SodaPeak Side Effects and Drug Interactions by Ingredient

Rarer risks include heart rhythm changes, low blood pressure, bleeding with blood thinners, and interactions with lithium, digoxin and diabetes medication. Talk to your doctor first if you take any of these.

The short version
What are the side effects of SodaPeak?
The common side effects are likely to be mild: an upset stomach, nausea, headache, dizziness or feeling hot and sweaty. They come from research on each ingredient, because SodaPeak itself has never been tested.
The rarer risks deserve your attention first. Horny goat weed, the first and largest ingredient, has case reports of an irregular heartbeat (MSK: Epimedium). It may also lower blood pressure and slow clotting (RxList: Horny goat weed). Saw palmetto adds bleeding risk with blood thinners (MSK: Saw palmetto).
Eight ingredients share a 1,200 mg blend, so each dose is probably modest, but no single amount is printed. The FDA reminds buyers that supplements can have strong effects (FDA 101: Dietary supplements).
Begin with one capsule a day so a reaction shows at the lower dose. Two a day is the label maximum.

Medicines
What medicines interact with SodaPeak?
At least six medicine groups interact with SodaPeak's herbs. If you take any of them, ask your doctor or pharmacist before the first capsule.
| Medicine | Ingredient | What could happen |
|---|---|---|
| Blood thinners (warfarin, clopidogrel and others) | Saw palmetto, horny goat weed, nettle root | More bruising or bleeding (MSK: Saw palmetto) (RxList: Horny goat weed); nettle's vitamin K may affect warfarin (RxList: Stinging nettle) |
| Blood pressure medicines | Horny goat weed, nettle root | Blood pressure may drop too low (RxList: Horny goat weed) (RxList: Stinging nettle) |
| Diabetes medicines | Nettle root | Blood sugar may drop too low (RxList: Stinging nettle) |
| Lithium | Nettle root, sarsaparilla | Higher lithium levels from a water-pill effect (RxList: Stinging nettle) (RxList: Sarsaparilla) |
| Digoxin | Sarsaparilla | The body may absorb more digoxin (RxList: Sarsaparilla) |
| Drugs that affect heart rhythm (QT) | Horny goat weed | Added rhythm risk (RxList: Horny goat weed) |

Horny goat weed may also speed up CYP3A4, a liver enzyme that clears many prescriptions (MSK: Epimedium).
Heart and blood pressure
Can SodaPeak affect your heart or blood pressure?
It might, mainly because of horny goat weed. Memorial Sloan Kettering reports a 66-year-old man with heart failure who was hospitalized with a new irregular heartbeat and hypomania after two weeks of daily use (MSK: Epimedium). MSK advises people with heart disease to avoid the herb.
RxList adds that it may lower blood pressure (RxList: Horny goat weed), and nettle root can too (RxList: Stinging nettle). That can mean dizziness when you stand up.
Chest pain, a racing or irregular heartbeat, fainting or trouble breathing need urgent medical care. Stop SodaPeak and call 911 or go to an emergency room.
Erection problems can also be an early sign of clogged arteries, high blood pressure or diabetes, the NIH notes (NIDDK: ED symptoms & causes). That calls for a checkup, not a supplement.
Bleeding
Is SodaPeak safe with blood thinners?
Ask your doctor first, because two of its herbs may add to bleeding risk. Memorial Sloan Kettering says not to take saw palmetto with warfarin or other blood thinners, and lists bleeding case reports (MSK: Saw palmetto). RxList says horny goat weed slows clotting (RxList: Horny goat weed).
- Watch for easy bruising, nosebleeds, bleeding gums or dark, tarry stools.
- Stop SodaPeak before planned surgery, as RxList advises for horny goat weed, and tell your surgeon and dentist (RxList: Horny goat weed).
Hormones
Can SodaPeak affect your hormones?
Several of its herbs have hormone-related cautions, so it is possible.
Horny goat weed and wild yam
Both have estrogen-like activity, per MSK (MSK: Epimedium) (MSK: Wild yam). People with hormone-sensitive cancers should ask their physician first.
Saw palmetto
It blocks an enzyme that converts testosterone, and decreased libido is a listed side effect (MSK: Saw palmetto).
Tongkat ali
Interacts with testosterone and prostate-cancer antiandrogens, per WebMD (WebMD: Eurycoma longifolia).
Urinary pain with fever needs prompt care, says the NIDDK (NIDDK: Enlarged prostate (BPH)).
Liver and kidneys
Can SodaPeak harm your liver or kidneys?
No liver or kidney harm has been reported for SodaPeak, but a few ingredients carry rare warnings. LiverTox records one liver injury case tied to tongkat ali (LiverTox: Tongkat ali).
RxList advises avoiding sarsaparilla with kidney problems (RxList: Sarsaparilla), and nettle root carries a kidney caution (RxList: Stinging nettle).
Stop and call your doctor if you notice dark urine, yellow skin or eyes, belly pain or unusual tiredness.

FAQ
SodaPeak side effects FAQ
What are the most common side effects of SodaPeak?
The most likely ones are mild: stomach upset, nausea, headache, dizziness, or feeling hot and sweaty. These come from studies of the individual herbs, since SodaPeak has not been tested. Start with one capsule a day and stop if a reaction does not settle.
Is SodaPeak safe with blood pressure pills?
Ask your doctor first. Horny goat weed and nettle root may lower blood pressure, and with blood pressure medicine it could drop too low. Signs include dizziness or fainting when you stand. Bring the SodaPeak bottle so your doctor can read the full label.
Does SodaPeak cause a fast heartbeat?
It could in rare cases. Horny goat weed, SodaPeak's first ingredient, has case reports of rapid or irregular heartbeat, including a man hospitalized after two weeks of use. Stop taking it and get medical care right away if your heart races or skips.
Can SodaPeak lower my sex drive?
It is possible. Saw palmetto, the third ingredient, has decreased libido listed as a side effect by Memorial Sloan Kettering, because it blocks an enzyme that converts testosterone. If you notice a drop after starting SodaPeak, stop it and see whether it returns.
Should I stop SodaPeak before surgery?
Yes. RxList advises stopping horny goat weed before surgery because it slows clotting, and saw palmetto has bleeding case reports during and after operations. Tell your surgeon and dentist about every supplement you take.
