The pet supplement market is crowded with bold claims and fashionable ingredients. Some are genuinely useful. Others are more marketing than meaningful support. For owners trying to make informed decisions, understanding which ingredients have credible rationale and which do not - is essential.
This guide breaks down common ingredients found in dog supplements, explains what they do in plain English and highlights what is worth paying for. It also shows how these ingredients appear within PawStrong formulations.
Why Ingredients Matter More Than Headlines

What About Turmeric and Curcumin?
Turmeric is one of the most talked-about ingredients in human and pet supplements. However:
What turmeric is
A spice containing curcumin, known for its antioxidant properties.
Limitations in dogs
- Curcumin has low natural bioavailability.
- Requires specific forms (e.g., complexed curcumin) to be effective.
- Results vary widely.
- Often included at levels too low to be meaningful.
Worth paying for?
Only when used in a properly formulated joint product with enhanced bioavailability.
Most “turmeric chews” on the market are not meaningfully dosed.
PawStrong does not use turmeric for these reasons - opting instead for ingredients with clearer applicability and more predictable consistency.
How to Decide What’s Worth Paying For
A simple, sceptical checklist:
- Does the ingredient have a defined physiological role?
- Is it included at a meaningful level?
- Does the form used support absorption?
- Is the ingredient appropriate to the health goal of the product?
- Is the supplement a complete formula or a random list?
- Is the dosage easy to give every day?
If the answer is “yes” to all of these, the supplement is more likely to be worthwhile.
How PawStrong Uses Ingredients Responsibly
Across the range, PawStrong prioritises:
- Ingredients with a clear purpose
- Meaningful inclusion levels
- Hypoallergenic, cold-pressed soft chews for ingredient protection
- Evidence-aware formulation
- Avoidance of unnecessary “trend” ingredients
- Clear feeding guidance and predictable accurate dosing
Each product targets a specific need, daily health, digestion, skin, joints, calmness or senior vitality - rather than attempting to be a cure-all.
