Choline Supplement Review

Read this Choline supplement review guide to know more about its types, dosage guide, its benefits, possible negative effects, interactions, its comparisons with the famous king of nootropics — modafinil, and the most useful brands of choline supplement available today in the market.

Like methionine (found in fish, meat, & also dairy products) which plays a crucial role in the many functions within the body, let’s explore more about the choline supplement in this guide. But first things first!

What Exactly Is Choline?

Choline is an indispensable nutrient comparable to B vitamins, but a pretty impressive one compared to other vital vitamins & minerals. That means it’s neither a vitamin nor a mineral — it’s a remarkable organic compound located predominantly in animal sources such as nuts, beans, meats, fish, & eggs as well as in foods (i.e., vegetables, fruits, & whole grains). It can be made in the liver & is indeed used in considerable chemical reactions in the body.

Choline wasn’t even recognized as a paramount nutrient by the National Academy of Medicine until 1998 [1]. It’s certainly essential in the nervous system & also for the growth of normal brain functioning.

Your brain plus the nervous system require choline to regulate mood, memory, muscle control, & other functions. Additionally, you need this nutrient to form the membranes that encircle your body’s cells.

The phospholipids that line your cell membranes undoubtedly contain choline, & the essential neurotransmitter acetylcholine — as the name implies — contains it as well.

Because choline is fairly new on the nootropic nutrient scene, nootropics enthusiasts seem to value it. It indeed has nootropic properties while supporting to lessen some of the undesirable negative effects linked with some nootropic use — scilicet headaches.


And although we’re always discovering about this new nutrient, undoubtedly there has been a substantial amount of scientific research & reviews on its function in cognitive augmentation, among its several additional advantages. As to how long to work, choline takes about an hour to function, and its brain concentrations peak around 2 up to 3 hours after ingestion.

Choline Types

Several distinguishable types of choline are indeed found in some food (i.e., whole grains, vegetables, & fruits), in your body, or certain supplements. Here’s a list of what you must understand regarding the most standard ones [2]:

  • Choline bitartrate: It’s the most regular supplemental form of choline — about 40% choline by weight, & is incredibly affordable, but not as well-absorbed or used by the body as some different choline forms. It can maintain memory recall, maintain neuromuscular function muscles as you age, & support healthy liver function, etc.;
  • Citicoline: Also understood as cytidine diphosphate-choline (or CDP-choline), it is a widely utilized nootropic & a precursor to uridine, one of the major 5 nucleic acids utilized by the body to build DNA. It has 18% choline & certainly boasts some remarkable cognitive advantages. It undoubtedly aids memory loss due to aging, ameliorates vision in individuals with glaucoma, & also supports recovery in stroke patients. CDP-choline is also utilized for the treatment of Alzheimer’s & Parkinson’s disease, lazy eye, bipolar disorder, as well as other conditions of the brain [3];
  • Phosphatidylcholine: It’s found in most choline foods & is a phospholipid. It contains 13% choline by weight & can augment the neurotransmitter acetylcholine & it may also ameliorate memory function. Understand that phosphatidylcholine breaks down into choline in the body to offer similar choline benefits. It helps ameliorate cognitive function, aids in liver repair, aid ease signs of ulcerative colitis, heighten lipolysis, & help dissolve gallstones, etc. [4];
  • Alpha-glyceryl phosphorylcholine (Alpha-GPC): It’s 40% choline & is a favored choline supplement type among nootropics enthusiasts as it’s well-absorbed & can certainly cross the blood-brain barrier [5];
  • Choline chloride: It’s frequently used in animal feed but is rarely used in supplements created for human use.

Furthermore, choline is also discovered in soy lecithin, & some individuals take lecithin supplements. Certainly, choline supplements stem mood swings, lessen cholesterol, & guard the liver against harm due to booze. They also may lessen blood pressure, heighten memory, & treat Alzheimer’s & Parkinson’s ailments. It may ameliorate athletic performance & may assist thwart neural tube defects in pregnancy as well.

Dosage Guide

The National Academy of Medicine set a guideline about how much choline most individuals need. The guide is known collectively as the Dietary Reference Intakes (DRIs). Choline has an Adequate Intake (AI) level. The AI ensures that most healthy individuals won’t undergo signs of deficiency. The amount of choline you require each day relies on individual age & sex. Average daily suggested amounts are listed below in milligrams (mg) [6]:

Life Stage Advisable Amount
birth to 6 months 125 mg
infants 7 to 12 months 150 mg
children 1 to 3 years 200 mg
children 4 to 8 years 250 mg
children 9 to 13 years 375 mg
teen boys 14 to 18 years 550 mg
teen girls 14 to 18 years 400 mg
men 19+ years 550 mg
women 19+ years 425 mg
pregnant teens & women 450 mg
breastfeeding teens & women 550 mg

However, most people don’t get adequate choline to satisfy the AI level, implying that — between food sources as well as the choline that’s naturally created by the body — they aren’t getting perfectly enough nutrients. Although manifestations of authentic choline insufficiency are rare, many individuals come up short when it comes to choline foods in their diet.

