Boostaro vs Blackwood Tea: 2026 Comparison
By B Mishra | Last checked: Boostaro August 29, 2026 · Blackwood Tea August 29, 2026
75/100
61/100
Boostaro and Blackwood Tea take different approaches to male wellness. Boostaro uses a clearly labelled capsule formula, while Blackwood Tea offers a broader herbal blend in a simple daily tea. Boostaro is the stronger overall choice, but Blackwood Tea may suit men who prefer a drink instead of capsules.
Boostaro is a seven-ingredient capsule with every dose printed on the label, including 1,200 mg of L-Citrulline. That clear dosing is its biggest advantage. Blackwood Tea combines 19 herbs and nutrients in a once-daily tea. Its formula includes several popular male wellness ingredients, but the individual amounts are not published. Boostaro scores higher for clarity and dose confidence, while Blackwood Tea earns credit for variety, convenience and its generous advertised guarantee.

At a Glance: Who Wins Which Category
Boostaro leads because its complete label makes the formula easier to judge and compare with published research. Blackwood Tea earns solid marks for its wide ingredient range, tea format, equal bundle pricing and stronger advertised refund offer. Both products use ingredients with a sensible male wellness rationale, although neither complete formula has been tested in a published clinical trial.
A badge reading “Tie” means the two products were within a point of each other or the evidence was genuinely comparable: not a rounding shortcut.
What Is Boostaro?
Boostaro is a two-capsule-daily supplement built around seven ingredients, led by a full 1,200 mg dose of L-Citrulline and 1,200 mg of L-Lysine, sold through the seller’s own checkout (goboostaro.com, processed by retailer BuyGoods) and promoted by an affiliate review site, boostaro.org, which openly identifies itself as independent and not the manufacturer.
Every ingredient amount is printed on the Boostaro label, with no proprietary blend hiding the doses. The formula combines amino acids linked to the nitric oxide pathway with CoQ10, magnesium, vitamin C and vitamin K2. The checkout is processed by BuyGoods, although the page could provide clearer details about the company behind the Boostaro brand.
What Is Blackwood Tea?
Blackwood Tea is a once-daily herbal tea bag containing 19 named ingredients, sold through a single long-form sales page (tryblackwoodtea.com) that frames the product around a personal-narrative story and a “venous leakage” theory of erectile difficulty, and checks out through the same retailer used for Boostaro, BuyGoods.
Blackwood Tea names all 19 ingredients but does not show their individual amounts. The page also does not clearly identify a separate manufacturer. Its claims about 73,000 reviews, university studies and zero side effects appear on the seller’s page without enough supporting detail to confirm them independently.
How Do Boostaro and Blackwood Tea Claim to Work?
Both products lean on the same broad idea: supporting blood flow to support sexual performance: but they tell very different stories about the mechanism, and only one of them backs the story with a dose you can check against research.
Venous leakage can contribute to erectile difficulty, and ingredients such as citrulline and arginine have genuine research linked to nitric oxide and blood flow. However, sexual performance problems can also involve hormones, nerves, stress, medication or wider cardiovascular health. Boostaro makes the more measured circulation-support claim. Blackwood Tea tells a stronger venous-leak story, which should be viewed as marketing rather than a medical diagnosis.
Ingredient Overlap: Boostaro vs Blackwood Tea
Only one ingredient is genuinely shared between the two formulas at a named, comparable level: L-Citrulline. Boostaro states its 1,200 mg dose; Blackwood Tea, like all 19 of its ingredients, discloses no amount at all. Everything else in each formula is unique to that product, which shifts most of this comparison onto how much each seller is willing to show you.
