What is Shatavari SRI-81®?

Inside these Shatavari capsules is SRI-81®, a patented Shatavari root extract from Indian asparagus. It is obtained from the root only, not from the leaves. The root-to-extract ratio is 13:1. So one part extract comes from thirteen parts root.

The extract is standardised to at least 10 % total shatavarins, tested by HPLC. That is exactly what sets it apart from ground powder. Every capsule delivers the same amount of plant compounds, batch after batch.

What are shatavarins and shatavarin IV?

Shatavarins are the characteristic saponins of the root. 300 mg of SRI-81® Shatavari extract contains 30 mg shatavarins, of which 15 mg is shatavarin IV. Shatavarin IV is the best-described single saponin of this plant. The content is HPLC-tested and does not vary from batch to batch.

What Shatavari does in the body

Shatavari is one of the adaptogens. These are plants that help the body cope better with stress. For you that means more calm on dense days.2

In Ayurveda this plant has been used for over 3,000 years. Ayurveda calls it the Queen of Herbs and lists it as a Rasayana. A Rasayana is a restorative, here for female balance. This tradition now meets standardised extracts.

You know the days when everything pulls at once. In a placebo-controlled study, women took 300 mg of Shatavari root extract daily for eight weeks. They felt less stressed than the placebo group and reported fewer hot flushes.2 Fatigue and drive also developed more favourably.

Such changes come quietly. SRI-81® Shatavari does not show on day two. It shows in the fourth week, when less throws you off balance.

Shatavari capsules with 300 mg of pure root, nothing else

The difference from usual Shatavari products lies in what is missing. One SRI-81® capsule contains 300 mg of root extract, rice flour and a plant-based shell. Nothing else. Other Shatavari capsules stretch the extract with zinc, vitamin B6 or inulin. For the same amount of root you need three capsules there. What sounds like an effect on their label often comes from the zinc.

Intake: when do you take one capsule, when two?

One capsule is the daily base. Two capsules are meant for demanding phases. The consumption recommendation allows both.

One capsule: the daily base

One SRI-81® Shatavari capsule (300 mg) covers your day. The perimenopause study ran on exactly this amount over eight weeks.2 Take it with a meal, then it sits lightly in the stomach.

Two capsules: for demanding phases

Two capsules (600 mg) deliver twice the shatavarins, so 60 mg instead of 30 mg. Split them between morning and evening. That keeps the intake steady rather than a single morning peak. It pays off as menopause approaches. Or when training blocks are dense and the weeks are full.

In practice, for your intake: start with one capsule for two to four weeks. Whoever needs more goes to two. More than two capsules a day is not intended. One tin lasts you two months at one capsule and one month at two.

Premium quality: tested, pure, made in Germany

Premium here means a patented branded raw material with a fixed standard. SRI-81® comes from Ixoreal Biomed, the company behind KSM-66® Ashwagandha. The extract is obtained from the root only, at a 13:1 ratio. It is standardised to at least 10 % total shatavarins, tested by HPLC. Five published human studies have examined this exact raw material.1,2,3,4,5

Genetic Nutrition processes it in Germany, laboratory-tested and 100 % vegan. Without added vitamins, minerals or flavourings. You see this quality in the declaration: every ingredient is named, every amount tested.

Stronger as a duo: SRI-81® Shatavari and Ashwagandha KSM-66®

Two plants from Ayurveda, two sides of the same day. Shatavari supports female balance, KSM-66® Ashwagandha the handling of stress. In two studies the combination performed better than the Shatavari extract alone.3,4 For you that means calmer days and a calmer wind-down in the evening.

One capsule each per day: KSM-66® Ashwagandha in the morning, SRI-81® Shatavari in the evening. You will find the partner here: Ashwagandha KSM-66® with 120 capsules.

Goes well with it: Magnesium citrate for the evening and Iron with vitamin C. More in the Adaptogens collection.

Frequently asked questions

How long does one tin of Shatavari capsules last?
Two months at one capsule a day, one month at two. 60 capsules are 60 full daily doses of 300 mg each. No calculating, no leftover powder in the tin. Two months is exactly the period from the published studies. If you go to two capsules in a demanding phase, it is best to keep the second tin ready straight away.

Are these Shatavari capsules vegan?
Yes, completely. These Shatavari capsules contain the root extract from Asparagus racemosus, rice flour and a plant-based shell made of hydroxypropyl methylcellulose. Nothing else. Many Shatavari capsules with zinc or vitamin B6 are not vegan despite a plant base. Individual ingredients there come from dairy processes. You avoid that discussion entirely here.

How long does it take before I notice something?
Reckon with four weeks, not four days. In the perimenopause study the women took 300 mg daily for eight weeks. The first measurement was after four weeks. SRI-81® Shatavari works through daily repetition, not like a single tablet. Whoever stops after a week has never really tested the extract.

Can I combine Shatavari with Ashwagandha?
Yes, and that is exactly what two of the five studies did. The combination performed better there than the Shatavari extract alone. Both branded raw materials, SRI-81® and KSM-66®, come from the same company. KSM-66® Ashwagandha in the morning against the pressure of the day, SRI-81® Shatavari in the evening for balance.

Are Shatavari capsules useful for female athletes?
Yes, because hard training is stress for the body. Shatavari is an adaptogen, and in the placebo-controlled study the extract showed better stress values than placebo. In dense training blocks many female athletes take two capsules a day, so 600 mg. There are no added vitamins and no flavourings in it, just the root.
