Is SynaBoost worth it?
Doesn't add up (4.1/10). SynaBoost names four ingredients, Bacopa monnieri, Huperzia serrata, Rhodiola rosea and L-tyrosine, but the page text we read gives no amount for any of them and does not name a manufacturer. That matters because they are not equal: bacopa has modest trial support at about 300 mg a day of standardized extract over 12 weeks, while huperzine from Huperzia acts on the enzyme that breaks down acetylcholine and can interact with medicines. Without amounts you cannot tell whether the capsule carries a studied dose of either. The page cites 19 references on the gut microbiome, cognition and the ingredients, but none is a trial of this capsule. The advertised $69 becomes $78.95 at the Digistore24 checkout once shipping is added. The 60-day refund is the one concrete protection.

What is SynaBoost?
SynaBoost is a capsule supplement marketed for memory function, mental sharpness and concentration. The page calls it non-habit forming, stimulant-free and all-natural. It is offered as 1, 3 or 6 bottles (30, 90 or 180 days).
The ingredients named in the text we read are Bacopa monnieri, Huperzia serrata, Rhodiola rosea and L-tyrosine. No supplement facts panel was found, and the number of capsules per bottle was not stated.
The page lists three customer testimonials and 19 references. No doctor endorsement is shown. It is sold through Digistore24 on this link; no company is named.
Format: Capsule supplement; capsules per bottle not stated. Sold by: SynaBoost (sold through Digistore24; manufacturer not named on the page).
What is on the SynaBoost label?
Each row compares what the label or sales page states with what published research used. When an amount is missing, there is nothing to compare, and we say so.
Four ingredients are named, no amount is printed for any of them, and no supplement facts panel or manufacturer was found in the page text we read.
Do the SynaBoost claims hold up?
Supports memory function and cognitive clarity
Bacopa has modest human evidence at studied doses. This page gives no dose, and no trial of the finished capsule is cited.
19 references
The references cover gut microbiome, cognitive health and the individual ingredients. They do not show that this capsule, at its undisclosed amounts, does anything.
Non-habit forming, no stimulants, all-natural
"All-natural" does not mean safe with medicines. Huperzine in particular has a real drug-like action.
Price $69 per bottle
At checkout the single bottle costs $78.95 after $9.95 shipping and handling.
How much does SynaBoost really cost?
| Option | Total | Per month | Shipping |
|---|---|---|---|
| 1 bottle | $78.95 | $78.95 | $9.95 on the order form ($69.00 + $9.95) |
| 3 bottles | $177 | $59 | Stated as free on the page; not confirmed at checkout |
| 6 bottles | $294 | $49 | Free US shipping |
One bottle is $69 on the page and $78.95 at checkout. Three bottles are $177 ($59 each) and six are $294 ($49 each). That is $49 to $69 a month before shipping on a single bottle.
Buying six saves about $20 a month against one bottle, but that is $294 up front for a product with no disclosed doses. Start with one bottle if you try it.
The page shows list prices of $147, $490 and $980 for the packs. We would ignore them and compare only what the order form asks you to pay.
The Digistore24 order form for one bottle showed $69.00 plus $9.95 shipping and handling, $78.95 in total, rechecked on 26 September 2026. The page lists $69 for one bottle, so the real entry cost is about $10 higher. The 3 and 6 bottle packs are described as shipping free.