Shared Ingredients
| Ingredient / form | Boostaro dose | Blackwood Tea dose | Human research context | Evidence grade | HealthyPa assessment |
|---|---|---|---|---|---|
| L-Citrulline | 1,200 mg | Not disclosed | A small randomized, placebo-controlled pilot study combined 800 mg/day citrulline with 300 mg/day transresveratrol in men on PDE5 inhibitors and reported improved erectile-function scores over placebo (Shirai et al., Sexual Medicine 2018). | B/C: supportive small human pilot, combined with another compound | Boostaro’s dose is disclosed and in a comparable range to research amounts. Blackwood Tea’s amount is unknown, so it cannot be compared to any research dose. |
Unique to Boostaro
| Ingredient / form | Dose | Human research context | Evidence grade | HealthyPa assessment |
|---|---|---|---|---|
| L-Lysine | 1,200 mg | Human research centers on cold-sore recurrence and collagen/calcium metabolism, not sexual performance. | D/U for this use | Disclosed dose, but a thin rationale for this specific product category. |
| Coenzyme Q10 | 100 mg | Studied mainly for heart-failure support and statin-related symptoms at 100–300 mg/day. | B for general cardiovascular use; C/D for sexual performance directly | Reasonable general-health dose, not product-specific evidence. |
| Magnesium | 200 mg | Established role in nerve, muscle and cardiovascular function; the adult male RDA is 400–420 mg/day (NIH ODS). | B for general health; U for a sexual-performance claim specifically | A meaningful partial daily contribution, general-health rationale. |
| Vitamin C | 100 mg | Antioxidant with a role in collagen and vascular health; well above the 90 mg/day adult male RDA. | B for general antioxidant support; U for sexual performance | Reasonable disclosed dose, general-health rationale. |
| Vitamin K2 | 100 mcg | Role in calcium regulation, bone and vascular health; the significant issue is interaction with vitamin-K antagonist blood thinners. | C for general cardiovascular/bone support; U for sexual performance | Disclosed dose; main practical relevance is the interaction flag (see Safety). |
| L-Proline | 200 mg | Used in collagen synthesis relevant to vessel structure; direct human sexual-performance research is essentially absent. | D/U | Disclosed dose, structural rather than direct evidence. |
Unique to Blackwood Tea
| Ingredient / form | Dose | Human research context | Evidence grade | HealthyPa assessment |
|---|---|---|---|---|
| Tongkat Ali (Eurycoma longifolia) | Not disclosed | A 2022 systematic review and meta-analysis of randomized trials found a significant increase in total testosterone with supplementation (Leisegang et al., Medicina 2022). Reviews also warn that some commercial Tongkat Ali products are adulterated with undeclared PDE5-inhibitor drugs. | B for testosterone; U for this specific product | The most evidence-backed ingredient in this formula in principle, undermined by having no disclosed dose or standardization. |
| Horny Goat Weed / icariin | Not disclosed | Icariin shows PDE5-inhibitor-like activity in laboratory and animal models; robust human clinical evidence is limited. | D: mechanistic/animal, limited human data | Mechanistically interesting, unproven in people at any known dose here; relevant to Safety given its mechanism. |
| Beetroot extract | Not disclosed | Dietary nitrate has reasonable evidence for modest blood-pressure reduction via the nitric-oxide pathway. | B for blood pressure/exercise; U for sexual performance specifically | Plausible mechanism, no disclosed dose or direct sexual-performance trial. |
| L-Arginine | Not disclosed | Direct-ED trial evidence exists at high doses, around 5–6 g/day, far above what an undisclosed amount in a tea bag would likely deliver. | B at high, disclosed clinical doses; U here | Without a stated amount, there’s no way to know whether the content is anywhere near supportive research doses. |
| Guarana / Green Tea / Oolong Tea | Not disclosed | All three are caffeine sources with well-documented stimulant and cardiovascular effects; relevance to sexual performance specifically is indirect. | Established stimulant pharmacology; U for this product’s caffeine content | An undisclosed daily caffeine load is the clearest safety gap in this formula (see Safety). |
| Asian Ginseng / Siberian Ginseng | Not disclosed | Asian ginseng has some human evidence for erectile function at standardized 600–1,000 mg/day doses; Siberian ginseng research centers on stress/fatigue. | C for Asian ginseng at disclosed doses; U here | Plausible ingredient choice, undisclosed amount prevents comparison to research doses. |
| Muira Puama, Catuaba, Tribulus Terrestris | Not disclosed | Traditional aphrodisiac herbs; modern human trial evidence is sparse, and Tribulus trials generally show little effect on testosterone. | C/D | Traditional-use rationale rather than strong modern clinical evidence. |
| Cinnamon Bark, Garcinia Cambogia, Dandelion Leaf, Orange Peel, Lemongrass, Ginger Root | Not disclosed | Research base is mainly in metabolic health, diuretic/potassium content or general antioxidant use, not sexual performance. | D/U for this use | Read more like general-wellness tea ingredients; Garcinia Cambogia carries a known, if uncommon, liver-safety signal worth flagging. |
Does Either Finished Product Have Direct Evidence?
Boostaro: No. This research found no published trial testing the finished, seven-ingredient Boostaro formula itself. The strongest supporting evidence sits at the ingredient level, particularly the disclosed 1,200 mg L-Citrulline dose, which sits in a range used in small human pilot research on erectile function.
