Is Horse Boost safe? The short answer
For most healthy adults this is a low-risk product, and the reason is the same arithmetic that makes it a weak one: nine ingredients share 82 mg. The things worth knowing are the stimulant, which is declared, and the interactions that matter at doses far above these.
| Ingredient | Amount | Side effects and cautions | Source |
|---|---|---|---|
| Caffeine | 5 mg | The only declared amount. Negligible for most adults; worth knowing if you avoid caffeine | U.S. Food and Drug Administration, “Spilling the Beans: How Much Caffeine is Too Much?” |
| Muira puama | Not published | Little human safety data at any dose | Memorial Sloan Kettering Cancer Center, “Muira Puama (About Herbs)” |
| Maca | Not published | Well tolerated as a food at far higher amounts | National Center for Complementary and Integrative Health, “Maca” |
| Catuaba | Not published | Almost no human research; the plant identity itself is inconsistent | Memorial Sloan Kettering Cancer Center, “Catuaba (About Herbs)” |
| Green tea extract | Not published | Liver injury reported with concentrated extracts at high doses | National Center for Complementary and Integrative Health, “Green Tea” |
| Ashwagandha | Not published | Thyroid, sedative and immunosuppressant interactions at studied doses | National Center for Complementary and Integrative Health, “Ashwagandha” |
| L-arginine | Not published | Lowers blood pressure at gram doses; relevant with nitrates | Memorial Sloan Kettering Cancer Center, “Arginine (About Herbs)” |
| Tribulus terrestris | Not published | Stomach upset at supplement doses | Memorial Sloan Kettering Cancer Center, “Tribulus terrestris (About Herbs)” |
| Horny goat weed | Not published | Dizziness and rapid heartbeat at real doses; avoid with heart disease | Memorial Sloan Kettering Cancer Center, “Epimedium / Horny Goat Weed (About Herbs)” |
| Added sugar | 3 g | Small, but it is a daily sweet | American Heart Association, “Added Sugars” |
The thing a hidden blend actually costs you
Safety and value are the same question here, asked from two directions.
If you have an interaction to worry about — a thyroid medicine, a blood thinner, a nitrate — the useful question is “how much ashwagandha am I taking?” On this label there is no answer. The most you can say is “at most 77 mg, probably far less”, and that is an inference, not a fact.
| If you take… | The ingredient that matters | What the label tells you |
|---|---|---|
| A thyroid medicine | Ashwagandha | Present. Amount not published. At most 77 mg |
| A blood thinner | Green tea extract | Present. Amount not published. At most 77 mg |
| Nitrates or BP medicine | L-arginine | Present. Amount not published. At most 77 mg |
| Nothing, but you avoid caffeine | Caffeine | Present, and published: 5 mg |
Stop and get help if…
- A rash, swelling or trouble breathing.
- A racing or irregular heartbeat.
- Persistent stomach pain, nausea or dark urine.
- Anything that starts when the gummy does and stops when it stops.
Call 911 for chest pain or trouble breathing. Otherwise tell your own doctor, stop the gummies, and let the order desk know on +1 (302) 200-3480. Adverse events can also be reported to the FDA through MedWatch.
Comfortable with the arithmetic? A single bottle of Horse Boost is the low-commitment way to try it.

More answers on the full FAQ page.
Does Horse Boost have side effects?
The label lists none beyond the standard warning. At these amounts side effects are unlikely — which is the same reason benefits are unlikely. The one declared active with a known effect is caffeine, at 5 mg.
Can I take it with medication?
Ask a doctor first. Green tea extract, ashwagandha and L-arginine can all interact with medicines at studied doses, and although the amounts here are far below those, your doctor should know everything you take.
Can I take more than one gummy?
No. Do not exceed the label. Doubling the serving gives you 164 mg of blend, which is still below every studied dose, while doubling the sugar and the caffeine.
Is it safe if I am sensitive to caffeine?
There is 5 mg per gummy. For most people that is negligible, but if you avoid caffeine for a medical reason you should know it is there, because none of the marketing images mention it.
Is it vegetarian?
Yes, on the evidence of the label. The other-ingredients line is printed in full and the gelling agent is apple pectin, not gelatin. That is the first thing to check on any gummy, and this one passes.
