How much choline per day

Too much can be harmful

Consuming too much choline has been associated with unpleasant and potentially harmful side effects. These include drops in blood pressure, sweating, fishy body odor, diarrhea, nausea and vomiting ( 65 ). The daily upper limit for adults is 3,500 mg per day.

Eggs are one of the best sources of choline, with 1 egg providing 147 mg. This means that eating just 2 eggs per day covers 54% of the Recommended Daily Intake (RDI) ( 3 ). The choline content of an egg is almost entirely concentrated in the yolk.

If you aim for a diet filled with whole plant foods, you may come pretty close to meeting your choline needs, as evidenced in my sample meal plan. Adult women should aim for 425 mg per day, and men for 550 mg per day. Orangesicle Popsicles contain choline, compliments of oranges, bananas, and soymilk.

One Capsule of choline should be taken before breakfast or lunch.

When taken by mouth: Choline is likely safe for most people when taken in doses below 3.5 grams daily. Taking high doses of choline is possibly unsafe. Taking doses over 3.5 grams daily might cause side effects such as sweating, a fishy body odor, diarrhea, and vomiting.

Choline is also crucial for collagen synthesis; choline is a B-vitamin that gets converted into glycine – one of the amino acids needed for collagen synthesis. Good sources of choline are eggs, navy beans, turkey, salmon, and cauliflower.

Choline deficiency as a cause of hepatic steatosis is exemplified in the setting of total parenteral nutrition, in which choline replacement led to a reversal of fatty infiltration (23). Furthermore, dietary choline deficiency is routinely used in animal models of NAFLD (24).

CHOLINE AND THE BRAIN

Choline has a critical role in neurotransmitter function because of its impact on acetylcholine and dopaminergic function. Studies in animals suggest that CDP-choline supplements increase dopamine receptor densities and can ameliorate memory impairment.

You should not use choline if you have bipolar disorder. Women who are enceinte or breastfeeding should talk to their healthcare providers before taking any supplements. There are no known interactions between choline and any food or medicine. People with low folate levels may need more choline.

Choline for hair growth includes numerous choline hair benefits along with other key health benefits. A lack of this macronutrient can contribute to dull hair, thinning hair, hair loss and baldness. This makes choline a choice supplement for anyone doing all they can to support optimal health.

Changes in plasma levels of choline or of certain amino acids lead to changes in brain levels of the precursors for these neurotransmitters—choline for acetylcholine, tryptophan for serotonin, and tyrosine for the catecholamines.

Conclusion: In this large population-based study, choline concentrations were negatively associated with anxiety symptoms but not with depression symptoms.

In humans choline bitartrate increases choline blood plasma levels within 1 hour after ingestion [57, 58] and with brain concentrations peaking around 2 hours until at least up to 3 hours after ingestion [59, 60]. Choline’s effects on the cholinergic peripheral system peaks between 1 and 2 hours after ingestion [46].

Choline treatment for sleep disturbances

The results suggest that lower choline intake is associated with higher levels of sleepiness, or that lower choline intake is simply associated with more sleep, leading to less sleepiness.
