Protein Powder · Whey / Casein / Plant Protein
Adequate protein is the single strongest longevity intervention after exercise.
Short answer
Whey isolate best for muscle protein synthesis. Plant-based need 20% more due to lower leucine.
Product and dose overview
Protein Powder (Whey / Casein / Plant Protein) is a foundational / muscle with evidence grade A, meaning it is well-supported by replicated human trials. We track 0 products containing Protein Powder. The top-ranked product scores 0 out of 10 on our composite scale (dose, evidence, price, testing, transparency). Prices range up to $0.00 per month.
What it is
Concentrated protein from milk, soy, pea, or other sources. Supplements what most people don't get enough of, especially over 60.
Why people take it
Maintaining muscle mass is one of the strongest predictors of healthy aging. Older adults typically need 1.2 to 1.6 g/kg body weight, and often fall short from food alone.
Our verdict
Whey isolate best for muscle protein synthesis. Plant-based need 20% more due to lower leucine.
Structure & class
Whey (fast), casein (slow), soy, pea, rice.
Mechanism & clinical data
Multiple meta-analyses confirm mTOR/muscle-protein-synthesis effects of 20 to 40 g leucine-rich protein.
Pharmacokinetics
Digestion-dependent.
Dose & forms
What to watch out for
Sucralose/artificial flavour common. Look for third-party heavy-metals testing (esp. plant-based).
Where this dose comes from
The trial dose above is our editorial pick from the published human trials for this ingredient. We choose the dose that the best-available studies used on the endpoint most relevant to longevity. The range shows the lowest and highest doses tested in published trials. The landmark studies below are the papers we read to set it. You can click through and check our work.
When new trials publish, our automated sweeps flag them. If a new study materially changes the dose, we update it through editorial review and record the old dose, new dose, and the triggering study in every affected product's recommendation history. The dose is never changed automatically.

EU Court sharpens the bar for botanical health claimsA Court of Justice of the European Union ruling in April 2025 further tightened the requirements for how botanical ingredients (herbs, plant extracts) can be marketed with health claims in the EU, effectively removing much of the flexibility of the on-hold list.

EU report identifies 117 supplement substances as potential health risksThe HoA Working Group on Food Supplements (26 European countries) published its first report evaluating 117 substances used in food supplements. Of these, 65 were assessed as likely novel foods, 6 were already regulated, 34 had insufficient data, and 12 were prioritized for Article 8 restriction under Regulation (EC) No 1925/2006. The 12 priority substances include ashwagandha, curcumin, melatonin, piperine, St. John's wort, coumarin, p-synephrine, maca, holy basil, Melaleuca, black cohosh, and L-tryptophan. The report drew on 1,500 RASFF alerts reviewed between 2017 and mid-2022.

EU Health Claims Regulation adoptedRegulation (EC) No 1924/2006 laid down harmonised rules for nutrition and health claims made on foods, including supplements. Only claims listed in the EU Register of authorised claims can be used. Rejected botanical claims are held in a separate on-hold list.
-
EU introduces the Novel Food RegulationRegulation (EC) No 258/97 required any food or food ingredient without a history of consumption in the EU before 15 May 1997 to be authorised before being placed on the market. This is the framework that captures NMN, spermidine as a supplement ingredient, urolithin A, and many other longevity actives.
