PDM vs Vegan PDM: Which Herbalife Protein Drink Mix Should You Buy?

Protein Drink Mix (PDM) and Vegan Protein Drink Mix are both used the same way — added to a Formula 1 shake to boost protein. The only real difference is the protein source. This guide explains which to choose.

Quick answer: Choose standard PDM (£30.96, 588g, ~40 servings, ~£0.77/serving, ~15g protein) unless you specifically need a plant-based option. Choose Vegan PDM (£30.96, 560g) if you follow a vegan or plant-based diet. Both cost the same. Neither is needed unless you specifically want higher protein intake — Formula 1 alone provides ~19g protein per serving. All products are genuine Herbalife with fast UK delivery and no minimum order.

Do you actually need PDM?

You need PDM if:

You specifically want higher protein intake — for example, if you do regular weight training, are replacing two meals per day, or have been advised to increase protein. PDM adds approximately 15g protein per serving, bringing the total shake to approximately 34g protein. Choose standard PDM unless you follow a vegan or plant-based diet, in which case choose Vegan PDM.

You do not need PDM if:

You are new to Herbalife and just want to replace one meal per day. Formula 1 alone provides approximately 19g protein per serving — sufficient for most people replacing one meal. Do not add PDM just because it appears alongside Formula 1. Start with Formula 1 alone and add PDM later if you find you need more protein.

Frequently asked questions

What is the difference between PDM and Vegan PDM?

Both cost £30.96, provide approximately 15g protein per serving, and are used the same way — added to a Formula 1 shake. The only difference is the protein source: standard PDM uses whey (dairy-based); Vegan PDM uses plant-based protein (pea/rice). Choose Vegan PDM if you follow a vegan or plant-based diet.

Do I need PDM if I already use Formula 1?

Not necessarily. Formula 1 alone provides approximately 19g protein per serving — sufficient for most people replacing one meal per day. Add PDM only if you specifically need higher protein intake, such as for regular weight training or replacing two meals per day.

Is PDM the same as Formula 1?

No. Formula 1 is a complete meal replacement shake mix (~210 kcal, ~19g protein, 20+ vitamins and minerals). PDM is a protein add-on — it adds approximately 15g protein to your shake but is not a meal replacement on its own.

Should I buy the F1 + PDM Bundle?

Only if you already use both Formula 1 and PDM regularly. The bundle (£104.96) includes PDM and three F1 tubs. If you have not tried PDM before, buy them separately first.

How do I use PDM?

Add one scoop of PDM to your Formula 1 shake along with two scoops of Formula 1 and 250–300ml milk. This brings the total protein to approximately 34g per shake. Check the product label for exact serving guidance.