Blackwood Tea: No published trial has tested the complete 19-ingredient tea. Several individual ingredients have useful research behind them, especially Tongkat Ali, ginseng, beetroot, L-Arginine and L-Citrulline. The university references on the sales page do not include direct citations, so they should not be treated as proof of results for the finished tea.
Claimed Benefits Scorecard
| Product | Seller claim | Evidence found | Confidence | Verdict |
|---|---|---|---|---|
| Boostaro | “7 clinically-studied ingredients” supporting blood flow and energy | Ingredient-level human research for citrulline; thinner rationale for lysine, proline and K2 | Moderate for the lead ingredient, low for several supporting ones | Defensible structure/function framing, not a proven outcome |
| Blackwood Tea | Supports blood flow and male performance through a broad herbal blend | Several ingredients have useful research, but the finished blend and individual amounts have not been tested publicly | Moderate | A promising ingredient mix, but buyers should keep expectations sensible |
Side Effects and Safety
Boostaro safety notes
The clearest interaction concern is Vitamin K2: it can interact with vitamin-K antagonist blood thinners such as warfarin, so anyone on that class of medication should talk to a doctor before starting Boostaro. Ingredients that support circulation are also worth mentioning to a doctor if you’re being treated for blood pressure. None of the doses used (1,200 mg citrulline, 1,200 mg lysine, 100 mg CoQ10, 200 mg magnesium, 100 mg vitamin C, 100 mcg vitamin K2, 200 mg proline) are unusually high compared with general supplement use, and the seller does not claim the product is free of side effects. If erectile or circulation issues have persisted for a while, that’s worth a medical evaluation alongside, not instead of, trying a supplement.
Blackwood Tea safety notes
Blackwood Tea contains guarana, green tea and oolong tea, so it may contain caffeine. Caffeine-sensitive users should ask the seller for the total amount before buying. The formula also combines Horny Goat Weed, beetroot, citrulline and arginine, which may affect some of the same circulation pathways involved with ED medicines and nitrate heart medicines. Speak with a doctor before use if you take sildenafil, tadalafil, vardenafil, nitrates or blood-pressure medication. Anyone with liver concerns should also ask for medical advice because Garcinia Cambogia has been linked to rare liver problems.
Neither this comparison, nor either brand’s marketing, replaces advice from a qualified healthcare professional, particularly if you take medication, have an existing condition, or are pregnant or breastfeeding.

Customer Feedback and Complaints
Boostaro
Source: boostaro.org’s own buyer-feedback summary (not an independent platform) | Checked: August 29, 2026
Buyers are likely to appreciate the simple two-capsule routine and the savings on larger packages. Reported complaints mainly involve shipping delays, tolerance, billing questions and refund contact. Feedback found under other Boostaro storefront names could not be confidently linked to the BuyGoods checkout used here, so it should be read with caution.
Blackwood Tea
Source: tryblackwoodtea.com’s own claimed review count (not an independent platform) | Checked: August 29, 2026
The seller highlights more than 73,000 reviews and includes three customer stories. That figure is not linked to an independent review platform, so it is better treated as seller-provided feedback rather than a verified customer count.
Price, Refunds and Where to Buy
Boostaro and Blackwood Tea are priced identically at $69 for one unit, $59/unit for three, and $49/unit for six: which works out to the same $1.63–$2.30 per serving on both sides. Both advertise a 60-day money-back guarantee and both check out through the same retailer, BuyGoods. The real difference is what you’re paying that price for: a labeled formula on one side, an undisclosed one on the other.
| Item | Boostaro | Blackwood Tea |
|---|---|---|
| Starting price | $69 (1 bottle) + $9.99 shipping | $69 (1-month box), shipping not itemized on the page reviewed |
| Price per serving | $1.63 (6-bottle) to $2.30 (1-bottle) | $1.63 (6-month) to $2.30 (1-month), assuming ~30 bags/box |

Full Category Scorecard
Boostaro scores 75/100 and Blackwood Tea scores 61/100. Boostaro takes the lead because every ingredient amount is stated, its key doses can be compared with published research, and its capsule routine is simple. Blackwood Tea still earns a fair score for its broad herbal formula, convenient tea format, competitive pricing and generous advertised guarantee. Its main weakness is the lack of individual ingredient amounts.

Who Should Choose Boostaro, and Who Should Choose Blackwood Tea?
Choose Boostaro if…
You prefer capsules, want every ingredient amount clearly stated, and value a focused formula built around 1,200 mg of L-Citrulline. Boostaro is the easier product to assess and the stronger choice for buyers who care about dose transparency.
