The claimWhat Jack actually said
In an April 2018 interview, Nicklaus disclosed that he had travelled to Munich in February 2016 for an experimental stem cell procedure involving liposuction followed by a series of spinal injections. He said the pain he used to feel while playing had subsided after a few months, and prefaced his forecast about orthopedics by noting he is not a doctor. He also mentioned planning a further treatment for his shoulder.

Why it mattersWhy this matters for longevity
Chronic back pain is one of the largest causes of disability worldwide, which makes it a prime market for treatments that outrun their evidence.
Clinics marketing stem cell procedures directly to consumers operate with limited oversight, and prices run into thousands of dollars per session.
A famous person's recovery story travels much further than the review paper that qualifies it.
The evidenceWhat the science says
Systematic reviews of intradiscal regenerative therapies, including mesenchymal stem cell preparations, do report improvement in pain and function for some patients with chronic discogenic low back pain. The reviews grade this evidence as limited, and the underlying studies are typically small, frequently uncontrolled, and heterogeneous in how cells are sourced, prepared and injected, which makes pooling them difficult and comparison across clinics unreliable.
What the evidence does not support is the leap from those results to a transformation of orthopedics. There is no large randomised trial establishing durable benefit over sham injection, and back pain naturally waxes and wanes, so an improvement appearing months after a procedure is precisely the pattern that requires a control group to interpret. Published surveys of the direct-to-consumer stem cell industry describe widespread marketing of unproven indications, and Nicklaus himself flagged that he is not a doctor.
TakeawayThe honest takeaway
The practical lesson
If a clinic offers stem cells for back pain, ask what randomised evidence exists for your specific condition before asking what it costs.

SupplementsThe supplement angle: Vitamin D and magnesium
Support a habit, do not replace one
Vitamin D and magnesium are often suggested for musculoskeletal pain, and the trial evidence for either as a back pain treatment is weak. They are worth discussing with a clinician for deficiency rather than as a substitute for rehabilitation.
Supplements can support good habits. They do not replace sleep, movement, nutrition, or medical care. Talk with your healthcare provider before starting anything new.
