Acerola and Ethinyl Estradiol, Drospirenone

Here is the interaction we found between these two, with the evidence behind it.

Minor

ESTROGENS

Why this applies to Ethinyl Estradiol, Drospirenone

Ethinyl Estradiol, Drospirenone falls under ESTROGENS — the group Acerola interacts with.

Theoretically, concomitant use of acerola with estrogens might increase estrogenic effects.
Acerola contains vitamin C. Increases in plasma estrogen levels of up to 55% have occurred under some circumstances when vitamin C is taken concurrently with oral contraceptives or hormone replacement therapy, including topical products. It is suggested that vitamin C prevents oxidation of estrogen in the tissues, regenerates oxidized estrogen, and reduces sulfate conjugation of estrogen in the gut wall. When tissue levels of vitamin C are high, these processes are already maximized and supplemental vitamin C does not have any effect on estrogen levels. However, increases in plasma estrogen levels may occur when women who are deficient in vitamin C take supplements.
Severity Minor Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with Yaz (ethinyl estradiol and drospirenone) and acerola. Acerola is loaded with vitamin C, and in theory high doses of vitamin C may bump up the amount of estrogen circulating in your blood. The idea is that vitamin C slows the breakdown of estrogen, so a bit more stays active. If that happened, you might notice more typical estrogen-related effects like nausea, breast tenderness, bloating, or headaches.

Honestly, this is a weak, theoretical concern. It mostly mattered in older reports involving women who were low in vitamin C to begin with. Once your vitamin C levels are normal, extra doesn't seem to change much. Eating acerola as a fruit is very unlikely to be an issue. If you take concentrated vitamin C supplements regularly, just mention it to your pharmacist or doctor.

About Acerola

What is Acerola?

Acerola
  • Vitamin C source
  • Immune support
  • Antioxidant support
  • General wellness
  • Skin health

Acerola is a small tropical fruit prized for its very high natural vitamin C content, and it is mostly used as a food-based source of vitamin C and antioxidants. While vitamin C itself has well-known roles in the body, strong human studies showing that acerola specifically treats or prevents disease are limited. It is generally considered safe in food amounts, but check with your pharmacist or doctor before using concentrated supplements.
