Short answer: maca and Tribulus are completely different plants, with different constituents and different research. There is no scientific rule that either one automatically raises testosterone or that combining them guarantees a specific result. Available human evidence remains limited and varies according to the extract, dose and context.
What is maca?
Maca (Lepidium meyenii) is a plant from the Andes that is used as food and in traditional practice. Maca preparations have been studied in several human trials relating to desire, sexual function and some measures of well-being, but the size and quality of these studies do not support firm conclusions.
A systematic review indexed on PubMed found that some small trials suggested a possible benefit, but the number of studies and participants and the methodological quality were limited. The researchers therefore concluded that the evidence was insufficient for a definite conclusion.
What is Tribulus?
Tribulus (Tribulus terrestris) is another plant that has been used in supplements marketed for vitality and sexual health. It is important to distinguish marketing from what clinical studies actually establish.
In a systematic review published in 2025 covering trials in men, researchers did not find strong evidence that Tribulus reliably increases testosterone levels. Some studies reported improvements in certain measures of sexual function, but the level of evidence remained low.
A more recent systematic review and meta-analysis of randomized trials also reported positive results in some functional measures among people with erectile dysfunction. These results do not mean that the plant is an approved treatment and cannot be generalized to every person or every preparation.
Are maca and Tribulus the same thing?
No. The difference begins with the plants themselves and extends to their active constituents and the extracts used in studies. Doses should therefore not be compared by numbers alone, and the word “extract” should not be assumed to mean a standardized formula across all products.
Does having both in a supplement mean it will raise testosterone?
No. This is one of the most commonly confused points. Particularly for Tribulus, recent clinical reviews do not show strong and consistent evidence of increased testosterone in men. Maca should likewise not be presented as a substitute for treating a diagnosed hormonal deficiency.
If there are symptoms that may relate to low hormone levels, sexual-function concerns or persistent fatigue, medical assessment is more important than relying on a dietary supplement to determine the cause.
How do you read a product containing maca and Tribulus?
- Check the scientific name of each plant.
- Check the amount of each ingredient in the stated daily serving.
- Pay attention to extract type and standardization percentage if provided.
- Do not treat the word “natural” as a guarantee of effectiveness or suitability for everyone.
- Consult a professional if you take medicines or have a chronic health condition.
Example from Herbal Vitaly
When reviewing Ushabti, it is better to view maca and Tribulus as components of a dietary-supplement formula rather than as a medicine or a guarantee of a specific hormonal result. Read the doses, directions and warnings on the packaging and official page.
Key takeaway
Maca and Tribulus are different botanical ingredients with different research bases. There are research signals of possible benefits in some contexts, but the evidence is not strong enough for broad promises, and there is no good basis for considering Tribulus a proven way to raise testosterone. Careful reading of the formula, dose and context matters more than marketing language.
