Although some anecdotal beliefs exist that higher doses of vitamin C can be an alternative to birth control pills or abortion methods, experts do not recommend vitamin C for birth control or terminating a pregnancy. You may seek a doctor???s advice to know more about safe and effective birth control measures.

Some studies stated that more than the recommended levels of vitamin C could interfere with the progesterone secreted from the corpus luteum. Since progesterone prepares the endometriumiThe tissue that lines the uterus or womb for implantation and sustains the pregnancy, reduced pregnancy hormone levels may help prevent pregnancy (2).

Vitamin C intake as an alternative to birth control pills has been discussed, but there is no evidence to prove its efficacy. Hence you should consult with your OB-GYN about effective contraceptive methods.

How Much Vitamin C Should You Take To Prevent Pregnancy?

It is believed that if taken above the limit of 2000 mg per day, vitamin C can cause abortion or prevent pregnancy. However, there is no enough evidence to confirm this claim, and it is advisable to consult your OB-GYN for better abortion techniques or contraception methods.

The dosage of vitamin C is 85 mg per day for pregnant women of 19 years and above and 80 mg per day for pregnant women between the ages 14 and 18 years. The upper limit for safe consumption in both cases is 2000 mg per day (3).

The use of vitamin C as contraception for family planning to prevent pregnancy has not been studied enough to confirm its efficacy. However, some of these methods are believed to prevent pregnancy, but are not recommended by medical practitioners

  • Vitamin C tablets placed inside the vagina during intercourse can prevent the sperm from passing through the cervix by killing them.
  • Vitamin C, along with lemon juice, can probably reduce the chances of conceiving. If taken after conception, large quantities of lemon juice are likely to cause a miscarriage.

protip_icon Quick fact
Oral absorption of vitamin C decreases to less than 50% when consumed in amounts greater than 1000 mg as the intestines have a limited ability to absorb it (10).

What Are The Other Impacts Of Vitamin C Overdose?

Besides miscarriage, another serious concern of vitamin C overdose during pregnancy is scurvy. Scurvy is a condition characterized by muscle pain and bleeding or swollen gums due to vitamin C deficiency. Babies born to mothers taking around 6,000mg or more of vitamin C may suffer from rebound scurvy because there is a sudden drop in the level of vitamin C post-delivery (4). High doses of vitamin C also increase the maternal risk of developing kidney stones as excess vitamin C can potentially increase the oxalate amount in urine, leading to the formation of kidney stones. Some other health risks associated with excess consumption of Vitamin C supplementation include nausea, diarrhea, abdominal pain, and other gastrointestinal discomforts (5).

Deficiency of vitamin C during pregnancy is also believed to increase the risks for preeclampsia, a pregnancy complication characterized by high blood pressure. However, the research to support this subject is minimal (6).

Given that vitamin C as a contraceptive options lacks scientific evidence, you may consider other conventional options of abortion after consulting with your OB-GYN. These include medical abortion (abortion pills) and surgical abortion.

Medical abortion involves the administration of abortion pills. It is a course of two abortion pills, namely, mifepristoneiA medication used to cause an abortion or manage an early miscarriage and misoprostoliA medication used to treat ulcers, induce labor, and cause abortion , taken in a specific order. The misoprostol is a pack of six tablets and should be taken after the first pill, mifepristone.

In the case of surgical abortion, it may either be a vacuum aspirationiAsurgical abortion that uses gentle suction to remove the fetus through the cervix or dilation and evacuation methodiA method of abortion by cervix dilatation and the surgical evacuation of the uterus . In the first procedure, a suction device inserted through the dilated cervix is used to empty the uterus. For the dilation and evacuation method, the process is similar to vacuum aspiration, except other medical instruments and the suction are used to empty the uterus from remaining pregnancy tissues (7).

Frequently Asked Questions

1. What can happen if I take too much vitamin C while pregnant?

An excessive intake of vitamin C is seldom harmful. However, those with a family history of kidney disease should be careful since excess vitamin C acidifies the urine, increasing the risk of kidney stones (8) (9).

2. Can too much vitamin C cause congenital disabilities?

There is insufficient evidence linking excessive consumption of vitamin C to congenital disabilities or any other effects on the growing fetus (3).

3. How long does it take for vitamin C to work as a form of contraception?

There is no clinically significant study to back the claim that vitamin C may work effectively as a contraceptive pill. However, consecutively consuming large doses is believed to cause abortion or prevent pregnancy. Consult a healthcare provider for appropriate scientifically-backed contraceptive methods.

The use of vitamin C to prevent pregnancy or terminate a pregnancy lacks any scientific evidence to support it. If you do not wish to continue with the pregnancy, there are several surgical and medical alternatives that can be opted for the procedure. A risk factor associated with the overdose of vitamin C is the increased risk of miscarriage and scurvy in the mother and rebound scurvy in the baby post delivery. Therefore, it is advised that you consult with your OB-GYN about the safest procedure for abortion to avoid any future risks and complications.
