FWIW, my Pure Bulk taurine powder, a 1/2 tablespoon is 6g.

looks like I’m pretty light on my current dose…

So what is the appropriate dose and does it vary by age and gender? I just increased morning Taurine from 2 to 3 grams, wondering if I should go to 4 – or higher?

From what I know, people take from 1 to 6g.
I chose 6g based on being vegan and knowing I was probably deficient… and hoping it would give me Agetron bone results… which it didn’t.

Your bone scan results intrigue me.
I have also been taking a teaspoon of taurine in my coffee every morning for about 3 years. Never had a bone scan before, though. I need to book one in to see what’s going on.

Yes…I’d say its about 15 grams.
So cheap… why not go with a big dose

Ahhhhh, so when you say teaspoon, you don’t mean an actual tsp… you mean silverware tsp… I was wondering why you were taking such a tiny dose…. 1/2 a tablespoon (a measuring spoon) is 6g (it might vary slightly from brand to brand based on how fluffy) .

For cooking purposes, a teaspoonful is defined as 5 mL.
An international metric tablespoon is exactly 15 mL, about 0.53 imperial fluid ounce or 0.51 US fluid ounc

Yes, I use a normal silverware sized spoon. Not a soup spoon.

Because i didn’t know how much one should be taking until this thread… The bottle’s instructions said one a day…

I see.
I use bulk supplements powder from Amazon. Lasts a long time and cheap.

I take taurine but have lowered the dose to ~2,000 mg/day because two 2025 papers directly challenge the foundational claims underlying the taurine geroprotective case.
A longitudinal study directly disputes the earlier Yadav/Singh et al. 2023 Science paper, which had found taurine declining with age in humans, mice, and monkeys and shown lifespan extension in mice with supplementation. C&EN
The key findings: in blood samples from humans, monkeys, and mice, including longitudinal data from the Baltimore Longitudinal Study of Aging (ages 26–100), found circulating taurine levels often increased or remained constant with age. Crucially, within-individual differences in taurine levels frequently exceeded age-related changes, and taurine levels were inconsistently associated with health outcomes across age, species, and cohorts. National Institutes of Health. In fact, taurine levels increased as women aged. The researchers concluded that the association between taurine levels and functional health status measures depended heavily on genetics and context. Inside Precision Medicine
A cell-based study, with all its strengths and limitations, found that circulating taurine levels were not associated with aging, muscle mass, strength, power, physical performance, body composition, insulin sensitivity, or mitochondrial function in humans Wiley Online Library. This is a comprehensive null result across exactly the outcomes that made the 2023 paper compelling. They concluded that taurine deficiency is therefore unlikely to be a primary driver of aging in humans, and these findings challenge its utility as a biomarker of aging and functional decline. This study does not rule out potential positive health impacts of taurine supplementation in older adults, especially in individuals with low circulating taurine levels and those with chronic diseases.
These studies warrant a meaningful downgrade of the case for taurine supplementation. The central pillar of the taurine geroprotective case was the Singh et al. finding of age-associated decline with the logic being that supplementation restores a deficient state. If circulating taurine does not reliably decline with age in humans (and may increase in women), the interventional rationale weakens considerably. Some resolution could be had by measuring taurine levels. Has anyone done that and do intelligent benchmarks exist?

Whether taurine declines with age is irrelevant. The question is whether supplementing taurine provides any benefit