Choose Blackwood Tea if…
You dislike capsules and would rather make one tea each day. The 19-ingredient blend includes Tongkat Ali, ginseng, beetroot, L-Arginine and L-Citrulline, giving it a broad male wellness focus. The main trade-off is that individual doses and total caffeine are not shown, so it is less suitable for anyone who wants exact label detail.
Neither product has been tested as a finished formula, and neither should replace an evaluation of the underlying cause of erectile or sexual-performance concerns, which can include vascular, hormonal, neurological, psychological or medication-related factors a supplement or tea cannot diagnose.
Pros and Cons
Boostaro
Pros
Every ingredient dose disclosed; lead ingredient (L-Citrulline) at a research-comparable amount; simple two-capsule routine; 60-day guarantee; multi-bottle pricing genuinely lowers cost per serving.
Cons
No published trial on the complete formula; some supporting ingredients have less direct research for male performance; the brand could provide clearer manufacturer information.
Blackwood Tea
Pros
Easy once-daily tea format; broad 19-ingredient blend; includes Tongkat Ali, ginseng, beetroot, L-Arginine and L-Citrulline; competitive bundle pricing; generous advertised 60-day guarantee.
Cons
Individual ingredient amounts are not published; total caffeine is not stated; the sales page uses stronger claims than the available product evidence supports; clearer manufacturer details would improve buyer confidence.
Frequently Asked Questions
Is Boostaro or Blackwood Tea better?
Boostaro scores higher across seven of eight scorecard categories, mainly because it discloses every ingredient dose while Blackwood Tea discloses none. Neither has a finished-product trial, so “better” here means better documented and more conservatively marketed, not proven to outperform the other for actual results.
Which is cheaper, Boostaro or Blackwood Tea?
They’re priced identically at every tier reviewed: $69 for one unit, $59/unit for three, $49/unit for six, working out to $1.63–$2.30 per serving on both sides.
Can I take Boostaro and Blackwood Tea together?
Neither this comparison nor either brand tests that combination. Stacking them would combine two separate, undisclosed-in-parts nitric-oxide-pathway formulas plus undisclosed caffeine: a combination worth running past a doctor rather than assuming is fine, especially if you take any heart, blood-pressure or ED medication.
Does Boostaro contain stimulants?
No caffeine or other stimulant is listed among Boostaro’s seven disclosed ingredients.
Does Blackwood Tea contain caffeine?
The formula lists guarana, green tea and oolong tea among its 19 ingredients: all caffeine sources: but does not disclose how much caffeine the finished tea actually contains.
Is Boostaro FDA approved?
No. Dietary supplements are not FDA-approved for safety or effectiveness, and Boostaro is not an exception.
Is Blackwood Tea’s “73,000 reviews” claim real?
Independent checks could not verify it. No independent review platform carrying a matching count was found; the figure appears only within the seller’s own sales page.
Which ingredient do both products share?
L-Citrulline is the only ingredient named by both. Boostaro discloses 1,200 mg; Blackwood Tea discloses no amount.
Do either of these products cure erectile dysfunction?
No. Neither product is approved to diagnose, treat, cure or prevent any disease, and erectile dysfunction can have several underlying causes that a supplement or tea cannot address on its own. Persistent symptoms are worth discussing with a doctor.
Who sells Boostaro and Blackwood Tea?
Both products are checked out through the same retailer, BuyGoods Inc. Neither page reviewed clearly names a separate manufacturer behind the brand.
What’s the refund window for each product?
Both advertise a 60-day money-back guarantee. Blackwood Tea also says buyers may keep the product and receive a free bonus tea after an approved refund. Read the live checkout terms before ordering because conditions can change.
Is Tongkat Ali in Blackwood Tea worth it if the dose isn’t stated?
Tongkat Ali has real supportive human research for testosterone at standardized, disclosed doses used in trials. Without knowing how much (or what standardized extract) is actually in Blackwood Tea, there’s no way to judge whether the amount you’re getting is anywhere near what that research used.
Final Notes
Boostaro is the better overall choice at 75/100. Its fully stated doses, focused formula and simple capsule routine make it easier to understand and use with confidence. Blackwood Tea scores 61/100. It offers a convenient tea format, a wide mix of popular ingredients and a strong advertised guarantee, but loses points because the individual doses and caffeine level are not published.
Choose Boostaro for clearer dosing. Choose Blackwood Tea if the tea format matters more to you and you accept the lighter label detail.
