Ashwagandha Complex | 400mg KSM-66® with Cordyceps, Ginseng & B Vitamins

Ten botanicals, four B vitamins, and a strain of ashwagandha you can actually look up.

What's in each capsule

  • Niacin, pantothenic acid, vitamin B6 and vitamin B12 all contribute to the reduction of tiredness and fatigue — four separate nutrients carrying the same claim, every one well above the threshold.
  • Pantothenic acid contributes to normal mental performance, and to the normal synthesis and metabolism of steroid hormones, vitamin D and some neurotransmitters — 10mg, 168% NRV.
  • Niacin, vitamin B6 and vitamin B12 contribute to normal psychological function and to the normal functioning of the nervous system — 20mg (125% NRV), 2mg (143% NRV) and 25µg (1000% NRV).
  • Vitamin B6 contributes to the regulation of hormonal activity and to the normal function of the immune system.

And the botanicals

400mg KSM-66® ashwagandha root extract — a named, branded, root-only extract produced without alcohol or synthetic solvents, so you can research the exact material rather than an unspecified "ashwagandha extract".

Alongside it: cordyceps mushroom 200mg, panax ginseng 200mg, Peruvian maca root 200mg, deglycyrrhizinated liquorice root 100mg, black pepper 52mg, reishi mushroom 25mg, schisandra chinensis 25mg, gotu kola 5mg and turmeric 5mg. Every one declared by weight as an extract equivalent — no unnamed blend hiding the small doses.

⚠️ Not suitable during pregnancy or breastfeeding. If you take medication — particularly for thyroid conditions, blood pressure, blood glucose, or any sedative or blood-thinning medicine — speak to your doctor or pharmacist first.

The ashwagandha does not originate from the UK. Blended and encapsulated here in a GMP-certified facility. 90 capsules, vegan, and covered by our 60-day money-back guarantee — even if the pot is half empty.

Your Wellness Journey

From where you are now, to where you want to be — with consistent support.

Where you are now

You've read about ashwagandha and you'd rather buy from someone who tells you the dose and is straight about what the herb is and isn't allowed to claim.

Take it daily

1 capsule, 1 to 3 times per day, or as required. Water is fine. Suitable for daytime use.

Make it a habit

B vitamins are water-soluble and aren't stored, so a steady daily intake matters more than any single dose. Same time each day is the easiest way to keep it going.

Stay stocked

90 capsules per pot — a month at three a day, three months at one. Reorder before you run out.

Before you Buy

The questions we hear most — answered straight.

Ashwagandha KSM-66 supplement bottle by The Health Improvers
What is KSM-66® ashwagandha, and how much is in here?
KSM-66® is a branded, root-only extract of Withania somnifera, produced without alcohol or synthetic solvents. There's 400mg per capsule in this formula, taken 1 to 3 times a day. We use a named extract rather than an unspecified one so you can look up exactly what you're taking — though it carries no authorised health claim in Great Britain, so we can't tell you what it does.
Is this suitable for vegans?
Yes. The capsule shell is hydroxypropyl methylcellulose (HPMC), a plant-based cellulose rather than gelatine, and every other ingredient is plant-derived or a vegan-suitable synthesised vitamin.
Can I take this during the day?
Yes — there's nothing in the formula intended to make you drowsy, and the directions allow 1 to 3 capsules across the day. The four B vitamins contribute to the reduction of tiredness and fatigue, and pantothenic acid contributes to normal mental performance, which is why the pot is labelled the way it is.
Who shouldn't take this?
It's not suitable during pregnancy or breastfeeding. The formula contains ashwagandha, panax ginseng and liquorice root, all of which have recognised cautions. If you take medication — particularly for thyroid conditions, blood pressure, blood glucose, or any sedative or blood-thinning medicine — or you have a medical condition, speak to your doctor or pharmacist first. This is a food supplement, not a treatment for anything.
What's in this besides the ashwagandha?
Nine further botanicals — cordyceps mushroom (200mg), panax ginseng (200mg), Peruvian maca root (200mg), deglycyrrhizinated liquorice root (100mg), black pepper (52mg), reishi mushroom (25mg), schisandra chinensis (25mg), gotu kola (5mg) and turmeric (5mg) — plus vitamins B3, B5, B6 and B12. The vitamins are the ingredients carrying the authorised claims; the botanicals are declared by weight so you can see precisely what's in the capsule.
