Ingredient 5 of 8
Wild Yam in SodaPeak: How Much Is Inside and Why It Is Not a Hormone
Wild yam is the fifth of eight ingredients in SodaPeak's 1,200 mg blend, so it weighs at most 240 mg per 2 capsules. It contains diosgenin, which chemists can turn into steroids in a lab, but the human body cannot. RxList says wild yam extract does not raise DHEA in people (RxList: Wild yam), and MSK finds no progesterone conversion (MSK: Wild yam).

The basics
What is wild yam?
Wild yam is the name for several climbing vines in the Dioscorea family. Their thick roots store a plant compound called diosgenin.
The SodaPeak label lists "Wild Yam Extract (Dioscorea Opposita) Root". Dioscorea opposita is often called Chinese yam. Much of the published safety writing, including Memorial Sloan Kettering's, focuses on a related species, Dioscorea villosa (MSK: Wild yam). Findings may not transfer exactly between species.
Wild yam is not a nutrient, and it has no Daily Value. The profile table lines up the label facts with the research.
| Label name | Wild Yam Extract (Dioscorea Opposita) Root |
|---|---|
| What it is | Dioscorea opposita root · Root extract |
| Position on the label | 5 of 8 in the blend (labels list blend ingredients from most to least by weight) |
| Amount per serving (2 capsules) | Not disclosed; at most 240 mg by label math |
| Amount used in research | No useful dose; the body does not turn it into hormones |
| Strength of evidence | No hormone effect in people |
| Why it is used | Root with diosgenin, a lab starting material for steroids |
| Main caution | Estrogen-like effects: ask first with hormone-sensitive conditions. |
Label math
How much wild yam is in SodaPeak?
The label gives no number. Wild yam appears fifth in the 1,200 mg Test Boost Proprietary Blend, under one shared total.
Blend ingredients must be listed by weight, from the largest share down (FDA labeling guide ch. IV (blends)). With four heavier ingredients ahead of it, wild yam can be no more than one fifth of the blend. That works out to 1,200 divided by 5, or at most 240 mg in two capsules.
| If the first four ingredients use | Left for the last four | Most wild yam could weigh |
|---|---|---|
| 960 mg (equal shares) | 240 mg | 240 mg |
| 1,000 mg | 200 mg | 200 mg |
| 1,100 mg | 100 mg | 100 mg |
The 240 mg figure is only the top of the range. At 1 capsule a day, the ceiling halves to 120 mg. The Test Boost blend label math article walks through every position.
The big myth
Does wild yam turn into progesterone or DHEA?
No. Both RxList and Memorial Sloan Kettering say the conversion happens only in a laboratory, not inside the body (MSK: Wild yam) (RxList: Wild yam).
The idea has a real origin. Chemists can use diosgenin as a starting material for steroid compounds. That takes lab reactions, and swallowing the root does not repeat them.
In the lab
Chemists convert diosgenin into steroid compounds, step by step, with reagents (MSK: Wild yam).
In your body
No such conversion. MSK finds no evidence the body turns it into progesterone (MSK: Wild yam).
In studies
RxList says wild yam extract "will not increase DHEA levels in people", and a wild yam cream did not change progesterone (RxList: Wild yam).
Even if it did make DHEA, the payoff for men looks small. The NIH Office of Dietary Supplements reports that DHEA itself, at 100 to 150 mg a day for 8 to 12 weeks, did not raise strength, lean mass or testosterone in men (ODS: Exercise & performance supplements).
The evidence
What does the research on wild yam show?
Very little that applies to men. Most wild yam studies looked at menopause, and the results were weak or negative (MSK: Wild yam) (RxList: Wild yam).
| Use | Rating or finding | Source |
|---|---|---|
| Hot flashes | Possibly ineffective; a topical villosa cream failed in a 2001 trial | RxList, MSK (RxList: Wild yam) (MSK: Wild yam) |
| Sexual desire | Insufficient evidence | RxList (RxList: Wild yam) |
| Energy | Insufficient evidence | RxList (RxList: Wild yam) |
| Raising DHEA | Does not happen in people | RxList (RxList: Wild yam) |
| Muscle or strength in men | Not published | No study in our sources |
No trial in our sources tested wild yam for muscle, the one thing the SodaPeak bottle claims. None tested SodaPeak at all.
Marketing vs label
Why would a men's blend include wild yam?
Most likely because of the hormone story. A root linked to steroid chemistry sounds right in a blend named Test Boost. The science does not back that link.
A 2020 review in the World Journal of Men's Health looked at 50 "testosterone booster" products. Only about a quarter of their ingredients had any data showing a testosterone rise (Clemesha 2020: T-booster claims). Wild yam has none in our sources.
SodaPeak's bottle stays modest. Its only printed claim is "Supports healthy muscle*". Readers who suspect low testosterone should know it is diagnosed with two morning blood tests under 300 ng/dL plus symptoms (Urology Care: Low testosterone). The low testosterone guide explains the tests.
Safety
Is wild yam safe? Side effects and cautions
At small amounts, side effects seem uncommon. RxList notes that large amounts can cause vomiting (RxList: Wild yam). The main concern is that wild yam may act a little like estrogen.
MSK says wild yam has estrogen-like effects, so people with hormone-sensitive cancers should talk to their physician first (MSK: Wild yam). That includes men with prostate cancer or on hormone therapy. RxList also advises avoiding it with protein S deficiency, a clotting disorder (RxList: Wild yam).
- RxList lists a moderate interaction with estrogen medicines such as estradiol (RxList: Wild yam).
- MSK cites animal data linking Dioscorea villosa to long-term kidney injury (MSK: Wild yam). No human cases appear in our sources.
- Stomach upset and vomiting are more likely at high intake.

