Maca root, royal jelly, wild yam tea and detox teas have weak or no evidence for fertility. DHEA and vitex have a place only in narrow cases: DHEA in selected cases of very low ovarian reserve under strict medical guidance, vitex possibly for a short luteal phase, with limited evidence. They are not necessarily harmful, but they are not worth spending a lot on if your nutritional base is already good.
Several substances are sold as “miracles” for fertility but have very weak or no evidence. It's not that they're harmful; it's just not worth spending a lot on them if your nutritional base is already good.
| Supplement | What the evidence shows |
|---|---|
| Maca root | Little human evidence, mostly for libido |
| DHEA | Only in selected cases of very low ovarian reserve, under strict medical guidance |
| Royal jelly | No solid studies, and a risk of allergic reaction |
| Wild yam tea | Promises a “natural hormone” with no proof |
| Vitex (chasteberry) | May help in cases of short luteal phase, but the evidence is limited |
| Cleansing/detox teas | No evidence of any benefit |
The list mixes two kinds of product. Maca, royal jelly, wild yam tea and detox teas have nothing solid behind the fertility promise, and royal jelly adds a risk of allergic reaction. Maca's small body of human evidence is mostly about libido, not about getting pregnant.
DHEA and vitex are different: each has one narrow situation where it may play a role. DHEA is reserved for selected cases of very low ovarian reserve, and only under strict medical guidance, never as a self-prescribed booster. Vitex may help with a short luteal phase, but even there the evidence is limited.
The same pattern repeats beyond this list. Fenugreek and ashwagandha are also sold as “essential for fertility”, with minimal solid human evidence. An influencer earning a commission on a sale is not scientific evidence.
The same chapter lists the supplements that do have solid evidence, each for a defined situation:
Before any of them comes the nutritional base. That is the condition the book attaches to its warning: with a good nutritional base, the trendy extras are simply not worth spending a lot on.
Popular supplements without strong evidence close Chapter 22 of Map to the Positive, in Station III (Optimization). The chapter's core is the opposite list: the supplements with solid evidence, with doses, forms, and the 90 to 180 days they need before trying. Station III also has a whole chapter on what doesn't work and what it is costing you.
