Boostaro at a glance
What Boostaro is built to support
Boostaro is a two-capsule daily supplement positioned for men seeking nutritional support for circulation, nitric-oxide pathways, stamina and everyday vitality. The current seller page lists L-Citrulline, maritime pine bark extract, Vitamin C, L-Lysine, magnesium, Vitamin K2 and nattokinase; our evidence section separates those ingredient-level findings from claims about the finished product.
How the formula is intended to work
Current merchant page self-identifies as the official store and lists individually disclosed ingredient amounts, but those amounts conflict with the supplied migration snapshot, which showed Vitamin C 500 mg, Vitamin K 100 mcg and a 725 mg proprietary blend. Exact current label remains unresolved.
Boostaro ingredients & declared dosages
| Ingredient | Declared amount | Manufacturer / label context | Evidence / potential role |
|---|---|---|---|
| L-Citrulline | 500 mg claimed on current merchant page; conflicting snapshot exists | Merchant says 2 capsules daily | A small human trial used 1.5 g/day L-citrulline for mild erectile dysfunction; that ingredient-level study does not establish Boostaro efficacy. [citrulline] |
| Maritime Pine Bark Extract | 100 mg claimed on current merchant page | Exact current label not independently confirmed | Ingredient research cannot be assumed to prove outcomes for the finished formula. [fda-supplements] |
| Vitamin C | 100 mg claimed on current merchant page; migration snapshot listed 500 mg | Conflicting label information | Vitamin C is required for collagen biosynthesis and has antioxidant functions; this does not prove a circulation or sexual-performance outcome. [vitamin-c] |
| L-Lysine HCl | 150 mg claimed on current merchant page | Exact current label not independently confirmed | No finished-product clinical evidence was identified in this review. [fda-supplements] |
| Magnesium Citrate | 100 mg claimed on current merchant page | Exact elemental magnesium contribution not independently confirmed | Magnesium supplements can interact with some medicines, including certain antibiotics. [magnesium] |
| Vitamin K2 (MK-7) | 50 mcg claimed on current merchant page; migration snapshot listed Vitamin K 100 mcg | Conflicting label information | Vitamin K can interact seriously with warfarin; consistent intake matters for people using warfarin. [vitamin-k] |
| Nattokinase | 100 mg / 2,000 FU claimed on current merchant page | Exact current label not independently confirmed | Human safety evidence is limited; published case reports describe serious bleeding in association with nattokinase use. [nattokinase-safety] |

Safety, interactions & who should be cautious
- People taking warfarin should not change vitamin K intake casually; NIH notes a serious interaction between vitamin K and warfarin. [vitamin-k]
- Nattokinase has fibrinolytic activity and published case reports include serious bleeding; people using anticoagulant or antiplatelet medicines should discuss use with a qualified clinician. [nattokinase-safety]
- Magnesium supplements can interact with some antibiotics and other medicines. [magnesium]
- This product is a dietary supplement, not an FDA-approved treatment for erectile dysfunction, cardiovascular disease or another medical condition. [fda-supplements]
What the evidence says
| Claim / question | Evidence assessment | Strength |
|---|---|---|
| Does the L-citrulline ingredient prove Boostaro improves erectile function? | No. A small 24-person study reported improvement with 1.5 g/day L-citrulline in mild erectile dysfunction, while the current merchant page claims 500 mg in Boostaro. This is ingredient-level evidence at a different dose and is not a trial of Boostaro. [citrulline] | limited |
| Do Vitamin C, Vitamin K and magnesium establish the advertised circulation outcome? | No. These nutrients have established physiological roles, but those roles do not establish that the finished Boostaro formula improves sexual performance or cardiovascular disease outcomes. [vitamin-c][vitamin-k][magnesium] | not established |
| Is the finished Boostaro formula clinically established? | No finished-product randomized clinical trial was identified in the sources reviewed for this pilot. The current merchant page relies mainly on ingredient-level rationale. [fda-supplements] | not established |
Potential strengths
- Current merchant page discloses a specific seven-ingredient formula and package pricing.
- The review can compare seller claims with ingredient-level evidence rather than repeating the marketing.
Important limitations
- Current online formula claims conflict with the supplied migration snapshot, so the exact current Supplement Facts panel is unresolved.
- Manufacturer/distributor identity claimed by the merchant page has not been independently verified in this pilot.
- No finished-product randomized clinical trial was identified.
Is Boostaro worth considering?
The strongest conclusion is not that Boostaro “works,” but that several listed ingredients have legitimate biological roles while the product-level evidence and current-label consistency remain insufficient. Before publication, the exact bottle label and seller/manufacturer identity should be independently reconciled; safety review is particularly important for vitamin K and nattokinase users taking blood-thinning medicines.