Our take
Is the wild yam in SodaPeak worth it?
No. Wild yam adds little for a man. Its fame rests on a lab process the body cannot copy, and the human studies are weak.
In its favor
- Clearly named, with species and plant part
- Few side effects at small amounts
Against it
- No conversion to DHEA or progesterone in people
- No muscle or strength data
- Estrogen-like effects
- Amount hidden; at most 240 mg
If hormones are your concern, a blood test answers the question better than any root.
In one line
What is the short answer on wild yam?
At most 240 mg, fifth in the blend, no hormone effect in people, and an estrogen caution. Judge SodaPeak on the full label, not on this one root.

FAQ
Wild yam in SodaPeak: common questions
How much wild yam is in SodaPeak?
SodaPeak does not print a wild yam amount. It is fifth in a 1,200 mg blend ordered by weight, so it can weigh at most 240 mg per 2 capsules, or 120 mg per capsule. The true share is almost certainly smaller.
Does wild yam affect testosterone?
No evidence shows that in our sources. Wild yam's diosgenin becomes steroids only in a lab, and RxList says the extract does not raise DHEA in people. SodaPeak makes no testosterone claim. See a doctor for a blood test if you have symptoms.
Is wild yam a natural progesterone?
No. Memorial Sloan Kettering says there is no evidence the human body converts wild yam's diosgenin into progesterone. Creams and capsules sold as natural progesterone based on wild yam alone rely on a lab process, not on what happens in your body.
What is Dioscorea opposita?
Dioscorea opposita is the yam species named on the SodaPeak label, often called Chinese yam. It belongs to the same plant family as Dioscorea villosa, the species most safety sources describe. The label does not say how strong the extract is.
Can men take wild yam?
Men can, but those with prostate cancer or on hormone therapy should ask first. MSK notes estrogen-like effects and advises people with hormone-sensitive cancers to talk to a physician. Our sources show no benefit for men's muscle or energy.
What are the side effects of wild yam?
Wild yam is usually well tolerated in small amounts. RxList says large amounts can cause vomiting, and it interacts moderately with estrogen medicines. MSK cites animal data on kidney injury from one species, with no human cases in our sources.
