The longevity supplement industry alone is worth $150 billion a year. Every morning, an Instagram post or podcast pops up promising you a new magic supplement that will turn you into a 30-year-old at age 60. The problem: most of these supplements have not undergone serious clinical research, or if they have, their effects are negligible. A comprehensive report published on MSN, based on a review of evidence by gerontology and pharmacology experts, distinguishes between what actually works and what you're simply throwing money away on.
10 Supplements Not Worth the Money
1. Oral Collagen
Sold as a supplement for skin, joints, and hair. The problem: collagen is a large protein that breaks down into amino acids in the digestive system. The body cannot "rebuild" collagen in the skin from collagen you ate - it uses the amino acids for whatever protein is needed. Eating chicken breast will give you the same results at a lower cost.
2. Resveratrol at Standard Dose
This is the supplement that "discovered" anti-aging following research on red wine. The problem: the dose needed to achieve an effect in animal studies is equivalent to 1,000 glasses of wine a day. Standard supplements contain 100-500 mg - well below the effective threshold. Oral bioavailability is also very low.
3. Vitamin E as a Separate Supplement
Once considered a life-saving antioxidant. A meta-analysis of dozens of studies showed increased mortality in supplement users compared to control groups. Vitamin E from food - excellent. As a supplement - dangerous.
4. Generic Antioxidants ("Everything-in-One")
Supplements containing a blend of 30 different antioxidants. The body doesn't need every antioxidant - some actually interfere with cellular repair processes. Low-dose free radicals are cellular signaling molecules. Their aggressive destruction harms hormesis - the stress adaptation process that strengthens cells.
5. Ginseng as a Daily Supplement
Ginseng is excellent for short-term results (energy, concentration). But there is no solid evidence it affects longevity in humans. Most studies are short-term and have small sample sizes.
6. Oral Glutathione
Sold as the "master antioxidant." The problem: glutathione is destroyed in the digestive system. An oral supplement hardly reaches the bloodstream. Expensive IV glutathione injections are also unproven to improve longevity.
7. Ginkgo Biloba
Sold for memory and cognitive function. A large 2019 meta-analysis of over 3,000 participants: no significant effect on cognition in healthy adults or those with mild decline.
8. Excessive Selenium Supplements
Selenium is needed in tiny amounts - 55 mcg per day. Doses above 200 mcg per day have been shown to increase the risk of type 2 diabetes. Most Israelis get enough from their diet.
9. "DNA Supplements" and Commercial Genetic Tests
Companies like 23andMe sell supplements "personalized to your DNA." There is no scientific evidence that their dietary recommendations are based on more solid data than general advice.
10. Coconut Oil as a Health Supplement
Coconut oil is 90% saturated fat. The AHA and the Gerontological Society say it clearly: there is no evidence that supplementing with it is beneficial for longevity. It is more harmful than good for the heart. Olive oil? Completely different - it is actually recommended.
10 Supplements That Actually Work
1. Vitamin D
Deficiency is especially common in older populations (in Israel, despite the sun - due to less time outdoors). Solid evidence for bone health, immune system, and mood. 1000-2000 IU per day is safe and beneficial.
2. Omega-3 (EPA + DHA)
Anti-inflammatory, protects the brain and heart. The large VITAL study showed a reduction in mortality and heart attacks. Dosage: 1-2 grams EPA+DHA per day. Preferably from high-quality fish oil or algae.
3. Magnesium
Essential for 300 enzymes in the body. Deficiency is common in older adults, manifesting as fatigue, cramps, poor sleep. 300-400 mg per day of magnesium citrate or glycinate (not oxide).
4. Creatine
Became the most scientifically established sports supplement. Studies also show cognitive benefits in older adults. Helps prevent sarcopenia. 3-5 grams per day, daily.
5. NMN / NR (Niacinamide)
Controversial but with solid evidence in animals, and beginning to show promising human results. Restores cellular NAD+. Dosage: 250-500 mg per day. An expensive supplement but with a scientific basis.
6. Vitamin B12
Deficiency in 15% of people over 60 (decreased absorption). Essential for the brain and immune system. 500-1000 mcg per day in older adults, even without a blood test, is safe and effective.
7. Calcium (When Deficient)
Recommended only when proven dietary deficiency exists. Check based on diet - if less than 1000 mg per day from food, then consider a 500 mg supplement. Must be combined with vitamin D.
8. Melatonin
At low doses (0.3-1 mg) improves sleep quality. Effectiveness increases with age (over 55) because our bodies produce less. Quality sleep = clear anti-aging benefit.
9. Specific Probiotics
Not all probiotics. Specific strains (like Lactobacillus rhamnosus GG, Bifidobacterium lactis) show solid benefits. Effects on systemic inflammation, mood (gut-brain axis), and immune health.
10. Folic Acid
Especially essential after age 50 - deficiency is linked to increased homocysteine, a risk factor for stroke and Alzheimer's. 400 mcg per day is safe. Preferably in methylfolate form for those with MTHFR genetic variants.
How to Identify a Worthy Supplement Yourself
- Look for meta-analyses, not individual studies. PubMed is your friend.
- Large number of participants: A group of 30 people is not enough.
- Human studies, not just mice.
- Placebo-controlled: Studies without a placebo are not worth much.
- Supplement quality: Reputable companies with third-party testing (USP, ConsumerLab).
- Be wary of promises: Anything that "reverses aging" - be suspicious.
The Bottom Line
Dietary supplements are not magic. They complement good nutrition and physical activity, not replace them. If you are spending more than $50-75 a month on supplements, you are likely paying for marketing, not science. Investing in the 10 supplements that work will cost you about $30-40 a month and provide maximum benefit.
