One of the best companies I have bought products from. Their products are always high quality (my 6 monthly bloodwork proves this) and the liquid options they offer make taking them really easy.

Metabolics is always my 'go-to' company for supplements because I fully trust quality & purity of the ingredients they source to make the supplements. Also, I value the prompt response and advice they provide if I'm unsure exactly which variation of a particular vitamin or other supplement to buy.

Frequently Asked Questions

What is a herbal tincture?

A tincture is a liquid extract made by steeping a plant in a solvent to draw out its active constituents, then filtering out the plant material. The result is a concentrated liquid that you measure in drops or milliliters using the dropper in the lid. Because there is no capsule to break down, tinctures are quick to take and simple to combine with water or juice.

How do I take a tincture?

Add the recommended number of drops to a small amount of water or juice, or take directly under the tongue if you prefer. The suggested amount is on every label and product page. Many people find it easiest to take tinctures with a meal, and to keep the bottle where they will see it, such as next to the kettle, so it becomes part of a routine.

Can I adjust the dose?

Yes, and that is the main reason practitioners like the format. Start at the lower end of the label guidance and increase gradually if needed. Do not exceed the stated daily amount without advice from a practitioner. If you are pregnant, breastfeeding, taking medication or have a health condition, check with a healthcare professional before starting.

How should I store tinctures, and how long do they last?

Keep them in a cool, dark place with the lid tightly closed, out of reach of children. The bottles are amber glass to protect the contents from light. Each product has a best-before date on the label; once opened, use within the period stated on the pack.

Tincture or capsule: which should I choose?

Both deliver the same botanical. Capsules are convenient and taste-free, so they suit people who want a fixed daily amount with no measuring. Tinctures suit anyone who wants to control the dose precisely, dislikes swallowing capsules, or is supporting a client who needs a gradual introduction. Several of our botanicals, including turmeric and ginger, are available in both formats, so you can choose whichever fits.

Website was very easy to use. I found what I had been recommended to get, and read the blurb to double-check the ingredients and instructions. The quality and value for money is hard to compare when you consider most other brands have additional ingredients, bulking agent(s) and additives! Ordering and paying was simple too. Delivery was on targets and updates were sent during the process.

I’ve used Metabolics products for many years because of their quality, purity, and freedom from unnecessary ingredients (eg fillers, artificial preservatives, synthetic excipients). They are in forms that are readily absorbed and bioavailable. The products are well designed, with an up to date awareness of current knowledge regarding metabolic pathways and the growing science of nutrigenomics. I have always found the team friendly and helpful, and the service first class. I have no hesitation in recommending them to anyone who is serious about wanting to be well!
