The basics01
What is wild yam in SodaPeak?
Wild yam in SodaPeak is a root extract, printed on the label as "Wild Yam Extract (Dioscorea Opposita) Root". It is the fifth of eight lines in the blend.
The Supplement Facts list one "Test Boost Proprietary Blend" of 1,200 mg per serving of 2 capsules. Wild yam follows horny goat weed, tongkat ali, saw palmetto and nettle root. Sarsaparilla, orchic substance and boron come after it.
Sellers often market wild yam as a "natural hormone" herb. The bottle makes no hormone claim. Its only claim is "Supports Healthy Muscle*", and the asterisk points to the FDA statement on the back.
Label math02
How much wild yam is in SodaPeak?
SodaPeak does not print the amount. By label order, wild yam can weigh at most 240 mg per serving of 2 capsules.
A proprietary blend lists its ingredients in descending order of predominance by weight, and the blend line shows only the combined weight (21 CFR 101.36 (Supplement Facts, proprietary blends)). So the first five lines must each weigh at least as much as line 5. Five lines at 240 mg already use all 1,200 mg.
That is 1,200 divided by 5. It is a ceiling, not an amount. An even split would give 150 mg to every line, and wild yam could weigh anywhere from a trace up to 240 mg.
| Line | Ingredient | At most (mg) |
|---|---|---|
| 4 | Nettle root | 300 |
| 5 | Wild yam | 240 |
| 6 | Sarsaparilla | 200 |
The compound03
Does wild yam turn into hormones in the body?
No evidence shows that it does. The main compound in wild yam is diosgenin, a steroid saponin, and the body is not shown to convert it into hormones (MSK, Wild Yam).
The idea comes from a lab fact. Chemists have used diosgenin as a raw material to make synthetic progesterone. That is a factory process with several steps. The same source finds no evidence that the body does it.
Progesterone is also not testosterone, and the source finds nothing for testosterone or muscle claims.
A plant compound that can be changed into a hormone in a lab is not the same as a hormone supplement. Wild yam is a source for the first, with no proof of the second.
Research04
What does research say about wild yam?
Human studies of wild yam are few, small and mixed (MSK, Wild Yam). None tested wild yam as one line of a capsule blend.
In one trial, an oral formula helped menopausal symptoms. In another, a topical formula did not. Neither measured muscle or testosterone.
The wider picture for over-the-counter testosterone boosters is weak support for their claims (Clemesha et al. on T-booster claims (SMSNA summary)). No trial has tested SodaPeak itself.

Is wild yam in SodaPeak safe?
Wild yam is described as having estrogenic effects, so people with hormone-sensitive cancers should ask a physician before using it (MSK, Wild Yam).
Estrogenic means acting a little like estrogen. The source gives no safe dose for this blend.
Supplements are not approved by FDA before sale (FDA, Information for Consumers on Dietary Supplements). Side effects are most likely at high doses or when several supplements are combined (NIH ODS, Dietary Supplements: What You Need to Know). SodaPeak combines eight lines, and the other seven have their own notes on SodaPeak side effects.
If you take a hormone treatment or have a hormone-sensitive condition, ask your doctor or pharmacist before using SodaPeak. Never change a prescribed dose because of a supplement.

Claims06
Does wild yam support healthy muscle?
No source we read shows that wild yam supports muscle. The bottle claims "Supports Healthy Muscle*" for the blend as a whole, not for this line.
What the research does support is simple. Muscle-strengthening work on 2 or more days a week plus 150 minutes of activity (CDC, Adult Physical Activity Guidelines), adults sleeping 7 or more hours (CDC, About Sleep), and enough protein (Harvard Nutrition Source, Protein).
Better places to put effort
- Lift on 2 or more days a week
- Sleep 7 hours or more
- Ask a doctor for testing if low drive or energy lasts for weeks

What should you ask before buying a blend with wild yam?
Ask the seller for the amount of each line, and ask your doctor if any of your medicines or conditions are hormone-related.
The label prints only the 1,200 mg total. A call to the order desk at +1 (302) 200-3480 is the only way to learn more.
FAQ08
SodaPeak questions people ask
Is wild yam a natural source of progesterone?
No. Diosgenin from wild yam has been used in labs as a raw material for synthetic progesterone, but there is no evidence that the human body converts it into progesterone or any other hormone (MSK, Wild Yam).
What is the label name of wild yam in SodaPeak?
The Supplement Facts print it as Wild Yam Extract (Dioscorea Opposita) Root. It is the fifth of eight lines in the Test Boost Proprietary Blend, listed after nettle extract and before sarsaparilla.
How many milligrams of wild yam are in one SodaPeak capsule?
The label does not say. By label order, wild yam can weigh at most 240 mg per serving of 2 capsules, so at most about 120 mg per capsule. The true amount could be far lower.
Is wild yam safe for men with hormone concerns?
Ask a doctor first. Wild yam is described as having estrogenic effects, and people with hormone-sensitive cancers should check with a physician (MSK, Wild Yam). We found no study of wild yam in men at SodaPeak's unknown amount.
Does diosgenin help build muscle?
No study we read links diosgenin to muscle. The source on wild yam says nothing supports muscle or testosterone claims (MSK, Wild Yam). Strength comes from lifting, protein and sleep, which have far better evidence.
Why is wild yam in a blend called Test Boost?
Wild yam is marketed as a natural hormone herb, which fits a blend with that name. The evidence does not back the idea, and the label itself makes no testosterone claim, only 'Supports Healthy Muscle*'.
