How long does shatavari take to work?

Quick answer

It depends on what was measured. Menopause trials saw rating scores fall by week 4 and further by week 8, and muscle trials ran 6 to 8 weeks. Most trials stopped at 8 weeks, so nobody knows how long shatavari can safely be taken.1,2

Key facts

  • In the newest milk trial, mothers took 300 mg of extract twice a day for the 72 hours after birth.3
  • Grip strength was measured after 6 weeks of root powder.2
  • In one menopause trial, rating scores had fallen 43% by week 4 and 71% by week 8.1

What changed, and when

When shatavari trials measured results1,2,4,5,6
What was measuredWhen results were checkedDaily amount
Menopause rating scoresWeek 4 and week 8100 to 500 mg of extract
Grip strength after menopauseWeek 61,000 mg of root powder
Strength with trainingWeek 8500 to 1,000 mg

In menopause trials, rating scores had already fallen by week 4 and fell further by week 8.1,7

Milk trials measured results 72 hours after birth, and an older trial measured prolactin after 30 days.3,8,9

Muscle trials lasted 6 to 8 weeks: grip strength was measured after 6 weeks, and training gains over 8 weeks of lifting.2,5,6

Why early changes are hard to read

In a 135-woman menopause trial, women on placebo also reported improvement over 8 weeks, and quality of life scores ended up no different between the groups. The trials were short, and most were run with help from an extract's maker, so a quick change on a rating scale is weak evidence on its own.7,10

How long the trials lasted

No trial checked results after a single dose. Each one gave shatavari daily for weeks and measured the outcome at the end, so the trial length is the best guide to how long any change took to show.

Recent trials of standardized root extracts used 100 to 600 mg a day, most often one 300 mg capsule a day for 8 weeks.1,3,7,10

Two UK trials gave 1,000 mg of root powder a day, as two 500 mg capsules, for 6 to 8 weeks.2,6

Because the trials stopped at 6 to 8 weeks, they say nothing about what happens over months or years of use.2

Powder or extract: does one work faster?

No trial compared them. Root powder was studied for 6 to 8 weeks in strength trials and for 30 days in nursing mothers, while extracts were studied for 3 days to 8 weeks, so speed cannot be compared across forms.2,3,6,9,10

How long can shatavari be taken?

Most trials lasted 8 weeks or less, so the effects of longer use are unknown.2,10,11

A long history of traditional use is not the same as tested safety. With no safe upper amount set and few trials past 8 weeks, talk to your doctor if you plan to take shatavari for longer, and stop if you notice side effects.11

Questions people ask

Does shatavari powder take longer to work than capsules?

No trial compared them. Both were taken for weeks before results were measured, except in the milk trials, which used extract capsules for 3 days.2,3

How long can shatavari be taken safely?

Nobody knows. Its long-term safety has not been studied, so if you want to take it for more than a couple of months, talk to your doctor first.11
