Nat Phos
No. 10 · Sodium phosphate
Explore Nat Phos No. 10, also known as sodium phosphate or Natrum phosphoricum, with traditional digestive context, comparisons and practical label guidance.
What is Nat Phos?
Nat Phos is the abbreviated name for sodium phosphate in the Schüssler tissue salt tradition. It is No. 10 in our range. The longer name Natrum phosphoricum also appears in traditional reference material.
This guide explains its identity, the digestive themes associated with it in the tradition and the details to check when comparing preparations. Understanding the full name helps distinguish Nat Phos from the other sodium salts and from similarly named phosphate preparations.

Nat Phos in the tissue salt tradition
Traditional tissue salt literature places Nat Phos within digestive themes and often uses the title “acid neutraliser”. This wording helps explain its place in older reference books and the names used for some preparations.
Those descriptions belong to the traditional framework. They do not establish that the tablets neutralise stomach acid, treat reflux or alter body pH. A traditional heading is a way of organising the literature, rather than a diagnosis or an individual treatment plan.
When exploring the twelve salts, keep the mineral name, historical description and finished product directions separate. The name identifies the preparation; the label provides the information for the particular pack you are choosing.

Understanding the sodium and phosphate names
Nat Phos shares part of its name with several other tissue salts. Reading both parts helps distinguish the preparations:
- Nat Phos is sodium phosphate.
- Nat Mur is sodium chloride.
- Nat Sulph is sodium sulphate.
- Kali Phos is potassium phosphate.
- Mag Phos is magnesium phosphate.
The “Nat” names identify different sodium preparations. The “Phos” names share the phosphate part but have different full identities. Similar spelling does not make the salts interchangeable.
This comparison is a reading aid for the ingredient library. It is not a recommendation to combine preparations or choose one from a symptom alone.
Reading a Nat Phos label
The salt number, preparation strength and tablet count describe different things. No. 10 identifies Nat Phos in this range. A potency or dilution notation describes its preparation, while a tablet count tells you how many tablets are supplied.
No. 10 does not mean ten tablets. A potency notation is not a nutritional amount in milligrams. A tissue salt should not be assumed to provide a dietary dose of sodium or phosphorus.
The current individual product description does not specify its dilution or complete tablet base. Check the actual packaging, or ask us to confirm those details before ordering. An ingredient list from another brand, market or format may not apply to the pack you are choosing.
The traditional title also does not make this preparation interchangeable with an antacid or other product containing sodium phosphate. Always follow the directions for the specific finished product.

View Nat Phos tablets and product details →Choosing, using and storing your tablets
Read the full ingredients, including the tablet base and any allergen information. If you avoid lactose, dairy or another ingredient, the mineral name alone cannot establish whether a finished tablet meets your needs.
Follow the amount, frequency and method on the pack, including any age guidance. Check individual suitability with an appropriate practitioner during pregnancy or breastfeeding, when taking medication or when choosing for a child. Persistent or worsening digestive symptoms deserve individual assessment.
Keep the container tightly closed in a cool, dry place away from sunlight and heat. Store out of reach of children and retain the packaging so that the directions and batch details remain available.
Nat Phos questions answered
What is Nat Phos?
Nat Phos is sodium phosphate in the Schüssler tissue salt tradition. It is No. 10 in our range and is also known as Natrum phosphoricum.
Why is Nat Phos called the acid neutraliser?
Acid neutraliser is a traditional descriptive title used in tissue salt literature. It explains its historical association with digestion, rather than establishing that the tablets neutralise stomach acid or change body pH.
Is Nat Phos the same as Nat Mur?
No. Nat Phos is sodium phosphate, while Nat Mur is sodium chloride. They are separate preparations within the tissue salt system.
Is Nat Phos the same as Kali Phos?
No. Nat Phos is sodium phosphate and Kali Phos is potassium phosphate. The shared Phos abbreviation does not make them interchangeable.
Does No. 10 mean ten tablets?
No. It identifies Nat Phos in this range. Follow the amount, frequency and method stated on the finished pack.
