-70 (Lopresti et al. 2019, American Journal of Men's Health, using a 21 mg/day withanolide-glycoside extract) found a 14.7% greater rise in salivary testosterone and an 18% greater rise in DHEA-S versus placebo, though it found no significant improvement in fatigue, vigor, or sexual well-being. Real-world results are modest and highly individual; some users report energy or libido benefits, others little change.

Evidence supports the building blocks more than the finished product: reviews link vitamin D deficiency to lower testosterone and show supplementation can modestly raise it, and zinc repletion raises testosterone in deficient men. There are no large independent trials proving the specific Prime Male blend meaningfully increases testosterone in already-replete men. Expect supportive, modest, deficiency-dependent effects rather than a clinical jump.

Most users tolerate Vitality well at the recommended dose. Common, usually mild effects can include digestive upset, drowsiness or sedation from ashwagandha, headache, and occasional GI discomfort from zinc or DIM (DIM can also harmlessly tint urine). More serious but rare concerns center on ashwagandha and tongkat ali: the NIH LiverTox database rates ashwagandha a probable cause of clinically apparent liver injury, with documented case reports of jaundice and cholestatic hepatitis (rare cases have required hospitalization or transplant), and ashwagandha may alter thyroid hormone levels (Denmark banned it in food supplements in 2020 over thyroid, sex-hormone, and reproductive concerns, though industry groups dispute that assessment). Tongkat ali has been associated with raised liver enzymes in some reports. Stop use and see a doctor if you develop jaundice, dark urine, abdominal pain, unusual fatigue, or a rapid heartbeat. As a dietary supplement, Vitality is not reviewed by the FDA for safety and efficacy the way prescription drugs are.

Generally well tolerated at label doses. Occasional mild digestive upset, headache, or sleep changes from the herbal components are possible. Anyone on medication or with a medical condition should consult a clinician first. This is educational information, not medical advice; statements are not FDA-evaluated.

As of 2026, a 60-capsule bottle (30 servings, roughly a one-month supply) runs about $46-$55 depending on retailer (about $46-$47 direct from Transparent Labs, around $54.99 at Amazon and Vitamin Shoppe), or roughly $1.55-$1.85 per serving. Subscribe and save typically takes about $6 off plus free shipping, dropping the direct price to around $41. As a dietary supplement it is not covered by insurance; FSA/HSA cards may apply at some retailers. Buying the generic single ingredients separately is cheaper but sacrifices the matched dosing and third-party testing. Prices vary by retailer and promotion, so confirm the current price at checkout.

As of 2026, one bottle (120 capsules, about a one-month supply at 4 capsules/day) runs roughly $75 on the official site with free US shipping, placing it at the higher end of OTC T-support products. Multi-bottle bundles lower the per-bottle cost. Available direct and via the brand's Amazon listing; not insurance-eligible.

Best suited for healthy adult men (often 30+) noticing fatigue, low drive, high stress, or sluggish recovery who want natural hormone support alongside diet, sleep, and resistance training. It is NOT for women, anyone under 18, or men seeking treatment for diagnosed hypogonadism (that requires a physician). Avoid or consult a doctor first if you have liver disease, thyroid disorders, are on thyroid, blood-pressure, sedative, or blood-sugar medication, have a hormone-sensitive condition, or are pregnant or breastfeeding. Ashwagandha has documented case reports of liver injury and may affect thyroid hormone levels, and tongkat ali has been linked to raised liver enzymes in some reports. As with any supplement, discuss it with your clinician before starting, especially if you take prescription drugs.

Healthy adult men, typically over 30-40, seeking OTC support for age-related testosterone decline, especially those who may be low in vitamin D, zinc, or magnesium. Not a treatment for diagnosed hypogonadism. Men on medications or with health conditions should consult a clinician before starting.
