DCA (sodium dichloroacetate) Questions

DCA Questions

What is Sodium Dichloroacetate?

Sodium Dichloroacetate, also known as DCA or NaDCA, is a simple molecule that is used as an effective tool to fight various forms of cancers.  Recent research has reported tumor mass and size reduction by 70% in just three weeks.  For more information on DCA, read DCA Information.

Where can I buy DCA?

DCA, as well as other products, are available at the DCA Store.

Can DCA be taken if you’re pregnant?


While no official tests or studies have been conducted, the serious potential for birth defects is present and should be avoided.

How Long Do I Have To Take DCA?

The length of time people take DCA varies depending on many factors, for example; the type of cancer, the stage the cancer is in, how aggressive the cancer is, etc.  Due to these varying factors, it is not possible to estimate the length of treatment.

Once the cancer is completely gone and you are in remission, you may wish to consider a maintenance dose of 2-3 mg of DCA per kg of body weight (or 1 DCA capsule) per day.  This is especially important if you believe you are at risk of the cancer returning.

Calculating Dosage

How much DCA do I use?

Calculating the correct DCA dosage is very important and critical to a successful cancer treatment.  A calculation chart is available on the DCA Dosages page.

How Do I Use The Scale To Measure DCA?

DCA should be measured by weight, never by volume.  Our scales a very sensitive and measure DCA to 0.01 grams.

You can buy our digital scales here:  DCA Store

How Much Thiamine B1 Should I Take?

It is recommended that you take 750mg of Thiamine B1 Supplement per day (two Thiamine B1 capsules).

Side Effects

Does DCA have any side effects?

The side effects of DCA are much milder than most standard chemotherapy agents prescribed to cancer patients.

DCA in high dosages can cause serious side-effects, however at the correct dosage amount side effects are few and rare.  The most commonly reported side effect of using DCA is reversible damage to peripheral nerves (tingling of the extremities).

What does “reversible damage to peripheral nerves? mean?

Symptoms of peripheral nerve damage may include trembling or tingling of fingers and toes, which is called Neuropathy.  Doctors stress that this is temporary and is reversible.  Damage to the nerves in the hands and feet usually takes several weeks to develop and can be reversed when detected early.  In order to prevent or avoid peripheral neuropathy entirely, a dietary supplement of Thiamine B1 can be taken.  Thiamine can be purchased from the DCA Store.
