I think, in early 20s, healthy living to promote lifespan extension may be more about what you *don't do* than about what you do. Don't step on your own feet, trip yourself up with poor information from hucksters. Don't be your own worst enemy by overdoing unproven supplements.
Assuming you're healthy and eating well to promote RDA, I'd nix all of these supplements (except, maybe -- big maybe -- the B-complex if you're B-deficient). Instead, focus on consistently eating minimally processed plants. If you document your daily eating habits on a program like cronometer, and stick with it, be consistent, you'll save money, frustration, and dashed hopes when the supplements you thought would "do something" to slow aging in fact "do nothing" to slow aging.
Unless you're diabetic, taking metformin in your early 20s is misguided. There just isn't any evidence at all that in normally healthy young people metformin will do anything to lift you out of aging. Metformin may also contribute to male pattern baldness, which you appear to be fighting (e.g., finasteride).
Calorie restriction might help, but CR takes discipline and courage and commitment that most people just don't have. Fasting also might help, but it depends.
As Andey says above, over-consuming vitamin d is possibly harmful. Get blood tests, find the middle of the range, enjoy sunshine. Wear sunscreen. These boring mainstream interventions are all we have for now. Promising future treatments remain, for now, in the future.
Resveratrol with piperine, astaxanthin, astragalus, and extra vitamin c are all wasted money if you eat healthy plant food. Track your diet on an app. Discover your shortfalls. Supplement those daily shortfalls and pay attention to Recommended Daily Allowance.
Until more *human evidence* from multiply replicated, disinterested studies *in humans* prove their worth for whatever complex metabolic pathway you're seeking to target, supplements pitched at you are a waste of money for an early 20s healthy person. Save your money instead, put money away, seek compound interest from your money, time is on your side, so that you'll be able to afford real (expensive) proven regenerative therapies when real proven regenerative therapies become widely available.
The things not to do you already know: don't drink too much booze, don't access too many street drugs, don't have too much unprotected sex, don't sit in too much skin cancer causing sun, don't drive your bike or your car recklessly, don't eat junk food, don't drink junk drinks, don't not exercise, do something worth living for, find your passion. These are the boring, proven truths that few people want to follow.
The flaxseed is good for you. Amla is probably overly hyped, vitamin K2/MK7 might be good -- or just keep on consistently eating leafy greens. Algal supplements or algal oil might be good if you're vegan (and if daily diet tracked on cronometer indicates you're omega 3 deficient). Again: cronometer and dietary consistency are what we have -- until actual real, proven reparative therapie$$$ emerge from mainstream clinical trials (which may be decades away, and even then, wildly priced...)
