Phosphatidylserine Side Effects and Safety

✅ Medically Reviewed by: Dr. Alexandru-Theodor Amarfei, M.D. | Coordinator, Geriatric Medicine – CHIC Unisanté, France

Before you start any new supplement, you want to know: "Is this safe?" "Will it interact with my meds?" "What happens if I take too much?"

When it comes to Phosphatidylserine (PS), the news is overwhelmingly positive. Because PS is a substance your body naturally produces (it makes up a huge portion of your brain mass), it is considered generally recognized as safe (GRAS) by the FDA. However, there are a few nuances you should know.

Common Side Effects (Rare & Mild)

Most clinical studies using doses up to 600mg per day report zero side effects. However, in sensitive individuals or at very high doses, the following can occur:

  • Insomnia: While PS usually helps sleep by lowering cortisol, for some people, the increased brain activity (neurotransmitter release) can be stimulating. If this happens, take it before 2 PM.
  • Stomach Upset: Gas or bloating can occur, especially with soy-derived PS. (Note: FOG OFF uses Sunflower PS to minimize this risk).

Drug Interactions: What to Watch For

While PS is safe with most medications (including antidepressants and blood pressure meds), there are two specific classes of drugs to be aware of:

⚠️ BLOOD THINNERS

Phosphatidylserine can theoretically enhance the effects of blood-thinning medications like Warfarin or Heparin. While actual cases of bleeding are extremely rare, if you are on prescription blood thinners, consult your doctor before starting PS.

⚠️ ANTICHOLINERGICS

PS increases Acetylcholine (a memory chemical). Anticholinergic drugs (often used for allergies or incontinence) work by blocking Acetylcholine. Taking PS might make these drugs less effective.

Source Matters: Soy vs. Bovine

Historically, safety concerns about PS were related to "Mad Cow Disease" when it was sourced from cow brains. This form is no longer sold.

Today, the main safety concern is Soy Allergy. Many PS supplements are derived from soy lecithin. If you are allergic to soy, you could have an inflammatory reaction.

The Fix: Choose Sunflower-derived PS (like the one in FOG OFF). It is 100% soy-free, non-GMO, and carries zero risk of animal-borne diseases.

Summary

Phosphatidylserine is one of the safest brain supplements on the market because it is bio-identical to your own brain tissue. By choosing a high-quality Sunflower source and sticking to the recommended dose (200mg), you can enjoy the cognitive benefits with peace of mind.

FOG OFF is your safe, clean cognitive choice.

Frequently Asked Questions

Q: Can I take PS while pregnant?

A: While PS is natural, there is not enough clinical data on supplementation during pregnancy. Always consult your OB-GYN before adding any new supplement.

Q: Is it safe for children?

A: Yes. PS has been studied in children for ADHD symptoms with a good safety profile. However, dosages should be adjusted for weight.

Q: Can I take it with Coffee?

A: Yes. In fact, PS can help smooth out the "jitters" from caffeine by blunting the cortisol spike coffee causes.
