Based on the evidence available in Pillser's research database, there is not sufficient evidence specifically linking black caraway oil (black seed oil / Nigella sativa) to lowering creatinine levels.

Here's what I can tell you:

• Pillser's research database does contain studies on black seed (as a whole food) for several health outcomes — including reducing body weight, blood cholesterol, and fasting blood glucose, as well as effects on testosterone and thyroid function¹. However, creatinine levels or kidney function are not among the health outcomes studied for black seed in the database.

• When looking specifically at reduced serum creatinine levels as a health outcome, the supplements with the most evidence in Pillser's database are Red Sage (1 study, all beneficial), Thistle, and Lactobacillus rhamnosus — not black seed oil².

• For stable kidney function, the only supplement with recorded data in Pillser's database is a specific probiotic strain, not black seed oil³.

In short: While black seed oil has been studied for various health benefits, there is currently insufficient evidence in the available research to conclude that it helps lower creatinine levels. If you're looking for supplements that may support kidney function or creatinine levels, other options like Red Sage have some preliminary evidence, though the research is still very limited overall.
