Summary
- A new Nutrients study shows that drinking 12 ounces of 100% elderberry juice daily for a week helped overweight adults activate more genes that regulate how the body uses energy after meals than a placebo
- Elderberry juice turned on processes that help the body manage energy better — making it easier to switch between burning carbohydrates and fat for fuel
- Earlier research from Washington State University showed elderberry juice improved blood sugar control, increased fat burning, and shifted energy use during meal challenges
- Practical tip: Aim for about 12 ounces of unsweetened, 100% elderberry juice daily for seven days. Check labels to avoid added sugars, as unsweetened juice still contains about 30 to 36 grams of natural sugar per eight-ounce serving
- Safety first: Never eat raw elderberries, check for medication interactions (such as immunosuppressants or diabetes drugs), and consult a healthcare provider before using if you are breastfeeding or have an autoimmune condition

| 0:22.5 | Hello and welcome to Dr. Mercola's cellular wisdom. |
| 0:26.6 | Today we're examining new research on 100% elderberry juice and how it may improve your ability to toggle between burning carbohydrates and fat, a trait known as metabolic flexibility. |
| 0:39.3 | I'm Ethan Foster. We'll look at a randomized, placebo-controlled crossover trial that asked |
| 0:45.3 | overweight adults to drink 12 ounces of unsweetened elderberry juice daily for one week, then compared |
| 0:51.3 | those results with a sugar-match placebo. |
| 0:53.3 | I'm a Lara Sky. We'll also cover what this means for you day-to-day. |
| 0:58.0 | How much juice was studied, what the gene-level data revealed, what to look for on labels, |
| 1:03.3 | and the safety steps you should follow before you start. |
| 1:06.4 | The study enrolled 20 overweight adults and kept calories and sweetness comparable by pairing |
| 1:12.2 | elderberry juice with a sugar-matched placebo. |
| 1:15.4 | Because it was a crossover design, each person served as their own control, which |
| 1:19.9 | helps isolate the specific effects of elderberry rather than differences in diet or metabolism. |
| 1:26.0 | Instead of tracking weight changes over a short week, |
| 1:28.3 | researchers analyzed blood cells with RNA sequencing |
| 1:31.3 | to see which genes turned on or off after meals. |
| 1:35.3 | They also watched standard metabolic markers |
| 1:38.3 | and gut microbiome shifts to capture how your system processes energy in real time. |