It’s indeed tempting to infer how much better the health of most people would be as a whole if every individual was getting enough of this insanely great nutrient.

Compared to the AI table given above, there is the Tolerable Upper Intake Level (UL). This is the most dosage that an average healthy individual can take without forming to risk the negative effects of choline toxicity. The recommended UL dosage for choline for adults (male, female, pregnant, & breastfeeding) is up to 3,500 mg/day.

Take Pill

Certainly, when selecting your choline dose, it’s most useful to at least use the AI of 425 to 550 mg/day — though that would incorporate choline from all sources, including foods with choline. Undoubtedly, most choline supplements comprise anywhere from 45–100% of the AI for the nutrient.

Choline Benefits

Choline citrate or Nutrasal Cerebra GPC Liquid offers a lot of benefits & you can buy it online (i.e., at Amazon). The well-documented choline supplement benefits are as follows:

  • neuroprotection & cognitive boost: As a structural component of acetylcholine neurotransmitter which communicate signals to & from the nervous system. Acetylcholine carries signals among brain cells & is indeed essential for memory & other brain functions while supporting muscle movement, learning, arousal, working memory, motivation, attention span, & REM sleep;
  • cholesterol management: Choline supplement may also assist to regulate cholesterol digestion & metabolism, as well as keeping excess cholesterol from building up in the liver. This activity could potentially lessen heart disease risk [7];
  • cell membrane structure & function: Choline is indeed a fundamental component of the phospholipids that form cell membranes, especially phosphatidylcholine. These phospholipids form the structural membrane surrounding the cell & also regulate the permeability of cells;
  • protects memory & loss of brain function: It keeps the mind mentally sharp as one ages. It also preserves memory & prevents dementia, memory loss, as well as other signs of cognitive decline as an individual becomes older. It maintains brain elasticity by functioning to maintain the correct levels of acetylcholine, which naturally decreases into old age. Low levels of acetylcholine may certainly lead to cognitive decline, including senile dementia & Alzheimer’s disease [8];
  • helps with exercise performance & muscle function: It indeed helps to enhance mental energy, concentration, & focus, which are all essential for physical activity as well as athletic performance. Choline’s effect on the metabolism & brain neurotransmitters can certainly produce swifter reaction times & lessen the time required for mental processing [9]. The supplement enhances energy levels, individual mood, sleep cycles, as well as recovery time following strenuous activity. Besides, the choline supplement is used in muscle nerve functioning & may indeed be beneficial in controlling fatigue as well as muscle aches or pains following exercise. Certainly, every time a muscle moves within the body, choline is undoubtedly required to activate acetylcholine, which transmits chemical signals to muscles & also makes them mobile;
  • helps support heart health: Choline together with folate helps in the conversion of homocysteine, which thwarts the body from stashing too much fat. It may be advantageous in cutting down on the risk of experiencing a heart attack or stroke [10]. Choline & lecithin can assist to lessen blood cholesterol as well as the risk for heart disease. However, different investigations have yielded conflicting results, so more study is still required before physicians will begin to prescribe choline for its capability to decrease LDL (“bad”) cholesterol & triglycerides [11].

Choline also supports DNA synthesis as well as fetal & infant brain development. Indeed, pregnant women are frequently advised to take choline in complement to their prenatal vitamins. The nutrient is also good for weight loss. It aids the body burn fat, resulting in more effortless weight loss & certainly better metabolic health.

Possible Side Effects

Pills Side Effects

Choline is somewhat free of side effects unless ingested in higher doses. The negative effects of overdoing choline (roughly 20 g) can undoubtedly be undesirable, including things like [12]:

  • extreme saliva production;
  • sweatiness;
  • vomiting.

Also, diarrhea, stomachache, or loose stools can occur at normal doses. High doses may also induce liver toxicity, where the liver is incapable to process such large doses of the nutrient.

Besides, there’s some debate over the healthfulness of free choline because it augments the body’s production of trimethylamine N-oxide (TMAO), which has been connected to heart illness [13]. Fortunately, meals high in choline don’t seem to ameliorate heart disease risk, according to a study of over 184,000 participants [14].

Certainly, choline is probably safe for most individuals when ingested in doses below 3.5 g daily.

Interaction with Meds, Food, and Alcohol

Choline can interact with many drugs such as Nevirapine & Pancuronium, etc. Some interactions can be minor, while others can induce severe interactions [15]. Some interactions can boost or lower serum concentration of another drug. Additionally, there are no available or notable interactions between choline and any other supplements, alcohol, & foods. Also, ingesting the nutrient with atropine might lessen the effects of atropine. On the whole, it’s safe to use choline without mixing with other drugs that might induce drug-drug interaction & unless you are taking massive doses.

Choline and Modafinil

The most favored modafinil stack that aids potentiate the effects of modafinil is choline. Modafinil vs choline stack offers impressive results.

The most typical regular negative effect of modafinil is a headache. Taking it together with choline makes this annoying negative effect vanish.

Armodafinil Tablets

Modafinil enthusiasts can enjoy the “smart tab” benefits if taken with choline because it’s the only thing that functions to overcome its headaches. Besides, there are no interactions between modafinil & choline that would make them unsafe to take together [16].
